摘要： A drive system for a work vehicle comprises a control unit adapted to: monitor output of a speed ratio setting input device for a speed ratio setting request signal and output of a drive-request input device for a FWD-only request signal, determine from the speed ratio setting request signal if a requested speed ratio setting represented thereby is one of at least one predetermined speed ratio setting among a plurality of speed ratio settings possible for the work vehicle upon receipt of the FWD-only request signal, and, if so, output at least one control signal engaging a FWD-only mode enabling FWD operation of the work vehicle but disabling RWD operation of the work vehicle. An associated method is disclosed.

摘要： A boom position detecting device that detects a boom angle on a work vehicle for a boom that rotates about a pivot. The device includes a boom angle follower and positional sensor. The boom angle follower includes a spring and a follower arm arranged such that the spring biases the follower arm against a surface of the boom and keeps the follower arm in contact with the boom throughout a rotational movement of the boom about the pivot. The positional sensor is physically connected to the boom angle follower and detects at least one boom angle.
