WHY TRACTORS HAS NO SUSPENSION

NEED OF SUSPENSION IN TRACTOR

Tractors other heavy commercial vehicles do not have suspension because of the following reasons:

(1)While moving tractor is supposed to maintain a constant height for ploughing and digging.If there is a suspension system then it will oscillate in the direction of suspension.Thus it will be unable to maintain a constant depth.
(2)Due to Suspension offroad stability is less.
(3)While ploughing there will be load trying to make the tractor stop as its inserted in the ground. This may cause the body of the tractor to tilt backwards

  Note:  As the speed of the tractor is less and the tyres big(which absorbs more shocks),the need of suspension is felt less.
