The interesting thing about mine is that the side-to-side swing of the machine is not provided by conventional hydraulic rams. The swing is provided by a single rotary hydraulic 'cylinder' at the base of the boom. I've never had take the cylinder apart so I have no real idea how it works. There are no markings on the hoe so I don't know the brand. It may be a particulary Australian attachment because another Australian TBN member contacted me a few years ago after seeing one of these photos. The hoe has its own pump, powered by the PTO.
I can't post pics, but look up an Allis-Chalmers 918 Backhoe,and I think you'll be impressed. It's great for heavy-duty jobs....not gret for finesse work though.Digs 19 ft. deep.Front loader bucket lifts 6500 lbs. don-ohio ^)
Sounds like its one horizonal piston and the cylinder is connected to the chain for the side to side.The woods 650 and 750 are similiar.I had that piston leak from the first new delevery and was replaced. and no proglems since, except that I tore off one casting end but that was from sharp snapping caused from me and a rock..So in 25 plus years its done well seemed to lack alot of side swing pushing power but I assume it it had more then other pronlems would occure.QUOTE=alchemysa;3162333]The interesting thing about mine is that the side-to-side swing of the machine is not provided by conventional hydraulic rams.
