Timemaster #1 is still making that horrible transmission noise - dealer still claims it's nothing to worry about. Timemaster #2 went down last week. Took it to the dealer and turns out it was the two little plastic teeth on the starter. Dealer fixed it in 15 minutes for me. All in all I really like these machines - But I don't see why some people say they are underpowered. I took them through some thick stuff and they handled just fine. Front setting on "C" - rear setting on "B" (TRY IT!) I think the reason why some claim they are underpowered is because they are A) Cutting too short B) Trying to mulch excessive growth and / or C) All of the above. Both my 30's have plenty of power, but if there was one thing I HATED about these machines it's how much the decks clog up. If there is any kind of moisture these things clog constantly. Other than that - Really a solid mower. They bag while discharging extremely well and while doing so you can cut excessive growth with ease. These machines have increased my productivity, reduced fuel consumption, and eliminate the need to double-cut excessive growth - really hard not to love them. I find myself not using the 36" walk behind at all since I got my 30's. Also the use of a 21" mower has become limited as well. Good Job Toro!
