3200 Braking/Differential Problem

[epare]

Hi,

Today, with the mower deck removed, to get more travel of my forward pedal (and, consequently, less travel of my reverse pedal), I extended the combined length of the forward and rear control rods, by making that adjustment on the underside of the machine. At any given rpm, the tractor now moves forward much faster than it did previously; and, reverse speed is still acceptable. Prior to this, the reverse pedal height was twice that of the forward pedal.

The problem, however, is that the brake now does not work; and, when I depress the brake pedal, I hear what sounds like a binding in the transmission. It seems that, when the brake pedal is pushed with a lot of force, there may be some movement of the differential lock pedal mechanism on the left side of the machine. I'm not sure that this is causing the noise within the transmission.

I should note that I do not understand the mechanism by which the disc brake pads are applied to the brake disc. I do see a lot of sloppiness in the brake actuator arm; but, I don't see how that would be affected by the one adjustment that I made.

Any ideas?

Thanks.

Is it a trans mounted, external disk brake on the 3K's? If so, it's the same setup as on my 2544. (if so) These are only intended as a parking brake and are not designed to repeatedly stop a loaded machine. From what you describe, it sounds like the F/R pedals is not returning fully to the neutral position prior to you pressing the brake pedal. Just a guess. I'd check the linkages and the linkage motion dapener cylinder (the little gas strut).
