When purchasing the new machines to be used together with the tractor, it is necessary
to specify the presence of the necessary working equipment providing for the possibility of
aggregating with the MTZ tractor of your model.
For the machines located behind the tractor and driven from the PTO, it is necessary to
order the cardan shaft of the necessary length and type, with the respective coupling dimen-
sions. The machines driven from the PTO can be equipped with a reduction gear providing
for rotation of the cardan shaft both clockwise and counter-clockwise. When purchasing the
machine, it is necessary therefore to specify whether it is required to equip the machine with
a reduction gear to be driven through the cardan shaft with the direction of rotation of the
power intake shaft counter-clockwise, if looked from the side of drive of the machine towards
the end face of the cardan shaft yoke.
Stage III
Checking the correspondence of the vertical static load on the traction hitch mech-
anism or carrying capacity of the mounted attachment to the load created by the ma-
chine with the account of the weight of the adjusting load.
Make sure in the possibility of lifting and lowering of the attached machine with the total
operating weight by the mounted attachment. Keep in mind that the load created by the ma-
chine shall not exceed the recommended values of the carrying capacity of the mounted at-
tachment and allowable vertical load on the traction hitch mechanism.
Stage IV
Checking the vertical static loads on the axles of the tractor including the steerabil-
ity criteria and necessity of additional ballasting.
Determine the total weight of the tractor with the machine, load on the axles and maxi-
mum allowable load on the tyres, weight of the necessary ballast and adjusting load by the
calculation or experimental method. The weight of the tractor within the MTA distributed be-
tween the tractor’s axles shall not exceed the permitted values. In any case. the load on the
front and rear axles shall not exceed the total load-carrying capacity of the tyres according
to the total load-carrying capacity of the rear or front wheels.
Stage V
Checking the possibility of motion of the tractor aggregated with the machine in-
cluding checking the turn angles and maximum height of lifting of the mounted at-
tachment until it rests against the tractor members, sufficiency of the length and free
space of the cardan shaft when performing turns and transferring the machine to the
transport position.
Stage VI
Assessment of the correspondence of the power capabilities of the tractor and
power required by the machine (draught resistance and power consumption includ-
ing that through the PTO). The assessment may be performed by the calculation tee
given the initial data or based on the test report.
Stage VII
Checking the possibility of performing the work by the machine aggregated with
the tractor.
a. Trial aggregation for performing the jobs in accordance with the purpose of the ma-
chine and with obligatory observance of the safety requirements.
