Definitions

  • Embodiments relate generally to utility vehicles, and, more particularly to a foot controlled stand up zero turn radius utility vehicle.
  • Some conventional utility vehicles may not be suitable for certain applications such as operating handheld equipment (e.g., line trimmer, edger, hedge trimmer, etc.) due to a need for some conventional vehicles to be operated by hand controls and/or due to the front of some conventional vehicles (e.g., a mower) having a platform or deck (e.g., for a mower blade or other equipment) extending out from the conventional vehicle such that operating handheld equipment to contact the ground (e.g., a line trimmer or edger) may be difficult or cumbersome.
  • a platform or deck e.g., for a mower blade or other equipment
  • One or more embodiments were conceived in light of the above-mentioned limitations or problems, among other things.
  • Some implementations can include a zero turn radius (each drive wheel is independently controlled) utility vehicle that is operated in a standing position (“stand up”) by an operator using foot controls provided on the utility vehicle. Accordingly, the operator’s hands are free to operate handheld equipment (e.g., a line trimmer, edger, blower, etc.) while the operator controls the utility vehicle via the foot controls.

Abstract

Conformément à certaines mises en œuvre, la présente invention concerne un véhicule utilitaire à rayon de braquage nul qui est actionné dans une position debout par un opérateur à l'aide de commandes au pied disposées sur le véhicule utilitaire. En conséquence, les mains de l'opérateur sont libres pour actionner un équipement portatif (par exemple, un coupe-herbe, un coupe-bordure, une souffleuse, etc.) tandis que l'opérateur commande le véhicule utilitaire par l'intermédiaire des commandes au pied. En outre, le véhicule utilitaire peut avoir une seule troisième roue (et aucun châssis de tondeuse ou autre châssis ou protubérance) s'étendant à partir de l'avant du châssis de véhicule de façon à réduire au minimum toute protubérance vers l'avant du véhicule, ce qui peut permettre à l'opérateur de travailler sur le sol devant le véhicule utilitaire en utilisant un équipement portatif sans interférence provenant d'un châssis de tondeuse, tout en restant dans une position debout sur le véhicule utilitaire et en étant capable de commander le véhicule utilitaire (par l'intermédiaire de commandes au pied) et d'effectuer un travail au moyen d'un équipement portatif, simultanément.
