Section 4: Maintenance & Lubrication
General Maintenance Information
Proper servicing and adjustments are key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly downtime and repair.
Check all bolts and pins after using the plow for several
hours and on a regular basis thereafter to ensure they are
tight and secured. Replace worn, damaged, or illegible
safety labels with new labels from your Land Pride dealer.

DANGER
To avoid serious injury or death:
Always secure equipment with solid, non-concrete supports
before working under it. Never go under equipment supported
by concrete blocks or hydraulics. Concrete can break,
hydraulic lines can burst, and/or hydraulic controls can be
actuated even when power to hydraulics is off.
!

•
Allow only persons to perform maintenance on this
implement who have been properly trained in its safe
operation.
•
Always shut tractor down using "Tractor Shutdown
Procedure" provided in this manual before servicing,
adjusting, cleaning, or maintaining this implement.
Perform scheduled maintenance. Check for loose hardware,
•
missing parts, broken parts, structural cracks, and excessive
wear. Make repairs before putting implement back into
service. Serious breakdowns can result in injury or death.
•

with other brands. Other brands may not fit properly or meet
OEM (Original Equipment Manufacturer) specifications.
They can weaken the integrity and impair the safety,
function, performance, and life of the implement. Replace
parts only with genuine OEM parts.
