(2) Grass Collector Dumping Circuit
Suppose that the mower lifting spool (spool 1) (1) is in
the neutral position.
■
Neutral
The oil coming from port P flows to port T1.
Port A and B that are connected with the grass
collector cylinder are kept closed by the spool 2 (for
grass collector cylinder) (2). In this way, the grass
collector (container) is held at a certain level.

■
Open
Move the grass collector dumping lever to the “LIFT”
position, and the spool 2 (for grass collector cylinder) (1)
is activated in the direction shown in the figure.
This cylinder is of double-acting type.
The oil coming from port P flows through port B into
the grass collector cylinder.
The oil in the grass collector cylinder, on the other
hand, flows through port A into port T1. In this way, the
grass collector is lifted.
