When a vehicle's transmission is in false park, it may appear to the driver that the vehicle is fully locked in "park". However, on vehicles with this defect the transmission is neither in park nor in hydraulic reverse. Instead, it is in neutral, an unstable position between the two gears. [6]
Not long after the Greens Mower was released. In 1928 Jacobsen made a notable contribution to small engines by inventing the recoil start, by 1932 all Jacobsen mowers used recoil starters. The company continued to produce mowers for estates and golf courses throughout the 1920s and 1930s, and was not damaged by the Great Depression. Knud ...
A riding mower, also known as a ride-on mower, tractor mower or lawn tractor, is a type of lawn mower on which the operator is seated, unlike mowers which are pushed or towed. Riding mowers, which sometimes resemble small tractors, are larger than push mowers and are suitable for large lawns, although commercial riding lawn mowers (such as zero ...
A Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction. It is sometimes called the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon (1923–2008), [ 1 ] who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United ...
Sensors monitor wheel speeds, and if one is rotating more than a specified number of revolutions per minute (e.g. 100) than the other (i.e. slipping) the traction control system momentarily brakes it. This transfers more power to the other wheel, [6] but still employs the open differential, which is the same as on cars without the EDL option ...
The Ragonnet power reverse, patented in 1909, was a true feedback controlled servomechanism. The power reverse amplified small motions of the reversing lever made in the locomotive cab with modest force into much larger and more forceful motions of the reach rod that controlled the engine cutoff and direction.

[1] [2] [3] They can be used on small vehicles such as ride-on lawn mowers and motorized golf carts. They also are used on heavy equipment required to operate on sites where risk of tire punctures is high. Tires composed of closed-cell polyurethane foam are also made for bicycles and wheelchairs.

A diagram of an aquaplaning tire Two vehicles aquaplaning through large puddles on the road's surface. Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs.
