Repair of a hydrostatic transmission of a combine is a complex technical procedure on which the efficiency, reliability and durability of agricultural machinery depend. LLC “Hydraulic Line” (Kyiv) specializes in professional repair, maintenance and diagnostics of hydrostatic transmissions (HST) of combines of leading world brands.
A hydrostatic transmission (HST) is a closed-type drive consisting of a hydraulic pump, a hydraulic motor, control valves and a working fluid supply system. Its main advantage is smooth movement, efficient power transmission and the ability to precisely adjust the speed of the combine at high load. But over time, even the most reliable systems require qualified maintenance.
Causes of hydrostatic transmission failure
wear of hydraulic pumps or hydraulic motors;
contamination in the working fluid;
damage to seals or valves;
improper operation or overload of the equipment;
overheating of the system or oil leakage.
In such cases, professional repair of the combine harvester's transmission is required, which guarantees the full restoration of the equipment's operating characteristics.
