Variable Ratio Adjustment - Landoll 2131 Operator's Manual

OPERATION AND MAINTENANCE

Variable Ratio Adjustment

The leveler is equipped with a variable ratio adjustment.
This is located at the rear of the hitch and at the center of
the wheel lift where the leveler tube attaches. Connect
the leveler tube to the top hole in the center lift and the
bottom hole in the tongue for normal operation. This will
cause the rear of the machine to raise higher than the
front increasing transport height. The lower hole on the
center lift provides an increased leveler ratio, which will
cause the Coulter Chisel to become more level in
transport. The lower hole should be used when a rear
tow hitch is needed to reduce the height of the rear tow
hitch during transport.
The adjustments can be set as follows:
• Top hole in center lift, top hole in tongue - this will
raise the rear of the machine the highest.
• Top hole in center lift, bottom hole in tongue - normal
operation.
• Bottom hole in center lift, top hole in tongue - normal
operation with a tow hitch
• Bottom hole in center lift, bottom hole in tongue - to
lower rear tow hitch if needed.
