TRACTOR MAINTENANCE
OVERHAUL IN PROXIMA TRACTORS
Overhaul of the tractor is necessary if its subsequent use is not economical, most of its parts require repair or the overall technical
condition endangers safety of transport.
If all instructions for maintenance are followed in accordance with the manufacturer’s documentation and in work in moderate cli-
mate and on flat terrain the engine and gear mechanism average service life is 8000 hours of work.
The number of hours of work shall apply to the following distribution of the tractor work:
ploughing and ground preparation for sowing
15 - 25 %
planting and sowing 10 - 15 %
harvesting 10 - 20 %
agricultural transport 40 - 65 %
If the tractor works in mountain and piedmont areas, the engine and gear mechanism service life is reduced by 15-20 %.
If the tractor works in severe climate conditions, the engine and gear mechanism service life is reduced by 15 - 20 %.
Notice: The front driving axle is considered a part of the gear mechanism.
TECHNICAL MAINTENANCE OF TRACTORS AFTER OVERHAUL OF UNITS
Initial run of the tractor after the overhaul should follow instructions for initial run of a new tractor. Maintenance is the same as in a
new tractor.
