<p>An extension axle of a movable agricultural machine is provided to prevent drooping by modifying the extension axle for widening a wheel track of the agricultural machine, to prevent banks from being injured and a clutch from being inhibited, and to thereby improve working efficiency and quality of the agricultural machine. An extension axle(40) of a movable agricultural machine, which is combined with a vehicle axle(36) and protruded outward without difference to maintain a linear state with the vehicle axle without dropping/lifting a transmission and wheels, comprises a vehicle axle base(42) welded/fixed at a transmission case where the vehicle axle is protruded; a main housing(44) fixed with the vehicle axle base by a bolt; a square type vehicle axle hole(45) formed in the main housing and combined with the vehicle axle to receive the rotation force of the vehicle axle; an extension axle(46) formed circular on the outer diameter and maintained by a bearing; a hub(49) combined by a control pin(50) and formed with a connecting board(48) to mount the wheel; and plural wheel track adjusting holes(51,52,53) formed on the extension axle and the hub to be regulated according to working condition or the banks in working about the wheel track. The wheel track adjusting holes of the extension axle are adjusted of a long width by widening the interval, and the wheel track adjusting hole of the hub narrows the interval to adjust to a short width.</p> |
