DRIVE CHAIN
The drive chain is tightened by tightening the 1/2"
tensioner bolt drawing the two tensioner brackets
together. Tighten this bolt to a max of 5 ft. lbs., then
lock the nut using another jam nut.
Clean out any dirt accumulated in the chain case.
Use a brush to spread an even coat of lubrication
over the entire length of chain.
IMPORTANT: After the first three hours of
operation check the tightness of the drive chain and
re-tighten if necessary. Afterwards periodically
check for proper tightness. When tightening the
Split Tapered hub to the drum sprocket, torque the
3/8" bolts to 29 ft.-lbs (39 Nm).
WINDROWER TEETH
Teeth are made from high strength abrasion resistant 450BHN steel, for superior wear resistance. Additional
hard surfacing is not necessary. However, if it is desired, CS170 hard surfacing electrodes are recommended.
TIRES
Periodically check tire pressure. Tires should be inflated to 45 PSI. Higher pressures may cause excessive
bouncing over rough ground. Lower pressures may cause excessive wear.
To remove tires for repair or replacement, securely block the frame. Relieve hydraulic pressure. Shut off power
unit and apply parking brake and disengage PTO.
AVOID PERSONAL INJURY. DO NOT work under windrower without support blocks to
keep the frame from falling.
