Looking at a new Turf Tracer HP, 19hp kaw, 48 inch deck for $4999. I was told it is a 2006 model from my local dealer. NO sulky. I'm not familiar with the different model lines of Exmark but from what I can tell the main differences between the Turf Tracer HP and the regular Turf Tracer are: 1. A different deck than the regular TT 2. Mechanical blade engagement. 3. Smaller tires. 4. Smaller engine choices. Anything there to make me look for a different model???
