loader float

[Mike1955]

Ted, I so glad I'm finally getting back to you! foolishly I allowed an experienced (???) tractor guy try to get the 445C out of the mud. (I'm 90, can't walk and went back to house) Found loader into the clay mud. engine turn over but struggled to start. loader no response. I jacked up loader and engine improved. The higher the better the engine. I put it in forward slight clunk revved it up and wheels didn't react. might be clutch. Is there an adjustment I can try? I live on the 1st floor, so jumping out of the window won't help!

My guess is the front loader valve. Get that fixed and then work on tractor movement. Wish I was close I would help you. I don’t jump out windows

Mike, thanks for responding. As I disassemble the loader control valve, what do I look for?

Fred, when you chained the backhoe to the loader and activated the backhoe, I assume the backhoe moved, was working.

Did you move the loader lift valve at the same time you were trying to pick the loader up with the backhoe so that the loader cylinders could transfer oil out of the top of the cylinders?

The backhoe works as expected. The loader is on float. I jacked up the bucket a couple inches at great effort and now the engine runs without strain.

So you said that the loader lever will not come out of float, right? Perhaps it is actually stuck in between float and powering the bucket down, which is putting a load on the hydraulic system, bleeding off some of the necessary pressure to fully apply the clutch. That's the only other thing I can think of. Some evidence points in that direction if it was cranking with difficulty as you mentioned also.

Probably something stuck and not moving, a spool. It is loading the pump making it difficult to start. Either the valve or the remote cables if it has that. Your getting close!

Thanks for the encouragement.

Hire a young kid to dig the bucket out on the sides and front... then try to operate the loader. It may just be sucked into the mud without enough lifting force available to set it free.

suggestion, disconnect the upper hoses on the curl rams and tie off into a bucket(to catch the oil as loader bucket rotates ) then use the backhoe to drag your self onto the grass. Then sort the trans issue, and the loader issue.

Question Redman. How would it help him to move it?

Mike1955, the loader bucket is "locked" in position by the hydraulic curl cylinders. Disconnecting the upper curl cylinder hoses will unlock the rams allowing them to retract and the loader bucket to rotate flat and then slide on the ground as to OP drags himself out with the backhoe.
The bucket is to catch the oil displaced by the retracting rams.

Everyone has made good suggestions. I will disconnect the curl and try to drag it, if it doesn't rain for at least a week. The road in is either hard clay or mud.

Fred that is what I think an incomplete suggestion. If you take that route, then at least put a plug in the line you remove. Otherwise it be an oily mess

Thanks Mike, but my brain is in a tangle of sorts. If I plug the hyd hose, I don't think the piston will move one way or the other. However, since the loader is in float mode, it should be free to move. Am I right?

 

[redman135]

Fred Saas, Mike 1955 is right. I forgot to say to plug the TRACTOR side of the curl line. Drain the cylinder side into the bucket.
Good Luck.

No sir I don’t think that is correct. Once you take the hoses off it don’t matter. I wish I lived closer I would assist you. I’m not sure I would take this route but I’m not standing there looking at it. I believe I would trouble shoot it and fix it. I’ll bet it’s going to be a simple fix. Sir good luck

Y'all seem to be adamant about something I don't quite follow you I have a simple loader system on my 445C industrial model here is the layout. I think I just lift the loader bucket, which is on float, then tow it all out. If it is necessary to disconnect some lines, I will plug everything exposed.

Fred,

That is just the loader hydraulic system. I'm working on what I think the system looks like with the backhoe. Do you have a book on the 764 backhoe that might show it? Or does someone here on the site have one?
I am thinking that a quick coupler came off or separated (maybe not all the way) and is not allowing flow to the loader.

The flow comes from the front mounted pump to the backhoe, then from there to the loader. There also is probably a relief valve after the backhoe to the loader that is popping off if the coupler is disconnected.

Hi Fred,
Where are you located? I’ll come give you a hand if in the northeast.

Dunno, that is one heck of an offer! This forum has the best people yet. that has always been the way of farmers ---- earth people. I live in Alabama across the bay from Pensacola Florida on the coast of the Gulf of Mexico.

Fred,
A little far for me to come from New Hampshire. Was stationed at P’cola, nice area. Best of luck getting it sorted out.
