What This Is
This is a red replacement fuel tank cap for John Deere utility tractors, a direct fit for the original AT20911 cap. It uses a tang-style twist lock, the bayonet-type design John Deere used on these tanks, and a rubber seal that keeps dirt, dust, and water out of the fuel. It is the straightforward fix for a cap that is cracked, warped, worn, or missing.
Fitment
The cap fits a wide range of John Deere 20, 30, and 40 series utility tractors, including 1020, 1120, 1130, 1140, 1630, 1830, 2020, 2030, 2040, 2120, 2130, 2240, 2440, 2640, 3030, 3120, 3130, and 3140. The AT20911 number is cataloged for many more John Deere machines beyond this list, including earlier and larger tractors and some industrial and harvesting equipment, so if your tractor is not shown here, check the AT20911 number against your parts book before ordering.
Specifications
The cap measures about 2-5/8 inches outside diameter and 2-1/2 inches inside diameter, and it seats over a tank opening of roughly 1-7/16 inches. The body is red with a metal center and a rubber sealing gasket. Fit is by the tang, or bayonet, style used on the original. On a few machines the tangs may need a slight adjustment to seat cleanly, which is common with this cap across so many model years.
A Note On Venting
Fuel caps on these tractors can be either vented or non-vented depending on how the tank breathes. This listing is for the sealing replacement cap. If your machine specifically requires a vented cap, confirm that requirement for your serial number before you order, so you match the design your fuel system needs.
Cross Reference
This cap replaces John Deere numbers AT20911, AF2914R, and AR28483, and it cross-references to Sparex S.72197. If your tractor's parts list shows any of those numbers, this is the correct cap.
What Is Included
You receive one red fuel tank cap with its rubber seal. This is a single cap per order, not a multi-pack.
Ordering Guidance
Compare your tank neck opening and the tang spacing to the dimensions above, and match the AT20911 number or one of the cross references to your tractor. When those line up, this cap drops right in as a clean, sealed replacement.
