i have the 15 horse power DR. pluses are that it is very powerful and cuts brush great. i have make about 2 miles of trails around my farm and trails around the ponds. but you can not go right to water edge because it is so heavy it bogs. and on a very steep slope it will turn over. once i flipped it over into the water. if mowing accross a steep slope you must press down on the uphill hanle or it will turn over. so it is great for some things and not so great for others. it is very durable and never fails to crank.
