Answer / sridhar

Reasons for Having so is
1)Tractor needs Tractive force with low speeds which is
meant for soft terrains.
2)Since the Coefficient of friction between tyre and
surface contact is low in order to overcome this,tractor
produces high tractive force with low speed.
3)For steering stability and power consumption the front
wheel is designed small size.
4)Torque=Force * Distance(T=F*R) by keeping Force constant
and increasing Distance between Wheel axis and force
applied will increase torque which is desired

Answer / thirumurugan_p

I think most of vehicles the
power give in the bigger
wheel sides bcoz then only
we can easily turn vehicle any
direction without problems
but if give the power to small
wheels not possible to
turning and running as our
required

Answer / murugan.m

REASON1. Main purpuse is turn the vehile using less power it is possible for front wheels are smaller than large.
REASON2.Implements are attach with the tractor rear end only

Answer / shunty vij

front are only for steering.if they are large they require
more force to steer and rear for traction. so large size has
more torque.

Answer / arun muthu kumar

Because the back wheel has the full geared power of engine,
to pull the load in rising ground and in uneven road, also
to pull the tractor in fenders,for ploughing in field

Answer / zakir hussain

rear wheel in tractor is bigger to have more
torque /traction because bigger the dia more is the torque

Answer / abhishek

Tractor is mainly used for
pulling or traction
purpose,back wheels are
driven by engines,to pull
heavy loads it must hv
sufficient horizontal recn b/w
tyre nd ground which wud
be possible wid large dia
wheel.

Answer / sathishkumar

In the tractor, load acting on front wheel is heavy due to
engine and other parts.inorder give counter weight, the
rear wheel design as bigger.
And also- If we consider tractor application,while
ploughing in field- agriculture wheels should not get
locked in field. hence rear wheel is designed as bigger

Answer / s.n.rao

Be.cause front wheel suitable to all areas ie' up &
down ,loose soil & watering areas easy forward moveing,&
back side wheel hevy force applid ther for back wheel
bigger tyre used,

Answer / akhil

because all work is done by tractor from behind like the
field growing & big tyre is at rearend for the balancing &
small tyre in front of the Driver because easy for the
driver to drive it
