I hooked up my killifer blade to my 175 and when I pull the lever back to the raise position for the cylinder it's in detent when I move the lever to the detent position it raises and when I move the lever to the lower position it lowers which is right so what is my problem?

So, is this a 3 point hitch implement ?? If so, have you ever used the 3 point hitch before?? The lever positions are RAISE (clear back)....HOLD (next position forward)...SLOW LOWER (Traction Booster position)..fast LOWER (DROPS LIKE A BRICK) clear forward. If this is thru your remote outlets you must have hoses crossed and/or bad/mismatched couplers/hose ends.

3pt works fine this tractor has dual hydraulics and I'm using the outlets on the right side which is the center lever on the console the left side outlet has a hose leaking when you move the lever so I'm not using it

Mack I'm confused too and I'm the one using it!!! Haha as Dr Allis said lever clear back should raise the implement but it doesn't until you move the lever to the center position and the all the way forward lowers the implement as it should so as goofy as this sounds I still need some help

If when trying to raise the implement (and it doesn't raise) you hear the engine and hydraulics groaning a bit, you have hydraulic couplers or hose ends that aren't compatible or defective. Your second story is a bit different than the first story.

Make sure the two allen screws on back of that valve is tight. MACK

Is the other lever in the neutral position? Does the remote have a float position? If so you may be going thru the raise position into the float position.

That's exactly how it is Gary like it is the lever goes from the forward back, lower then raise and all the way back is float it's like the raise position and the float is reversed, I know this sounds crazy but everything is hooked up correct

Some levers have a hole above and below pivot. If so switch holes. MACK

Compare the "FEEL" of this center lever to the lever to the left of it. They should both feel the same. Do this with the engine shut off.

The two remote levers have the linkage above the centerline of the pivot shaft. The 3pt lever is below centerline.

The levers are in the correct position Dr but the center lever when all the way back is in the hold position when moved one notch forward it lifts cylinder one more notch forward its in the lower position and the screws on the rear are tight as Mack said to check, the inside lever feels right but it has a hose leaking so I'm not using it

If Mack or I were there it would take all of 60 seconds to tell you whether it's the valve or not. Are you sure your lever isn't running out of rearward stroke because of short linkage issues?? All 3 levers when in the "hold" position are pretty much in-line with each other. If it isn't linkage, it's like there's something wrong with the spool centering spring mechanism inside the rear cover.

How hard of a job would it be to repair the hose for the inner levers' valve?

I think it's a internal problem because the lever will not back any further like the others, Dr are these valve bodies hard to work on? I guess that what you call them

Does the lever move freely like the other hydraulic levers? IF not, the valve section can be the problem. Growing up for many years, the center lever was difficult to move and did not work like it did before - pushing slightly ahead would raise and pulling the lever was so difficult it would not do a thing. We had to use the float position to lower the loader. When I restored the tractor, I took the section to my local hydraulic shop but they said it could not be fixed. I bought a new section from them (but does not have the detents) and everything works fine now.

Yes it moves freely the problem is the raise or lift position is reversed with the hold position moving lever all the way forward lowers the imp move lever to center which should be hold raises the imp pulling lever all the way back which should raise imp is the hold now, there is no adjustment on the linkage as its a solid metal rod

I'm going to speculate that the valve has something seriously wrong with it. Exactly what, I have no idea. I'm also going to speculate whomever bought the tractor brand new, never used the center lever or had any need to. The lever closest to the seat was the handiest, so no need to use the center lever. When the tractor became one-year old, the Warranty had expired and there you go. No one has ever fixed it in the last 40 years. That's a shame, because those Husco brand valves were very good and pleasant to operate.

Dr I have a update I hooked a AC blade to the 3pt after church today and when you raise the 3pt with a load on it after the hitch raises all the way up and the lever should kick back to the center position it Immeadiatly goes straight forward to the down position so after what's happened with this tractor I need to go back to church, I have another valve body I bought from a 190, will these parts interchange? What should I be looking for when I take this apart?

It almost sounds like someone has installed the 3 pt spool in the remote valve section and vice versa. And this is totally a wild guess.
