If your tractor does not function as described, repair the problem immediately.
When the engine is running, any attempt by the operator to leave the seat without first setting the parking brake should shut off the engine.
When the engine is running and the attachment clutch is engaged, any attempt by the operator to leave the seat should shut off the engine.
The attachment clutch should never operate unless the operator is in the seat.
Note: The fault must be handled by an authorized Husqvarna dealer.
