Can I buy both and build a complete seat?

Yes. The frame assembly takes the cushions, and the AM3462T set supplies the seat and backrest. Check that the cushion screw holes line up with your frame before ordering both.

Which one fits my John Deere 420?

Only the AM3462T cushion set lists the 420. The JDS379ASY frame is listed for M, MT, MC and MI only.

The steel frame assembly should outlast the vinyl set. Vinyl on wood wears at the screw holes and cracks with sun exposure, while the frame only fails under heavy load or rust.

Do I need new cushions if I buy the frame?

Only if your current cushions are torn or the wood backing is soft. The frame assembly does not include padding.

Is the frame worth the extra over just cushions?

If your frame and latch are intact, no. If the frame is cracked or the latch will not hold, the frame is the part that fixes the problem.

Are these genuine John Deere parts?

Both listings are described as aftermarket replacements that cross to John Deere part numbers. The frame is stated as USA made; the cushion set's origin is not stated.

JDS379ASY New Seat Frame Assembly Fits John Deere M MT MC & MI vs AM3462T Yellow Backrest & Seat Cushion Set Fits John Deere

These are not competing versions of the same part. Product A is the metal seat frame assembly (frame, back panel and latch) for John Deere M, MT, MC and MI tractors. Product B is the yellow vinyl cushion and backrest set that screws onto a seat pan, and it fits a wider range of models including the 40, 320, 330, 420, 430, 435 and 440. Buy A if your frame or latch is broken; buy B if your frame is sound but the padding is worn. No prices were provided for either part, so compare store prices on each listing before ordering.
