The new PT-100 forestry compact track loader from ASV features an all-new sealed and pressurized cab, large dual pressurization filters, a high-performance air conditioner and heater, and full forestry guarding. An auto-reversing fan uses a pneumatic pump to periodically change the pitch of the fan blades, reversing air flow, and requiring less downtime for cleaning away debris and extending the time between radiator cleanings. Also standard is a screened engine pre-cleaner and heavy-duty skid-plates, which are hinged to allow access for cleaning out debris and other routine machine maintenance.
