A combine harvester with a variable length wheelbase. For example, a combine harvester may have a chassis defining a forward end and a rear end, a feeder house at the forward end of the chassis, a first set of ground-engaging elements supporting the forward end of the chassis, and a second set of ground-engaging elements supporting the rear end of the chassis. The second set of ground-engaging elements are configured to move forward and rearward relative to the chassis.

An agricultural harvester, such as a combine harvester, which has an auxiliary axle assembly for support of the feeder house of the harvester. The auxiliary axle assembly can be provided in a retracted position when in a field mode, and can be locked in an extended position when in a road mode, where a wheel of the assembly contacts the ground. When in the locked, extended position, the auxiliary axle assembly supports substantially all of the weight of the feeder house and any attached implements, allowing the feeder house to pivot relative to the main chassis of the harvester.

An autonomous robotic lawnmower (1) is disclosed comprising a driving unit (3) comprising one or more drive wheels (5), and a cutting unit (7) configured to cut grass during operation of the lawnmower (1). The cutting unit (7) comprises one or more support wheels (9) configured to support the cutting unit (7) by abutting against a ground surface (11) during operation of the lawnmower (1). The cutting unit (7) is movably arranged relative to the driving unit (3). The lawnmower (1) comprises a suspension assembly (13, 13′) configured to progressively limit movement between the cutting unit (7) and the driving unit (3) during operation of the lawnmower (1).

An agricultural header comprises a first frame, a second frame, an endless side draper belt supported by the first frame, an endless center draper belt positioned in register with the side draper belt to receive cut crop laterally therefrom, an inter-frame flexible seal coupled to the first frame and the second frame. The first frame is coupled for movement relative to the second frame. The flexible seal underlies the side draper belt to receive cut crop that falls from the side draper belt and is arranged relative to the center draper belt to guide fallen crop toward the center draper belt. The flexible seal is configured to flex to accommodate movement of the first frame relative to the second frame.

Front and rear independent suspension mechanisms accommodating an increased range of motion to better absorb shock originating at the wheels of a riding mower to insulate the operator and reduce stress on the mower chassis and other mechanical components. The front suspension can include a front axle with pivot pockets allowing 360 degree rotation of pivots engaged within the pockets, thereby providing a greater range of absorption of shock entering the front axle at varying angles. The rear suspension can include a vertically pivoting transmission platform, providing for controlled vertical motion in the transmission while the transmission is powered by an engine by way of a belt assembly.
