ATTACHMENT
1° FITTING TO THE TRACTOR
The GA 4511 GM can be fitted to all tractors equipped with a DIN or ASEA Standard 3-point linkage. The lower
hitch pins have a diameter of 22 mm and 28 mm for tractors with Cat. 1 and 2 linkage.
The tractor link arms (A) should be attached to the hitch pins located inside the 3-point frame for Cat. 1 tractors and
outside for Cat. 2 tractors.
In the latter case, use the 25 mm diameter portion of the top link pin.
Connect hydraulic hoses (F) and plug (H) of the lighting equipment (photo 1). To do this a female hydraulic connection
and a 7-pin electric socket are required at the rear of the tractor (photo 1).
Note : Connecting and disconnecting the machine is facilitated when the 3-point frame is unlocked (lock V raised)
(photo 1).
2 ° PTO SHAFT
Connect the PTO shaft to the 540 rpm tractor drive (with the safety clutch fitted 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 (1") must be maintained. If this is not the case, shorten the two transmission
tubes and the two guard tubes by the same length (photos 2 and 3). Bevel and clean the tubes (photo 4) and grease
the inside of the outer tube (photo 5).
3) Never operate the PTO at too great an angle (30° maximum).
These recommendations and adjustments must be respected to avoid damage or premature wear of the PTO.
Never connect the PTO to the 1000 rpm 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 machine side the chain should
be fixed to the lower articulation of the main frame. Damaged guards must be replaced
immediately.
