John Deere 450H Might Be a $100 Fix… or $15k Mistake

We picked up this John Deere 450H dozer with one heck of a story. It was sitting inside a barn until the barn literally blew away in a storm. Ever since, it’s had just enough power to creep in reverse… and nothing else. John Deere already tried the “easy fixes” — batteries, filters — but that didn’t do it. So we brought it back to the shop to see if this problem is a $100 filter issue or a $15,000 hydrostatic disaster. In this episode we: 1. Diagnose the hydrostatic transmission issue 2. Inspect and replace filters 3, Pull the controller to check for power and codes 4. Chase down stuck valves and bad pump behavior 5.Try to get this 450H back to pushing dirt again For early access to add free videos and members only videos be sure to check out our Patreon page.
