Abstract: In a riding-type mower, a vehicle body includes a rear portion in which a pair of right/left vehicle body frames extend in a front-rear direction relative to the vehicle body, with a gap therebetween in a lateral width direction. A mowing device is configured to discharge mown grass rearward relative to the vehicle body such that the mown grass falls onto the ground. A cover is provided in a bottom portion of the vehicle body, at a position that is rearward of the mowing device, and covers a gap between the pair of right/left vehicle body frames.

Abstract: A self-propelled vehicle includes a maneuvering unit, a drive unit including first and second drive sections, which are driven and controlled by drive wheel control commands, a drive wheel unit including left and right drive wheels driven by the first and second drive sections, respectively, at least one caster wheel which is controlled by a caster wheel control command, a bank detector for detecting a degree of bank of the vehicle and a control unit including a drive wheel control section for generating the drive wheel control commands. The control unit further includes a caster wheel control section which generates the caster wheel control command for controlling the steering angle of the caster wheel during a bank traversing travel, based on the bank degree so as to resolve a difference between a target travel and the actual travel which occurs during the bank traversing travel.

Abstract: A riding mower is provided with a front frame, a rear frame on which a drive unit is mounted, a rollover protective structure (ROPS). A first coupling part couples one front frame and one rear frame. A second coupling part couples a rear end of the front frame and a supporting column of the ROPS. A third coupling part couples the supporting column and the rear frame. The riding mower utilizes at least one triangular structural element defined in part by the first, second and third coupling parts.
