I was having a hard time getting the bucket on my Bobcat 710 to raise and noticed that the bolts holding the left pedal in place were loose so the pedal was just shifting instead of moving the linkage. I straightened it out and tightened the bolts, but now none of the pedal functions work right. The bucket dropped so the edge is straight down and the arms raised by very very small amounts when I pushed the pedal but nothing else worked. I tried moving the pedal to different positions and retightening and even using a pry bar to gently move the entire linkage in and out a little but that hasn't been successful either other than one time when I hit a sweet spot that dropped the arms. I looked out today and because the bucket is pointing down and the arms seem to have crept to their fully down position, the front wheels are up in the air and the unit is sitting on its back end (making the door impossible to open). Because it does leak a little, a few years ago when I first got it I saw some large 'screws' that looked like they were at/near the source and tried to tighten them. That caused the functions to be completely wrong and the tilt pedal actually raised and lowered the arms. Of course I was really adjusting something on the control valve and not tightening 'loose screws' and it took quite a bit of fiddling with them to get it working correctly again (but it has been fine since then until the loose foot pedal). I can't find any reference on how to adjust the pedals. Can I just put them where they have the best travel and then adjust the screws again? The problem is that I never really figured out which screw adjusted arm vs bucket movement, what direction they needed to be turned. or how much/little they should be adjusted at a time (a tweak, quarter/half/full turn, etc).

See if your aux hydro is stuck on it can cause all kinds of funny things to happen
Not sure how to check that. I do have aux couplings on the front but I've never used them. I don't see any switch or other indicator anywhere for aux. Key, volt/hour meters, glowplug preheater switch, light switch, and a couple warning lights overhead. Simple sticks/pedals, brake, and power lever below. Nothing else in the cab.

First off are you sure about the model number because I've never heard of a 710. Now if its a 700 with aux. hydraulics it should have 3 pedals, the middle one controls the aux.
If you have a hose, put a loop from one aux coupler to the other and if that cures the problem you engaged the aux partly when you were adjusting the pedals. That is what the hydraulics do when the aux is partly engaged.
OldMachinist, you are right it's a 731 not a 710! I had just read a post about a 610 and I scrambled the number just like my hydraulics were scrambled. Jerry, good call on the hydraulic hose as well, that would be a good way to eliminate that as a problem (but unfortunately I don't have a hose). I couldn't leave my baby out by the street on the front yard so I went back to the pry bar this afternoon to see if I could at least get everything in a position that would allow me to drive it into the garage. With a bigger bar, I got the arms to go up and down a couple times and the bucket tilt started to work again as well so I tightened the bolts where they were, threw the seat back in, and we've been working since then. The problem is that I have to reach down and pull the top of the pedal towards me to raise the arms since there is no way to push down far enough with my heel. It has always been difficult to push it down but now I don't want to mess with the position since I can at least use it! I really need it to work for the next few weeks but maybe later this fall I can try to re-adjust the pedal, unless there is a trick I am missing for getting it to work. I think I aggravated the problem yesterday by trying to tighten the pedal in a position where I could push the back of it down without a getting a special joint installed in my ankle. It does confuse me though because I would have thought if I moved it backward or forward too far and had pressure on the bar even when the pedal wasn't being moved that the bucket would have just gone up or down when I started it, reacting as if my foot was on it instead of just making none of the hydraulics work.

If you put that loop hose on you will loose some power but at least you won't be stuck again

On a 731 moving right steering lever sideways controls the aux hydraulics. It's possible while you messing with the pedals you may have pushed the lever all the way to the right putting it in detent mode.
Thanks for the info, I didn't know that and never bothered to find out since the only "attachment" I use is when I put the teeth on the bucket! It does have shiny new aux couplings so I've always wanted to try something on them
. You are right about bumping the levers, that was very possible given that I was straddling the open space on a tilted machine. There aren't many good places to put your feet and it isn't exacly spacious, especially with the levers intruding into the space and acting as things to grab to keep my balance.
