Alliance 373 VibroFarm – A technologically innovative and market specific tyre solution for e.g olive, pistachio, grape harvesting
Yokohama Announces the Alliance 373 VibroFarm
Practical experience shows that the demands for tractor tyre concepts are high, e.g. in olive cultivation, for example, on the Iberian Peninsula. Vibratory and harvesting machines are usually mounted at the front. This results in considerable loads on the front axle – not least because of the uneven load distribution – which places increased demands on the tyres. In addition, tractors are often also increasingly used for road travel and a wide variety of arable work on farms.
For these applications, the new Alliance 373 VibroFarm offers an adapted tyre concept. A new, reinforced carcass construction with steel belt ensures high stability of tyre and machine during operations, even under extreme loads.
The Stratified Layer Technology (SLT) developed by Alliance ensures high traction and low slippage, especially in extreme operating situations, such as slopes with heavy wet soils. In addition, a very high self-cleaning of the tire is achieved.
New hybrid tread profiles with centre block
A sinusoidal centre rib enables high performance due to minimised rutting and multi-angular sidewalls provide good traction on soft surfaces. A greater number of blocks and a high rubber-to-void tread ratio enable low rolling resistance during transport operations on hard surfaces and is ultimately increasing the tread life.
Graded lugs with mud breakers provide the self-cleaning ability of the tyre in addition to high traction. The diverging groove design, in combination with the optimised draft angle minimises stone entrapment.
Low cost of ownership
Overall, this increases the service life of the profile. The steel belt construction ensures high resistance to cuts, chips or punctures. This also leads to a longer service life of the tyre under the harsh operating conditions in e.g. olive, pistachio and grape harvesting. Due to the unique design, the tyre retains its traction throughout its life – according to initial practical experience. This ensures a low total cost of ownership. Alliance has also backed the tyre with a 10-year warranty.
Special solutions for farmers with specific conditions
“The new Alliance 373 is a good example of how we offer technically and market-specifically innovative tyre solutions. This is our first tyre concept developed exclusively for the Iberian market and the special requirements of olive, pistachio, grape harvesting, front loader tractor, following extensive user surveys and field tests,” reports Ole Baek, Vice President – North & West at YOHT.
