Question about Husqvarna Lawn Tractor 48" Deck, 23 Hp, Model# Yth2348
Instructions say to purge transmission by setting brake, place in freewheel, start engine, run in slow mode, then release brake. when I attempt to release brake engine dies. I have mower deck off. is there a sensor switch somewhere, besides the seat? thanks
First check the seat switch,make sure it is plugged in tightly, these plugs have a safety tab built into them that will cut the engine off if you unhook it,sometimes the plug latch pulls out slightly and this will cut the engine, There are two other switches in the system one on the foot clutch and on on the mower clutch, if you follow the white wire from you ignition switch it will lead you to both of them,check those connections also.

Tips for a great answer:
IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATION BEFORE OPERATING THE TRACTOR.
Step 1- Place the rear of the mower safely onto jackstands on a level surface with engine off and parking brake set.
Step 2- Disengage transmission by placing freewheel control, located at the back of the frame, in the freewheeling position.
2a- Mowers with seperate pumps and wheel motors the freewheel is activated by turnign the bypass valves, one on each pump, two full turns.
The oil resevoir needs to be filled to the specifications listed in the owners manual before starting the purge procedure.
Step 3- Sitting in the operators seat(riders), start engine. After the engine is running, move throttle control to slow position. With motion control levers in neutral (N) position, slowly disengage clutch/brake pedal.
Step 4-Move motion control levers to full forward position and hold for five (5) seconds. Move levers to full reverse position and hold for five (5) seconds. Repeat this procedure three (3) times.
NOTE: During this procedure there may be some movement of the drive wheels, but they are not under load. The air is being removed from hydraulic drive system.
Step 5-Move motion control levers to neutral (N) position. Shutoff engine and set parking brake. Check and add oil as needed for units with an oil resevoir.
Step 6-Engage transmission by placing freewheel control into driving position, or by closing the bypass valves on the pumps.
Step 7-Sitting in the operators seat, start engine. After the engine is running, move throttle control to full speed. With motion control levers in neutral (N) position, slowly disengage clutch/brake pedal.
Step 8-Slowly move motion control levers forward, after the tractor moves approximately five (5) feet, slowly move motion control levers to reverse position.
After the mower moves approximately five (5) feet return the motion control levers to the neutral (N) position. Repeat this procedure with the motion control levers three (3) times.
Step 9-Your mower is now purged and now ready for normal operation.For further information or assistance, we recommend contacting your lo
