Okay, In the market for my 3rd ZTR. First two have been Scag 52" Tiger Cats with 27hp Kohler (SS Models). They are very zippy and I've been thoroughly pleased. Time for a new mower and all the local dealers only have on hand the model with the Kawasaki 691FX (22hp). It will cost around 750.00 more to order a 27hp Kohler model. Should I Go with the Kawasaki, or pay more for the 27hp Kohler? All advice welcome, Thanks.
