I have a John Deere XUV590MS4.

I recently did a routine oil change and its been downhill every since. The XUV turns on and idles - seemingly fine - but will only crawl when the engine is revved. The oil does not seem to be leaking but it does appear that some kind of fluid/oil may be leaking into the belt. There is a red check engine icon that comes on about a minute after turning on the machine and idling.

Im really at a loss. Any ideas?
