2 single acting cylinders 1 remote

[CCWKen]

Let me explain my thinking a little. On my tractor you pull the handle up to activate one port and down to activate the other.
No sir. You are activating both work ports when you move the handle in either direction. As Kenny explains, one port is pressure the other port is return. Moving the handle the other way just reverses which port is pressure.

This may be what is meant by 2 remotes?
No sir. One valve, one remote. A "remote" has a pair of ports. When one port is supplying pressure, the other port is returning fluid to the tank.

I was under the impression that 2 remotes would have 4 ports.
They do. But you can't operate remote-1 (port pairs) with the remote-2 valve.

I don't understand why with this setup I would have to have the small table home before activating the large table? If the cylinders return due to gravity or Springs or whatever then I should be able to activate the large table while the small is coming down.
Cylinders don't return on their own. You have to activate the valve to allow fluid to exit the cylinder through the output port of the valve and back to the tank.

If you want the tables to act independently, you need more than one valve.

Check out this homemade hay bail stacker. I think this is ingenious. It even alternates each layer.

If you want to keep it simple, use one table that tosses a single bail when it comes out of the shoot. This is a little hard on the bails though.

I sure don't mean to beat a dead horse but I'm still confused by what you guys are saying vs what I saw. When I run my moco (JD 1219 with a single acting cylinder to raise and lower) with my tractor I only use one port. I have to put a chain (weight) across the remote handle to hold it down and bump the revs up to make the mower raise to pull the transport pin. When I get back on the tractor I take the chain off, the handle returns home, and the mower goes down. This is why I had the idea to run 2 single acting cylinders with one remote. Or do I have a problem in my valve that allows the fluid to return without the handle going to the other position?

For the guys that know more then me about motor spool valves. Do you think he could use a motor spool valve, like a 4 way 3 position with work ports open in center?

I think you may, if the handle is in neutral (it is 3 position (ON-NEUTRAL-ON) correct?) then the fluid should not be allowed to leave the cylinder-it should hold whatever position it is in. If your mower is lowering in neutral, then you either have a motor spool valve where both ports are open to the tank, or your valve is defective.

I can assure you that hanging a chain on the handle is not SOP (standard operating procedure) for remote operation unless your trying to get constant flow to something like a logsplitter or backhoe.

If he is going to the effort to add a valve, he should just add a second one that will control the second cylinder-and use the first original valve to control the other (if it's not bad however given what he last described)

Ok. A possible problem explains why I had to use the chain. Would you folks mind elaborating a little on the other ways besides hydraulics to achieve what I'm after?

Is there something I could look for on my valve to verify if it is a motor spool valve? From your comment I assume that if it's not a motor spill valve then I do have a problem.

Thanks to everybody so far for the help. I forgot to say that before

Can you post a picture of what you have? Including any numbers on the casting. Is the tractor really an AC CA?

It may be easier in the long run just to add a new two-spool valve replacing the single one you have now-then you know exactly what you have.

Here is one should work for you: 2 SPOOL 8 GPM PRINCE MB21BB5C1 DA VALVE

It's funny you mention a CA as I have one but, no, this tractor is a 1980 Long 610. I'll get a picture one day this week. Getting 70,000 baby chickens tomorrow so I'll be a little busy for a few days. LOL
