I just bought a 781H Brown Trench Master at a yard sale. It is steerable with the 8 hp Honda engine. I dont even know what it is or how to use it. It jus seemed like a good price so I bought it. My questions are: What is it? How do I use it. Is the price ok. I paid $45 dollars for it. It seems in good shape and the engine works. Is it a useful item or should I try to sell it? Thanks for any comments or help with this thing.
