least annually thereafter, of the proper operation, precautions, and work
hazards which exist in the operation of the machine in accordance with
OSHA regulations.
Safety Is No Accident
The following safety instructions, combined with common sense, will
save your equipment from needless damage and the operator from

BOLT TORQUE
Important: Over-tightening hardware can cause just as much damage as
under-tightening. Tightening hardware beyond the recommended range
can reduce its shock load capacity.
All hardware on the 5500 Cover Crop Devastator is either Grade 5 or
Grade 8, unless otherwise noted. Grade 5 cap screws are marked with
three radial lines on the head. Grade 8 cap screws are marked with six
radial lines on the head. If hardware must be replaced, be sure to replace it
with hardware of equal size, strength and thread type. Refer to the torque
values chart when tightening hardware.
The chart below is a guide for proper torque. Use it unless a specified
torque is called out elsewhere in the manual.
Torque is the force applied to the end of the handle or cheater bar, times
the length of the handle or bar.
Use a torque wrench wherever possible
The following table shows torque in ft.-lbs. for coarse thread hardware.

½” x 2-1/2” bolts and locknuts.
IMPORTANT: The spacer must be installed between the roller and the bearing.
The notches of the bearing housing must face the mounting plate. The
extended race on the bearing will face toward from the roller.
BEARING REPLACEMENT
Put the bearing housing in a vice, use a pry bar to turn the bearing in the housing parallel with the slots, remove the old
bearing, apply anti-seize lubricant to the interior of the bearing housing, insert the new bearing in the slots, & use a pry bar to
move back to position. Wobble the bearing around to help work the lubricant into the outer race of the bearing.
