I used my first 6'RFM on a
B7800. It was a light weight deck and the tractor handled it effortlessly but the deck kept tearing up. Traded it for a Landpride 6' RFM that's built like a tank. The
B7800 and the
L3240 handled it but the
L3240 would slow down near the crest of the hill. The
B7800 had no problems with keeping power but when I would reach the bottom of the hill the deck would sort of swing the tractor which was no problem because I knew it was going to do it. I now do most of my mowing with my
BX2660 so I don't need the RFM. Paid $1750 for it, will take $950 for it. Never really used it over 6 times on about 3 mowed acres.
