A gang reel mower has a hybrid engine, generator and battery pack electric power system driving a pair of electric wheel motors for propelling the mower and for driving individual reel motors for powering a plurality of reel cutting units. A master controller is programmable with a selected clip and maintains the selected clip whether the mower travels straight ahead or is turning. The output power of the generator is damped and is gradually increased during high electrical loads to prevent step responses in the engine and thereby limit engine droop. During regenerative braking of the mower, the generator can be driven as a motor to use the engine as a load. This limits the voltage produced by the traction motors during regenerative braking from damaging the electrical system or overcharging the battery pack. Moreover, maximum transport and mowing ground speeds are automatically reduced during some turns of the mower.

Differential speed stalk rolls mountable to a row unit of a row crop head. A first stalk roll body has an outer peripheral speed less than the outer peripheral speed of a second stalk roll body in lateral spaced relation. The stalk roll bodies may have modular and interchangeable body segments of different configurations.

A triplex greensmower open foot platform provides an opening in front of an operator seat providing visibility from the operator seat to a center reel cutting unit. The opening has sufficient dimensions for removal or installation of the center reel cutting unit or a grass catcher therethrough. A pair of platform sections provides a perimeter at least partially around the opening. Each of the platform sections including a footrest and a rearwardly extending coupling that is manually removable from the triplex greensmower.

An all-electric turf vehicle, wherein the vehicle comprises a chassis; a plurality of ground engaging wheels operatively connected to the chassis, wherein at least one of the ground engaging wheels is a steerable wheel; a plurality of electric wheel drive and tractions motors, wherein each electric wheel drive and tractions motor is operatively connected to a respective one of the plurality of ground engaging wheels and is structured and operable to deliver motive power to the respective ground engaging wheel; a plurality of turf cutting units; and an operator station. The operator station comprises a seat in which a vehicle operator can be seated; and a control and support arm pivotally movable so that the control and support arm can be positioned to not obstruct a line of sight of the vehicle operator to an outer edge of an outermost of the plurality of cutting units.
