Hello I am looking for some thoughts from anybody having experiece with a diesel powered ZTR or similar equipment for sloped hill mowing, as well as large flat areas. I am looking at a Exmark FrontRunner, I am aware of the history on this unit, and a Steiner 230, both with 60" decks, because they are available and within budget. I can't fund anything new at this time. I now have 1 2/3 acre of dike wall to cut weekly and almost an acre, 5-6 times per season. The dike wall is 20-28 feet from side to side and 2500 lineal feet and 1300 feet. The slope is generally 30 degrees, plus or minus, with a crest 4-6 feet wide. See another thread I started with photos of the shorter dike. http://www.lawnsite.com/showthread.php?t=376371&highlight=dike I prefer diesel because I have several Kubotas now and diesel is less risk in Class 1 Div 2 areas where I mow. Thanks in advance for everyones input.
