Kubota Z421 mower

Foozle · Apr 15, 2019

I have a Kubota Z421 54" zero turn mower. I need to replace the blades, but am having a hard time finding the part. I looked in the user manual and there is no parts list. I went to the Kubota web site, and maybe I don't know where to look, but can't find a parts list there either. Amazon.com didn't turn anything up. Can someone point me to a direction on how to find the right replacement part?

Thanks!

Have you tried here, or any of the other Kubota dealers online?

Enter the exact model number for your mower & enter the deck model.

If yours has a deck: RCK54P-400Z

The regular blade should be: K5613-34350
The mulching blade should be: K5613-34340

$16.57 / each

Lots of people prefer gator blades over stock blades.

Sure no problem, they may be worth trying out at some point.

However I think the OP was just looking for the OEM part number to get started in finding any blades that will fit.

How do you like the mower? I just bought a Z421, 60" deck. So far great, but tires a little slick.
