CHAPTER IV – THE PREPARATION OF THE TRACTOR PULLING – Page 3
4.4. LEVERS OF THE LIFTING ARMS
The
lifting axis must be vertical to the levers (3) in fixed position (4) to avoid all unnecessary clearance
during turning or dangerous jerking.
4.5. THE LENGTH OF THE LIFTING LEVERS
Examine the proper work of the vertical bars of the lifting levers. Before attachment to the tractor it
is easier to loosen the lifting lever screws and perform their lubrication.
The lifting bars of the vertical levers must be in fixed
position.
Be sure that both lifting bars are the same length
because the difference between left and right lifting bar
s
may result the wrong a
djustment of the vertical position.
This way the plough can work deeper on one side or the
first furrow width will not be suitable.
The length of the lifting bars affects the position of the
tractor lifting levers. The tractor depth controlling
will be
the better if the lifting ba
rs can oscillate (in the function of
loading to le
t out and pull in)
So it is nece
ssary to adjust the lifting bars length to have minimum 30 mm going (5) to be able to pull
them back during the work.
Special attention must be paid if the tractor is equipped with wheels of big diameter.
