I am going to add a couple of remotes to my L4200 using my PB circuit (previously backhoe only) to run my snowblower hydraulics, but have been having trouble identifying the existing parts to which I have to connect. My backhoe and snowblower have the same male quick-couple connectors on their hoses. All of the remote connectors that I have ever seen look the same too - a guy at the dealer called them 1/2" something. What I need is a link to drawings of the common connectors, so I can measure what I have and compare, I guess.

Also, I was looking at valves at that Surplus on-line place - it looks like I can get a suitable 2-spool DA valve set for ~$140. There are also lots of valves with no handles that all seem to be ~$40. Do the handles cost $100? I really wanted a joystick, which seems a perfect match for chute control, but they are a bit pricey. OTOH, dual sticks would be better for future universal use.

What do folks typically do for mounting brackets? I have to re-mount my existing PB connector bracket (will interfere with 3pt hitch when hoses are connected) and have to mount whatever new valves I end up getting.

Lot of question Jay...Have you searched at all?

Here are some quick answers:

Here is a thread chart I use Hydraulic Warehouse - Size Chart to identify fitting styles.

The $140 valve is all you need, making your own handle is a PITA, and yes-they can be expensive if you can find them. Joystick valves can be bought for $180-$220, so they are not that much for in the grand scheme of things.

I welded a plate to my ROPS crossmember, some use U-clamps to clamp a mount to the ROPS.

Yes, quite a bit, and still can't find anything that has measured drawings.

I think you posted that link for me before. Doesn't help in this case - am not matching threads. I don't have any threaded ends - all of my hoses are connected. I will have to get new hoses and threaded connectors eventually, so I'm sure I'll need that sort of information, but for now, I am trying to figure out what size female connector hooks up to my existing piece of equipment (w/ male QCs). I don't know what they are called, don't know what size they are, etc. I have existing quick-connect fittings, and have been trying to find out what size/style they are for over a month. I can't bring them in to a shop since they are connected to 1500 pounds of machine. I have measured them, so I can produce a rough mechanical drawing of the connector - which should make identification trivial, but I have yet to see a chart that shows measured drawings of the fittings. For example, using a link out of the chart that you posted, there are 3 kinds of quick-connects shown that look like mine: Ag Interchange, 7241 Series A, and 7241 series B. Which one do I need? Don't know - they all look alike to me.

The $140 valve is all you need, making your own handle is a PITA, and yes-they can be expensive if you can find them. Joystick valves can be bought for $180-$220, so they are not that much for in the grand scheme of things.

Yes - it's not so much the cost, but I don't really want a float feature, and I don't think I can get a joystick w/o float. I still might go with one though - I joystick seems the perfect control for a hydraulic snowblower chute.

What makes things really hard is that I have to mail-order my supplies, so I have to make sure I know what is going on 100%. It would be awesome to be able to go to a hydraulic supply house and browse around and ask questions and learn about the jargon and . There is one about 20 miles away, but I can't go there during their operating hours because I have a job. It has been very frustrating, especially since my last foray with local 'experts' yielded bad information and steered me wrong for a while (never take advice from someone who wants to sell you something). I did finally learn enough to understand the basic systems, so now I just have to figure out the fine details.

thanks - JayC

Those QD's are removable, so take one of them off and send it to a hyd supply company, or someone like Northern Tools, of Surplus hydraulic. If you look at the number on the QD that you have, it can be matched up. I have posted charts of different manufactures part numbers.

Just tell them what you want and ask them to give you an estimate for the parts.

Just because the valve has float, does not mean you have to use it;)
