DR PTO weedeater on BX 2200

[nc redneck]

I have searched old threads on this trimmer and realize it is a homeowner type product. It is light and would not cause BX to be unstable on ditches. Reason for asking is I have one property with almost 1/2 mile of fence. I have been using round up spray for the last 8 or so years and am starting to get wash out under fences on hills and ditches due to repeated round up spray. I dont expect $ 3000 dollars of performance out of a $ 900 dollar product. All of my research seems to indicate it will not a perfect attachment it is by far better than standing in hot sun for 12 hours with Stihl handheld. BX puts out about 17 HP at PTO it seems like it might be good match for this type light duty product. Rear tire width also seems like a good match. I have never had a PTO attachment hooked to it because of size and HP.
I also have a Kioti 45 but it is heavy, tears up damp areas in ditches, tire width does not look like good fit for this attachment.
Any reviews and/or advice with small tractor would be useful.
