5. DRIVE OPERATION
5.1. Drive coupling
The bale wrapping machine should be coupled with tractors with rated power not lower than
40HP and traction class 0.9 equipped with a three point hitch.
The wrapping machine SPIN F shall be coupled to the lower hitch or to the upper hitch
allowing for the maximum vertical load of 1.2 kN. The wrapping machine SPIN S shall be coupled
to the lower hitch or to the upper hitch allowing for the maximum vertical load of 4.7 kN.
CAUTION!
Make sure that there are no bystanders, especially children, in the coupling
area.
NOTE:
Before coupling the equipment, place the tractor axis in the machine‘s axis
on a hard, flat, level ground. Turn off the tractor engine, remove the ignition
key and engage the tractor parking brake. Level the wrapping machine by
selecting the appropriate adjustment opening in the hitch.
CAUTION!
Couple the hitch-ring only with the lower hitch and check whether the
machine is properly connected and secured against accidental disconnection.
CAUTION!
Make sure that the tractor‘s hydraulic system is sealed.
Connect the electric power source. Check if the operating and signalling systems work
properly.
Connect the hydraulic power source. Check if the hydraulic systems work properly,
especially the lifting and blocking mechanisms responsible for controlling the working and
transport positions.
Load the first bale and make sure that the vertical load on the tractor’s front axle is larger
than 20% of the tractor;s weight. The tractor should remain fully steerable.
5.1.1. Coupling with the upper transport hitch – for: SPIN S
The wrapping machine may be coupled with tractors equipped with an upper transport hitch
able to transfer vertical loads in excess of 4,7 kN (470 kG).
In order to attach the machine to the tractor upper hitch, follow these steps:
Set the suport stand (4) of the wrapping machine in a position which allows the front of the
frame to rest on the ground as shown in the illustration Fig. 14.
