<p>PURPOSE:To reduce the weight and size, by securing a reinforcement frame between both the sides of the tractor body holding a clutch housing and an engine eccentrically located at one side and by coupling front wheel supports to the reinforcement frame. CONSTITUTION:The reinforcement frame 5 is secured astride the engine 1 and the clutch housing 2 at one side of an assembly 4 consisting of the engine 1, the clutch housing and an transmission 3 coupled to one another. A holder 8 for holding a pair of steering front wheels 7, 7' is coupled to the front end of the reinforcement frame 5 by center pins 9 of the supports 11 so that the holder 8 can swing around a rear-to-front axis. The reaction of the gound concentrated to the supports 11 through the front wheels 7, 7' is efficiently dispersed to both the side of the clutch housing 2 and the engine 1 through the reinforcement frame 5.</p> |
