Wide-section and dual tires significantly
reduce soil compaction and
associated crop losses, increase the output of aggregates, reduce fuel consumption
by 30-40%, reduce slipping and tire wear by 2.5 times (Fig. 2).
According to the German company Grasdorf Wennekamp, when using wide-
profile
low-pressure tires on tractors, productivity increases by 40%,
costs are
reduced by 30%, and when dual wheels are used, productivity is increased by 80%,
costs are reduced by 45%. With an increase in the width and length of the tire patch,
the costs will not be large and the performance will increase dramatically.
Over the past 50 years, heavy agricultural machinery weighing more than 8
tons has been created in cooperation between independent states. The predominant
development of a conservative traction concept, when the tangential traction force
increases based on weight growth, has led to the creation of heavyweights of about
20 tons. Combinations of other designs began to be used:
rubber-reinforced
caterpillars, half-track variants, etc. However, their prices are too high, and therefore
the requests of agricultural producers for equipment with such a running system are
still met by no more than 10%. Nevertheless, research in this direction is actively
continuing (Fig. 3).
