A work vehicle includes a vehicle body, an engine mounted on the vehicle body, a hood covering the engine, a driver's seat on one side with respect to the hood in a front-rear direction of the vehicle body, a step extending under the driver's seat and having a width wider than a lateral width of the hood in a left-right direction of the vehicle body, and a ROPS including left and right columns respectively located on two lateral sides of the vehicle body between a front end of the hood and a front end of the driver's seat, the left and right columns including upper end portions coupled to each other. Each of the columns is located within a range extending from a laterally outermost end of the hood and to a laterally outermost end of the step in the left-right direction of the vehicle body.

A universal mount for installing a canopy onto tractor and mower ROPS (roll bars). The ROPS may have left and right downward extensions and a bridging element between the left and right downward extensions. The universal mount includes a clamp to secure the universal mount onto a ROPS, a crossbar attached to the clamp extending parallel to the bridging element, and plates on each opposed end of the crossbar. Each plate has at least one slot adapted to receive a fastener. The universal mount can be clamped to a ROPS with the canopy fastened by aligning holes on the canopy with the slots and passing fasteners through. The canopy attitude can be adjusted to a desired orientation by positioning fasteners at a selected position in the slots.

A work vehicle includes a vehicle body, a positioning unit that detects a position of the vehicle body based on a signal sent from a positioning satellite, a support configuration portion installed on the vehicle body, an installing stay to which the positioning unit is fixed, and a base stay fixed to the support configuration portion. One of the installing stay and the base stay has a protruding piece portion. Another of the installing stay and the base stay has a hole portion into and with which the protruding piece portion is inserted and engaged.

A work vehicle includes an operator cabin, a transmission-supporting frame, and a mounting assembly. The mounting assembly includes a first mount configured to couple to the operator cabin, and a second mount configured to couple to the transmission-supporting frame. The first mount includes a first plate, and the second mount includes a second plate. The first plate and the second plate are coupled to one another at an interface, and at least one of the first plate and the second plate are configured to deform proximate to the interface to separate from one another when under tension during a roll-over event.

A vehicle cab assembly includes an internal frame including multiple rigid members that are secured rigidly one to another. The vehicle cab assembly also includes multiple cladding panels that obscure the internal frame and enclose it uninterruptedly in at least one plane. The cladding panels are supported on an exterior of the internal frame and define mutually abutting panel edges along which the cladding panels are sealed one to another to define weather-proof joints of the vehicle cab assembly.

A zero turning radius mower radiator mounting structure having inclined deflectors extending upwardly from the radiator. The inclined deflectors slide on a cross member extending horizontally across the roll over protection system if the mower is in a rollover position. The inclined deflectors push the radiator rearwardly from the roll over protection system and disengage the radiator from first and second pairs of isolators.

Provided is a work vehicle having a rollover protection structure (ROPS) around a driver's seat which is switchable between a front seating posture and a rear seating posture. A locking mechanism locks the driver's seat to the rear seating posture. The locking mechanism includes a hook provided on the driver's seat side, a hook rod disposed between a left strut and a right strut and engageable with the hook when the driver's seat is switched to the rear seating posture, and a rod bracket for supporting the hook rod. The rod bracket is provided separately from the left strut and the right strut.

Provided is a work vehicle in which a seat support frame that supports a driver seat is equipped on a vehicle body frame, the vehicle body frame includes: a front portion vehicle frame at which a floor surface of a driving portion is provided; and a rear portion vehicle frame disposed at a position higher than the floor surface of the driving portion and rearward of the front portion vehicle frame. An engine is equipped below the rear portion vehicle frame, a battery that supplies power to an electric motor is equipped above the front portion vehicle frame and below the seat support frame, and a frame portion of the seat support frame that exists above the battery at a position opposing the battery is configured to be detachable from another frame portion that is fixed to the vehicle body frame.

Vehicle drive and control systems are disclosed. A utility vehicle includes a first electric drive motor configured to drive a first traction wheel, a second electric drive motor configured to drive the a traction wheel, a steering wheel configured to receive a first user input, one or more pedals configured to receive a second user input, a steering input sensor, and a drive input sensor. The steering input sensor is configured transmit a steering input signal that corresponds with a steering input position. The drive input sensor is configured to transmit a drive input signal that corresponds with a drive input position. A plurality of controllers are configured to collectively generate, based on the steering input signal and the drive input signal, a first drive signal to drive the first electric drive motor and a second drive signal to drive the second electric drive motor.
