Braking Valve Adjustment
The braking valve (BV) on the hydraulic manifold con-
trols the stopping time for the cutting deck blades. The
braking valve is adjustable. If adjustment of the braking
valve is correct, the cutting deck blades should come to
a complete stop within 7 seconds after the PTO switch
is disengaged.
If blade stopping time is incorrect, adjustment of the
braking valve (BV) can be performed as follows:
NOTE: Do not remove the braking valve from the hy-
draulic manifold for adjustment.
