2.14.2 Lowering Speed Adjustment
Select a suitable lowering speed for the farm implement to
keep it from being damaged by heavy impact when it contacts
the ground. Before delivery of the tractor, the descending
speed regulating valve was adjusted. The owner/operator can
readjust the valve according to the weight of farm implement
and ground hardness.
•
To decrease the lowering speed of the farm implement,
turn the adjustment valve (A) clockwise.
•
To increase the lowering speed of the farm implement turn
the adjustment valve (A) counterclockwise.
2.14.3 Application of the Hydraulic Output and Lock
•
Turn the adjustment valve (B) in a counterclockwise
direction until the valve is closed. This will also close the
adjustment valve on the inlet and outlet of the oil cylinder.
The male connector on the quick change coupler is connected
with the oil inlet of the farm implement. The hydraulic output
female connector (A) is connected with the male connector
on the farm implement. Push the distributor control handle to
the lifting position to reach the appropriate hydraulic output.
Simple hydraulic output can only control a single-action oil
cylinder.
•
When using the hydraulic output, the farm implement should
be in the lift position, if the lower speed adjustment valve (B)
is closed and the oil in the tank can not return. The farm
implement should be locked in the transport position and the
adjustment valve can act as the hydraulic lock.
