BUSH HOGGING! I kept up 340 acres with a 4' bush hog for 12 years, you can imagine what all went wrong. The most challenging was when the pin on one of the lift arms got jerked out by the thick brush and came disconnected, I was going downhill in rutted out ground. One side of the bush hog was down on the ground and one side was on the lift arm, 450# of dead weight to lift a foot or, center the bush hog hook connection shaft with hole in the lift arm to hook back up and I was alone. Seems like I ended up piling up dead logs to make a ramp and dragging the bush hog up the ramp to raise the side that came lose.
I bought a set of Pat's lift arm quick clips after that, easy off and on.
