TRACTOR MAINTENANCE
GENERAL OVERHAUL OF PROXIMA POWER TRACTORS
A general overhaul of the tractor should be carried out if its further use is uneconomical, if most of its parts require a repair and its
overall technical condition endangers traffic safety.
If all the maintenance instructions specified in the technical documentation of the manufacturer are observed and if work is car-
ried out in a moderate climate and plain terrain, the mean service life of the engine and transmission system is 8000 hours of
work.
This number of hours is valid on condition of the following distribution of tractor work:
Ploughing and pre-sowing soil treatment
15 - 25 %
Sowing and planting
10 - 15 %
Harvest work 10 - 20 %
Farming transport
40 - 65 %
If the tractor works in mountainous and sub-mountainous regions, the service life of the engine and transmission system is re-
duced by 15-20%.
If the tractor works under worsened climatic conditions, the service life of the engine and transmission system is reduced by 15-
20%.
Note: The transmission system includes the front driving axle.
TECHNICAL MAINTENANCE OF TRACTORS AFTER A GENERAL OVERHAUL OF THE MAIN GROUPS
Run in the tractor after a general overhaul in accordance with the instructions for running in a new tractor. Perform the mainte-
nance in the same way as with a new tractor.
