Why tractor front wheel is small

The rear tires have so much traction with the tread patterns that it lifts the front of the tractors. This usually happens when a heavy load is being pulled.

Traction makes the rear end of the tractor stationary and the front end lift. Unlike cars, tractors are designed to work on uneven surfaces. Therefore maintaining the center of gravity is crucial. The size of the rear wheels is almost double that of the front wheels.

Tractors remain stable in loose and mussy conditions without tipping over. Tractors with the same size rear and front wheels are usually 4 wheel drive utility vehicles. These tractors work in extreme environments like on narrow hilly roads, surfaces covered with snow and rocks.

Same size wheels and tires help to increase the mass of the machine to increase the traction. Pressure is force times area, the enormous force generated from the engine is uniformly spread on a larger surface area using the wider tires.

Tractors have wide rear tires to spread the pressure. Tractors not only use the surface to move on, but they also work on the farm surfaces. A large base helps in avoiding the creation of a steeper impression in the soil. To reduce crop destruction and soil compression, small tires with narrow wheels became a technical factor. In large farms, sowing is done in a straight line, sometimes for many hectares. Without any fixed path, this can be a tricky proposition.

Front wheels help the operators or drivers move in a straight line. The tractors often have front wheels at an angle to minimize the steering. This feature was prominent in the tractors of the past. This was the time when tractors were not equipped with power steering. It was tedious to steer these giants. With the angled tires, the forward motion was smooth. The driver had to rotate the steering wheel a little to make big turns. In the early evolutionary phase, some tractors had three wheels, 2 rare and one front wheel.

Another reason why this is common is for ground clearance. This one's pretty simple. The further off of the ground the non functional bottom of the vehicle is, the larger objects it will be able to pass over without contact and damage.

And yet another reason for this, is incredible toque put out by a tractors transmission. You may have noticed, your little four door sedan can be more powerful than a tractor, or you may be surprised about this. It is common to think that the higher horsepower you have, the more your vehicle will be able to pull. This is not always the case. For example, my school owns a small You may be wondering how so little power, can mean such high results.

Well, mostly due to the low gear ratios of the tractors transmission, this is possible. As some of you may know, the larger the diameter of a circle, or the higher the circumference, the larger amount of torque the object will have due. This is due to a simple law of physics this is also why car differentials were invented.

I'll put this into terms that are easy to understand. When you spin a circle, or any shape for that matter let's say a ruler on the end of a pencil "helicopter" style , the outside edges of that object have to spin fast than the inside of the object to keep up with the inside. The outside edge has a farther distance than the inside to cover in the same amount of time, making it spin faster and with more power.

Transmissions use the same excact principle. The larger the gear is, the higher the torque. This means, in first gear in your car, you are using the largest gear in the transmission. Wheels work the same way. Another reason for the rear wheels being much larger than the front wheels on the common depiction of a tractor.

Not all of them is the fact that they help with weight distribution. Commonly, the engine in a tractor will be located in the front, and anyone who's tried to pick up an engine will know, they could definitely shed a few pounds. Now what happens when a baby is sitting on one end of a seesaw and a full grown obese american plops on the other side? You guessed it, bye bye baby astronaut.

In other terms, the front of the tractor may tip over. I don't see this mentioned, but it might be as I didn't read every sentence posted here: Rear tires on tractors are generally filled with liquid, and they are very heavy. This adds to the traction, but also to the weight on the rear wheels.

Thus they need to be wider, and being larger, as mentioned above, they present a greater length in contact with the ground as well. Tires designed for multiple uses and turf tend to be wider than ag tires because they need to "float" over grass with less digging in. Also rear tires can carry heavy implement loads, often as great or greater than the weight of the tractor itself. So, add it all up and you need a larger tire for weight, traction and load capacity as well.

My little tractor can lift pounds with the loader but about pounds of implement on the 3 pint hitch. Put that implement 24 inches behind the tractor and the leverage created is substantial. So, say, that pounds becomes pounds on the tires due to leverage. Due to the bigger rear wheels, the driver seat set at a higher position that provides good visibility and corners of the field ploughs. It makes farming work easy and productive. That is why tractor wheels are big.

As we know, large tyres come at a higher price, and the small tyres price is low. So, the replacement of small tyres is easy and cheaper. That is why tractors have big wheels. The heavy rear wheels provide a proper weight distribution while the tractor pulls any weight. That is why the tractor rear wheel is big. The driving axle settled higher above the ground indicates the tractor can pull more weight without the front wheel rising. It works like a lever where the twice height means twice pulling force.

The engine of a tractor is very heavy and powerful, located at the front of a tractor. So, the large wheels at the rear distribute the weight more evenly to counter a heavy front. Mainly tractors are used to prepare the field before sowing seeds, and they also maintain healthy plants. A farmer needs to care for the soil as well as crops. The bigger rear tyres have a much larger surface area, the weight of the tractor is distributed across a large area, so the tyres do not compress the soil quality as much, which is why the rear wheels of the tractor are bigger.

A tractor engine is very heavy and is located at the front of a tractor, potentially causing it to tip nose first. Larger heavier wheels at the rear of the tractor distribute this weight more evenly to counter a heavy front.

Tractors are used to prepare the ground before the seeds are sowed, as well as throughout the crops life to maintain healthy plants. A farmer needs to look after the soil as well as the crop.
