As is well known in the art, turf mowers are often used for maintenance in varying topographical environments, such as field mowing, lawn mowing, golf course maintenance, and the like. These turf mowers are typically riding-type and include at least one mowing deck suspended for the vehicle frame. The mowing deck is movable between a raised non-cutting position, often used during vehicle travel from one cutting area to another to avoid hitting obstacles such as curbs and stones, and a lowered cutting position. Conventional mowing decks often employ decks wheels and/or rollers which serve to support the mowing deck on the ground in this lowered cutting position. Consequently, the weight of the mowing deck is carried by these deck wheels and/or rollers. This arrangement ensures that a constant and consistent cut height is maintain during the cutting operation.
Many riding turf mowers are equipped with mechanisms for positioning the mowing deck to a desired cutting height. Most of these mechanisms consist of linkages interconnecting the mowing deck and a lever, which is directly controlled by a hydraulic or electric actuation system. The actuation system is often controlled by the operator's hand or foot.
Operators of these turf mowers must often traverse slippery and/or inclined terrain during the cutting operation, when the mowing deck is in the lowered cutting position. Depending upon the slope of the grade or the condition of the turf, many known turf mowers exhibit loss of traction in the drive wheel in such situations, which complicate or even prevent cutting of some difficult areas.
Accordingly, there exists a need in the relevant art to provide a turf mower having improved traction performance. Furthermore, there exists a need in the relevant art to provide a traction enhancing system for a turf mower to improve operation thereof. Still further, there exists a need in the relevant art to provide a turf mower that is capable of overcoming the disadvantages of the prior art.
