Title:
APPARATUS FOR VARYING TRACK WIDTH OF AGRICULTURAL TRACTOR
Document Type and Number:
WIPO Patent Application WO/1984/003476
Kind Code:
A1
Abstract:
A drum-shaped hub (10) is attached to an end of an axle A of a tractor, and an outer ring (17) which retains a tire is screwed onto a drum portion of the hub. The outer ring (17) is located at a predetermined position on the hub drum portion and is then secured by fixing devices (10a, 15, 19). If the axle A of the tractor is rotated under the state in which the fixing devices are removed and the outer ring (17) is screwed onto the hub drum portion, the position of the outer ring (17) along the hub drum portion changes, thereby enabling an easy adjustment of the track width.
