  • Patent number: 10377219
    Abstract: A tractor includes an engine that is mounted on a vehicle body frame, a hood that houses the engine and is configured to pivot about a front pivot in a top-bottom direction between a closed position at which the hood covers the engine, and an open position at which the hood exposes the engine, a mounting rubber that is provided between the engine and the vehicle body frame to support the engine in an anti-vibration manner, and a hood stay that supports the hood such that the hood is pivotable up/down about the front pivot. The hood stay includes an abutting-target portion against which the engine can abut from a rear side, to prevent the engine from swinging forward in a front-rear direction of the vehicle body.

  • Patent number: 10315534
    Abstract: 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.

  • Publication number: 20140211440
    Abstract: Provided is technology that stably fixes a plurality of harnesses all at once, without using a wire holder. A line-shaping section 30 for routing harnesses 99 is created in a front cabinet forming section 20. The line-shaping section 30 comprises two ribs 40 separated by a prescribed distance and a hook 50 positioned in the center thereof and created so as to cover from the top, when viewed from the side surface. The harnesses 99 held by the ribs 40 and the hook are prevented from being displaced outside, by a hook locking section 54. In addition, routing work for the harnesses 99 is able to be performed smoothly since a sloping surface (a guide section 56) is created in a tip part of the hook locking section 54.
