Will this fit your machine?

Match the mower deck model: RCK54-23ZG or RCK54GR. GR2110 owners must confirm the installed deck is the matching RCK54GR configuration; the tractor model alone does not confirm fit. Compare the gearbox number, shafts, mounting points and pulley arrangement before ordering.

About this replacement part

Flip Manufacturing 702999 is an aftermarket gearbox assembly for compatible Kubota RCK54-23ZG and RCK54GR mower decks. It replaces K5617-33102 and K5617-33100 in the mower deck drive system.

Confirm the mower deck before ordering

Kubota RCK54-23ZG mower deck
Kubota RCK54GR 54-inch mid-mount mower deck, in the matching GR2110 application

GR2110 identifies the tractor; confirm the installed mower deck and gearbox number. The tractor model or the RCK54 prefix alone does not establish fit. K5617-33102 is the service replacement for K5617-33100; this assembly replaces both numbers. Match the replacement listed for your exact deck and serial number.

Compare the input and output shafts, shaft projection, mounting points and pulley width/offset with your original setup before installation. Confirm that the mating parts engage correctly. If the arrangement differs or you cannot identify the deck, use the fitment help on this page with your deck model, serial number and photos before ordering.

Gearbox assembly or rebuild kit?

This listing supplies one replacement gearbox assembly. Choose an assembly when inspection shows that replacing the unit is appropriate. Confirm which mounting hardware and surrounding drive parts your installation needs before ordering.

If the existing housing, gears and shafts are serviceable and the repair calls for bearings, seals and related small parts, compare our 704375 gearbox rebuild kit for K5617-33102. The kit page lists every included component so you can check the repair scope before choosing.

Installation and lubrication checks

Use the service manual for your exact mower deck for disassembly, alignment, fastener torque and lubrication. Check the gearbox oil condition and level before operating; do not assume a replacement gearbox is ready to run without checking. Confirm the required lubricant and fill level for your application.

Compare the replacement with the removed assembly before transferring drive parts. If shaft engagement, pulley alignment or mounting differs, stop and confirm the application before operating. After installation, inspect for leaks and verify correct operation using the service manual procedure.

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.

Hi William, thank you for your kind words about our service! We're glad to hear you'll consider us again and hope the next part fits perfectly. Feel free to reach out if you need any assistance.

The part I needed was an exact fit

The part I needed was an exact fit, but it turned out the wider pulley prevented the shaft from reaching the blades. Normally, this would be a $1200 loss for me. But FLIP has an unheard of return policy. So I was able to return it. They even paid the return shipping!

We are glad to hear that the part you needed was an exact fit, however, we apologize for any inconvenience caused by the wider pulley preventing the shaft from reaching the blades.
