I am looking to replace my current Aussie made ride on which has not required anything other than oil changes for 18 years. But only US made equipment now available here and I can't decide between a Simplicity Regent 20/38 or Toro XL440 tractor type or Hustler 42' Mini FasTrak or Toro Z480 18/48. Toro does not seem to be as well built as the others. About 2 acres with one acre having grades of around to 8%. Simplicity dealer says he will not sell me a ZTR because pumps on domestic models will go in two years and very costly to repair. Hustler dealer says hills no problem. Who is right and if I go Hustler do I pay the extra $600 for the Honda or stay with the Kohler motor.
