Cub cadet 5234d hydrostatic pump

[Fred1]

My 5234d tractor has lost ALL hydraulics. The engine is running and the drive shaft is spinning. But no steering, no moving forward or reverse, and no front bucket or 3 point movement. However the pto will engage and spin. Any help would be appreciated?

Have you checked the hydraulic oil level? Has it ever been changed? Filter change? The pump may have eaten the big one.

You can see the oil in the site gauge. The filter change was done at the service time 14.2 hours ago. What would cause it to go out all at once? Can I get a rebuilt pump?
