This is the operator's manual for the Kubota L3240-3, L3540-3, L3940-3, L4240-3, L4740-3, L5040-3, L5240-3, and L5740-3 tractors, a 148-page PDF covering daily operation and owner maintenance of all eight models in both HST and GST transmission versions.
It explains the instrument panel and controls, pre-operation checks, operating the engine and the tractor, the PTO, the three-point hitch and drawbar, the hydraulic unit, and tyres, wheels, and ballast. Maintenance and periodic service sections give the service intervals and checks that keep the tractor running.
With it you can set correct tire pressures and ballast, torque the wheel bolts to spec, follow the engine and hydraulic filter change intervals, adjust clutch and brake pedal free travel, and operate the PTO and hitch safely. Written for owners who run and maintain their own Kubota L-series tractors.
