homemade grapple ???

I really like your design! Some more close up pictures would be great. I'm probably going to begin one for myself this spring. Probably going to fabricate and attach to forks rather than my bucket though. Looks Great, you've got a good friend to help you out like that...good luck...Scozz

Thanks for the reply Scozz, I will try within the next couple of days to get some close up pics for you.....

My hydraulic cylinder is 2500 psi, 2in. bore, 8in. stroke, 1 1/8in. shaft, 20 1/4in. closed pin center distance, it also has adjustable threaded head at lower clevis which is great for fine tuning your open-close, I bought this cylinder locally, but is compares very close to the one at northern tools for $69.99 item# 9088408

Mlitt12345,

Very nice grapple. I think I too will be stealing your design. It is very similar to what I was thinking of doing from watching many of the great posts on this site. I was thinking of doing as PineRidge did and buy some of the precut pieces from, I think it was, Andy. I guess I keep being cheap and thinking I will build some. I would also like to see some more pictures when you get a chance. Thanks for sharing your nice work.

Russ, Andy Tatro is the name. If you send me a PM I'll be more than happy to furnish his contact information when you need it.

The size of the orifice can can be calculated by orifice sizing program and nowing the volume of the cylinder. But it would be beter to use a variable restrictor( needle valve) and adjust as needed. most hydraulics supplier have them. Along as its in the system between the directional valve and the cylinder it will work fine.

There are several ways to reduce hydraulic flow. One way is to use the smallest line. you can get, say 1/4. You could use a flow control valve inline. Picture below. The orfice thing is a trial and error, but will work, and is the cheapest. If you are using a standard valve, just feather the valve on and not go to max.

I have seen adjustable flow restrictors at Surplus City for less than 20 bucks. With just one in the circuit of a double action cylinder you can make adjustments until you get the speed just as you like it then lock the adjustment knob.

Since our snow plow uses single action angling cylinders it necessitated purchasing two, but they work great.
