POW-R-TORQ™️️ is a trademarked and patented infeed system. This system is a combination of our patented hydrostatic pump motor, specially designed infeed roller, nitrogen filled gas springs, automatic belt tension device and American made A8 tool steel knives. Combined, these features create the most powerful, efficient and speed variable infeed system available on ANY wood chipper on the market today.

Hydrostatic drive systems have several differences and benefits over traditional hydraulic drive systems. Hydrostatic pumps exhibit variable displacement without the need for external devices such as flow control and flow diverter (proportioning) valves. This reduces the number of fittings, hoses, and amount of oil needed. Unlike hydraulic systems requiring several gallons of oil, our hydrostatic system only needs 2 quarts of motor oil (Why can’t I use synthetic oil in my chipper?  Click here to find out)  Hydrostatic technology has been around for decades and is used in some of the highest demanding and harshest mobile applications such bulldozers, trains, excavators, skid steers, and even ride on lawn mowers. Hydrostatic systems are very efficient, generate minimal heat, and are extremely precise, allowing for smooth infeed speed control from 1 ft./min to a full 75 ft./min. with full power through the entire speed range. Take a look below for more information on each of these key POW-R-TORQ™️️ features or watch a short video here.

The WoodMaxx MX-8600 requires a tractor with a category 1 or 2 three-point hitch and at least 15 HP at the PTO. Chipping capacity is directly related to horsepower and torque, therefore with 15 HP you can expect to chip 4″ hard wood and 6″ soft wood. With 50+ HP you can expect to chip any material up to 6″ in diameter with no trouble.

A WoodMaxx patented 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, we have developed a large diameter (8″) octagonal shaped infeed roller. This innovative 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.
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. The advantage of this type of roller is that it 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-8600 wood chipper. Small branches, leaves, or vines won’t wrap around the infeed roller as they would on other chippers.

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 force 175 lbs. of downward pressure that allows the teeth of the infeed roller to dig into the branches and ensure a smooth entry into the chipper head.

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.

The WoodMaxx MX-8600 wood chipper is equipped with a USA-made hydraulic infeed motor. This high quality 200cc orbital motor offers high load bearing capacity, giving it the ability to withstand thousands of hours of rotational resistance, that comes with drawing large, dense material into the infeed bin. It also offers extremely high torque for maximum pulling efficiency.

The WoodMaxx MX-8600 PTO wood chipper is manufactured using heavy gauge 1/4″ 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.

Unlike the belt-driven MX-8800 and MX-9900, the MX-8600 is a PTO direct drive-system. In other words, the shear bolt protected PTO shaft will attach directly from your tractor to the chipper flywheel rather than running through a series of belts and pulleys. This eliminates the need for replacement drive belts. Even though rotational speed is less, it is made up for in torque gained. Having higher torque allows for greater horsepower at lower rpms. Low end torque is important for better power at slower speeds making the MX-8600 more than capable of handling the proposed material size.

Safety is paramount on WoodMaxx wood chippers. Located on the top of the infeed bin, the MX-8600 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 in-feed speed and direction. The hydrostatic drive system is so refined that the infeed speed is fully adjustable from 0-75 ft./min.

The WoodMaxx MX-8600 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.

The hydrostatic pump belt tensioner is automatic on the MX-8600 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.

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!

The WoodMaxx MX-8600 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.

Safety is paramount, therefore the WoodMaxx MX-8600 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.

WoodMaxx MX-8600 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 innovative structural design includes a 1 3/4″ diameter main shaft that passes through the flywheel housing and is supported by two flange bearings. This feature, combined with the 1 3/4″ shaft, allows the flywheel to run true and adds a great deal of strength.
