OPERATION
HAY CONDITIONER GROUND CLEARANCE
The conditioner body can be raised or lowered to
suit crop and field conditions. Too high a setting
will not allow the rolls to pick up all of the crop,
while too low a setting in stony conditions can
damage the bottom roll.
To adjust ground clearance:
1. Raise header fully. Stop engine, remove key
and engage header lift cylinder stops.
2. Place a 3 to 4 inch block (75 to 100 mm) under
the R/H conditioner shoe as shown at (G). (No
block under left side.)
3. Remove header lift cylinder stops and lower
conditioner onto block. Shut off engine and
remove key.
4. Move R/H chain to desired position in bracket
by inserting head of bolt (H) into keyhole slot.
IMPORTANT: To avoid forming shield damage,
install chain from the outboard side of bracket
as shown.
5. Raise header fully. Stop engine, remove key
and engage header lift cylinder stops. Remove
block from under R/H conditioner shoe.
6. Remove header lift cylinder stops, lower
header to cutting height and check conditioner
float (see following page).
