My girlfriend bought a rototiller brand tiller at a swap meet. Its a model 3. Got it running and tilled with it. I noticed that the tines never stop if the machine is engaged. So if its going forward the tines are always on. I thought that was odd. And something else I noticed it doesn't have reverse. Picture not hers but just like it. It also came with a front mounted sickle mower. Thought that was unusual.
