The L6060 is powered by a Kubota four cylinder 148.5 ci  E-TVCS liquid-cooled common-rail indirect injected turbo diesel that uses exhaust gas recirculation (EGR) and a diesel particulate filter (DPF) muffler to achieve those tightened emissions standards. Power take off (PTO) horsepower is 53 at 2700 engine rpm. Fuel capacity is 11.2 gallons, which seems a little low compared to some of the competition – a price paid perhaps for that nice 20 percent increase in cab space.

Though the Grand L60 Series comes with three choices of how to get that power to the ground: 12 speed Glide Shift Transmission (GST), 8F x 8R Fully Synchronized Shuttle Transmission (FST), and Hydrostatic Transmission (HST) Plus, the L6060 only comes with the latter hydro unit. But what a transmission it is. With three ranges and two additional speeds fingertip selectable on the steering column (Auto H-DS) within each range, the L6060 effectively gives the operator six ranges. This means infinite control over the 0-10.1 / 0-16.8 (L/H) mph forward and 0-9.1 / 0-15.2 (L/H) mph reverse speed ranges. Control is by a modified treadle pedal that gives the operator a choice of standard toe/heel operation; or for those so inclined, the ability to go forward by pushing down with the toe and reversing by slipping the toe under the pedal and lifting up. Either way, the system offers well-modulated directional control.
