To 173abn, $529 with the B&S, $559 with the Kohler. The spec are identical except for the engines; Kohler mower is heavier, mentions the cast iron cylinder and forged crank and the Kohler is 7 lb-ft NET, not GROSS torque. Same wash out port, same self-propelled ground speed, same 5 year warrenty, same 5 coupons for a free blade sharpening ... Sometimes just posting something and going back and reading it makes the decision for me. Unless something really bad happens to Kohler in the next month, when I get my tax refund I'm getting the Toro Super Recycler with the Kohler engine and never looking back.
Thanks to all for putting up with me thinking out loud on this forum and thank you for your opinions.
