Stage II
Checking the assemblability
Assessment of the construction compatibility of the mating members of the tractor (trac-
tion hitch mechanisms, three point mounted attachments; hydraulic and electrical connec-
tions; pneumatic heads; PTO shanks) with the respective members of the machine includ-
ing the compliance of the track and standard size of the wheels with the requirements of
the technique of the works performed, location of the PTO, power intake shaft and cardan
shaft of the machine as well as possibility of the installation of the system for automated
monitoring of the process and installation of the monitoring board from the complete set of
the machine in the cab.
Check the availability of the necessary equipment for aggregation in the standard
equipment of the tractor: required type of traction hitch mechanism, pneumatic head, elec-
tric socket, required type of the PTO shank, wheel tyres of the required standard size for
twinning, front or rear hitch linkage, reverse control station, spacers for twinning the
wheels, availability of the hitching hoses and quick-connection cut-off clutches. The miss-
ing equipment of the tractor shall be acquired additionally. After checking the availability of
the necessary working equipment and installation of the necessary additional equipment of
the tractor, perform the completing and preparation of the MTA with the account of the
recommendations of the operating documentation for the technical means to be aggre-
gated.
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 BELARUS 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 di-
mensions. The machines driven from the PTO can be equipped with a reduction gear pro-
viding for rotation of the cardan shaft both clockwise and counter-clockwise. When pur-
chasing 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 mechanism
or carrying capacity of the mounted attachment to the load created by the machine 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
machine shall not exceed the recommended values of the carrying capacity of the
mounted attachment and allowable vertical load on the traction hitch mechanism.
Stage IV
Checking the vertical static loads on the axles of the tractor including the steerability cri-
teria 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
between 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 ac-
cording to the total load-carrying capacity of the rear or front wheels.
