Claims (1)
- 走行機体に搭載されたエンジンからの動力を変速する無段変速機と、前記無段変速機の変速比を変更する主変速操作具と、前記無段変速機からの変速駆動出力を伝達する多段変速用の副変速機構と、前記副変速機構の変速比を変更する副変速操作具とを備えてなる作業車両の走行装置において、
前記主変速操作具の操作位置を検出する主変速センサと、前記無段変速機の変速駆動出力回転数を検出する変速出力部回転センサと、前記副変速操作具の操作位置を検出する副変速センサとを備え、
前記主変速操作具の中立操作によって、前記無段変速機からの主変速出力を車速零にし、
前記主変速操作具の最低車速操作によって決定される前記無段変速機からの最低主変速出力を、前記副変速操作具の変速段操作が高速段側のものほど速くし、
更に、前記副変速操作具の変速段操作が低速段側の状態で、前記主変速操作具の最高車速操作によって決定される前記無段変速機からの最高主変速出力よりも、前記副変速操作具の変速段操作が高速段側の状態で、前記主変速操作具の最低車速操作によって決定される前記無段変速機からの最低主変速出力を速くするように構成している、
作業車両の走行装置。
