Invented are narrow vehicles for operation on soft surfaces for agricultural use. These would enhance worker productivity and make the work more attractive. It is essential that such vehicles be simple and low cost to enable wide adaptation. Such vehicles include a frame and a wheel set that enables a low seating position for a rider. This low seat position changes requirements for stability compared to most, familiar vehicle types. The intended low speed operation further eases the requirement for stability measures. The width of the vehicle is approximately the same width as the seated rider which enables vehicle use with narrowly spaced row crops. Wide drum wheels provide the needed stability, and with large diameter the drum has maximized footprint area which minimizes penetration into the soft underlying surface, enabling high efficiency operation.
A narrow vehicle for agricultural work that includes a frame with an attached set of wheels and an attached seat for a farm worker, where base of said seat is carried low to enable said worker to ride as low to the ground as possible, where said seat enables said worker to ride facing in the direction of forward vehicle motion, where said set of wheels includes a wide wheel set that is confined within a vehicle width that is approximately that of said worker thus seated, where said wide wheel set provides maximized ground area support and provides stabilization according to width of outer edges of said wide wheel set, where said stabilization acts to prevent roll over of said narrow vehicle.
A recumbent vehicle according to the general form of a recumbent bicycle and its many mechanized and propelled variations, where said recumbent vehicle is fitted with a wide drum wheel whereby operation on soft surfaces would be enabled.
A narrow snow-mobile of width equal approximately to that of a single seated person, that is equipped with a wide wheel set of width approximately that of a single seated person, where stability is provided by said wheel set, and said wide wheel set provides a stabilizing stance that is determined by the outer edges of said wheel set.
