Went over to look at 450c loader the neighbor has. Unit push good in a straight line but if you try to steer well in a push unit will just stop. If you step on the clutch and release it will move and steer again. Don’t know much about those unit so was wondering where to start looking for problems. Got filters and suction screen on order for it. Also was wondering what kind of oil it used as well. Thanks Frere
It needs the steering clutch and brake adjustment. Do you have the tech manual TM1102? You can pick one up online for $60 US. https://www.epcatalogs.com/john-deere-450c-crawler-tm-1102-technical-manual-pdf/
Drive train uses JD20C spec oil. Hygard is the stuff John Deere sells.
