Small Engines (Lawn Mowers, etc.): A Lawn-Mower Engine to be sold., briggs and stratton, lawn mower engine

Question
Yeah, I was just given my dad's older lawn-mower on account of him buying a new one. The actual brand of the mower is Yard Machine that isn't old at all and looks fairly new with the engine being in the best shape. It has a Briggs and Stratton 20hp. I/C Twin 2 engine which runs great !!! My question to you is how much aroundabout could I sell the motor for and an estimate w/ the body and blades put back on. I would REALLY REALLY appreciate a response from you and hope to hear from you soon ! Thanx, Max

Answer
I am not sure I understand the question.  You want to know how much you could sell the engine for?

And what about the body and blades?  Are the blades off?  Bent?

How much you could sell the whole Tractor for?

Please rephrase the question.

Do you have 2 engines?
