Mulcher came with no instuctions or manual. Sales rep was unable to answer questions on controls, so I had to figure it out on my own. None of the hydraulic fittings were what I requested and once again the sales rep was no help. Had to go to a local hydraulic shop and spend another $150 to get adapters. I was assured that the blades were Tugsten Steel and very durable. First time I used it, I broke 6 blades and all the other are trashed. These are not standard blades as a google image search returned nothing. The sales rep offered what looks like a Quadco steel blade, but the price is really high, so I decided to look for that type of blade elsewhere. I got out my bolt thread gauge to determine the threads and of course none of my gauges worked as it's some none standard bolt. Sales rep was no help and said I should go to a hardware store to figure out the threads. My guess is I wont be able to find Quadco blades that have these threads and I'll be forced to buy their expensive blad
