why the backwheel of tractor is bigger than frontwheel?

Answer Posted / bishu

1)Since driving wheel in Tractor is in rear wheel and driven
wheel is in front. If driving wheel(i.e,rear wheel) rotate
for one time then driven wheel(i.e,front wheel) rotate more
than one time because of it smaller size.. As the rotation
increases in front and rotation decreases in rear lead to
more velocity ratio....... TO INCREASE VELOCITY RATIO IN
TRACTOR BACKWHEEL IS BIGGER THEN FRONTWHEEL
