VarioGrip, the right tire pressure for every application

VarioGrip™, our factory-installed tire inflation and deflation system allows the operator to set and control tire pressure, ensuring minimal compaction, less tire wear, and maximum performance in the field or on the road.

Up to 8 percent more area coverage in the same amount of time

The right inner tire pressure delivers more force to the ground and therefore more pulling power. Adjusted inner tire pressure effectively reduces slip and rolling resistance. And that has a positive effect on area coverage. If the high inner tire pressure is reduced during heavy-duty cultivating work, the tire’s ground contact automatically increases. This reduces slip and increases efficiency, which means up to eight percent more area is covered in the same amount of time.

At 500 hours of heavy-duty draft work per year, this means up to 40 hours less working time. Calculated per operating hour, this results in a higher area coverage and at the same time reduces diesel consumption for savings of up to $11.42 per hour. Assuming the tractor is used for heavy-duty draft work half of the time, this amounts to a $57,101 savings potential in 10,000 operating hours.**

Up to 3% faster

An inner tire pressure of 34 psi instead of the usual 26 psi on the road shortens driving time by up to three percent, while consuming two percent less diesel.

34 psi bar inner tire pressure on the road means:

3% shorter driving times
2% less diesel

Up to 8% more area coverage

During tillage, the optimal tire pressure of 11 psi, instead of the usual 26 psi, can increase draft performance by ten percent. This increases area coverage by eight percent while reducing diesel consumption by eight percent per hectare. For 500 hours of heavy-duty draft work per year, this means 40 hours less working time.

11 psi inner tire pressure means:

10% more pulling power +
• 8% more area +
• 8% less diesel +
• 40 hours saved per 500 hours of operation

Up to $11.42 per hour saved

Per operating hour, this results in savings of $11.42/hr for heavy-duty draft work. In 10,000 operating hours, of which 50 percent is for draft work (i.e. 5,000 operating hours), $57,000** can therefore be saved.

VarioGrip protects the soil and enables high yields

Less compaction

In farming, lower soil compaction is generally achieved by reducing the contact area pressure. Less air pressure in the tire means more contact area. The load is therefore distributed over a larger area.

More traction
The right inner tire pressure increases efficiency and enables gentle transfer of the tractor’s power to the ground. This results in improved soil fertility and higher yield.
Greater fertility
Air and water are stored in pores in the soil. A fertile soil is characterised by around 40 percent open pores and 60 percent solid substance.* The latter carries the entire weight during cultivation work. An adjusted air pressure contributes to the structure and maintenance of the pores.

Further advantages that are convincing.

Optimal protection

The protected design of the system ensures maximum operational reliability and longevity. There is no danger of ripping off protruding air lines.

Low tire wear

With the tire pressure regulation system, the pressure can be quickly adapted to the conditions. This effectively lowers tire wear.

Efficient compressor

The water-cooled double compressor ensures the tyres are filled within a short amount of time. The double compressor has a much higher output capacity than a standard compressor.

Tire pressure regulation system: The technology

VarioGrip is the fully integrated Fendt tire pressure regulation system that uses the vehicle’s own valve technology and routing of air flow. The complete solution is based on a water-cooled high-output compressor with two pistons, which ensures a very high-volume air current. Radial rotary unions are found on the front and rear axle. In this two-line technology, the control line opens the tire valve; the tire pressure is increased and decreased via the fill line. The rotary unions are subject to low wear, since they are only under pressure when increasing or releasing pressure.

A further advantage is that no air can escape from the tires when the lines are damaged, which means higher safety. The system is easy to control from the Varioterminal: The inner tire pressure for the front and rear axles can each be adjusted separately for field work and on-road driving. These settings are stored in the Varioterminal. In this way, the tire pressure regulation system also permits pressure control while driving.

Intelligent integration on the front axle

The lines for the VarioGrip tire pressure regulation system run through a radial rotary union. The valve on the tire is opened pneumatically via the control line (green). The air pressure in the tire can be lowered or increased quickly via the air line (blue).
