Top 10 Frequently Asked Questions

1. What is the difference between a WM-8H and a WM-8M PTO wood chipper?

The WM-8M and the WM-8H are basically the same machine. They’re made out of the same materials, have the same capacity, the same blades and the same 6.25″ chiseled infeed roller, which is what drives each of the systems in these chippers, and makes the design special. The only difference is the infeed system.

The WM-8M uses a belt-driven gearbox with a clutch and a driveshaft outfitted with articulating u-joints to propel the in-feed roller. With the cable disconnect system, you have a 0steady forward material draw of 58 feet per minute and stop. This system is capable of handling 8“softwood chipping material if you have 50+ PTO Horsepower, but really shines if only you ‘re chipping 4“and below all the time.

The WM-8H uses a fixed gear pump to provide fluid to dual drive motors to draw the material in. In line with these drive components are two valves to regulate the speed and flow of the hydraulic fluid, altering the way the feed rollers operate. With this system, you also have the benefit of the reverse function to draw the material back out. This makes it much easier to accommodate the larger material. WoodMaxx recommends this chipper if you’re chipping in the 6“range a majority of the time.

2. What is the difference between an MX-8800 and a WM-8H/WM-8M PTO wood chipper.

The MX-8800 was designed to be the U.S.A. manufactured version of the WM-8H but with a better design. The in-feed system is a Hydrostatic system that uses fewer components than the hydraulic system. In this system, we have the tank to supply the pump, the hydrostatic pump, feed roller motor and 4 hoses. There are no extra valves or hoses require for this system to operate as the fluid is fully regulated inside of the pump. This equates to a much more efficient operation and less fluid required to operate (2 Quarts of 10w-40 motor oil versus the WM-8H’s 7 Gallon Hydraulic Fluid). On the flywheel housing, the clam-shell design offers easier access to the flywheel knives than the WM-8H/WM-8M chippers by simply removing one bolt and hinging the entire top half of the flywheel housing. This helps to cut down on maintenance time. The MX-series chippers come Category 1 quick hitch ready. There are multiple pin holes to allow a standard category one hitch setup or Category 1 quick hitch. The supplied Premium PTO Shaft comes in at 29“of overall length which makes for easier quick hitch connectivity or can be sized down for a standard Category 1 hook-up. Also, the weight of theMX-8800 is around 850lbs which is closer to the WM-8M, but less than the WM-8H at 990lbs.

8. What is the difference between Y-blades and Hammer blades?

blade design is made out of a cast material and has a slightly heavier swing for 1“saplings or less.

9. Where do I go to get my knives sharpened?

10. What type of oil should I put in my implement?

Why ?

What sets our 3pt wood chipper apart from all others is the attention that we pay to every single detail. From each of the bolts to our through hardened blades, there is not one component on these machines that was not built to last. For those that would like the confidence that they are buying the absolute best product possible, we ensure that all of our blades are only made in the USA and are made of high chromium, high carbon, and heat treated.

In addition to offering a rugged wood chipper to each of our customers, we also believe that it is our responsibility to include all of the features that will make the clearing out of branches, dead trees, shrubbery and other debris as easy as possible. This includes unique double infeed rollers that will require the operator to spend less of their own time and energy on every job. These spring infeed rollers will aggressively grab limbs that are up to 8-1/2 in size, applying constant pressure as it pulls them in.

For those that would finally like a reliable way to change the size of their chips, every WoodMaxx 3pt wood chipper also comes with variable speed options. While many other companies rely on adjustable blades in order to change the sizing, this can quickly damage the blades and other internal components of the tool. The most efficient and effective way to regulate the sizing is with an adjustable speed that will keep blades in working condition for years on end.
