7.4 Pinch Point Position
The pinch point position can be adjusted by a spacer (G),
part number 50139. In muddy conditions, roll the pinch
point forward by adding spacers. This will pop the beet
faster and with less mud. For dry or hard digging condi-
tions, roll the pinch point back by removing spacers, giving
the wheels a longer time to lift the beet and reduce break-
age in the ground. The extra dirt will lift the beets high
enough for the paddles to send them into the machine. To
adjust the pinch point position
:
Figure 7 - 5: Pinch Point Adjustment
1. Loosen the two nuts on the front of the strut.
2. Add or remove spacers (G) to adjust the pinch point
forward or back.
3. Re - tighten the hex nuts when desired position is
reached.
Figure 7 - 6: Pinch Point Height
NOTE: The addition of one spacer (G) will
decrease the pinch point height by ½ inch
(1.3 cm) and two spacers by 1 inch (2.5
cm). Numbers are approximate.
NOTE: If harvester is equipped with rock
cushion struts, be sure that the rock cush-
ion is tensioned to 4.5 inches (11.4 cm]).
If the rock cushion is not tensioned
properly it will affect pinch point position.
Also, it may decrease performance of the
rock cushion.
