<p>A work vehicle (10) is disclosed. The work vehicle (10) including a chassis (12), a ground engaging mechanism (14) configured to support and propel the chassis (12), an engine (22) coupled to the ground engaging mechanism (14) to power the ground engaging mechanism (14), a work tool (18) supported by the chassis (12) to move material and a control system (24, 26) for adjusting a speed of the engine (22) of the work vehicle (10). To improve fuel consumption and wear conditions of the engine (22) it is proposed that the control system (24, 26) having an idle function configured to operate the engine (22) in a first idle state (40) for a first period of time (42) wherein an idle timer controlling the first period of time (42), and to operate the engine (22) in a second idle state (44) after the first period of time (42) expires, the engine (22) operating at a lower speed in the second idle state (44) than in the first idle state (40). Furthermore a method for automatically adjusting a speed of an engine (22) of the work vehicle (10) is proposed.</p> |
