2 Section ASSEMBLY IMPORTANT WARNING If any bolts or nuts are dropped in the machine, be sure to remove them before starting the machine. Before inspecting or servicing any part of this machine, disengage PTO, shut off tractor engine, and make sure all moving and/or rotating parts have come to a complete stop. 2.1 ATTACH CHIPPER CHUTE and extension tray WARNING Do not operate this unit without the chipper chute correctly installed. Rotating cutting blades can cause serious personal injury. 2.1.
ASSEMBLY 2.1 ATTACH CHIPPER CHUTE (cont.) 2.1.3 attaching Extension tray (71854S, 72854) 1. Slide the chute extension tray over the chipper chute. Make sure that you position the lip on the extension tray behind the lip on the chipper chute. Align the five bolt holes in the chute extension tray with the bolt holes in the hinge. IMPORTANT See Section 4.1 for hydrostatic pump start-up procedure. 2.
ASSEMBLY 2.4 ATTACH DISCHARGE TUBE (cont.) 2.6 CONNECT PTO SHAFT 1. Attach chipper to tractor with 3 point hitch. Adjust the machine up and down to find the shortest distance between the chipper rotor shaft and tractor PTO. Stop the machine in the shortest position. 2. Pull the driveline into two pieces. Connect one end to the tractor PTO and the other end to the chipper rotor shaft. Line up the two halves parallel to each other.
3 Section CONTROLS & OPERATION 3.1 controls 1. Three point hitch connection: Mounts chipper to tractor 3 pt. hitch. 5. Leg stands: Never move machine unless the 3 point is lifted and legs clear the ground. 2. PTO shaft: Connects chipper to tractor PTO shaft. Avoid driveline angles over 20 degrees on PTO shaft when unit is in use. NOTE: Minimum and maximum telescoping on the PTO shaft is 20.08" to 26.93". This will leave a 6.85" overlap. 6.
CONTROLS AND OPERATION 3.2 operation 3.2.1 STARTING 1. Place tractor transmission in park or neutral and set parking brake. Connect 3 point mounts between the chipper and tractor. Secure connections with snap pins. Adjust 3 point top link so that the chipper sits level. 2. Connect PTO shaft to tractor. Make sure you are using the correct RPM machine. Do not operate machine at speeds different than specified on shield. 3.
4 Section HYDRAULIC FEED 4.1 hydraulic feed instructions CAUTION Handle pressurized hydraulic fluid carefully. Escaping pressurized hydraulic fluid can have sufficient force to penetrate your skin causing serious injury. This fluid may also be hot enough to burn. Serious infection or reactions can develop if proper medical treatment is not administered immediately. 7. A motor fitting may have to be loosened and oil-bled to remove air from the system (use same procedures as steps 3-5). 8.
HYDRAULIC FEED 4.3 HYDRAULIC FEED MAINTENANCE NOTE: Check the reservoir daily for proper fluid level, the presence of water (noted by a cloudy to milky appearance, or free water in bottom of reservoir), and rancid fluid odor (excessive heat). The hydrostatic pump normally does not require regular fluid changes. The system filter should be changed at either 250 hour or annual intervals, whichever comes first.
5 ELECTRONIC FEED SENSOR optional kit for hydraulic feeds standard on 76854 Section 2. Push the “S” button once with the desired RPM setting displayed to save. Do not choose a setting equal to or below zero. 5.1 installing the sensor note Refer to the pictures and illustration on the next page when following these steps. 1. Remove the drive belt guard. 2. On the collar located on the rotor shaft behind the chipper drive pulley, replace the set screw with the 5/16" x 1-1/2" bolt. 3.

6 SERVICE & MAINTENANCE Section Chipping Blade Sharpening Tips WARNING Before inspecting or servicing any part of the machine, disengage PTO and make sure all moving parts have come to a complete stop. The chipping blades are sharp! Use care when working on machine to avoid injury. WARNING The rotor assembly has a lock mechanism. When working on the rotor assembly, use the lock mechanism at all times. Remove plastic bearing cover under the chipper chute.
SERVICE & MAINTENANCE 6.2 SETTING BLADE CLEARANCE (cont.) If the chipping anvil edge is damaged or worn unevenly, remove the three bolts holding the anvil and use one of the other three edges. Adjust for correct measurement. 6.3 ADJUSTING/REPLACING DRIVE BELT Check the condition of the drive belt annually or after every 30 hours of operating, whichever comes first. If the belt is cracked, frayed, or worn, replace it. To replace or adjust drive belt, proceed as follows: 1.
SERVICE & MAINTENANCE 6.7 service and maintenance schedule IMPORTANT WARNING Every 8 hours of operation, check the bolts on the following for correct torque: • Hydraulic feed roller bearing • Hydraulic motor mounting • Chipper rotor bearing • Rotor paddles • Chipper anvil Before inspecting or repairing any part of the machine, shut off the engine and make sure all moving parts have come to a complete stop.
