Section 4: Maintenance & Lubrication
Maintenance
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.
!
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.
!
WARNING
To avoid serious injury or death:
Always shut tractor down using "Tractor Shutdown
•
Procedure" provided in this manual before dismounting
tractor.
Do not alter implement or replace parts on the implement
•
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.
1. After using your Overseeder for several hours, check
all bolts to be sure they are tight.
2. Lubricate areas noted in the "Lubrication" section.
3. Adjust idlers to remove excess slack from chains.
Clean and use chain lube on all roller chains as
needed.

obtaining new labels from your Land Pride dealer.
