I still think your better off with the rotary cutter, especially for "pasture". If you keep the blades sharp and go slow, the difference in quality of cut is minimal. The Squealer will certainly be more durable and require less maintenance, and like someone else said, if the grass gets too high, its a non-issue.
Before my "new" tractor, I used a Yanmar 1500 and 4 foot bushhog to cut my "first" 5 acres. If I went slow enough, it came out looking like 5 acres (re-claimed pasture) of front lawn...Nice! /forums/images/graemlins/wink.gif
