Troy Bilt Bronco Riding Mower Transmission Problems. Today, the transmission isn't working correctly.it was put in reverse, blade was disengaged. Install the new drive belt.
However, that is more of a problem with variable. This has me contemplating taking action to add unirex n3 grease to my sealed transmission to prevent the same fate. The drive pulley on top of the transmission will not move by hand in forward, neutral or reverse.
