RR420 8″ PTO Wood Chipper
8" x 8" opening for tractors ranging from 35 to 100 HP.
The Range Road RR420 8” (20cm) PTO drive wood chipper was designed for tractors with 35 to 100+ HP. This heavy-duty wood chipper contains an auto hydraulic infeed system and 8″ x 8″ (20 cm x 20 cm) opening making it easy to feed branches of all shapes and sizes. The discharge chute was designed to rotate 360 degrees, making it easy to direct wood chips in any direction. By adjusting the rotating deflector at the end of the chute, you can choose to discharge chips for maximum distance or deflect them directly down to the ground or into a trailer.
Range Road is pleased to offer our newly designed and exclusive 8” (20cm) PTO drive wood chipper with auto hydraulic feed. The RR420 was designed to offer acreage owners an economical and well engineered wood chipper. This is a serious wood chipper, with a huge 8” (20cm) chipping capacity. It was built to be the best valued wood chipper in its class. From the powder coated structure, to its industrial pillow block / flange mount bearings and 4 “V” belt drive system, this wood chipper will exceed your expectations.
The RR420 operates on tractors with 30-100 HP. It utilizes a large 23” x 27” (59 cm x 69 cm) infeed hopper opening that tapers down to an 8” x 8” (20 cm x 20 cm) opening where the 8.25” (21cm) 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 8” (20cm) diameter can be fed through the RR420. To chip full 8” (20cm) diameter logs, tractors with over 60 HP are required.
Hydraulic Infeed System
Branches are pulled into the RR420 via the large 8.25” (21cm) 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 direct drive from the lower shaft, meaning there is no need to worry about wearing or loose drive belts. 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 24” (61cm) diameter, 1” (25mm) thick, and 120 lb / 54 kg solid steel flywheel runs on a 2” (50mm) 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 1,100 RPM ensuring maximum airflow.
Drive Belt System
The drive belt system is encased by a ¼” (6mm) thick steel guard which can quickly be rotated forward to access the drive system. Simply pull the pin at the top and the guard folds forward, providing quick and complete access to the entire drive system. The PTO shaft (included with chipper) connects from your tractor to the chippers lower 2” (50mm) shaft. Four heavy duty cogged BX series drive belts run up to the flywheel main shaft. These belts are standard off the shelf replacement parts. They are automatically kept in proper tension via the self tensioning system. This system dramatically increases belt life, reduces belt slippage and saves the user from manually adjusting for belt tension. Changing belts are also made easy as the tensioning system can easily be pulled back out of the way allowing the belts to be changed out quickly.
The RR420 chipper utilizes four high quality hardened steel reversible chipper blades. These blades are 90 degrees apart and are offset from one another. They can be flipped to take advantage of having two cutting edges on one blade. Each blade is held onto the flywheel with two countersunk M10 bolts and locking nuts. Changing blades can be made 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 RR420 wood chipper has a large 23” x 27” (59 cm x 69 cm) opening, making it easy to feed branches with multiple limbs effortlessly. The infeed chute can also be folded up which decreases the footprint of the chipper during storage or transport.
The opening in the flywheel housing is a large 8” x 8” (20cm x 20cm) square making it quite easy to accept branches with several limbs. This reduces the need to trim your branches down before feeding them into the chipper.
Adjustable Chipper Base
The RR420 chipper has a heavy duty chipper base made of 1/2″ (12mm) thick laser cut steel plates. This base can be adjusted so that the PTO shaft sits at 15-5/8″ to 21-5/8″ (40 cm to 55 cm) off the ground to suit various tractor sizes. Simply hook the chipper up to your tractor and lift it up so it is suspended in the air. The four bolts that hold the base to the chipper housing can be removed and the base can be raised or lowered to suit your tractor configuration.
The discharge chute was designed to rotate 360 degrees by simply loosening the eye bolt and spinning it by hand 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 73” (1.9m) 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.
Included with the RR420 chipper is the PTO shaft complete with a shear pin.
The RR420 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 20L (5 gallons) of AW32 hydraulic oil in the tank which is not included. Lastly, attach the PTO shaft that comes included and trim it to length for your tractor as per the manual if required.
The RR420 was designed for property owners, but built like a commercial wood chipper. It weighs in at 1,050 lbs (476kgs).
The RR420 is covered by a full 2 year warranty against any manufacturing defects. Wearing parts such as belts, bearings and blades are not covered under our warranty.
