Tractor, Travel Transmission Device For Tractor, And Tractor Equipped With Travel Transmission Device For Tractor
Abstract: In order to increase the overall reduction ratio of a creep transmission while preventing an increase in the size of a transmission case in a travel transmission device for a tractor in which a creep transmission device is accommodated in a transmission case, a creep transmission device 60 is provided with: a first transmission gear 66 provided on an output shaft gear 54b of a gear transmission 40; a first reduction gear 62 supported on a relay shaft 61 so as to be capable of relative rotation in a state of being engaged with the first transmission gear 66; a second transmission gear 67 provided on the first reduction gear 62; a second reduction gear 63 supported on an output shaft 43 of the gear transmission 40 so as to be capable of relative rotation in a state of being engaged with the second transmission gear 67; a third transmission gear 68 provided on the second reduction gear 63; a third reduction gear 64 supported on the relay shaft 61 so as to be incapable of relative rotation in a state of being engaged with the third transmission gear 68; and a reduction gear pair 65 that is provided across the relay shaft 61 and the output shaft 43, and that reduces and then transmits the power of the relay shaft 61 to the output shaft 43.
