1989 Ford 1210 clattering when hydrostat engaged....

[Jacey]

After using an auger in position, no problems there, I moved a few feet to discover a flat back tire...at least it felt like that, felt like it was off balance. Anyway, aired up the tire and noticed the tape had come off the hydraulic hose to the bucket, because it had blown while I wasn't looking...so this is just and endless seeming comedy of errors..until 45 dollars later, I had replaced the hose, bled it, and thinking all would be well, engaged the hydrostatic pedal to go forward and noticed a clattering sound, so i backed it and the same noise seemed to travel back beneath the undercarriage. Could this by related to the hydraulic, or totally unrelated? Or is there something I'm missing. Another unusual thing I'm thinking is the hydraulic fluid did not appear to have gone down any...even appeared a bit high on the dipstick. Oh well, hoping someone more brilliant than I has a less than worse case scenerio trouble shooting or answer to this dilemma. This is not the first time I've replaced a hydraulic hose, and never had the clattering aftermath before. Any help greatly appreciated!

if it moves alright just might be something just got loose and is resting on the frame. with it moving it vibrates causing the chattering. had a clutch replaced last summer. had a rattle at some rpms and not at others. seemed to be under left foot floor board. been trying to figure out the problem since then. looked and looked. finally found it by accident. after busting ice for cows a few days ago took my ax and knocked slush and snow off foot step. ax hit the steel step and there was that sound. pecked on it a time or two so i prized it away from the frame and stuffed a wad of paper towels in between. cured the problem. when it warms up find a piece of rubber and put it in there.

If only it would be that simple! I've come to realize although I've lubed all the sites with ports, had neglected to do anything to the axle. Apparently it takes hydraulic fluid, can that be right? Anyway, waiting for the schematic via e-mail from New Holland...but hasn't arrived yet. Mechanics can't do atttachments according to this guy. Anyway, I'll check that possibility. It does move, so not totally broken what ever it is. I lifted the hood and it's pretty much more centralized to that area now. At first seemed like the sound came from beneath and spread. High and Low gear same. Could I be in trouble of something in the drive shaft breaking, or broken?
