Blade Braking Valve (BV) Adjustment (Traction Units Prior to No 314000001)
The blade braking valve (BV) on the hydraulic manifold
controls 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.
1. Loosen lock nut on braking valve (Fig. 40).
2. To decrease blade stopping time, turn the adjust-
ment shaft on the valve in a counterclockwise direction.
3. To increase blade stopping time, turn the adjustment
shaft on the valve in a clockwise direction.
4. Tighten lock nut to secure adjustment.
5. Check blade stopping time and readjust braking
valve as needed.
