I have not taken the deck off but I have traced the brake rod from the pedal to the transmission brake lever and can find no switch. The switch is represented in the wiring diagram but does not appear in any of the parts diagrams. According to the wiring diagram there is an orange/black wire running from the PTO switch to the brake switch, I have found that wire but it disappears into the wire harness under the floor...so I still can't locate it. Don't really want to remove the deck.Take the deck off, get the mower up in the air and have some one work the brake pedal
The switch in under the mower floor.

Lol. No problem. I'm going to figure it out one day.No problem with disagreement but nearly every mower I work on it is the case. With that in mind I haven't seen A TB 30 R. I only one toy ZTR mower ( 34" cut) on the yard currently. I have seen something similar at Walmart but a guy my size it disappear or look like a clown riding on those toy cars.
