Section I
. COUPLING OF IMPLEMENTS
General information provided in this Sec-
tion will help to use efficiently tractor with a
great variety of agricultural machines and
implements.
As regards the method of coupling with
tractors, the machines are classified as
follows:
• The tractor-mounted ones are to be
attached to the tractor’s three-point
hitch linkage. The machine weight in
the transport position is fully transferred
to the tractor.
• The semi-mounted ones are to be at-
tached to the three-point hitch linkage
run on supporting wheels. The machine
weight in the transport position is partly
transferred onto the tractor and partly is
supported by the wheels of its own.
When rearranging the machine from the
working position to the transportation
one, the point of attachment to the trac-
tor is forcedly shifted to a new position
as to height.
• The semi-trailed ones are to be at-
tached in the same way as the semi-
mounted are, but when rearranging the
machine from the working position to
the transportation one, the point of at-
tachment to the tractor does not change
its position as to height.
• The trailed ones are to be attached to
the haul-and-draw coupling arrange-
ment of the tractor. The machine weight
is carried by its own running gear.
When rearranging the machine from the
working position to the transportation
one, the point of attachment to the trac-
tor does not change its position as to
height.
• The fitted ones are to be attached to
the tractor by means of additional as-
sembly units using the mounting holes
available on the tractor. The machine
weight is fully taken by the tractor.
The MTZ tractors are equipped with stan-
dard lift linkages and drawbar hitches and
also with mounted holes and provide all
types of coupling. In addition, the provi-
sion of a power take-off shaft (PTO) and
free outlets of the hydraulic system make
it possible to drive tools of the attached
machines/technical facilities by either me-
chanical or hydrostatic method.
Below there is information about the trac-
tor working equipment possibilities; the
methodology of choosing the machines for
coupling with tractor, also are given ad-
missible loads of the tractor when com-
bined in a machine-tractor aggregate.
