Browse aftermarket replacement parts for the John Deere 5820 tractor.
Use filters or search by OEM part number. Compatibility details are listed on each product page.
The 5820 is the largest of John Deere's 5020 series utility tractors, introduced in 2003 alongside the 5620 and 5720. It shares its common filters with the 5720. Confirm the model and serial number on the serial plate before ordering, since filters can change between serial ranges and engine options.
Start with the primary air filter element replacing OEM AZ55542 and the transmission oil filter replacing OEM AT429938 on the 5820, then add the hydraulic oil filters replacing OEM AH128449 and AKK23814 when the hydraulic system is due. A gas spring, mirror, key sets and fuel filters are also available.
