Cracks in Main Frame:

There have been some cracks in the main frame of some machete mowers

If a crack should develop (See Figure 1), use the following procedure to make repairs untill a permanent repair is developed. NOTE: This repair will aloow the machine to continue operating while a long term correction for the problem is being developed.

1.Grind out old weld (crack) and weld the crack, Do not use an exces- sive high repair weld as you will need to grind repair weld down smooth.

2.Prepare a piece of 1/2" X 6" HRFB cut to length (See Figure 2). The bottom should rest against the King Post frame and the top should be with in 2" of the top of the frame, this will determine the height of the repair plate (See Figure 3). Bevel the bottom side of the plate that is towards the frame to allow fortheoldweld.This willbeevedent if you test fit the repair plate.

3.Place the stiffener repair plate against the vertical memeber of frame (as shown in figure 3) and tack weld into position, Make sure repair plate is flat against the frame.
