NSK BRAND SHAFT BEARINGS

NSK is a leading bearing and motion control manufacturing company founded in Tokyo, Japan in 1916. Today NSK has several plants around the world including England, Germany, USA and Switzerland and by far one the best quality bearings available on the market today. Although these bearings are very costly, we feel that in an application with high load and dynamic forces such as a flail mower that such high quality bearings are required. These bearings are noticeably smoother, quieter, and cooler running than any competitor and far superior to any no-name brand. Some inferior bearings contain plastic interior ball cages that are susceptible to breakage from shock loads. Poor material and tolerances generate excessive heat that translates into premature bearing failure and even belt wear as the heat travel to the pulleys and the belts. All bearings are not created equal, and this is a feature that should not be overlooked when shopping for a flail mower.

OVERALL WIDTH

79.5"

CUTTING WIDTH

74"

WEIGHT

804 LBS. (mower weight only) PTO shaft weighs an additional 39 lbs.

HP REQUIREMENTS

30-65 PTO horse power

CUTTING HEIGHT

3/4" - 2-3/4" Adjustable to meet various height requirements

DECK PLATE MATERIAL THICKNESS

4 Gauge .25" structural Q235 roll formed steel for durability.

SIDE PLATE THICKNESS

1/4" .250" Structural Q235 roll formed steel for durability.

BLADE TYPE

Duckfoot or reversible Y-blades. Our duckfoot blades are 40cr, alloy structural steel. (American standard, AISI/SAE/ASTM steel no: 5140) and forged to a tapered wedge shape to avoid material buildup on the blades. Each blade weighs 1.85 lb. (cast steel is much more durable than cast iron) competitors use flat face blades. Side by side comparison of WoodMaxx exclusive duckfoot design: The reversible Y-blades are made from .33" 60si2mn, spring steel, (American standard: A29m) formed, heat treated, and quenched in oil and weigh 1.75 lb. each. Use the duckfoot blades for clearing saplings (1" diameter or less), and the Y-blades for grasses.

NUMBER OF BLADES

22 Duck-foot or 44 Y- blades w/ 22 ctr blades between the Y (WoodMaxx exclusive)

PRECISION BLADE OVERLAP

The blades are staggered precisely with no gap in the mowing area. Blade overlap is important to achieve an even cutting result.

HINGED REAR GATE

This allows for easy inspection, cleaning, blade changing, and maintenance of your machine. The rear gate can also be left open for easier discharge in heavy conditions, or you can close the gate to greater mulching.

ROTOR ROTATION - REVERSE

The rotor spins in the opposite direction as the wheels of the tractor when traveling forward. This allows the blades to shear the material as it is folded forward by the mowers. The material is then thrown up and over the rotor.

ROTOR TUBE DIAMETER

4.25"- Heavy duty 5/16" wall tubing for long life.

BALANCED ROTOR TUBE

The rotor tube is balance to reduce vibration and ensures that the mower runs smooth, and reduces wear on the bearings.

BALANCED CAST IRON PULLEYS

The V-belt pulleys are heavy duty cast iron and balance to eliminate vibration, and run smooth.

ROTOR SWING DIAMETER - 13.5"

Large swing so that the blades build required inertia.

ROTOR SHAFT SPEED

2160 RPM

BLADE SPEED

128 ft./sec - High tip speed = efficiency to cleanly cut material

HITCH TYPE

Category 1 standard 3 point or category 1 quick hitch - will attach to any cat 1- 3 point hitch and will also work with cat 1 quick hitch (except John Deere I-Match)

HYDRAULIC SIDE-SHIFT OFFSET

Shifted left (36"L/43"R), shifted right (22.5"L/57"R). This feature allows for variable offset from the center to the right of the tractor. This feature is helpful for mowing around fences, buildings, walkways, etc. Total offset can reach 18". NOTE: Requires rear hydraulic remotes on tractor. We cannot supply these if your tractor does not already have them, they must be dealer or factory installed. (Hose ends that connect to the tractor are fitted with 1/2-14 NPTF threads, you will have to provide the corresponding fittings to complete the connection to your tractor.)

DRIVE BELTS

3 Total B-series USA gates "truflex" - we use only USA made gates belts on our flail mowers for long life. (Easy to find SAE standard belt size BX39)

DRIVE BELT TENSIONER

Solid state automatic - this feature automatically adjust the belt tension so you don't have to worry about slippage or overworking the belts. This feature greatly increases the belt life.

PTO SPEED

540 ONLY

GEARBOX RATING

Up to 55 hp. heavy duty proven oil bath gearbox for long life.

GEARBOX TYPE

Cast iron 540 RPM with internal over-running clutch - when the PTO shaft is disengaged the built in over running clutch allows the PTO shaft to stop turning while the gearbox and rotor shaft slow down gradually. This is an important feature, without it, the gearbox will slam to a halt when the PTO is disengaged, causing stress to the gearbox and your tractor. This feature should not be overlooked when shopping for a mower.

REPLACEABLE SKID SHOES

The skid shoes reduce gouging are bolt on so you can adjust or replace them easily when the time comes.

DRIVE-LINE / PTO SHAFT

1-3/8" 6 spline w/slip clutch.

GREASEABLE SHIELDED BEARINGS

Accessible greasable bearings for easy maintenance.

REAR HEIGHT ADJUSTING ROLLER DIAMETER

5.25" With tapered ends - this roller contacts the ground to ensure even cutting height. The ends of this roller are rounded to eliminate gouging when turning corners. A scraper bar ensures that mud and debris buildup is cleaned off as you go.

POWDER COAT FINISH

The rust resistant baked on powder coat finish is more durable than conventional paint to keep your machine looking good for years.

WARRANTY - 2 YEARS

A robust machine with an equally robust warranty.
