MAINTENANCE
BLADE CARRIER INSTALLATION
Clean the bore on blade carrier and surface of output shaft. Position carrier on the gearbox output shaft and
install washer and slotted nut.
Tighten nut holding blade carrier to minimum 400 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 400 ft. pounds. Install cotter pin and spread.
Always recheck spindle output shaft slotted blade carrier retaining nut torque after a few
hours operation.
Operating the mower with a loose blade pan or holder can damage the taper connection on
the gearbox output shaft. To ensure proper seating between the blade holder and output
shaft, check and tighten the retaining nut after the first day of operation. Recheck the blade
carrier attachment each morning before operating. Grasp the carrier firmly with both hands
and try to push and pull the carrier with one hand while pulling and pushing with the other
hand to try to rock or oscillate the blade carrier. If the carrier is loose, retighten the retaining
nut before operating the mower.
STORAGE
Your mower represents an investment from which you should get the greatest possible benefit. Therefore,
when the season is over, the mower 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 mower.
2. Lubricate the cutter as covered in Maintenance Section.
3. Tighten all bolts and pins to the recommended torque.
4. Check the mower for worn or damaged parts. Make replacements immediately.
5. Store the mower in a clean, dry place with the mower head resting on blocks.
6. Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the mower.
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death.
