I have a 2018 Z421. I broke the lever safety switch by laying on it trying to hook up gas line.
After that it would not start. I can hear the Bosch relay clicking, but nothing happens.
I have replaced
The safety switch I broke.
The ignition switch.
The starter relay.
Both Bosch Relays.
And the 30amp slow blow fuse was burnt out. Replace it.
Battery is hot, and when I short across the relay terminals the motor turns.
Kubota dealer wants $200 to trouble shoot.

Are you 100 sure you put the wiring on the new safety switch exactly like it was on the old one ? Also check the wiring on the new relay as well. Do you have access to the wiring diagram for your specific machine ? In the future, before taking any wiring apart, take nice clear pictures of the existing wiring with your phone before replacing any parts. It might save you a lot of headaches. Also check both sides of all your fuses with a test light to make sure none are blown and need replacing.
