Note: Steep hills cause my Lawn Tractor to loose traction and want to tip over. My "Antiroll, Center of Gravity ReLocator" fixes this problem. It also gives much more traction for backing up those hills with the extra weight. More weight or longer (outrigger weight rails) would give even more stability and traction on hills. I have also designed an electric Screwjack version with ability to "auto connect" it to the steering for constant CG adjustment. Other mods include, Bumper, Suicide knob, Chute Control, Noise Canceling earphones, Backup Utility Light, Horn, Hubcaps, Rear View Mirrors and Seat Sides.
Since moving here 4 years ago from California, I have had the pleasure of mowing my lawn. My Sears Craftsman mower works great but needed mods that I wanted.
I never researched or saw anything like this, but it may be likely of which I am unaware.
For me, it is a case of Necessity is the Mother of invention.

Thanks for watching, and all the support.
