PROBLEM TO BE SOLVED: To provide a three-wheeled crop managing machine whose tread width can be adjusted and which can simplify a driving force-transmitting means from an engine to driving wheels. SOLUTION: This three-wheeled crop managing machine 10 whose rear wheels 18L, 18R are attached to the machine frame in a state capable of being swung in the machine body width direction and whose rear wheel tread W can be adjusted in response to a space between ridges is characterized by changing the output of an engine 21 loaded on the machine frame 11 with hydraulic transmissions 22L, 22R, supplying the changed output to the rear wheels 18L, 18R, and disposing the hydraulic transmissions 22L, 22R so that the input shafts 69L, 69R of the hydraulic transmissions 22L, 22R pass through the swinging points 76L, 76R of the rear wheels 18L, 18R and that the hydraulic transmissions 22L, 22R are swung together with the rear wheels 18L, 18R.
