Husqvarna RZ5424 Right wheel won't operate

[NCDiscgolfer]

Hey guys first time posting on this forum. I've done several searches and I've seen no resolution or fix for this problem. I'm hoping that y'all can help.

the left wheel operates in forward and reverse. The right wheel will not engage. I raised the rear of the mower, Removed the wheels and verified all pullies are spinning.

I followed the steps to purge air from the system After opening the link arm bypass and closing it after the purge.

The transaxle is EZT, RT
Part number is 510375602

This is a sealed unit which I will attempt to repair as a last resort.

I have not attempted to troubleshoot any electrical components yet.

Any help would be awesome!

Update: pulled the right transaxle out of the mower which was fairly easy. Removed what I believe is the fill plug that the vent tube is attached to. It was almost bone dry. Only a few drops of oil drained out. I'm going to fill with 20w50 tomorrow. I hope there are no leaks in the seals and I will update tomorrow if I can find time to fill it up.

They say these transaxles aren't serviceable but I was able to locate a service manual at hydro-gear dot com(can't post link). I hope this helps any one that may have a similar problem.

Mower factories sell the mower with "Sealed & Non servicable" trannies so they are not required to carry service parts for them.
It is all about inventory.
One of the BIG reasons why the imported Chinese stuff is so cheap is they have no parts back up nor warehouses nor delivery network.
These things cost a small fortune so by selling a "non-Servicable" tranny that puts the onus on carrying spares on Hydro Gear.
