BLADE CARRIER REMOVAL
Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade
carrier is loosened. Use a suitable 2 jaw gear puller to pull carrier off tapered gearbox shaft. If gear puller is not
available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite end of
bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process.
BLADE CARRIER INSTALLATION
Clean the splines on both the blade carrier and output shaft. Position carrier on the gearbox output shaft and
install special washer nut.
Tighten nut holding blade carrier to minimum 350 ft. pounds, strike the carrier near the hub several times with a
heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent damage to the nut and threads.
Retighten the nut to 350 ft. pounds. Install cotter pin and spread.
Always recheck gearbox output shaft slotted blade carrier retaining nut torque after a few
hours operation.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from
falling.
STORAGE
Your rotary cutter represents an investment from which you should get the greatest possible benefit. Therefore,
when the season is over, the cutter should be thoroughly checked and prepared for storage so that a minimum
amount of work will be required to put it back into operation for the next season. The following are suggested
storage procedures:
1. Thoroughly clean the cutter.
2. Lubricate the cutter as covered in Maintenance Section.
3. Tighten all bolts and pins to the recommended torque.
4. Check the cutter for worn or damaged parts. Make replacements immediately.
5. Store the cutter in a clean, dry place with the cutter housing resting on blocks.
6. Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the cutter.
