I need some advice; I am looking to upgrade my cutting units. The Exmark Turf Tracers with ECS have caught my eye. My specific questions are directed to experienced users only. Of the two types HP and the reguler Tracer what are the strengths and weaknesses of each. Also, with the ECS system how do you handle raising the front up while on a sulky? is this even a issue with the floating deck? Is the ECS system really all that Exmark says that it is as far as comfort goes. Also, what should one expect to pay,at a good deal rate, for each unit. I am looking at the 52" model of each type. Thanks for all advice given.
