Most of the big names are good, look for the Kawasaki V twin engine with 20+HP. Another thing to look at is the hydrostatic transmission, they are not all the same. Some are sealed and cannot be serviced. The uprated ones have oil filters and can be serviced. Saying all that last year I bought a Ferris. Very happy so far 26HRS. Pushing it on 8 acres cleared that has to be mowed. Even though Ferris is now owned by Briggs and Straton I got one with the Kawasaki engine. It was about $3200, but I got a deal as I bought a tractor as well.
