Proper servicing and adjustment is the key to the long life
of any implement. With careful and systematic
inspection, you can avoid costly maintenance, time, and
repair.
After using your Powered Rake for several hours, check
all bolts to be sure they are tight. Replace any worn,
damaged, or illegible safety labels by obtaining new
labels from your Land pride dealer.

BEFORE any maintenance is performed, lower the Powered
Rake to the ground, stop skid steer engine, and remove key.
DO NOT attempt to make maintenance adjustments while skid
steer is running.
