tractor for performing non-agricultural kinds of works as a power source by aggregating the
machines in the MTA using standard working equipment intended for aggregating.
Qualification of the servicing personnel:
The operation of the tractor by driving and aggregating the same shall be allowed to the
persons (hereinafter referred to as tractor drivers, operators) having passed special training
and instruction on the matters of the labour protection, having the documents in the form
provided by the legislation for the right of driving a tractor and having obtained the permit for
operation of a specific tractor.
The owners as well as officials and other persons responsible for the technical condition
and operation of the tractor are barred from allowing the tractor to participate in the road
traffic and be operated with violation of the requirements of the road regulation and this
Manual for the tractor. The owner of the tractor (or person responsible for its operation) shall
read carefully this Manual and fulfil all the safety requirements and operation rules stated
therein.
Should the owner of the tractor (or person responsible for its operation) does not work on
the tractor him/herself, he/she shall make sure obligatorily that all the persons pertaining to
the tractor have got the instructions for safety precautions and correct aggregation of the
tractor with machines as well as read carefully the Operating Manual for the tractor and un-
derstood comprehensively the same.
The tractor driver working on the tractor bears the personal responsibility for observance
of the road regulations and safety precautions as well as for correctness of using the tractor
in accordance with the Operating Manual for the tractor. Prior to performing the works, the
tractor driver shall read also the technical documentation for the machine to be operated
with the tractor.
2. Types and classification of agricultural machine-tractor aggregates based on the
MTZ tractors
The agricultural aggregates operated on the basis of the MTZ tractors are classified ac-
cording to the following operational signs:
Kind of the process to be carried-out: ploughing, sowing, planting, soil-cultivating,
harvesting and others.
Method of performing the works: mobile (performing the work in the process of mo-
tion; stationary-mobile (performing the work in the stationary or moving state); stationary
(performing the work under stationary conditions, when the tractor does not move).
Type of driving the tools of the machine: tractional, tractional-and-driven and driv-
en. The tractor-based tractional aggregates utilize the whole useful power through a traction
hitch mechanism or mounted attachment.
The useful power of the tractional-and-driven MTA is utilized simultaneously by trac-
tion via traction hitch mechanism of the tractor and through mechanical and/or hydraulic
power intake via PTO shaft and free hydraulic outlets of the tractor. The driven MTA’s per-
form the work under stationary conditions (the tractor does not move) through mechanical
and/or hydraulic power intake via PTO shaft and free hydraulic outlets of the tractor. A
transport MTA is a particular example of the tractional aggregate.
