190XT Hydraulic Help Please

 

On the 190xt, if it is setup like all others I've seen, you should have 4 positions that each lever for the remotes (hydraulic lines on the rear) will stay in.  The rear most position will raise the implement (when the correct hose is connected to the correct port), the 2nd from rear position will hold the implement in what ever position it is in, the 3rd from rear position will push the implement down on a double actiing cylinder (has 1 hose to each end of the cylinder), and the farthest position ahead is called the float position and it will allow the cylinder (wether it has 1 or 2 hoses) to go up or down however it feels.  So on your drill if you connect the 1 hose to the correct port on the rear of the tractor, when you pull the lever all the way back, it will raise the drill until you stop it, or it reaches the end of the cylinder travel which at that time it will kick the lever from the raise position to the hold position (2nd from the rear, also it will do that in the lower postion going back to the hold too).  Then when you want to lower the drill, just push the lever all the way ahead to the float position and leave the lever there until you want to raise the drill this will allow the drill to go deaper into the ground if it wants to, or you can put the lever in the hold position if it is going to deep, and it will keep the drill at that level.  On a side note incase you do have a different hydraulic system, like on my D21, and a lot of other tractors (makes and models) there are only 3 positions that the hydraulic levers have, and that is up, hold, and down.  On these systems, you can make your single acting cylinder work by just holding the lever ahead to lower the implement then putting the lever back in the hold postion, but by doing that it will force the oil that would normaly go to the other end of the cylinder to go past the relief valve because there is nowhere else to go, and can cause your hydraulics to overheat if the system can't get rid of the excess heat generated by opening the relief all the time when you lower the drill, generally though it isn't a problem unless you are doing a lot of short rows, but if doing that, you just need to use some common sense on monitoring your hydraulic temp.

I think all 190 tractors have a float position on the remote. My 190 works fine on a haybine with 1 hose, power up and gravity down. I would check the hydraulic coupler, it may be letting pressure through to raise, but will not let the oil through to go back down.

Perhaps the 190xt's with front end loaders have different hydraulic systems?  The FEL hydraulics need to push up and push down - its not push up, gravity down like you would find on a three point linkage.

The guy who I bought this drill off had it working on his tractor a few weeks ago.  So I know its something to do with my tractor's hydraulic system.

Step 1: Raise hydraulics
Step 2: Disengage transport linkage on drill
Step 3: Go enjoy your new drill

Hydraulic couplers on the tractor don't like the hyd hose ends.

Yes I agree with doc too, had this problem on a case last year and it was the couplers.The springs inside need too have the same tension on each poppet or one or the other will close and stop oil returning.

i use the float position on all my tractors alot, even with 2 way cyl's, and i agree with doc, if your hose conectors fit together, doesn't mean they will work properly. unhook your hyd hose, match it with other hose ends from your other equipment, also look for wear on your hose end. i have found that AC and IH (older machines) interchange, or use pioneer fittings both male and female matched set. some of my equip is 2-way and some 1-way, both work well on all my tractors.

Its fixed, guys.  You can rest easy!  I'm out seeding now.  It was the hydraulic couplers.
