I'm fairly new to both Kubota and zero-turn mowers. I appreciate in advance any help that can be provided. I did a search for this topic through this site but couldn't find anything. I want to remove the deck of my Z421 60" so that I can do a better cleaning job AND replace the blades. The instructions (I use the term loosely) in the owner's manual are incomplete and the Kubota maintenance aid (a video available through the Kubota app) leaves out too many steps. I showed the video to a Kubota mechanic at my local dealer and he said, "I don't do it this way. Go on YouTube and find a video." Well, I went on YouTube and I can't find a video that is relevant.

My ask is this: Does anyone know of a good video that shows step-by-step how to remove and replace the deck of a Z421 (ideally 60")? Thank you!

I tried and tried to let them let us make basic videos for this exact kind of thing. But no, they thought it would take from the dealers. They want people who can't do things to take it to the dealer all the time. I don't fully agree with it but whatever. The attorneys werent fond of it either (liability).

Put the height control knob as low as it will go. Let the deck down. Remove the belt from the clutch under the engine. Remove the pins that hold the deck to the hangers. push the lift pedal, to raise the hangers out of the way. Put the park brake OFF and release the hst's. Then put your foot on the trailer hitch, and your hands on top of the roll bar, and pull the roll bar down. The front of the mower will raise (or should) over the deck, you will feel it kinda balance. Turn the mower by hand so that it clears the deck and then let it back down.

reinstalling the deck is the exact reversal starting with putting the deck back under the mower, then put the lift arms back down using the lift lever, then put the pins back in, then belt, etc.

I live by myself and can't get a video for you. GF likes to do that kind of thing but she's a poor camera person, plus nobody wants to look at a short fat bald guy on youtube anyway so I'll spare you all.

Wouldn't it be easier to buy a mower lift? I know some Kubota mowers have an onboard lift feature already, or one cab be added as an accessory. I had to add mine, but it is a ZD1011 model.

I do have the mower lift installed but it doesn't raise much more than a foot. I also have a Harbor Freight ATV lift, which can get the mower up higher.
