Fendt 900 and 1000 Vario tractors are now available with a self-cleaning air filter, and the cabs come standard with laminated safety glass and a windscreen heating system.
The German tractor maker reckons to be the first to offer an optional factory-fitted self-cleaning air filter, which combines continuous dust extraction with active filter cleaning in a 30-second cycle. Blown out on the move, during the cleaning cycle, the filter is blown out twice, each with a 10-second pre-run and post-run.
The dust filter has its own 12-bar compressed air tank. The compressed air flow is controlled by a solenoid or pulse valve. Just before blowing out, the speed of the fan is raised and continues running like that for a short while afterwards.
The driver is notified about the cleaning process via a pop-up window on the terminal, so they can choose to activate it manually or automatically. The filter has a service life of about two years. This system requires a specially developed filter cartridge.
The chip proof laminated safety glass further helps to reduce in-cab noise levels. Single-glazed windows are still available as an option.
