   Good looking piece of equipment! A thought: What about changing the hitch to a u-channel setup for adjustable height & coupler options? I know that you can get pin, pintle, and ball hitches to fit the channels.

   Not a bad idea!

   Here is a better shot of the lift arm pivots

   Another thought: I see some chains that are bolted on to some of what appear to be pieces of angle iron. Even with grade 8 bolts, there is a chance of bolt shear and washer deformation due to the cantilevered stresses. If this is a lifting point, I would suggest a shackle/clevis or lift hook (straight-line pulls are best). My suggestion could be complete overkill, too

   There are threaded pieces of 1" bar welded to the angle where the chains bolt to the frame. So the last link is basically acting as a clevis. The forward chains that do the pulling are attached differently. So far-So good! I appreciate the input though! Hope it keeps coming!!

   Yair . . . cmartinweld .That's a well made implement but I don't see any adjustment for setting a crown? Several manufacturers make similar setups over here. They are probably not as heavy duty though and, on the stations they are often towed with a 4x4 pickup they use a 12volt linear actuator for lift. Cheers.

   Thank you! The rear 9' blade is adjustable to make the crown.

   Like it! Curious on cost. We have several miles of dirt road to our road and I rent a 140h twice a year. Would be great if it is cost effective!

   What flow rate / pressures are required for hydraulics?

    Nice set up....the only suggestion I might add, would be to use cutting edges.

11. #11ValleyFirewood2013-12-31 12:17

    Meant to be towed by a tractor and tie into its hydraulics?

12. #12cmartinweld2013-12-31 12:57

    Tractor or a small dump truck.

    Sent you a PM

    Do you have a design that would be towed by a truck? I think that would something people would use. Electric over hydro? I'm not sure how a dumptruck would tie into the hydraulics without patching into the dump system.

    I don't currently have a design for that but it would have to be much smaller. This design weighs three thousand pounds and typically takes a 100+ HP tractor to pull.

    Waiting for a deposit for another build. Will post pics once I get started. CM

    I'm only a year behind on this....
