Maintenance
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.
!
CAUTION
BEFORE any maintenance is performed, lower the Powered
Rake to the ground, stop tractor engine, and remove ignition
key. DO NOT attempt to make maintenance adjustments while
tractor is running.
Drive Chain Maintenance
The operator should check chain tightness after initial
run in and periodically thereafter to make sure that the
drive chain is tensioned correctly. If adjustment is
needed refer to “Drive Chain Adjustment” on page 15.
