HYDRAULIC SYSTEM OPERATION

HYDRAULIC SYSTEM

The tractor is equipped with a specially designed hydraulic system that consists of a hydraulic reservoir, a load-sensing variable-flow hydraulic pump, an implement valve assembly with flow control capability, quick couplers, a filter and oil coolers as standard equipment.

Optional equipment available for the hydraulic system include a 3-point hitch and a 1.9mm (3/4″)coupler kit for high flow requirements. These optional features can be dealer or factory installed.

The steering system of the tractor uses a separate constant displacement pump to supply oil to the steering valve. The steering pump oil is also supplied to the implement valve (when required) to supplement hydraulic pump flow

during high flow demand situations (i.e., air seeder operation). Steering oil flow has first priority for the steering circuit, then supplementing implement valve oil requirements.

The steering system consists of a constant displacement pump, a P.O. valve, priority valves (2), a closed center steering motor and steering cylinders.

The steering system shares the hydraulic reservoir, filter and oil coolers with the hydraulic system.

Figure 2-162 shows the complete layout of the hydraulic system.

Figure 2-163 shows the orientation of hydraulic components on the tractor.
