Folks, I have a Deutz-Allis 916 Hydro, which I believe to be the same as the Simplicity 7116 Hydro. My engine is currently out, and I'd like to push the tractor a couple hundred feet out to my back shed. Is there a way to disengage the transmission so that I'm not fighting against the transmission? It's a bugger to move. I can't seem to find anything about it in the user manuals. Thanks in advance!
