Case 580c Return To Dig

Tinkerer · Oct 26, 2018

"That lever has 5 positions mine only works in 4. Up down left right."
The return to dig is not on the loader lever. You have to pull the RTD latch.
Does the float function of the loader work OK ?
That is how I interpret the manual.
Have you adjusted the linkage like the op manual explains ?
Most of the linkage parts are available.
Everything you need to know about the spools is in the service manual.
Actually I never use the RTD function on my own machine. It is completely unhooked.

I have often wondered if the RTD linkage / function was related to the common problem of the broken loader frame at the top main pivot. Mine has the self leveling function but no RTD linkage. My loader arms are original and unbroken and my bucket can be lowered when rolled back or not without any issues. Maybe there's no connection - I haven't done any real research into it beyond wondering why the guy I got it from ripped that linkage out. He was a pro and a smart old guy who didn't do things for no reason. I wished I had asked him when I could have.

Do you have the service 0r operators manual for your 580B Swampfoxo ?
The adjustments are in the operators manual.
An example.

My problem i dont think is an adjustment. Ghe main control lever will not stay in the rtd position on its on. It jumps to float position. Im thinking the spool valve is suppose to have a spot in it that locks the spool in the outward position till hit by the antiroll cradle.

The float position detent tension is adjustable, if that is the problem. Provided the spring that puts pressure on the retaining balls isn't broken.

RTD is a function that allows the cutting edge to be set at a preset angle for returning to grade and loading your bucket, the machine has both self leveling and rtd along with a float for the loader lift cylinders. The thing about rtd it's found on most const equipment that have a loader, when your bucket is off the ground say three feet or higher the bucket lever can be ingaged and released and it will bring it back to a preset cutting edge angle, the self leveling keeps material from spilling over the top edge, rolling the bucket out as it is raised and maintaining the selected angle you choose, the float allows the loader to go to the ground fast to ingage the ground and allow it to float with the contour as needed going forword or reverse. With the machine setting on level ground, check the tire pressure in the rear tires and adjust, place the bucket on the ground, pitch the bucket so the cutting edge is about 1/4 to 1/2 lower at the edge than the rear of the bucket and adjust the missing rod if replaced as needed for this setting, you may also have some elect issues at the loader valve and switches that need repair, ask all the questions you need !

I just purchased a 1980 Case 580c and noticed that the rod for the return to dig feature is missing, is this a big deal? and can someone please explain to me exactly what that feature does? also how do I search on this forum/site for a post/thread so I am not constantly asking the same questions as other members "I am totally new to this site" and don't wanna **** anyone off, this site is a wealth of info. any feedback is much appreciated. BTW if I type into the search box ex. "Return to dig" tons of posts come up but not pertaining to exactly that[/QUOTE

Great thats a big help does the other spool have a detent ball in ut aa well that hold the lever at the 45 degreee position. I have a manual i just olay hell understanding it. Im color defeicient. . My float feature lever straight forward works its just that it will not stay in the rtd position it jumps into float. I xzn put lever in 12 oclock position and it will float at the desired height but when i put it in 10 oclock position the spool valve u showed me engages the other doesnt so the levergoes to float everytime. Im assuming both spokls have a derent ball and i need to adjust the other. Am i making any sense. Thanksfor ur help. Any idea where i can buy partsfor these spools. Just for shots and giggles. Im looking at a 580c , i offered 500 dollarsfor it. If i get it im gonna fix it up and sell my b. Do u think theres a chance i can get 10 grand for it. Just yoyr thoughtson it. Thanks mike

10K for a B would be high around here unless it had been gone through and was in tip top shape. I would think any C worth fixing up would be worth more than $500. - It's scrap value is probably more than that. It's a heavier duty machine than a CK or a B that are really just glorified farm tractors. I'm not knocking them - just being honest - I love my old CK. Around here, a CK or a B that has been sitting in a field for 20 years goes for at least $1000 to $1500. and a C would go for at least twice that much and probably more.

Great soundz good. Ithink if j getig for 500 im gonna fix it up. It doesnt have thd shuttle liketheb does. I ghink ig woulx be easief to deal with besides i lovd doing it

Mike; The loader bucket will not float at a desired height. It will only float with the bucket on the ground. The float position is pretty much useless going forward (at least for me). Usually the front wheels will rise above the ground going forward when the loader is in the float position.
I totally agree with Grady's post about the value of the machines.

I've used float forward for pushing snow after the ground freezes - probably not something you'll use it for in Louisiana though.

Me too !
I didn't think that info would be relevant to Swampfox tho !

Swampfoxo · Oct 31, 2018

Only once but it would make a mess out of a dirt driveway

Swampfoxo · Oct 31, 2018

Ok ill use your info to see if i can get this thing to stay in the rtd position as im hands free with it.
