Your farm specialises in field crops. For wheat, rapeseed, barley, corn or beetroot… and for your various ploughing, sowing, spraying or harvesting activities you can increase your yield by optimising your equipment and in particular your tyres, which are the sole connection between the soil and your farm machinery.
There are as many different tyre models and possibilities as there are machines and activities, so how can you find the tyre that is most suited to crop farming?
It's important to be aware that if you use the best tyres, you will see the gains on all aspects of your activity: increased traction, tasks achieved more quickly, less soil compaction, less spinning, no more adjusting pressure, less fuel consumed and higher yields.
While Radial tyres tend to dominate the tyre market, for each individual activity, there is a tyre designed specifically.
For field crop farming, choosing the right tyre casing is vitally important. There are two main categories on the farm tyre market: diagonal casing and radial casing.
The casing of each farming tyre is easy to recognise due to their distinct treads and specific characteristics.
Considering the characteristics of each casing, radial agricultural tyres are recommended for farms specialising in field crops. Distribution of pressure on the soil is perfectly spread out with a radial casing as the tread is aligned with the ground, it improves traction and improves the transmission of the tractor’s power to the ground, the flexibility of the casing makes it possible to lower the pressure for better protection of the soil structure.
This phenomenon is essentially due to repetitive activities of heavy machinery, in particular when the soil is very wet. As the tyre is the main element in direct contact with the soil, it has mechanical actions which can be more or less visible. They can result in soil compaction in your fields which directly impacts the development of the root systems and reduces your crop yield.
On farms specialising in field crops, heavier and more powerful machinery is becoming the norm. While they are very efficient in terms of production, they tend to accelerate soil compaction.
The best answer is to equip your machinery with farm tyres designed to carry the necessary load, but capable of working at low pressure. To achieve this, don’t hesitate to use farm tyres with a high surface of contact with the ground and a large volume of air to distribute the tractor’s weight across a greater area. This method reduces the pressure of contact and the impact on the soil structure, making your work more productive.
Tyre manufacturers currently sell all types of agricultural tyres in almost every size. For the same diameter, you can find different tyre widths:
Contrary to what many people think, low pressure tyres are not designed solely for harvesting machines or for farm trailers. The are increasingly used on farm tractors to remedy the problems of soil compaction and rut creation. With their increased width, this type of tyre contains a large volume of air to carry heavy loads at moderate pressure, reducing the burden applied to the soil.
Ideally, you should not be using the same tyre pressure on road and field surfaces: low pressure for field work and high pressure on the road. If you are working fields that are a good distance from each other, you have to get up and down from your cabin to adjust the pressure each time you change ground surface. The question is how to avoid this problem. There is a tyre which will allow you to continue to work with the same pressure without having to think too much about it.
With their innovative design, with low pressure VF tyres you:
With these new generation tyres, you can maintain the same tyre pressure in the field or on the road, whatever the load to be transported. For a given load, they enable you to use the same pressure. Their sidewalls were developed to widen the tread contact length, while the pressure can be reduced to between 0.8 to 1.2 bar.
To increase your yield, transport heavier loads and work more quickly, you need to increase the tractive force of your machinery by choosing farming tyres which best grip the soil. To achieve this, choose a tyre with a lug angle which is low in relation to the road. This provides you with a contact surface perpendicular to the driving direction thus optimising the tractive force.
When you buy your tyres, avoid discount models whose tread angles are too wide, as the more the treads are parallel to the driving direction, the higher the slip ratio, increasing your fuel consumption especially on loose or wet soil. The more you spin, the more you wear out your tyres.
You can look for new generation tyres equipped with treads with multiple angle or curved lugs. These models are the best compromise between the maximum tractive force and optimal self-cleaning. Some tyres are even equipped with lugs specifically designed to dig into the soil without a shovel effect, to optimise traction.
In conclusion, for farms specialising in field-crops and wishing to improve their productivity, the best tyres are undoubtedly those with VF technology, preferably larger and wider to protect your soil while increasing traction.
