Performer 95 sprayer tyres

Do you know which are the best agricultural tyres for your sprayer?

Sprayers, whether towed or self-propelled, drive repetitively and always in the same part of a field.
This is why it is particularly important to choose the right tyres to reduce the impact of your machine’s wheels on your crops in the driving zones, limit loss of yield and increase your productivity.

What are the requirements for sprayer tyres?

The choice is tricky as there are numerous points to consider for this type of agricultural tyre.

Tractors with sprayers or self-propelled sprayers drive both on road and field, which explains the sometimes-contradictory requirements. In addition, the time slots for applying phytosanitary products or fertiliser are often very restrictive depending on the weather (rain, wind, etc…) it is not always possible to wait for the perfect conditions which would limit the impact on crops as well as soil compaction.

The tyres need to protect the soil from compaction, whatever the weather conditions. Due to their flexibility and their capacity to spread the load, radial type tyres are often recommended for sprayers.

How to choose between WIDE OR NARROW WHEELS

You need to determine the most suitable size. Choosing between wide or narrow wheels depends primarily on the type of crops. For crops in rows for example (market gardening, viticulture…), the width of the wheels depends on the distance between the rows, determined during planting.

The type of soil, and its load-bearing capacity and tendency towards compaction will also have an important influence.

Wide wheels are often preferred at the start of the season when the soil is damp and the vegetation not yet much developed. A wider wheel spreads the load on the ground for more stability on slopes.

When the plants are more developed and if the soil is not too sensitive to compaction, we advise that you replace the larger wheels by narrower wheels which will cause less damage to crops. Changing the wheels is often fastidious but you can use a wheel manipulator. The drawback is that you lose out on driving comfort as narrower wheels have less air and lessen shock absorption.

Larger tyres can also be used for higher growing crops (sunflower or rape for example) to protect the plants in the rows, between the wheels.

The advantage is their capacity to carry higher loads for the same pressure. They are therefore particularly interesting when the weather is wet, and the work needs to be carried out without delay.

This type of tyre limits the creation of deep ruts which make driving difficult in the fields during subsequent work and encouraging the erosion of sloping fields.


Pressure adjustment is unavoidable

Just like trailers, sprayers carry a variable load and drive on both roads and fields (regular farm/field routes).

It is therefore essential to check the tyre pressure regularly. In this case, a central tyre inflation system is a good way to maintain the most suitable pressure at all times.

The tyre is the best guarantee of the sprayer’s STABILITY

Tyre stability is important to optimise the boom’s steadiness and precision in the application of phytosanitary products.

It can be altered by the movement of the liquid contained in the tanks if the tyres do not sufficiently absorb vibrations.

The size of your tyres, in relation to your sprayer, and their profile will be decisive.


Self-cleaning of tyres

Choose a self-cleaning agricultural tyre, in other words a tyre which doesn’t gather a lot of earth. For this, widely spaced lugs are better than tighter lugs. You will limit the deposits of earth on the road or in the farmyard, and it will be easier to clean.

And finally, be sure to rinse your tyres each time that you have been using chemical products. This will significantly increase their lifespan, as rubber is highly sensitive to chemical products which damage them and accelerate ageing.
