Yesterday I got to demo two Toro mowers. I already have a Toro Proline 44 T-Bar. 1)Toro Proline 36 Hydro 15hp Kawi Pros Very easy controls True reverse Cuts great Discharges very well Leaves stripes without kit Light (Easy to do wheelie when loading onto trailer) 5Gal Fuel tank Cons Have to let go of controls to place in neutel(guy said there wasnt a neutel lock on the handlebars but it looked like it had one) I dont own it yet 2)Toro Z500 60; 28hp Kol Pros Comfortable seat Very wide tires 12Gal Fuel tanks Large hand controls Cons Cut like crap Clumped Discharged 20 feet or more (had to clean stuff that I never had to before) Very under powered (?28hp?) Scalped easy (some of that is me being new) Yard was brown after I was done To heavy for my trailer with my T-Bar on it (Jeep cheekee) So this winter I plan on buying the walk behind. Was a great machine and I was very happy with it. As for the Z500 I will be looking at other manufactures equipment.
