MX-9900 HYDROSTATIC
AUTO-FEED WOOD CHIPPER

The WoodMaxx MX-9900 hydrostatic auto-feed chipper is a robust self-feeding PTO wood chipper. This wood chipper is extremely compact, and built to withstand commercial use. The hydrostatic drive system infeed roller will grab and pull material into the chipper head using a powerful hydraulic motor. This motor is powered by the chippers self-contained hydrostatic pump and reservoir. Four (4) High quality (A8 tool steel) made in the USA knives are standard equipment on all MX-series wood chippers. The design of the WoodMaxx MX-series chipper is so unique and innovative that it is now patent pending.

MACHINE 100% ASSEMBLED ON DELIVERY

The WoodMaxx MX-9900 wood chipper comes shipped to you in in a wooden crate and is 100% completely assembled. Simply attach the MX-9900 wood chipper to your tractor, lower the infeed bin, raise the discharge chute, size and attach the PTO shaft (included), and fill the oil reservoir with 2 quarts of 10-W40 motor oil. The WoodMaxx MX-9900 wood chippers is manufactured and assembled right here at our facility and are given a comprehensive 22-point inspection, and is serviced prior to leaving our warehouse. Simply follow the user-friendly operator manual and you will be chipping in no time at all.

220 LBS 26.5" DIAMETER FLYWHEEL - IDEAL WEIGHT

WoodMaxx MX-9900 wood chippers use a 26.5" dynamically balanced 220 pound flywheel to deliver the energy to quickly and easily chip all types of material. Competitors use a wide range of flywheel weights, but through thorough testing and experimentation, WoodMaxx has discovered that the 220 pound 26.5" flywheel is ideal for this size wood chipper.

MADE-IN-USA KNIVES

All WoodMaxx MX-series wood chippers are equipped with made in USA chipper knives and made in USA Holo-Krome class 12.9 knife bolts. Designed for extreme duty - there is no better material that can be used for superior performance and life than our through hardened, heat treated, high chromium, high carbon, A-8 tool steel knives.

FOUR DUAL EDGE REVERSIBLE CHIPPER KNIVES

The WoodMaxx MX-9900 wood chipper comes standard with four offset reversible dual edge knives installed. Thats right, four knives, and they are offset so that every 90 degrees of rotation the knife is taking a slightly different cut of the material. This is equivalent to using a serrated knife to cut bread instead of a straight knife. Ultimately, this feature allows for chipping large material without overworking your tractor. The reversible knives mean that you get twice the work out of one set of knives! These American made knives are securely bolted into a pocket that is milled in the flywheel using American made Holo-Krome bolts for added security, this design utilizing a new flywheel pocket design developed by WoodMaxx. This eliminates knife and bolt breakage that can be found on other dual edge knife systems. These knives are made right here in upstate New York of hardened, high carbon A-8 tool steel.

SELF-CONTAINED HYDROSTATIC INFEED DRIVE SYSTEM

With a patent pending design, the WoodMaxx MX-9900 wood chipper is complete with a self-contained hydrostatic pump that requires only a two quart oil reservoir tank to power the infeed motor. Unlike a standard hydraulic system, a hydrostatic drive system is so powerful that it is the same type of drives system that is used to drive bulldozers, trains, excavators, skid steers, and even ride on lawn mowers. This hydrostatic system uses standard 10W-40 motor oil and is so efficient, and generates so little heat, that it requires only a fraction of the reserve oil as a standard hydraulic drive system. This type of system also allows for complete speed control from 1 RPM to a full 75 ft./min. with full power through the entire speed range. The Hydrostatic drive system on the WoodMaxx MX-9900 is so unique to the industry that it is now Patent Pending. Hydraulic remotes are not required from your tractor. The hydraulic infeed motor is a standard size SAE 2-hole "A" mount. What does this mean to you? Down the road if there is a need to replace the motor, it can be found just about anywhere. Please note, you will need at least 25 horsepower at the PTO to operate this machine.

TACHOMETER/ HOUR METER

WoodMaxx MX-series wood chippers are now equipped with a convenient tachometer/ hour meter. The tachometer allows the operator to see the actual RPM of the flywheel to ensure that the chipping head is running at the optimal recommended speed. Proper flywheel speed is important to develop the inertia required to chip hard material and evacuate the chamber effectively. The hour meter is helpful to ensure that proper maintenance intervals are kept in accordance with WoodMaxx recommendations. This all-weather meter is water proof and weather tight.

USA "WHITE" BRAND HYDRAULIC MOTOR

WoodMaxx MX-series wood chippers are equipped with USA "White drive products" brand hydraulic infeed motors. White is renowned for their high-quality American engineered hydraulic motors.

FOLD UP INFEED BIN

The WoodMaxx MX-9900 PTO Wood chipper attachment is equipped with a fold up infeed bin. This feature allows the user to simply fold the infeed bin upward for storage or transport.


TRUE 9" x 9" INFEED OPENING

The WoodMaxx MX-9900 wood chipper offers a larger 9" x 9" infeed opening to easily accept those crooked branches. This is the largest infeed opening available of any PTO wood chipper in its class.

3/8" THICK FLYWHEEL HOUSING

The WoodMaxx MX-9900 PTO wood chipper is manufactured using heavy gauge 3/8" thick (American Standard A-36) structural steel plate for the flywheel housing. Since the flange bearings are mounted on the flywheel housing, this gives added strength and rigidity. Other chippers use only 1/4" steel.

EASY KNIFE ACCESS

WoodMaxx MX-series wood chipper knives can be changed easily by one person in as little as 10 minutes. The entire top of the blower housing opens like a clam shell. This allows for easy access to the flywheel and knife changing. Other chippers require you to reach into the infeed bin to hold the head of the bolt, while someone else turns the nut from the backside of the flywheel.

HEAVY DUTY 5/8" COGGED DRIVE V-BELTS

WoodMaxx MX-series wood chippers are equipped with five extreme duty 5/8" wide cogged drive V-belts that are made specifically for WoodMaxx. Cogged V-belts run cooler, and transfer more torque than plain smooth V-belts. Although the OEM belts are very high quality, if the need arises, the standard size BX belts allows you to purchase replacement v-belts at any auto parts store. Other chippers use 15mm belts - try to find those in the USA!

SAFETY AUTO FEED STOP BAR & INFEED ROLLER SPEED ADJUSTMENT

Safety is paramount on WoodMaxx wood chippers. Located on the top of the infeed bin, the MX-9900 utilizes an easy to activate hydrostatic auto-feed stop safety bar to disengage the infeed roller in case of an emergency, or to clear the infeed bin if necessary. Simply pull the bar forward to increase the speed, and push it forward to decrease or reverse the infeed speed and direction. The hydrostatic drive system is so refined that the infeed speed is fully adjustable from 0-75 ft./min.

HINGED INFEED HOPPER

All wood chippers will require some routine maintenance like adjusting the gap between the bed knife and the flywheel knives as they wear. This gap is essential to proper operation of the wood chipper. The infeed hopper on the WoodMaxx MX-9900 swings open to expose the bed knife. This feature allows the user to access the bed knife (anvil) by opening the hopper to expose the knives. Simply remove 2 bolts and the hopper will swing open like a door. This feature is exclusive to WoodMaxx, other chippers require the user to crawl into the infeed hopper to change the bed knife or adjust the gap between the bed knife and the flywheel knives.

STRENGTH IN DESIGN

WoodMaxx MX-9900 wood chippers are the perfect combination of size, weight, and features. Compact enough to easily move around, yet strong enough to get the tough jobs done. MX-series chippers are loaded with features typically found on much larger commercial machines that are much more expensive. The strength of our machines starts with using heavy formed (American standard A-36) structural steel plate, the strongest plate steel available. Each piece is laser cut, on a precision CO2 laser and meticulously welded by highly skilled American welders. WoodMaxx MX-series chipper exclusive structural design includes a 2" diameter main shaft that passes through the flywheel housing and is supported by two flange bearings. This feature, combined with the 2" shaft, allows the flywheel to run true and adds a great deal of strength. This design sets WoodMaxx chippers far apart from the competition, and it is a design feature you should not overlook when shopping for a chipper.

EXPERIENCE

WoodMaxx MX-9900 wood chippers are extremely robust, and can handle very heavy use. Designed and manufactured in upstate New York, each machine we offer is thoroughly tested on our 18 acre proving grounds before being offered to the public. With years of experience and thousands of machines in service today, we are confident that this machine can handle even the toughest projects that you have. Our machines are currently in service in several commercial applications, such as: the Army Corps of Engineers, college campuses, municipalities, The US National parks service, tree farms, golf courses, apartment complexes, and thousands of residences. WoodMaxx chippers are also represented around the globe, with machines as far away as Hawaii, and Alaska, as well as several countries including: Chile, Russia, Panama, Colombia, Poland, United Arab Emirates, Israel, west Africa, Greece, Norway, Iceland, Ecuador, Honduras, Ireland and of course Canada.

8" DIAMETER HARDENED STEEL COMMERCIAL STYLE
INFEED ROLLER
-

A WoodMaxx exclusive and patent pending design. Everyone knows what happens to the branches when they reach the flywheel knives of the wood chipper, but getting the material to pull into the wood chippers effectively and quickly is the trick. Many factors must be considered when designing an effective infeed roller system: the overall diameter, knife spacing, tooth angle, type of steel, hardness, down pressure and infeed speed. After countless hours of research and development on the infeed system, for the MX-8800 we have developed a large diameter (8") infeed roller. This exclusive design allows the chisel shaped teeth of the roller to grab and climb up and over the branches to easily bite in and effectively pull the material into the wood chipper flywheel at speeds up to 75 ft. /min. In short, the larger the roller, the easier it rolls over the material. The smaller the roller, the more likely it is to slip and spin on the branches. Similar to how the small wheels of a shopping cart stop when contacting a small stone in a parking lot. WoodMaxx MX-series auto-feed wood chippers utilize high carbon steel chisel tooth infeed rollers. This type of infeed roller is typically found on much larger, much more expensive commercial machines.

To prevent material like tree bark and leaves from impacting between the teeth of the infeed roller, we spaced the chisel teeth out. This spacing allows the complete down pressure of the high-tension gas springs to be focused on one chisel tooth at a time increasing total down pressure. Additionally, this spacing allows the roller to self-clean. These rollers, along with the high-tension gas springs aggressively bite into any type of material. After welding, these rollers are hardened to ensure that the teeth stay sharp for many years to come. The advantage of this type of roller is that is aggressively grabs any size limb with or without leaves up to 8". Long or short needle pine, as well as small, vine type material is no problem for the WoodMaxx MX-9900 wood chipper. Small branches, leaves, or vines won't wrap around the infeed roller as they would on other wood chippers. The exclusive advanced design of our infeed rollers is a feature that should not be overlooked when shopping for a wood chipper. Our infeed roller designs are so unique and effective that they are now patent pending.

EASY SWIVEL DISCHARGE CHUTE -

The WoodMaxx MX-9900 PTO wood chipper is equipped with a 360 degree swivel discharge chute. With easy two finger operation, we have incorporated a convenient handle that effortlessly allows you to swivel the discharge chute 360 degrees so that you can direct the chips into a trailer or the back of a pickup truck without having to move the entire machine. Simply push down on the handle and swing the chute, when you release the handle a spring-loaded pin drops down to lock the chute into position. No tools required.

AUTOMATIC BELT TENSIONER -

The hydrostatic pump belt tensioner is automatic on the MX-9900 wood chipper. This feature keeps consistent and correct pressure on the drive belt. If the drive belt is too tight then excessive bearing and or pump failure is likely. If it's too loose, the belt will slip. This feature eliminates the need to adjust the belt, ensures that proper tension is achieved, and increases the longevity of the pump and bearings. It also saves you the hassle of constant adjustment.

ADJUSTABLE BASE LEGS

You asked for it and we delivered! In 2012 WoodMaxx developed the first adjustable chipper base legs. This is a feature that we thought was important to incorporate into the MX-9900. The adjustable base legs will help to accommodate a larger variety of tractors. This innovation allows you to more easily meet the required PTO shaft angle of less than 15 degrees on larger tractors. Simply insert the adjustable legs, and then slide the pin into the hole for your required leg height. WoodMaxx chippers are able to accommodate tractors that have a PTO height from 18-30 inches in height.

WIDE FOOTPRINT SKID TYPE SUPPORT BASE

Because of the robust weight of the MX-9900 PTO wood chipper and to prevent the machine from sinking into the soft ground during operation, the new MX-9900 offers a wide footprint skid type support base. This skid shoe type base is angled upward on the end like a ski to prev ent it from digging into the soft ground during operation.

HIGH FLOW FLYWHEEL CHAMBER VENTILATION -

WoodMaxx MX-series wood chippers incorporate a series of precisely located ventilation holes in the flywheel chamber. This feature creates a strong vacuum that draws air into the flywheel chamber and in combination with the fan blades on the back of the flywheel forcefully ejects the wood chips out of the chamber. This keeps the discharge chute clear, and reduces the chances of a jam. The WoodMaxx patent pending hole pattern is specifically designed to bring the air into the chamber at the optimal volume and location. Other machines have tried to copy this feature, but have not achieved the same results!

JIC STANDARD HOSE FITTINGS

The WoodMaxx MX-9900 wood chipper utilizes JIC (joint industrial council) hose fittings that are rated for 5000 psi. For you this means that if you ever need to replace a hydraulic hose, that your local tractor supply or auto parts store can make hoses while you wait. JIC fittings are widely used in hydraulic fluid transfer, the military, and are typically very easy to come by. No trying to chase down an adapter because of mismatched threads.

MAIN SHAFT SUPPORTED BY TWO INDUSTRIAL FLANGE BEARINGS

The 2" main shaft on the MX-9900 PTO wood chipper passes through the flywheel housing and is supported by two industrial flange bearings. This feature, combined with the 2" shaft, allows the flywheel to run extremely true, while adding a great deal of strength. Competing machines use a 1-3/4" shaft in conjunction with two pillow block bearings, and the flywheel is cantilevered beyond these bearing. With this setup, there is a possibility of breaking a bearing housing if the machine jams.

INFEED ROLLER TENSION GAS SPRINGS

The WoodMaxx MX-series wood chipper utilizes high tension gas springs. These gas springs maintain the same tension throughout the entire range of motion. This feature also slows and dampens the downward motion of the infeed roller to prevent the infeed roller from slamming downward ultimately increasing the longevity of the components. These high-tension gas springs achieve 175 lbs. of downward force that allows the teeth of the infeed roller to dig into the branches and ensure a smooth entry into the chipper head.

WEIGHT

MX-9900... 1000lbs of American made steel!

RUST RESISTANT POWDER COAT FINISH

The WoodMaxx MX-9900 is finished with a powder coating that is baked on at 450 degrees. Powder coating finish is thicker and more durable than ordinary paint. Additionally, prior to powder coating the steel is prepared by shot blasting, (similar to sand blasting but with steel shot instead) which slightly scuffs and textures the steel to provide for a superior bonding surface. This is a more costly process but is superior to simply chemically cleaning the steel as most other will do.

CLEAR VINYL CHIP BAFFLE

Safety is paramount, therefore the WoodMaxx MX-9900 is equipped with a clear vinyl baffle feature that protects the user from chip blow-back, while allowing the user to see what is going on in the hopper.

SLEEK HYDRAULIC HOSE CONFIGURATION

The hydraulic hose configuration for the WoodMaxx MX-9900 requires only two streamlined hydraulic hoses. This is possible because of the patent pending upgraded hydrostatic drive system that eliminates many of the components and hoses of traditional open hydraulic systems. This feature makes future maintenance a breeze.

NYLON PROTECTIVE HYDRAULIC HOSE WRAP

Along with the simple two hose configuration, the MX-9900 includes the additional protection of nylon hydraulic hose wrap for long life. This hose wrap reduces chaffing and protects the hoses from abrasion and environmental damages.

PTO SHAFT

The WoodMaxx MX-9900 wood chipper comes with a standard imported PTO shaft. For an additional $150 you can upgrade to a premium quality USA made PTO shaft if purchasing with the chipper. When purchased separately, the USA PTO shaft will be $250. Have a quick hitch? The USA PTO shaft is compatible, or ask about our longer imported PTO shaft

Logger/Lumberman January 12, 2018
Reviewer: Deane Rapp from Elmendorf, TX United States  
I collect storm damaged/unwanted trees for lumber and have been in need of a rugged, well-built yet affordable chipper.  After much research and discussion with Wood Maxx folks I decided to purchase the MX-9900.  It arrived yesterday in excellent shape considering holiday and severe weather delays.  Today, I used this fantastic machine for several hours chipping slabs from the sawmill and branches from trees neighbors had me remove.  I am very impressed with its performance.  The native hickory and oak trees do not have straight branches, yet the MX-9900 did not stop feeding them to the knives and there were no snags in the hopper!  I could start a slab or branch and turn away to get the next piece to chip without worry and develop a steady work flow.  The clam-shell access to the knives is impressive as well as the straight forward design of the machine overall.  I refuse to burn and am very confident I will have many happy hours producing chips as an end product.

Heavy equipment business owner December 19, 2017
Reviewer: Anonymous Person from Pennsburg, PA United States  
My first impression was that the unit was smaller than I expected but during my walk around inspection and set up, it's exactly what it needs to be and was proven during operation. My tractor PTO is 37 hp and was more than adequate to handle anything that would fit in the unit. With that said the hydro-static feed is a very nice feature on this model to adjust the feed roller when you work with larger diameter wood. My hat is off to the Woodmaxx team for making an excellent chipper for tractors under 70 hp. Thank you!

Review of MX-9900 November 9, 2017
Reviewer: Mark Swanson from Laporte, IN United States  
I have 4 hours on the machine and so far it has performed as advertised.  I have 26 acres that has invasive honeysuckle and grapvine on it.  The machine has been keeping up with us without a problem.  Rountine maintenace looks like it should be no problem.  I have inspected the blades and they are still in excellent condition.

MX-9900 October 9, 2017
Reviewer: Norman from Watkinsville, GA United States  
The MX-9900 wood chipper was delivered as promised. Set up was easy and the instructions for cutting the PTO shaft was very straight forward.  I bought a PTO driven cement mixer from a different manufacture and the instructions for sizing the PTO shaft was very poor, I only had time to try the MX-9900 wood chipper for a short time, but so far I'm pleased with the construction and attention to detail. Seems to be a robust machine. I will follow up with a longer review after I use it for a longer period of time.

More than pleased / See addendum April 11, 2017
Reviewer: Tim Lucas / Richmond VA from Manakin Sabot, VA United States  
I've used the chipper now for 3 hours.  It continues to perform exactly as I had hoped.  No problem with large oak branches or 15 ft pine branches.  I cut a lot of trees each year and the biggest problem has always been the transport and disposal of the limbs.  Now I just leave them in a finely chipped layer in the woods and just haul off the logs.  EXTREMELY pleased with this purchase.  So confident in this company I've already placed an order for a pto snow blower.11/17  Have now used the chipper about 8 hours/5 different times.  Works perfectly every time.  Would highly recommend this product and company.

Update:  I now have 26 hours on this machine.  It has worked flawlessly the entire time.  Couldn't be happier.
