Eastern Nebraska | We took our loader off of our Maxxum 125 Pro that we just got. We had some issues with the way the hoses were routed and with the help of the dealership we got the correct hoses and fittings and everything works fine.
Except when we went to hook the hoses back up on the quick couplers. There was pressure in the lift cylinders and we had to crack a line to release it I thought I had it in float when I unhooked the lines but I guess I didn't. Which hose should have the shutoff valve that you close when you unhook the loader. Should it be on the lift cylinders or the tilt cylinders? |

North Central Kansas | It is on the lift cylinder on my Quicke Q65 on the #2 hose. |

Eastern Nebraska | Thats what we have is a Quicke Q65 and its on the # 2 hose. I just wanted to make sure they put it on the right hose. I just must not have put it into float before I unhooked the hoses. So when do you shut the valve and what is the point? |

Somewhereville, Earth | youj got the flat face couplers or the pioneer couplers or the multifastner
the way the loader is removed there is always a small residual presure its needed to hold the loader up while parked
the shut off valve is in the lift circuit on the lower side of the cylinder circuit, its there for servicing and safety
i have seen farmers struggle like what you say connecting the pioneer style couplers, flatface will connect under a little pressure, better then the pioneer, and the faster multifaster is the best.
if you are using the fancy little tractor joystick some of them did have a float, some didn't i don't know what yours has

Eastern Nebraska | We have the pioneer couplers. We also have a joystick that has a float posistion. I thougth that the valve was there for the tilt so it would hold the bucket still while it was unhooked. Next time I'll just make sure that the tractor is shut off and I move the joystick back and forth plenty to relieve all the pressure and see what happens. Might just have to get the single point coupler. Thanks for the help!! |

North Central Kansas | I haven't had any problems with pressure when hooking up the loader. I have had problems hooking up the grapple. I finally decided that I need to shut the tractor off and run the joystick to relieve any pressure. Since I went to doing that I haven't had any problems. I just put mine back on the tractor this morning to fix a couple of creek crossings so we could cut the beans. First couple of times I took it on and off was a learning experience. Now it is so simple. |

Winkler, Manitoba Canada | Sometimes a change in temperature will create a lot of pressure in the hoses. If you remove the loader early in the morning when it is cool and try to reinstall it in the middle of the afternoon with the sun shining on the hoses and cylinders there can be a lot of pressure in the system even if you equalized the pressure before removing the loader. |

| We had the same problem with our loader. Finally got two male pioneer couplers with a pipe tee and a 1/4 turn valve. Plug the two hydraulic lines into the male couplers after you take the loader off and the pressure will usually equalize in the two lines. I put the 1/4 valve in the tee to give me another way to release some pressure if needed. Not sure whether I needed the valve but can be used if pressure has built up in the lines. Our problem was with the change in temperature not releasing pressure before disconnect. |
