BH15 vs older Ford 5' brush hog

[gasman1075]

I brush hog a 17 acre field twice a year ( mainly tall grass ) with my 2032R and older 5' Ford brush hog. No issues so far. I acquired a barely used BH15 ( 636 lbs) for a fair price and I am trying to decide if I should sell the Ford mower and keep the Bush Hog or sell the Bush Hog. I have never owned a Bush Hog branded mower never mind one as new or pretty as this one. So is there that big of a difference ?

Thanks in advance,
