Was pushing a small amount of loose dirt. Stopped moving, now rattling noise underneath. All hydro to loader and hoe work smoothly, fluid is ok. Linkage at gear selector and f/r floor pedals feel fine. Please help, and say it's an an easy fix.

By chance the range selector (low/mid/high) slip out of place so that the gears aren't fully meshed?

Crawl under the tractor to see if you've picked up a branch or something.
