Catarpillars

Catarpillars have a greater effect of draft, than wheel. The main lack of the majority of catarpillars — the impossibility of movement on the asphalted roads without destruction of a covering, an exception is made a tractor with rezinotrosovy caterpillars. Small speeds of the movement of catarpillars (5-17 km/h) are compensated by the reduced pressure upon soil because of the big area of contact with soil, with the same weight, as at a wheel tractor. Catarpillars are widely applied in agriculture, on slabonesushchy soils and in the industry because of the unpretentiousness.
