5. HYDRAULIC
5.1 HYDRAULIC SYSTEM
In this tractor live hydraulic system is provided. In which hydraulic pump is driven by
engine and mounted with timing gear of engine. As the engine run, the hydraulic pump
also starts working. Transmission lubrication oil is coming with hydraulic oil. Hydraulic
system senses the load on implement through draft sensor provided at top link
Mounting bracket of three- point linkage. You can operate position control, draft control
or mixed control.
5.2 HYDRAULIC CONTROLS OPERATIONS
5.2.1 POSITION CONTROL OPERATION
Position control (A) is used to raise hold and lower three point linkage for mounted
implements during tillage/field operation e.g. Mounted Disc Harrow, Seed Drill,
Rotavator, Disc Plough, Ripper etc., which works above the ground. Once the height
of implement is set, position lever maintains it. Always use Position lever for
transporting the implement. One adjustable locking knob is provided for maintaining
the specific position.
5.2.2 DRAFT CONTROL OPERATION
Automatic Draft Control(B) is designed to respond at the time of sudden resistance
faced by the mounted dragging type implements i.e. Cultivator, Plough, and
Reversible Plough etc. while working in the field. Keep both position and draft
lever(Black & Red) in lower most position (implement grounded) now move the draft
lever (Red) towards up side position on sector as implement starts rising move back
the lever by few mm.Prevents: Overloading of engine, breakage of implements, clutch
slippage, tyre slippage, and excess fuel consumption.
5.2.3 MIXED CONTROL OPERATION
Simultaneous use of position control and draft control lever is called mix control. If the
ground is not uniform and has soft areas where the implement can sink too deep then
mix control is performed because in this situation draft control does not function
properly. Use the same. Procedure as for work in draft control then draw a furrow up
the field, when the ground becomes sandy, the implement tends to sink in deeply. In
this case, bring the position control lever backward to limit the working depth. Now set
the position lever in this position.
5.2.4 DIRECTION CONTROL VALVE OPERATION
This operation is performed when external hydraulic cylinders are operated by tractor.
To full the external cylinder shift the operating lever in forward and for draining the
cylinder set the DCV Lever down in backward direction.
NOTE: At the end of the furrow, bring the position lever backward to raise implement fully. To bring implement is working position lower
the position lever to the previous position marked on the position sector by knob.
Always use position lever while joining the implement and transporting the implement.
During transportation while holding implement in raised position, always close the response valve to prevent any accident.
