Whoa Nelly

On a 149 where I've replaced the brake lining with the 3/16 material from McMaster-Carr and it's been driven enough to "break in" the pads and clear the rotors of rust, I'm still not getting the stopping power I'd like to see on hills. I have tightened the adjustments to the point where it's somewhat difficult to push the tractor but on a hillside, it doesn't stop completely. Is there anything else I can do to hold it on a hill?

I would guess that the neutral return that hooks to the brake pedal isn't adjusted properly so the trans is pushing the brakes, sounds like its time to download the manual and start adjusting linkages. I'm not really sure why you even need brakes on a hydro tractor since you can just stop it with the control lever.

On hills? These are fairly serious grades.

When the dash lever is pointing straight down at neutral does the tractor sit still or does it creep?

It sits still. I'm sure it's not the trans pulling it because it stops quite well on lesser grades.

If you park it on a hill running, just set the lever to a point in forward or revers where it holds it. Or park it sideways on the hill (which is what you should do anyway).

Are you out of adjustment on the brakes? If not, keep tightening them.

How about a picture of where you are having trouble stopping. Just wondering are you actually sliding down the hill with the brakes applied and wheels locked.

I'm not going to disagree that that may be the case, but if so, then it's likely he has no control at all, and would skid down the hill no matter if the brakes were applied or not. (If that is the case, then he has a whole 'nother issue.) It's more likely that one brake is tighter than the other, or the hydro linkage isn't adjusted correctly as Tim mentioned earlier.

Reason I throw it out there is when I resurrect or want to test a machine, I've got a couple areas around here I can go up or down hill that you REALLY shouldn't on a routine basis. I have seen mowers slip going down hill if you go too slow or try to come to a complete stop. Just tossing out a fresh idea. Yeah I'm thinking something is probably out of adjustment as well. I don't know how the brakes on this one are set up but I seem to remember a 782 that if the rods were tightened up too far the brake rod would jam or something like that. Seems I had to cut a little off each rod, mind you I was dealing with old worn parts and it was a couple years back.
