Tractors have Bigger Rear Wheels and Smaller Front Wheels. Why?

Tractors have a different types of work to undertake in the fields. Tires of different sizes in the first instance make right contact with the ground. In the field, tractor can pull heavy weight and gives better digging experience in the rough and tough fields. Different type of tires prevent from sinking, balance weight, maintain stability and the maintain power. The reasons tractors have different wheels are:

Grip On The Ground: Bigger tires as rear wheels work perfectly on muddy fields and avoid slipping. Secondly the broad tires balances the weight and also covers the larger surface areas to distribute the weight equally. Pulling heavy  loads behind the tractor also produces great pressure on the rear wheels and bigger rear wheels do the gripping job flawlessly.

Better Forward Visibility: Small size of wheels in the front provide better view on the ground. It is much easier to see everything as the driver seat is set at higher position which keeps an eye both on rear and front wheels. Driving seat at higher elevation in rear wheel tractor makes farming easy as the driver can easily see the corners of the fields and roads and becomes easier to plough the land with better forward visibility.

Handling: Smaller wheels at the front offer better handling feature to the tractor by the driver. Driver can easily turn through sharp corners in the field with small front wheels in the front.

These are the tops reasons tractors have bigger rear wheels and smaller front wheels. Different size of wheels distributes the weight equally on all the tires.
