Hyd question, tap into loader line

[robert23239]

Hi everyone,

I have an older deere and the loader is using the rear hyd hook up.
I would like to mow hay without taking off the loader. The mower has a single cylinder to raise and lower the head.
Can I tap into the loader to use that hook up ?

How can I keep the loader and user another hook up ???

Puzzled ?

You will have to add a new valve.
You can get a new joystick valve for $200 to operate your loader, then use the valves you have now for rear implements.

Tell me what machine you have and I can be a little more specific.

I have an older 3020 and I believe its a deere loader but not sure.
The loader hyd plug into the rear and I have nice two little controls on it for bucket tip and loader up/down.

Some one the other was also telling me that if you don't put a front loader down when tractor is parked it may get stuck. Is that possible?

The loader cylinders have been rebuilt so I was thinking of just unplugging the loader and plug in the mower. I believe it will stay up.

If you need something fast and simple you could get a piece of steel with a 90 degree angle and hose clamp it to the lift cylinder.

If you disconnect your loader quick connects while the loader is in the air, your lift cylinders will be under the pressure of the weight of the loader and may be very difficult to reconnect. You could also have pressure in the curl circuit from the weight of the bucket. You'll have a dangerous and messy situation if you loosen the connectors to bleed off pressure. At that time, the loader would drop and fluid would spray everywhere. I don't recommend disconnection with the loader anywhere but on the ground. Sorry, I know that's not what you wanted to hear.

Forgive my ignorance on this subject. Could one not just T off before the loader valve line and install a valve for the mower so then one line would control both functions, albeit one at a time? then if you need to re-adjust the loader you could in between adjusting the mower cylinder?

No, you can't just "T" off the pressurized line to add another valve.
Why can't you "T' off?
Because fluid will flow to the least amount of resistance. So when you try to operate one valve, the fluid would just flow through the "T" to the other valve that has no resistance on it. Vice versa when you try to operate the other valve. The new valve must be put into the system either up stream or down stream from the original valve. One valve would then feed the next one in line, preferably through a "power beyond" port. Each valve should have a return to sump or tank. Those return lines can be "T"d together.

My dad uses his loader hydraulics to run a log splitter. He leaves the hydraulics connected that raises and lowers the loader, but disconnecst the hydrauilcs that dump the bucket and uses them to run the log splitter. The only thing he had to buy was a set of hoses to run back to the splitter. It seems like the same thing could be done here.

It looks to me like the JD 3020 uses a closed hydraulic system (23gpm at 2250 psi). So I would have to say, yes you could tee into the pressure line going to the loader control. You would want to use a closed center valve. If the valve you use has a relief valve in it. You would want to set it about 300 psi higher than the tractors system pressure. Now, If someone had messed with the tractors pressure setting, it might be higher than the 2250 psi that the book calls for. To double check this. I would go to YTmag and ask the guys on the JD board.

Could you not put a flow diverter valve into one of the lines so you could lift the loader and then lock it in position with the flow diverter? then just run a line from the diverter valve to the valve for your implements and from the implement valve back to the tank?
