Hydraulic System
The wrapping machine hydraulic system is
powered from the tractor hydraulic system.
To attach the machine to the tractor hydraulic
system, the attachment cables are connected to
the hydraulic controls and further to the wrapping
machine hydraulic motor.
Figure 11
Through the chain transmission, the hydraulic
motor rotates the drums with the loaded silage
bales. By means of the three-section hydraulic
control unit (Item 1), the hydraulic engine powers
five double-acting cylinders responsible for
[Figure 11] :
• Tilting the rotary table and the unloading unit
to the vertical and horizontal position
• Lifting and lowering of the loading arm
• Rotation of the rotary table
The control over the engine and hydraulic
cylinders is ensured by using the control levers
(Item 3) located in the tractor cabin during
operation
[Figure 11] .
These levers are connected to the three-section
control unit by using Bowden cables. The symbols
on the control unit support inform about the
functions fulfilled by each lever
[Figure 11]
.
The three section control unit (Item 1) is protected
against high pressure from the hydraulic system
by means of a safety valve
[Figure 11] .
The valve (Item 2) is located in the rotating chassis
section and operates only in the table rotation
system rotating clockwise, which is opposite to
the wrapping direction. The purpose of the valve
is to smoothly stop the rotating chassis
[Figure
11] .
Delayed blocking of the rotary table indicates that
the valve must be adjusted properly.
IMPORTANT
Do not adjust the valve behind the control unit. It
is pre-adjusted by the Manufacturer.
Before operating the wrapping machine, check
the operation of the hydraulic system by testing
the following elements without a bale loaded:
• Table rotation
•
Lifting and lowering of the rotary table
• Lifting and lowering of the loading arm
