An on-board electronics system of an aerial work platform moves the wheels between a retracted and extended position by pivoting a respective arm. The method comprises the following successive steps: a) orienting each wheel tangentially to the pivoting path of the corresponding arm, b) moving the wheel by pivotally actuating the corresponding arm, and c) reorienting the wheel so as to enable another translation of the aerial work platform. The steps are performed in different orders between the wheels so that at any time at least one of the following conditions is complied with: —the brake system of at least one wheel is active, —at least one wheel is rotated by a motorised drive, —the orientation of the wheels relative to one another prevents any translation of the aerial work platform (1) on the ground as a result of gravitational force.

A replacement tailgate for the purpose of elongating the pick up truck may be installed on a truck bed wherein the replacement tailgate can be unfolded in order to elongate a length of the truck bed. The replacement tailgate may have front and rear shells that are used to support objects placed in the truck bed as well as act as the new tailgate when the truck bed length is elongated. Various panels may be unfolded in order to trap objects within the truck bed when the replacement tailgate is unfolded in order to elongate the truck bed length.

Track systems for traction of a vehicle in which a spacing of laterally-adjacent ones of the track systems in a widthwise direction of the vehicle is adjustable. This may facilitate use of the vehicle in different conditions (e.g., in different field configurations, such as in different configurations of row crops, where the vehicle is an agricultural vehicle). For instance, the spacing of the laterally-adjacent ones of the track systems may be adjustable while the laterally-adjacent ones of the track systems are connected to a power train of the vehicle and/or without requiring use of additional parts (e.g. spacers).

A riding lawn mower having an adjustable cutting width has at least one front wheel, a plurality of rear wheels, a frame extending from the at least one front wheel to the plurality of rear wheels and a plurality of cutting decks, each cutting deck comprising a cutting blade. A motor is supported by the frame and configured to drive the cutting blades of the cutting decks. A support configured to couple the cutting decks to the frame. The support is configured to extend at least one of the cutting decks laterally from beneath the frame to adjust a cutting width provided by the blades.

This adjustable length cart frame design is for a powered cart, similar to a golf cart.

In its compacted mode, the cart is short enough be loaded in the bed of most pickup trucks or a small trailer.

In its expanded mode it can provide seating for multiple passengers and/or cargo carrying. The sliding is accomplished by having two bars or tubes that slide through larger tubes mounted on each half of the cart frame. A tracking bar keeps the bars synchronized. Locking pins hold the bars in either expanded or contracted position. An optional locking bar can be used for locking in the expanded position.

Power to expand and contract could be provided by, but not limited to; cable winch, screw jack, hydraulic ram(s) and gear drive(s).

A system and method for controlling a vehicle, where the system includes independent driving modules each including a connection device having a rotation center spaced apart from a driving shaft in a forward/rearward direction and configured to connect the wheel and a vehicle body to move the wheel in the forward/rearward or an upward/downward direction, a shock absorber extending in a longitudinal direction and configured to contract or stretch, to connect the vehicle body and the connection device, and to restrict an upward/downward movement of the connection device, and a driving device configured to rotate the wheel, a road surface detector configured to detect a height displacement or a state of a road, and a controller configured to control velocities of the front and rear wheels of the independent driving modules, and to change a height of the vehicle based on the height displacement or the state of the road.
