Abstract: There is provided herein an electric tractor having a particular chassis configuration affording versatility and ease-of-use advantages for hobby farming, light industry and the like. The tractor comprises a pair of parallel spaced apart bogies comprising a battery power supply and an electric drive componentry for respective drive wheels thereof. Rearward bracing structurally interconnects the bogies, preferably arched thereover. Furthermore, a pair of pivotally coupled booms extent forward of the bracing and have respective linear actuators at proximal ends thereof for raising and lowering the booms and mechanical device attachment coupling at distal ends thereof. Such sparse tractor chassis allows space between the bogies and the booms suitable for the attachment of various operational accessories and operation thereof which may include a carryall deck that fits between the bogies for carrying of produce and the like, buckets, forklift tines, rotary hoes, flail mowers, power harrows and the like.

Abstract: Disclosed power machines (100; 200; 300; 400; 500) include a lift arm structure (230; 330; 430) having a first arm (234; 334; 434) pivotally mounted to a frame and a second arm (236; 336; 436), coupled to an implement interface (270; 370; 470), configured to telescopically extend from and retract into the first arm. A control system (160; 260; 360; 460) controls a first actuator (238; 335; 435) to raise and lower the first arm, and controls a second actuator (239;) to extend and retract the second arm relative to the first arm. The control system is configured to control the first and second actuators to implement a lift operation, responsive to an operator input. During the lift operation, the first actuator raises the first arm and the second actuator extends and retracts the second arm to maintain a substantially linear path (339; 439), such as a vertical path, of the implement interface or an implement attached to the implement interface.

Abstract: A load handler with a modular frame and the manufacture and assembly of the frame and loader and components that may be used therein. A frame is provided that has a low pivot point for a boom. The frame has left and right side rails, and front and rear cross rails, each having a closed cross-section construction. The side rails and cross rails are modular and the cross rails of a selected size are configured to fit a plurality of sizes of side rails, such that the same size cross rails may be used to construct a variety of sizes and capabilities of load handling vehicles in a flow type manufacturing process. A structural beam is provided having plates interconnected along their lengths to form the beam having a box-shaped closed cross-section having a perimeter generally along the widths of the plates and forming a beam cavity within the perimeter.
