A self-propelled agricultural working machine comprising: a drive module with a load-bearing chassis; agricultural implements for performing an agricultural operation; an electronic control unit for controlling the ground-engaging member; and an operator station with an operator interface, the operator station configured to be removably attached to the load-bearing chassis.

An implement operating apparatus has a U-shaped drive frame supported on drive wheels, each pivotally mounted about a vertical wheel pivot axis. A steering control selectively pivots each drive wheel. A power source is connected through a drive control to rotate the drive wheels in either direction. First and second implements are configured to perform implement operations and to rest on the ground and when the drive frame is maneuvered to an implement loading position with respect to each implement, the implement is connectable to the drive frame and movable to an operating position supported by the drive frame. When the implement is in the operating position, the steering and drive controls are operative to move and steer the drive frame and implement along a first travel path or a second travel path oriented generally perpendicular to the first travel path.

A modular and reconfigurable autonomous electric robot capable of adapting to any type of condition and work in an agricultural environment, comprising: a symmetrical chassis comprising a front part, a middle part and a rear part; a power supply located at the front of the chassis; an implement located at the rear part of the chassis; two wheel assemblies each located at transversely opposite ends of the front of the chassis and two wheel assemblies each located at transversely opposite ends of the rear of the chassis; a GNSS unit to geolocate the electric robot in real time; and a processing and control module that controls the electric robot and is in data communication with the GNSS unit, where each wheel assembly located at the front of the chassis comprises a wheel with an electric motor directly coupled to the wheel.

A U-shaped drive frame has abase beam and parallel side beams defining an open implement area. Drive wheels support the side beams, and each drive wheel rotates about a horizontal drive wheel axis perpendicular to the operating travel direction. A steering control steers the drive frame in the operating travel direction. Implements are configured to perform implement operations and to rest on the ground surface when in an idle position. The drive frame moves rearward to a loading position where each implement is movable to an operating position supported by the drive frame. Each implement provides a beam lock connection between the side beams that resists twisting movement of the side beams to maintain the drive wheels and the side beams in a substantially fixed relationship with respect to each other.

A battery-operated electric hydrostatic utility tractor is disclosed. The utility tractor is a zero-emissions and more capable of powering work attachments to many chores. The tractor frame is supported by ground wheels and is configured to operative couple work accessories. The work accessory has a power connection to couple with an electric source or a pressurized hydraulic fluid carried by the utility tractor. A hydrostatic pump is configured to produce the source of pressurized hydraulic fluid and includes an integrally contained transaxle for selectively providing a hydraulic motive force to a driveshaft for each of an opposed pair of drive wheels. An electric motor has an output axially aligned with an input shaft of the hydrostatic pump, for developing the source of pressurized hydraulic fluid by the hydrostatic pump. A plurality of battery compartments are compartments configured to receive a rechargeable battery to provide the electric source.

A turf cutting machine, more particularly a four-wheel drive turf cutting machine, is provided. The turf cutting machine has a transmission arrangement which includes a transmission belt arranged between a rear axle pulley and a front axle pulley and which further includes a plurality of deflection pulleys which are arranged between the rear axle pulley and the front axle pulley so as to define a path for the transmission belt that extends from a rear axle to a front axle and then back to the rear axle passing over a cutting blade.

A middle mounted implement tractor utilizes a movable frame design in order to provide for middle mounting of implements on a tractor that can drive up to the implement, raise its front portion in the air, drive forward over the implement, and then lower the front portion to the ground and attach the middle mounted implement. This is accomplished utilizing a front frame assembly pivotably connected to a mounting frame assembly which mounts the implement; a frame mover mechanism that lifts the front frame and mounting frame; a middle frame which connects the cab, frame mover mechanism and related components; and a rear frame which attaches rear wheels, caster wheels, engine, etc. The front wheels can turn one hundred and eighty degrees and the tractor can easily interchange consumables via a carriage system that allows simple loading and unloading of tanks, etc.
