Adjustment of chassis height from the
ground :
1. For tractors equipped with hydraulic position
control function : set lower link height so that roll
pin (F) is exactly centered in its aperture (H) (photo
23).
This gives height E = 400 mm approximately (photo
22), which corresponds to a cutting height of 30
mm.
2. For tractors not equipped with hydraulic
position control function , the stop-chain (L) which
is delivered with the machine must be used.
Proceed as follows to install this chain (L) (photos
24 and 25) :
- Remove roll pin (K) from right hitch pin, attach
chain (L) and washer (M) and reinstall roll pin (K).
- Lower machine until hitch pins (T) are 400 mm
(16") or slightly more from the ground [roll pin (F)
is slightly excentered in regard to its aperture (H)].
- Attach stop-chain (L) with its hook (O) to the
uppermost free holes at the tractor’s top link
attachment clevis (photo 25).
- Lower the machine into working position. Chassis
height is correct when :
- The cutterbar unit is resting on the
ground
- Stop-chain (L) is tight.
- Roll pin (F) is exactly centered in its
aperture (H) (photo 23).
- To keep this adjustment permanently, close hook
eyelet (O) with roll pin.
WARNING : BEFORE LOWERING THE MACHINE IN WORK POSITION, ENSURE ALL
PERSONS ARE WELL CLEAR OF THE MOWER PIVOTING AREA.
