After reading about the dangers of sticks and snags when using a grapple, I decided to make a brush guard for the tractor.
The 4300 already had a frame of sorts that surrounds the radiator grill so I just needed to fill in the gaps to add more complete protection. I already had some expanded metal on hand. It was of the type that has a smooth surface.
The frame that comes with the tractor has a crossmember across the middle, and one that runs from it to the top part of the frame. One one side the cross members are recessed about 1/4". I place the expanded metal in this recessed area so it is flush with the front surface of the frame. Torched out the rough shape, and a little grinding and some careful welds. Then a rattle can of Ace John Deere green.
