Hydraulic Lift System - Landoll 5210 Operator's Manual

OPERATION AND MAINTENANCE

Hydraulic Lift System

The Grain Drill is equipped with a hydraulic lift system to
raise and lower the unit from transport to planting
position.

Escaping hydraulic fluid can cause serious
personnel injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands (See
Figure 4-7.) Keep all components (cylinders,
hoses, fittings, etc.) in good repair.

together.
2. Before transporting make sure both lift cylinders and
hitch cylinders are fully extended for maximum

3. The Grain Drill can have both positive and negative
hitch weight. Attach the drill to the tractor before
attempting to raise or lower the drill hydraulically.

a. Before starting field operation, fully raise the drill
and remove transports locks (See "Transport
