摘要： A travel speed change apparatus for a farm vehicle in which a first speed change mechanism and a second speed change mechanism coact to change the travelling speed. The first and second speed change mechanisms are operable by manipulating a single hand lever movable in two different directions and not two independent levers. This single lever is adapted to actuate the first and second speed change mechanisms by moving in the same direction.

摘要： A four wheel steering tractor comprising a grass cutting system vertically movably mounted in a lower space of the tractor between front and rear wheels. The grass cutting system carries gauge wheels disposed at opposite lateral sides in rear regions thereof. An interlocking structure between a steering wheel and the front and rear wheels includes a front drag link extending from a pitman arm toward the left (or right) front wheel, and a rear drag link extending from the pitman arm toward the right (or left) rear wheel. This interlocking structure places the center of tractor turning approximately on a straight line extending through the gauge wheels and adjacent one of the gauge wheels.

摘要： A drive transmission structure for a tractor comprising a belt drive system for transmitting power from an engine output shaft to a transmission having a brake mechanism. The belt drive system includes a belt type stepless change speed mechanism having a split pulley assembly and a swing device for swinging the split pulley assembly toward the engine output shaft and the transmission, a first belt for transmitting the power from the engine output shaft to the split pulley assembly, and a second belt for transmitting the power from the split pulley assembly to the transmission. The pulley assembly defines two split pulley sections for engaging the first and second belts, respectively. A control device is provided to change power transmission ratios by actuating the swing device. Further, a tension pulley type clutch mechanism is provided to act on the first belt or the second belt. The brake mechanism and the tension pulley type clutch mechanism are controlled by the clutch and brake control mechanism.

摘要： A change speed apparatus for a tractor comprising a combination of frictional stepless change speed means and planetary reduction means. A large diameter gear is used to drive the frictional stepless change speed means by means of engine output, and the frictional stepless change speed means includes a large diameter driven disc which engages an outer periphery of an internal gear of the planetary reduction means to be axially movable but not rotatable relative to the internal gear. The planetary reduction means is located in a space defined by the large diameter gear and the frictional stepless change speed means.
