After extreme cold in Texas, my unit developed a hydraulic fluid leak on the rear left. It is in my garage and never experienced freezing but it did get cold. Any clues where this could be coming from. I have pics. The inside underneath is clean and it appears to start up top. Thanks for input.

Zoom in on last picture, it looks like seal at topside under fan is leaking & dirt is clinging to oil on transmission housing.

All of the oil around the seals looks minor, Where is the fresh oil trail coming from. Don't see oil in the pictures to account for the oil on the ground

I don't have an answer to that. It didn't occur until the extreme cold we had in Texas last week. I had wondered if a gasket or o-ring shrunk due to the cold.

Yes it is most likely a seal or o-ring that is leaking but everything is just a guess since model number has been posted. Just having the series name is not usable as we can't look-up the equipment except by the model number on the serial number tag.

Even thinking one of the sealing items leaking you would still to know which one. Most of the Hustlers I have worked use Hydro Gear transaxles or pumps and wheels motors.

I would recommend carry it to a shop that knows what they are doing since you are a novice at repairs.

The Model number shown on the paperwork is 932588, 54" cut.

Are you sure it is not 932566? It is the 932566 then the seal kit is 71410 superseded to 72994 for the Hydro Gear ZT-2800 series transaxle. Also it is showing an oil filter which might be loose.

But I have seen the oil pump cover oil ring to leak on a couple of these transaxles. If you remove the oil pump cover, pay attention to it orientation as it is directional; otherwords, if installed backwards the transaxle will operate backwards. Also these pump covers are noted to check for possible warpage. If is the pump cover leaking they can be changed without removal of the transaxle or at the last one I did change the oil ring for last Summer was.
