1538 3 point without pressure

[txvrod]

So I have had this tractor for about a year, Mahindra 1538 Cab with FEL and Backhoe. Got all the connections for the 3 point and took off the backhoe, only problem is there is no power on the 3 point. The arms just go down as low as they can and wont raise. You can raise by hand and they just fall back down. I checked the connections of the backhoe with the 2 hoses together and these only fit one way so this is correct.
1. What are the chances the 2 hoses that should be connected do not have the right connectors? Backhoe works as expected.
2. Does anyone know on a 1538 where the 3 hoses are supposed to hook to the tractor? A diagram anywhere?
3. I tried the knob under the seat for the float but this did nothing. Tried several times after watching YouTube video saying this could be the problem. Could this still be the problem?

BUMP, NO ideas?

Might check the transmission sump screen filter, I had an old yanmar do that and it was the sump screen gunked up. Likely be messy.

Also check to see if there's a bypass valve. My Ford has a valve to share the three remotes I have with the 3ph. Mine is variable between all pressure to the 3ph to all pressure to the remotes. And any where in between. If a BH is being used, there's no need for 3ph pressure.

You may want to disconnect and reconnect the backhoe hoses a few times. I think I had an issue where one of them wasn’t fully seated after taking the backhoe off. I also think I had an issue with the flow control knob once and had to turn it back and forth a few times to get things working again. I also had my linkage bounce out of the saddle once. When this happened you could tell you had nothing connected to it though. If you still need pictures let me know my 1533 has the box blade on currently.

Thanks for the tips. I am going to try these, starting with the flow control knob again. I checked the linkage last time and it was connected but will trace it again just to be sure. Did the hose thing of connecting and redoing a few times without any luck, that is why I was wondering if the connectors could be on wrong. I'll look at it this weekend and update.

Tinhack: thanks, with these backhoes I think the bypass is in the 3 hoses. There are 3 hoses that go to the backhoe and once you remove it then you have to hook up 2 of the hoses together.

Unclewilli: thank you, I think that filters and oils are needed

I must really be missing something here. What does a 3ph have to do with a backhoe?

Are the lift arms attached to the 3-point hitch arms? I know it's a dumb question, but with a backhoe attached it's not unusual for some of the linkages to be removed.

Also, there's often a knob that shuts off flow to the 3 point hitch. I think on my Kubota it's in the center right below the seat. Do you see anything like that? If it's completely open or close in either direction, try backing it off.

My Kioti has a control that changes the 3pt hitch arm speed.
