An all electric riding bunker rake primarily suited for maintaining sand traps, or bunkers on a golf course. It is embodied as a tricycle-style vehicle having a frame supported on three wheels, an electrically actuated rake lifting mechanism at the rear of the vehicle supported by the frame, and a removable rake attachment connected to the rake lifting mechanism. The rake is dragged on the sand behind the vehicle to smooth the sand in a bunker. An electric motor drives the rear wheels through a gear box, and a regenerative type braking system works in conjunction with the electric motor to slow the vehicle whenever it exceeds eleven miles per hour when driven, or two miles an hour when unattended. The frame supports an onboard electrical battery power source and a hood to which a seat is attached on which the operator sits to control the operation of the vehicle and the rake lifting and lowering function. The rear wheels have drum brakes actuated by a foot pedal which has a parking brake linkage integral with it. An electrically raised and lowered cultivator is also attached to the vehicle between the front and rear wheels to aid in breaking lumps of sand before the rake smoothes the sand.
