I have bought 9 brand new Turf Tracers and Turf Tracer HPs over the years. The last one I bought (a 60" with 24hp Kaw) is not very responsive in the Hydros. It has good ground speed in forward and reverse, but is not very "snappy" if that makes sense. The triggers do not return fast enough for my liking. I have had this problem before but it is usually a break in deal. After about 200 hours they seem to be outstanding. This one is now 2 years old with 1300 hours on it. The triggers are as sluggish as ever. Anyone had this problem? Like I said, this is the first Turf Tracer I have had like this. Any adjustments that you guys know of? Stiff springs? I don't think it would be a pump or wheel motor issue. It has to be within the trigger mechanism itself I would think. I also have a brand new S series (hp) 52" and it is already very snappy. It is just weird.
