U741 CULTIVATOR – OPERATING INSTRUCTIONS MANUAL
2. DRIVE OPERATION
2.1. COUPLING THE CULTIVATOR WITH THE DRIVE
Couple the cultivator with the agricultural tractors rated at a
minimum of 80 HP and equipped with the three-point hitch system.
The cultivator is coupled with the tractor in the following way:
•
Reverse the tractor to a distance which allows to couple the machine
with the tractor lower hitch links.
•
Couple the upper 3-point hitch link to the cultivator and remove any
play; then level the cultivator.
•
Connect the electric power supply and do a functional test (the lighting
system is an optional accessory).
•
Connect the hydraulic line and check for proper seal.
•
Lift the cultivator and verify that the tractor front axle load is over 20%
of the tractor weight. The tractor should remain fully steerable. See
Section 2.3.
•
The machine should be adjusted during the first pass.
Be extremely careful when coupling the cultivator with
the tractor. Do not stay between the cultivator and the
tractor when coupling the machines together.
ATTENTION!
2.2. DECOUPLING THE CULTIVATOR FROM THE DRIVE
Do the following to decouple the cultivator from the tractor:
•
Make sure that there are no bystanders, especially children, in the
coupling area.
•
Place the cultivator for storage on a hard, flat and level ground.
•
Disconnect the electric power supply (if applicable).
•
Disconnect the hydraulic line.
•
Disconnect the 3-point upper link and the tractor lower links.
2.3. STABILITY OF THE TRACTOR/CULTIVATOR
ASSEMBLY
The tractor should have appropriate ballast at its front end to provide
proper steering and braking performance. When the machine is coupled
the load on the tractor's front axle must be at least 20% of the tractor's
own weight (Fig. 8).
Remember that the road and the coupled machine influence the
driving characteristics. The driving style should be adjusted to terrain
conditions and type of soil.
While negotiating corners with the coupled or suspended machine, it
is important to bear in mind the reach and weight of the machine.
