Man, what a crappy day. I was in a backyard doing spring clean-up when the engine on my Dixon bogged down, and I wasn't mowing, just pulling a 42" dethatcher and I am pretty sure the engine is frozen up. It sucks! It's a 15 h.p. I had to push and pull it all the way to the front yard and load it on the trailer. AHHHHHHH, bad day. But I think it was her time to go. R.I.P. Briggs & Straton 15 h.p.
