  • AM39954

Before ordering, confirm your exact 50-inch mower deck model and serial number and the original AM39954 pulley reference. Tractor model alone does not confirm fitment.

Will this fit your machine?

For listed John Deere tractor models only when equipped with the compatible 50-inch mower deck using pulley reference AM39954. Confirm deck model and serial number, original pulley reference, belt grooves, hub, bore, keyway and pulley size. A tractor model alone does not confirm fitment. AM116141 is a separate speed-up pulley option; direct replacement of AM116141 by FLIP 708090 has not been verified.

About this replacement part

FLIP 708090 is an aftermarket center drive pulley assembly by Flip Manufacturing for listed John Deere 50-inch mower deck applications using pulley reference AM39954. The center pulley transfers belt drive through the mower deck drive system. This is an aftermarket replacement, not a genuine John Deere part.

What is included

Includes one pulley assembly, shown in the product photos. The photos show two pulley grooves and a keyed center bore. This listing is for the pulley component. Check your parts diagram for any key, nut, washer, belt or adjoining parts needed. Contact FLIP to confirm whether any mounting hardware you need is supplied.

Fitment and installation

Listed John Deere tractor applications are 140, 314, 316, 317, 318, 322, 330, 332, 420 and 430, when equipped with the compatible 50-inch mower deck using AM39954. Tractor model and deck width alone do not identify the required pulley. Confirm your exact mower deck model, serial number and original part reference in the equipment parts diagram.

AM39954 is listed as the standard-equipment center drive pulley. AM116141 is a separate speed-up pulley option, not a verified direct replacement reference for FLIP 708090. Compare the original pulley's grooves, hub, bore, keyway and size with this product before ordering.

Follow the service instructions for your exact mower deck. Confirm belt routing, pulley alignment and the condition of adjoining parts during replacement. Text your tractor model, deck model and serial number, original pulley number and photos to 903-320-4519 for help confirming fitment.

Aftermarket replacement part. Not affiliated with or endorsed by an original equipment manufacturer. Verify the listed part number, model, dimensions, and serial notes before ordering.
