John Deere 300 or 400 series Hydrostatic Transmission Teardown and Inspection what Common Problems

In this video I go thru the hydrostatic transmission for my 430 Deere Garden Tractor. Since I have had it it has been plagued with erratic ground speed issues that have continued to get worse. In this video I tear down a newer style hydrostat that has an improved linkage control over my old one and make sure it is in useable condition. Follow along for the commentary on what to look for and how I do it. Thanks for watching!
