Browse aftermarket replacement parts for the John Deere 6420 tractor.
Use filters or search by OEM part number. Compatibility details are listed on each product page.
The 6420 is a John Deere tractor in the 6000 numbering that shares hydraulic and transmission oil filters with the 6405 and 6605, along with the left hand door glass. The 5620, 5720 and 5820 use the same hydraulic filters, and the 6403 shares its mirror and gas spring. Match parts to the model and serial number on the serial plate, because filters, glass and electrical parts can change between serial ranges and engine options.
For the 6420, the left hand door glass replacing OEM L169102 and the full mirror kit replacing OEM M-245-5000 cover the cab, with the half mirror kit replacing OEM M-245-5000-L/R for one side. The hydraulic oil filters replacing OEM AH128449 and AL233526 and the transmission oil filter replacing OEM AT429938 handle service, and a switch is also available.
