So I am moving to a diesel mower. More power, less fuel usage, better durability, etc. 60 to 61'' deck. Mix of residential and commercial properties. Some big (4 acres) and some small (< .25 acre) Does anyone here have experience with these two machines? I am looking for advice on the best cut, does the weight cause ruts, and which model will stripe better. Both are Yanmar engines. The Ferris is a bit smaller, I know. Which would you go for?
