Case in Point..... a 15 Year Old Toro Walk is Almost Identical to a 2005 Unit. Neither the Belts or the Hydros Have Changed Much in a Decade...The Toro Riders Finally recieved a Makeover w/a New Deck but Nothing Earth Shattering Why ? The Answer has Become Obvious... Price is the Single Most Important factor in a Mower Purchase....its not Cost Effective for a Company to Spend $$$$ in R&D and Engineering....At Least eXmark Upgrades Deck & Carrier Frame Design & Adds Minor New Features every Few Years.. Companies are Looking to Make Cheaper Mowers Not Better Mowers....Red Hawk....Bradley...Single Drive Hydros from Quick and Ferris and Simplicity etc...Price Driven...True Some innovation on the Quick 36" But Most of you Forget that Gary's Original Plan was to use Twin Kaws and Produce a True Commercial Unit.. Kudos to eXmark for Introducing a $1400- 26" Unit that the Scrubs Can't Afford..... and Not of Dumbing down their Tracer Line w/a Single Drive Hydro Unit. The Race is on to Make the Cheapest Commercial Mower Possible....Stay Tuned.
