STROKE LIMITER (HEIGHT STOP) VALVE ADJUSTMENT
Field turn around height of toolbar should measure 99 cm - 104 cm from ground if stroke limiter valve is correctly
adjusted.
1. Lower planter to ground and hold hydraulic lever for 15-20 seconds to rephase system.
2. Check rod assembly adjustment bolt is set at 15¾" (400 mm) pin to pin when planter is fully lowered. Adjust as
needed.
3. Check stroke limiter (height stop) valve plunger is depressed and pointing in a straight line to center of pivot shaft
on cam activator.
4. Loosen detent arm (height stop assembly) clamping bolt and rotate detent arm over depressed stroke limiter
valve plunger. Valve plunger should be fully depressed when detent arm is rotated over plunger arm, but must not
bind. If binding occurs, move valve assembly away from detent arm while keeping valve plunger aligned with pivot
shaft. Slide stroke limiter valve up or down in slotted mounting holes as needed to adjust. Tighten stroke limiter
valve mounting bolts and recheck adjustment. Be sure detent arm is positioned as shown and tighten detent arm
clamping bolt.
5. Raise planter until stroke limiter valve (height stop assembly) halts lift cylinder. Toolbar should measure 99 cm - 104 cm
from ground. If adjustment is needed, loosen detent arm clamping bolt and rotate detent arm counterclockwise to reduce
and clockwise to increase lift height. Tighten clamping bolt and mark a line on detent arm and cam activator shaft for
easier alignment later.
NOTE: When lowering from transport position, planter toolbar should level out to a height of 99 cm - 104 cm
from ground at field turn around. If it doesn’t, rephase and/or remove air from the hydraulic lines and recheck
toolbar height. Repeat above adjustments as needed.
