Instrument panel consists of Tachometer, hour meter, engine oil pressure, fuel gauge and audiovisual gauge for transmission oil pressure.

Charging (Ammeter) Dynamo, water temp. Control switch for lights. Engine fuel shut off-stop lever.

Steering column has the electrical controls for turning indicator, dip switch while driving wiper control etc. and for forward reverse direction selection.

Axle and final drive

Rear Axle: Drive axle rigidly mounted, forward and reversing shuttle Gear Box 4 speed Sychromosh gear box in rigid axle housing with a torque conversion.

Front Axle: steer axle centrally pivoted with oscillation angle of 20ototal

Brakes: Hydraulically actuated dual line, self adjusting oil enmersed multidisc type on the rear axle, well protected, requires literally no maintenance.


Hand operated disc brake on Rear Axle.


Front wheel has the hydrostatic power steering with manual capability in the event of hydraulic system failure form high pressure hydraulic oil is directly supplied via priority valve with a working pressure.
