I'm looking at a 52" electric-start eXmark Turf Tracer HP. I've got a good dealer (in terms of service) very close by, and am willing to pay some premium for that--but don't want to get shaved too close. The price I'm being quoted is $5149 plus a 2% surcharge to qualify for the "free" financing . . . reactions? Also, is there any disadvantage to the 52" deck over the 48" deck on hills? Next, I'm a little confused re. striping with the eXmark WBs--does eXmark not sell anything made for that purpose? Finally, I've seen references to the Proslide being used with belt-drives; any reason not to use it with hydros--and does anyone who's used a Proslide have a bad opinion of it? Thanks!!
