To enable a tractor, circulating in the same direction, to tow a head carriage even in case of disposing a plurality of carriages in series on the same endless travel path without providing special equipment.

Tractor width and height are so set that longitudinal projection shape formed of a body and traveling wheels can pass carriage under-space, partitioned by both width direction side wheels of carriages 51,... and the lower faces of the carriages, along a travel path. A tractor is provided with a front carriage detecting means 3 for detecting the presence of the front carriage 51,..., a traction pin 4 protruded/retreated vertically so as to change its position between a connecting position and a retreat position, a changing motor for driving to change the position of the traction pin 4, and a traveling motor. When the front carriage detecting means 3 detects the presence of the front carriage, the traveling motor is once stopped only for the set time, and the traction pin 4 is changed into the retreat position from the connecting position. After the lapse of the first set time, the tractor is made travel again, and after the lapse of the second set time from the stop time, the traction pin 4 is restored into the connecting position to connect the tractor to the front carriage.
