1850 Hydraulic Questions

A couple of questions about hydraulics on a new to me 1850 gas row crop, but probably would apply to other 50-series as well.

1. Is there a way to adjust hydraulic levers/valves for proper neutral setting? I've been running the tractor some while doing a tune up and have been getting a large puddle of oil coming out of the right
remotes when things are supposed to be in neutral. Which to me indicates that the valve spool is shifted enough to be sending oil to the remote. Otherwise, shouldn't oil in the remote lines just be trapped
and not under pressure to cause a remote to leak?

2. And for a simpler question that I should know, for the two ports coming out on each side of the hydraulic unit that serve the rear remotes (tractor has two sets of remotes) which port is pressurized when
you move lever forward vs. moving lever back?

Thanks in advance for any help!
 
That's normal on the hundred and 50 series to be pressurized. Only way to stop the leak is to replace the coupler.

I'm not positive, but I think on my 1600 the sides are opposite as to which one is up and which one is down.

If yours is like mine there is pressure even when your not calling for it, it's pressure both ways, equal. I can't uncouple lines to the bucket for an implement in the rear without shutting the machine off.

Keep the oil up, it runs more than the remote. With a bucket this isn't something that can be left go, steering and shifting becomes harder especially when coupled with a pto operation.

Congratulation on the tractor, I've had smaller that couldn't do what I want, was always frustrating. Just hooked and used a woods ditch bank chopper up. Requires a large machine to handle it, worked great. 3 point has no problem lifting it and the tractor shows no sign it knows it's back there. The chopper can be used single or double acting, since the olive uses double I can adjust and leave the chopper where ever I want. A leak in the system would not allow that, you need to fix that leak.

I really like the open center double action, but for one thing, I can't change to position of anything once the machine is off. If I want to drop the bucket pulling the lever does nothing, but it also stays where I put it. That takes pressure, that pressure is what causes things to leak. On other systems with a bucket you can't raise the front off the ground to work on it without leaving the machine running, not so with this system, but again a leak would be a problem.
 
Interesting about the remotes being pressurized when running. Looks like a trip to F&F is in order for some new couplers. Thanks again.
 
I forget the Pioneer part number, but get the ones that let you couple under pressure. Makes life a lot easier.

Take a male tip,put a pipe plug in it and plug it in. I put a brand new pair of Pioneers on my 1600 and they leaked right out of the box. That's the only one I've ever had to do that with,but it works like a charm.
 
I'm not familiar with the 1850. Can I assume the hydraulic system is similar to the smaller 50 series? My 1550 has the words BASE and ROD cast into the flange below the ports. And you may be able to relieve the pressure by opening the bleed screws. The valve spools are spring-centered, no adjustment. It may be a broken or weak spring or just the spool sticking. Again, this is based on a 1550 that I've had completely apart.
