TERRA TRAC study
Soil protection and cost advantages scientifically confirmed
Scientific studies at Cranfield University prove that tracks are worthwhile for large combine harvesters. Because of the reduced ground compaction, fuel and working time can be saved in subsequent cultivation. Therefore, the higher procurement costs for the tracks can be recouped.
Shallower lanes - less ground compaction
In comparing the lanes of a LEXION 580 TERRA TRAC to a LEXION of the same type with tyres, the tracks left behind a clearly shallower lane. The compaction caused by a combine harvester with tracks was limited to the top 30 cm of the turf, whereas with a chassis having wheels especially deep and intense ground compaction could be measured.
Low compaction imposes less cultivation costs
The compaction caused by TERRA TRAC is very shallow and can be eliminated by tilling with a cultivator or plough. Deeper damage must be remedied via a fuel-draining, time-robbing deep-ploughing operation using special equipment, which generates additional costs.
Additional information about the cost advantages that TERRA TRAC provides is available for download at the bottom of this page.
Plants grow best only in uncompacted soil
With oilseed rape roots capable of reaching 1.0m depth by Christmas, and winter wheat roots going down nearly 1.5m, crops need an uncompacted soil in order to thrive and perform to their best ability. In a compacted soil, crop growth is stunted as access to carbon dioxide and oxygen is restricted, plus there is reduced access to moisture and nutrients.
