You adjusted the wrong thing. The adjustment on the rod determines WHEN the brakes activate, not how much brake you get. You need to adjust it back to the original point and then adjust the center nut in the middle of the brake on the side of the tranny. Tighten it a turn or two and see what you get. Don't go too far at once, just a little and test, little more, test, etc...

i adjusted the rod to original position, and adjusted brakes, but when i get the brakes where they will stop, the shifting stops again, i can loosen brake nut and it goes back to shifting

When you are shifting, are you hitting the clutch pedal or just shifting on the fly without touching the pedal?

You are activating the brake, even only slightly. That makes it hard or impossible to shift. Your mower's transmission is designed to shift while moving, but you aren't supposed to hit the pedal to do it.

Yes, you should be able to if the mower is at a standstill. I thought you were shifting while moving, right? If you are doing that, don't hit the clutch. If you want to stop and shift, do that with the clutch. Moving and clutching with the brake borderline too tight puts the works in a bind too much to allow the shift rails to pull the gears into alignment. If yours won't shift while stopped and the pedal down, that's a different story.

re

ok i see
what i meant was, it will shift on the fly now, but it will not stop, it keeps rolling slowly with pedal down, and when i adjust the brake where it will stop, it will not shift with pedal down, brake adjustment seems almost as tight as it will go to get it to stop, its almost like its not disengaging the drive system when i press the pedal at that point

thanks

Sounds like maybe you need to remove the brake from the side of the tranny and take it apart and free up the pins in it to make it apply/release freely. Might even need new pads (pucks).

thanks cheese, i have taken it apart, one pin seems to be more free than the other, how would i know when they are in proper working order? when they both move back and forth freely? Do they need to be removed from the caliper and cleaned maybe?
thanks again

Yep, pull them out and clean em up with a little sandpaper and lightly grease them before reassembly.

thanks cheese
i figured that was what to do, i took them out, got all the rust off with sandpaper lightly sprayed with lubricant, reassembled, brakes are a tiny bit better, stops pretty good at 6th gear, 5th a little worse, first and second just keeps rolling like theres no brakes(slow speeds) also shifting fairly good if rolling and i hit the clutch and shift, anything else i could do, the manual says there needs to be 1 and half inches between the brake lever at the caliper and the adjusting nut on the rod, could this help any?
thanks for all the advice

Tighten the nut in the middle of the brake a bit more. Just a turn or so and see how it does.
