Owner I own two Exmark walk behind mowers that are used to maintain 10 residential lawn a week. I do this as a part time basis to keep myself "fit". I want to let the Exmark people know that their products are simply the best. I have used other walk behind mowers and they were ok. Exmark products are made with thick gauge metal decking and heavy duty moving parts. These mowers are very easy to maintain on a weekly basis. Many people forget that engine oil and grease are very cheap in the "big picture". Keep making these superior products! Take care, Tom Sep. 27, 2014 -by Tom Z.
