Sometimes one can find a very used unit with working parts cheap. I did this for our Offset 84" Twin Spindle Bush Hog brand cutter. (Basically two small bush hogs mounted side by side.) I found one that had been resealed and that worked good but the 3PH was somewhat twisted but worked at the time. I think I gave like $1200 for it (New they are $4K) and when the 3PH broke a new one was going to be close to $400. I found the same cutter that had been abused but everything rotated OK and some one had started rebuilding it and had put a new BH brand 3PH on it already and I bought it for $400 and put the 3PH on the first one. I have all the other spare parts.
Bush Hog, Rhino, etc new replacement parts are over the top price wise often.
