  • Patent number: 11950536
    Abstract: A control lever of a working machine having a main operating frequency includes, a tube having a mass and a length extending from a first end to a second end. The tube defines a lumen extending from the second open end towards the first end of the tube. The control lever includes a rod having a predetermined mass and a length extending from a first end to a second end. The rod is fixed to the tube and is disposed in the lumen at a predetermined position with respect to the second end of the tube. In embodiments, the mass of the rod is determined based at least on the mass of the tube and the main operating frequency of the working machine, and the control lever has a natural frequency that is less than the main operating frequency of the working machine.

  • Patent number: 10933920
    Abstract: A work vehicle including: a vehicle body frame; a prime mover part located on a front or rear part of the vehicle body frame; a bonnet configured to open and close by swinging, and covering the prime mover part; and an assist unit configured to assist the bonnet to operate to open. A lateral end portion of the vehicle body frame is provided with a first linkage part with which the assist unit is linked. A lateral end portion of a lower end part of the bonnet, which is located closer to an end cover than the first linkage part is, is provided with a second linkage part with which the assist unit is linked. The assist unit is provided with an expansion/contraction mechanism biased so as to expand, and is located laterally outside the prime mover part and spans the first linkage part and the second linkage part.

  • 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.
