Why not buy an old farm tractor? I have a 1950 farmall C with a 6 ft woods belly mower and a 1953 ford Jubilee with a 6 ft rear woods finish mower. The Jubilee has 3 pt. I trim with 4 ft huskiee varniee. The Jubilee works nice for leveling, push snow with a 7 ft blade, 6ft disk, 2 bottom plow, 7 ft cultipacker. Both tractors have pto.
Why are they better? Well they are 60+ years old, still work, still get parts for them. Will last my life time.
If you want a cub, find you a 1950 cub. They still work, no 3 pt. can get a belly mower.
Don't expect a lawn mower to do what a farm tractor can do.
You will be surprised how cheap some of the old tractors are. Get one that has been rebuilt and has good rubber. The price of rubber is more than a tractor is worth. George
