TRACTOR ADAPT ATION

1) FITTING TO THE TRACTOR

The GA 9321 H/P can be fitted to all tractors with a standard three-point linkage Cat.2 or 3 and an engine rating ranging 74 kW (100hp). The swivel hitch is equipped with two attachment yokes (1) to be connected to the tractor’s lower links(2) (photo 1). Attachment should always be made inside the yokes (1). Two bushes (diameter 37mm/ 1 1/2") are supplied with the machine for attachment to cat.3 tractors. Always make sure the tractor lower links are immobilized using the means provided (check chains, etc…) Using the tractor 3-point lift, position the attachment frame so that the tractor lower links are 750 mm (2’6") above ground level (horizontal carrying frame). Connect:

- The hydraulic hoses (3) (check that the oil flow direction in the machine is respected).

- The 7-pin (4)electric lighting socket (photo 2).

- The 3-pin (5) control box supply socket.

Depending on the machine braking system connect:

- the two pneumatic hoses (8) (photo 3a)

- the hydraulic braking hose

When the machine is attached to the tractor, retract parking stand by pulling on handle (7) and pivot it (see arrow) until lock automatically engages (photo 3). A handle on the parking stand makes it easier to operate.

- 12 -

- 13 -

2) PTO TRANSMISSION SHAFT WITH CONSTANT VELOCITY JOINTS

Connect the PTO shaft to the 540 rpm (min-1) tractor drive (outer guard tube on the machine side). Make sure PTO length is correct :

1) When the PTO is in its maximum extended position, a minimum tube overlap of 300 mm (12") must be maintained. 2 ) When the PTO is in its maximum overlap position (retracted), tubes must not butt against the yokes. As a safety

measure a clearance of at least 2 cm (3/4") must be maintained (fig. 16). If this is not the case, shorten the two transmission tubes and the two guard tubes by the same length (fig.12 and 13). Bevel and clean the tubes (fig.14) and grease the inside of the outer tube (fig.15).

These recommendations and adjustments must be respected to avoid damage or premature wear of the PTO.

Never connect the PTO to the 1000 rpm (min-1) tractor drive.

To avoid accidents which could be serious, make sure that the guards are always correctly in place and secured with the safety chains provided . On the side of the machine, the chain should be fixed on the hydraulic hose holder. Damaged guards must be replaced immediately.
