3. ADJUSTMENTS AND DRIVING
PARKING
Fig. 3-7
1) Release the transport lock B.
2) Lower the link arms so that the top link can be disconnected from the
headstock.
3) Lower the jack of the machine.
4) Disconnect hydraulic hoses and the PTO shaft from the tractor.
5) Lower the link arms until the machine rests on the ground, release the link arms
and drive the tractor away.
WORKING IN THE FIELD
BASIC ADJUSTMENTS
Fig. 3-7
Raise the machine.
The machine must be in working position with the transport lock B released.
Actuate the valve by pulling the cord and move the machine to working position
beside the tractor.
Lower the machine.
Fig. 3-8 Adjust the double-acting hydraulic outlet to floating position. Raise/ lower the link
arms until the machine is at the correct working height. This is obtained when the
indicator A is at level with the arrow on the transfer B as described in chapter 2.
CAUTION:
Stop the tractor engine, remove the ignition key and activate the
parking brakes before changing the adjustments of the
machine.
STUBBLE HEIGHT
From the factory the machine is constructed to cut with a theoretical cutting height
from 22 mm to 45 mm. This means that the real stubble height will be from
approximately 45 mm to 90 mm.
(Usually the stubble height is 2 x theoretical cutting height.)
Fig. 3-9 Rough adjustment of the stubble height is made in 2 steps with the pin D at guide
shoe E in the right and left-hand side (the bottom hole gives a low stubble). Fine
adjustment is made by lengthening or shortening the top link.
If you want an extra high stubble, e.g. when topping fallow fields, high guide shoes
which are available as optional equipment can be mounted. See spare parts book.
IMPORTANT: To reduce the wear of blades and discs and to improve the
possibility of regrowth, the stubble should never be lower than
60 mm.
In stony fields, adjust the stubble height to maximum and be
particularly careful.
STARTING
CAUTION:
Before starting check that the guards are intact and that no
persons are near.
Before driving into the crop, increase the PTO to 1000 rpm.
Always make sure that the number of revolutions is not reduced considerably during
the operation as this might result in an unsatisfactory cut.
Always adjust the driving speed to the conditions of the ground.
