Question about Husqvarna Lawn Tractor 48" Deck, 23 Hp, Model# Yth2348
Transmission pin is in correct position. Brake is not on. I have purged the transmission. It appears the drive belt is not activated. What could cause the drive pulley and belt not to spin?

Sometimes the belt can jump off one pulley and cause the problem,follow the belt around all the pulleys and see if it came off one.there may be a belt loosening lever on the lh side of the mower deck, if so unlock it and reroute the belt around the pulley. If you need to replace the belt the manual has a good description on how to do it and should take 30 min with only a couple of tools.

As for whining sound I believe this normal. The purging instruction using the bypass valve ingaged on low engine running. Next with the bypass disengaged followed by the fwd with fast breaking and or rev with fast breaking actions to get the wheels to turning and getting better responce takes time. This does take some time to do - in my case 15 minutes or more. My tractor had 65 hours on it before it showed signs of not pulling a slight hill. I had to remove the transaxle and put in 50 wt. motor oil and with the purging I was able to bring new life back to this tractor. The original 30wt. motor oil is fine for a brake in oil and I did drain it and took the bottom cover pan off and cleaned the metal particals on the magnets and cleaned the filter. These transaxle are sealed but have a vent plug at the top of the case. That little plug is hard to get off with out damaging it. My tractor whins in forward and reverse but has good hydrostatic power now. So I say the whin is good!

Recheck your installation. It sounds like you perhaps got the belt on the wrong side of one or more belt guides. If you need an owners manual, post your full model and serial number and I will see if I can locate one for you

those fluid drive transmissions fail on quite a few brands as they all use the same ones....replace the trans...they are expensive but still cheaper than a new mower.

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
