Laser cut from 1/8" steel and powder coated in John Deere Green or Textured Black finish including a 2 coat process with primer for long life and corrosion resistance. All zinc coated mounting hardware included. No drilling is required for this guard. Photos of the textured black guards will be posted once complete. The black is currently in process and preorder only. **NOTE** The factory guard (frame) shown in the photos is for reference only to demonstrate fit and not included.
To install you may need to remove the factory guard from the tractor's frame. Start by removing the nuts at the pivot location and slide the bolts out enough to hold the upper and lower pieces together but still allow the 511 guard to slide into place. Push the pivot bolts back in and loosely install the nuts. Next, line up the upper holes of the 511 guard with the holes in the factory guard and install the smaller provided bolts, washers and nuts on each side. The washers should go between the 511 guard and the nuts. Lastly, install the larger provided bolts in 2 of the holes of the lower horizontal cross bar. There may be a gap between the back of this cross bar and the 511 guard, but it will draw up into contact once the bolts are tightened.
Reinstall the factory guard if previously removed.
