  "textContent": "Disclosed is a transmission apparatus for a tractor which is operable to transmit a forward drive force in a wide speed changing range to the traveling device and which is operable also to transmit a reverse drive force to the traveling device in an inexpensive manner and with good transmission efficiency. A planetary transmission section (30) is configured to output the forward drive force in whichever case a hydrostatic stepless speed changing section (11) is speed-changed to a forward rotation speed change state or a reverse rotation speed change state. A low speed transmission clutch (45) couples a low speed side speed changing gear (41), meshed with a low speed side output gear (31) of the planetary transmission section (30), to a counter shaft (44) to be rotatable therewith. A high speed transmission clutch (46) couples a high speed side speed changing gear (42), meshed with a high speed side output gear (32) of the planetary transmission section (30), to the counter shaft (44) to be rotatable therewith. An output shaft gear (48) is meshed with a counter gear (47) supported on the counter shaft (44) to be rotatable therewith. A reverse transmission clutch (52) couples a reverse transmission gear (51), meshed with the high speed side output gear (31), to an output shaft (43) to be rotatable therewith.",
