Esoteric tractor advice #17: Support the third (upper) point on your bush hog with a short length of log chain rather than a fixed length arm (one can put screwable links of appropriate size on each end of the chain to attach to). This allows it to flex upward when you take it over a high spot, eliminating strain on the third point and bush hog.
