The Woodland Mills WC46 PTO drive wood chipper was specifically designed for sub-compact tractors with 15-30HP at the PTO. Featuring a hydraulic infeed system, the WC46 is capable of chipping up to 4” (10cm) diameter material. The WC46 is a good fit for customers with sub compact tractors that feature the following: 1) Rear PTO that spins at 540RPM 2) 15-30HP at the PTO 3) Ability to lift 550lbs (250kgs) at the 3 point hitch system.


The WC46 operates on tractors with 15-30 HP at the PTO. It utilizes a large 19” x 18.5” (48cm x 47cm) infeed hopper opening that tapers down to a 4” x 6” (10 cm x 15 cm) opening where the 5.25” (13cm) diameter hydraulically driven infeed roller grabs the branches and feeds them through the chipper. Branches as small as ¼”(6mm) diameter and as large as 4” (10 cm) diameter can be fed through the WC46. To chip full 4” (10cm) diameter logs at full infeed speed, tractors with over 20 HP at the PTO is required.

Hydraulic Infeed System

Branches are pulled into the WC46 via the 5.25” (13cm) diameter infeed roller. The roller is hydraulically driven via the chippers self contained hydraulic system. The roller is adjustable in direction and speed making it easy to feed branches of all shapes and sizes. The hydraulic pump is belt driven from the main flywheel shaft. The roller down pressure may be adjusted via the two large springs ensuring it grabs branches and easily pulls them in, eliminating the need for manual feeding.


The dynamically balanced 18” (46cm) diameter, 3/4” (2cm) thick solid steel flywheel runs on a 2” (5cm) diameter shaft and is supported by 2 industrial and greaseable flanged bearings. It features four CNC machined pockets to hold the reversible blades. The flywheel features four large fan blade paddles that spin at over 540 RPM.

Flywheel Locking Pin

The WC46 wood chipper features a flywheel locking pin for convenient and safe blade changes or flywheel maintenance. The pin simply fits into a series of holes that are positioned so that every blade can be easily accessed with tools while reversing or changing them. No more unsafe blade changes with the Woodland Mills flywheel locking pin.

Chipper Blades

The WC46 chipper utilizes four high quality hardened steel reversible chipper blades. These blades are 90 degrees apart. They can be flipped to take advantage of having two cutting edges on one blade. Each blade is held onto the flywheel with four countersunk M10 bolts and locking nuts. Changing blades can be done very quickly thanks to the clamshell flywheel housing design. Simply undo one bolt and the upper flywheel housing rotates open, providing full access to the flywheel and chipper blades.

Folding Infeed Chute

The infeed chute on the WC46 wood chipper has a 19” x 18.5” (48cm x 47cm) opening to feed branches into. The infeed chute can also be folded up which decreases the footprint of the chipper during storage or transport.

Infeed Opening

The discharge chute was designed to rotate 360 degrees by simply rotating it with the two handles to the desired angle. This makes it possible to direct the wood chips in any direction regardless of the location of the chipper. The end of the chute stands at 66” (1.7m) off of the ground, making it quite easy to direct the wood chips into the back of a truck or trailer if desired. Located at the end of the discharge chute is a rotating deflector, which allows further control of the location of the wood chips. Simply point it straight for maximum distance or angled down to deflect the chips directly down to the ground or into a trailer.

PTO Shaft

Included with the WC46 chipper is the PTO shaft complete with a shear pin.


The WC46 chipper will arrive in a steel crate and can be up and running in as little as one hour. The infeed chute and discharge chute have been removed during shipping to eliminate the possibility of damage. The chipper will require 4.5 gallons (17L) of ISO 46 hydraulic oil in the tank, which is not included, but can be purchased at most farm or hardware stores. Lastly, attach the PTO shaft that comes included and trim it to length for your tractor as per the manual if required.


The WC46 was designed for property owners, but built like a commercial wood chipper. It weighs in at 550 lbs (250kgs).
