Reaching out to those who know the difference. In my extensive research for the ZTR that would best suit my needs, I have reached a stumbling block. I'm looking to those how know, for info. In my search I came to this conclusion. My preferences are listed in order 1) Ferris IS 700 (60" deck, ZT3400) w/Kawa FS $8699 2) Gravely Pro Turn 160 (60" deck, ZT3400) Kawa FX $8962 3) Hustler X-one (60" deck, Parker motors) Kawa FX $10,690 Now, I most admit I was really stuck on the Hustler until I come up on those Parker motors. I'm hearing that although these motors are great, they are high maintenance because of the hoses. Can anyone here substantiate the high maintenance statement.
