I have a Rhino 3224 tractor, and was mowing with it last weekend. Made a couple passes and everything worked just fine. But I lost all lift on my 3 point and loader, but power steering continued to work. I assume the hydraulic pump is good, since steering was not affected, or no? Fluid level is good, tried it again this weekend, and problem did not fix itself. No visible leaks of any kind. Didn't have the time or tools to mess with, so looking for suggestions on where to start troubleshooting.
