Mowers pulled backwards drop the clippings in a ridge because they hit the pan and fall. A flying club with a grass field might want to build a mower like this as a group project. Mowing should be done early before spectators arrive. Everyone that sees it is curious but few folks give this thing the respect and distance it deserves. Since we are always fairly close to the mower, I'm hoping we overpower any alien signals.
Most small components are the same.
We used a Peerless 100-050 differential. The steering servo mounts on the rocking axle. Actually, most riding mowers now use some clever geometry to turn sharply. Of course, any combination of features can be used for a custom design. Both models mow right up to the edge of the deck on both sides for trimming.
