  • Publication number: 20230392540
    Abstract: A work vehicle includes a diesel engine, a heater to heat a gas to be supplied to a combustion chamber of the diesel engine, and a controller to execute an afterglow routine to cause the heater to operate. The controller is configured or programmed to execute the afterglow routine in response to the diesel engine being started, an elapse of a predetermined stop time since an end of a previous execution of the afterglow routine, and the work vehicle being in a warming-up state.

  • Patent number: 7404341
    Abstract: A transmission system for transmitting power through a traveling transmission line and also through a PTO transmission line is disclosed. The system includes a clutch housing and a base transmission case connected via a housing frame. The base transmission case includes a front end opening and a rear end opening. A differential case is connected to the rear end opening. The front end opening is selectively connected with either a gear change speed case having a gear change speed mechanism or an HST case having an HST mechanism. When the gear change speed mechanism is selectively used, a PTO power output portion communicates with the PTO transmission line and a traveling power output portion communicates with the traveling transmission line. When the HST mechanism is selectively used, a pump shaft communicates with the PTO transmission line and a motor shaft communicates with the traveling transmission line.

  • Publication number: 20050204843
    Abstract: A transmission system for a tractor, adapted for transmitting power of an engine to axles through a traveling transmission line and also to an externally mounted utility implement through a PTO transmission line. The system includes a clutch housing disposed rearwardly of the engine, a base transmission case disposed and spaced rearwardly of the clutch housing, the clutch housing and the base transmission case being connected together via a housing frame. The base transmission case includes an intermediate partitioning wall for partitioning an inner space of the case in a fore and aft direction to create a front space having a front end opening and a rear space having a rear end opening. A differential case is connected to the rear end opening of the base transmission case. The front space includes a receiving portion for the traveling transmission line and a receiving portion for the PTO transmission line, the traveling and PTO transmission lines being disposed parallel with each other.
