• Your chipper will need to be set up prior to installation. It arrives in a steel crate that can 

be dismantled in minutes. 

• The infeed bin and discharge chute are shipped with the unit and are located in the 

bottom of the steel crate.

• Visually inspect the infeed bin, and the fly wheel before attaching to tractor, and applying 

power to ensure that nothing is in the chipper head. If the chip deflector or any of the 

guards have been removed for shipping, be sure to replace them properly before use.

• The PTO (Driveline) is also shipped with the unit and is located in the bottom of the steel 

crate.

• When mounting, keep the chipper as close to the tractor as possible.
• 

IMPORTANT

 - Make sure that the PTO shaft is sized properly. See 

PTO Shaft Sizing 

Instructions 

on page 20 of this manual.

• While in use, keep the PTO shaft as straight as possible. Your PTO shaft will be more 

efficient and will have a longer life if it is as close to level as possible.  

No more than 25° degrees from level is acceptable.

• Do not operate the chipper without the chip deflectors, and or drive belt cover properly in 

place.

• Read and understand all assembly instructions prior to assembly.
