Use of the machine
WARNING!
Before using the machine, gain familiarity with the controls and how they work.
Keep all parts of your body inside the tractor cab at all times to minimize the chance of being exposed to possible
hazards outside the cab.
Before getting out of the tractor and before performing any maintenance or adjustment work, apply the parking brake,
switch off the engine, remove the key from the ignition and wait for all moving parts to come to a complete stop.
Your safety and that of anyone nearby depends on your common sense and careful operation of the machine.
Consequently, you must be familiar with the position and function of all controls.
The machine must be kept in perfect working order at all times and must be repaired using original spare parts only.
5.1
Connecting the machine to the tractor
The machine must be connected to the tractor via a PTO running at 540 rpm of a suitable weight and power, in
compliance with current code in the country where it is used.
The machine must fall within the weight, size and power ranges given in the tractor’s user guide.
WARNING!
You must wear suitable Personal Protective Equipment (PPE) when using, adjusting, servicing,
repairing or handling the machine; see Section 2.4.
Connect the machine as follows:
5.1.1.
Back the tractor up so that its rear lift arms are offered up to the machine’s couplers, see Figure 5.1 (1 and 2).
5.1.2.
Apply the tractor’s parking brake, switch off the engine, remove the ignition key and get out.
5.1.3. Insert the hitch pins and relevant safety cotter pins.
5.1.4.
Connect the machine’s adjustable top link, see Figure 5.1 (3), to the tractor, lift the machine until the machine
and tractor power take-offs are at the same height and adjust the adjustable top link so that the machine sits
horizontally; see Figure 1.2.
5.1.5.
Lock the tractor’s lift arms to stop the machine rocking from side to side and thus compromising the tractor-
machine unit’s transverse stability.
5.1.6. Adjust the lift travel stops so that the machine cannot be lifted more than 40 cm off the ground during travel,
see Figure 1.2.
DANGER!
Carefully read the PTO shaft’s operating and maintenance manual (attached to the shaft).
The PTO shaft is an important power transmission device that has been factory balanced, since it rotates at a
relatively high speed, and must not be altered in any way. When the PTO shaft is pulled out as far as it will go,
regardless of working conditions, the telescopic tubes must still overlap by at least a third of their length. When
the shaft’s telescopic tube is pushed in as far as it will go, there should still be roughly at least 4 cm of play. If
this is not possible, seek help from the manufacturer’s technical department. With the machine fully lifted,
make sure the telescopic tubes cannot slip out. Before starting work, make sure: the PTO shaft’s guards are
fitted with the relevant safety chains to stop them rotating and that everything is in an excellent state of repair.
Fit the PTO shaft on the splined shaft belonging to the machine’s gearbox, holding down the safety pin; release the
safety pin and pull the PTO shaft back out until the pin clicks audibly into the relevant slot. If you don’t hear the pin click
into place, repeat the procedure.
