Why tracks ?

� High contact area and very low ground pressure� Lower transport width in relation to contact area� High level of soil protection goes along with higher yields� Low slip capabilities in up hill applications� Secure staying on track in side hill operations� Harvesting capability also in heavy duty conditions� Higher seasonal performance� Optimized comfort with full suspension� Smoothness for header application
