I'll show you slow!I've found that the tall stuff really bogs my flail down, I have the betstco fh-agl165 with hammers. I have to move extremely slow or the 5-6' "swamp grass" as it's called around here will drag it down and smoke the belts. I've never cut this field, we've had the property for about 2 years and I only got the tractor about a month ago. My plan is to hit it earlier in the year and try to keep up with it.
