Exmark expanded its line to include new EFI-propane versions of its popular Turf Tracer hydro-drive wide area walk-behind models. The new models use groundbreaking propane EFI Kohler V-twin powerplants to reduce fuel expenditures by up to 40 percent. The automotive-style closed-loop EFI system adjusts fuel/air mixture in real time to deliver improved running and performance compared to converted gasoline engines. Both models are equipped with Exmark’s patented Enhanced Control System (ECS), which offers increased operator comfort and control with improved ergonomics. The Turf Tracer X-Series is available with a choice of 52- or 60-inch UltraCut Series 4 cutting decks, while the Turf Tracer S-Series is available with a 48-inch UltraCut Series 3 cutting deck.
