Floating
1. When the hydraulic control lever is set to the
"FLOAT"
position, the spool (3) moves further to the right from the
"DOWN"
position and is retained by the detent mechanism (5).
2. This forms oil passages among the
A1
port,
B1
port and
T
port. As a result, oil in the boom cylinder (7) flows freely
from the
A1
port and
B1
port through the
T
port to the transmission case.
3. Oil entering the
P
port flows to the bucket control section (2) through the neutral passage 1 (6) and
PB
passage
1 (4).
