Hydraulic Lift System - Landoll Tilloll 877 Operator's Manual

Hydraulic Lift System

The Tilloll is equipped with a rephasing hydraulic lift
system to raise and lower the unit in the field.

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
Figure 4-2) Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
1. The rephasing hydraulic lift system contains smaller
wing frame cylinders plumbed in series with larger
center frame cylinders. It is important that the
cylinders be connected in the proper series for the lift
system to operate correctly. When the cylinders are
fully extended and held in this position, oil is able to
flow through the cylinders (or rephase) and allow the
cylinders to operate in sync. This also allows the
system to purge any air that may enter the system
without having to loosen or crack hydraulic lines.
2. The hydraulic system is not filled with oil and should
be purged of air before transporting and field
operations. Carefully hitch the Tilloll to the tractor
and connect the hydraulic lift hoses. Check to make
sure the tractor hydraulic reservoir is full of the
manufacturer's recommended oil. Slowly raise the
machine, and continue to hold the hydraulic lever
until all lift cylinders are fully extended. Lower and
raise the unit to verify that all cylinders are working
simultaneously throughout the stroke. If the cylinders
are not working evenly or together, fully extend the lift
cylinders and continue to hold the lever to purge any
remaining air. Do not loosen any hoses or fittings.
Recheck tractor reservoir to make sure it is within
operating limits. With all cylinders fully extended,
install the 2 X 8 transport lockouts

OPERATION AND MAINTENANCE
3. Always fully extend the cylinders and hold the lever to
ensure the cylinders are rephased before starting
any field operation. This will keep all cylinders in time
and frame sections level when operating.
