Abstract
A transmission for a tractor comprises a transmission case having an opening that opens to exterior of the transmission case and a speed change device that is housed in the transmission case. The transmission also includes a cover removably attached to the transmission case for closing the opening of the transmission, a main speed change shift fork supported by the cover and capable of engaging with and moving a main speed change shifter, and a sub speed change shift fork supported by the cover and capable of engaging with and moving a sub speed change shifter. The cover is capable of mounting a creep speed change device having a creep speed position.

A transmission for a tractor comprising:
- a transmission case having an opening that opens to exterior of the transmission case;
- a speed change device that is housed in the transmission case and that transmits driving power from an engine of the tractor to a driven wheel, the speed change device includes:
- a main speed change device capable of changing speed of driving power form the engine to a plurality of speeds;
- a main speed change shifter that causes the main speed change device to change speed;
- a sub speed change device that further changes speed of driving power whose speed was changed by the main speed change device;
- a sub speed change shifter that causes the sub speed change device to change speed;
- a cover removably attached to the transmission case for closing the opening of the transmission, the cover being capable of mounting a creep speed change device having a creep speed position;
- a main speed change shift fork supported by the cover and capable of engaging with and moving the main speed change shifter;
- a sub speed change shift fork supported by the cover and capable of engaging with and moving the sub speed change shifter.
