L3430 HST Tranny Issue

[gregt]

L3430HST will not move forward or reverse and all other Hydraulics work.
Never made any noise just stopped moving. When I press the forward and reverse pedal it does nothing. Is this typ the way the HST tranny goes out or is there something else I should check.

Does the pto turn when selected? If it does, the issue is likely in the under-floorboard pedal linkage. If the pto doesn't turn the foot clutch is next in line of causes. Post back and we can go from there.

Same issue in all ranges?

Does this have a clutch?

Have you inspected the linkages between the pedal and tranny?

Clutch is gone or stuck.

Most commonly clutch issue. Only way to know is split it and inspect. If clutch is OK, post back-I have another idea, but we won't go there until the clutch is eliminated as it's the most common failure point in a complaint such as this.

HST's rarely fail in entirety. 2 of them I've seen in 3 decades and one was owner neglect/abuse.
