Adjust play in brake linkage rod

[JimP2014]

It just occured to me, since this LT2000 is about 15 years old or more, it should have the problem where things are loose, like the belt for example or some other issue involving the pulleys BUT the problem is things are to tight! I did take the advice of Forest and not much changed. So instead of the ground drive belt becoming to loose ( this really should happen after 15 yrs.) it is now tighter. This makes no sense. It is as if I need to take the drive belt and stretch it a bit or buy one that is slightly longer.

I stand corrected the pedal has to much play in it - I wish I could just fix this.

The reason the clutch has lots of slack/play is the drive belt is worn which results in the clutching idler have to move too far to take up the slack. The more the clutch idler moves to take up the BELT slack the more forward the clutch/brake pedal will be for travel engauge disengauge. You might also have worn pulleys idle AND the top drive pulley worn on the sides allowing the belt travel too deep in the pulley.
It's quite a job to replace the drive belt and also properly inspect the pulleys. for example remove the deck, remove the front drive stack pulley or slide it down, carefully route the new belt and re-install all. After replacing this type drive belt I leave the deck off and test the drive BEFORE re-installing the deck. The mower will also have to elevated in the front. Quite a learning experience the first time doing such.
It's quite common for them type drive systems to have jack rabbit starts even with a new belt, might even be worse with a new belt.

Stay safe if under the mower. I use a chain hoist for such to make the job more user friendly.
Would be worth while to get an estimate for such from a shop.

Forest thank you very much for the detailed explanation! I now understand how the parts all work together.

Forest you speak the truth. I just grabbed hold of that drive belt and lo and behold it pulls back the brake pedal. I stand corrected it pulls it Forward towards the front wheels.

The other thing I noticed is when you pull the brake pedal all the way back towards the rear of the riding mower the belt seems very tight I would think it is supposed to be loose?

I don't know the way this moves back and forth I can't see it being the belt or the linkage rod it's some other thing it has to be it's right somehow in the the metal rod from the brake pedal going back to wherever it goes to on the other side of the riding mower that's what it seems like to me like that needs to be fixed and nothing else?

As the clutch is depressed towards the front the drive belt slacks.
As the clutch comes back the motion drive belt tension increases. (because the spring loaded clutch idler pulley moves into the belt)

Agree that in your video something appears too loose or to much slop in the clutch/brake swivel rod, but I do not know what?????
The video is not good enough to determine just what is upset. (maybe bolts loose or bushings worn?????
I added that additional pulley in red to that type mower. It kept the long run in the belt from flopping and less likely to jump off the pulleys.

I hear you on you don't know what it is because that whole setup is like the freaking Bermuda triangle trying to get in there you got to take everything apart I'll see if I can take the mower deck off and then I got to get a lift for the front end of it see exactly what's going on there's just no other way to do it it seems but thanks for replying and you have no idea what's going on there and I don't either but there's some sort of slop.
