Mowing Kubota Zero ZD1511 stopped, "b" error light, will not start

[megiste]

Have a year old Kubota ZD1511, 130 hours, well maintained. Stopped suddenly after mowing for one hour. REGEN light on, "b" error code, will not start. Brake seems fine, clean. I have been reading that a "forced REGEN" (?) may be necessary but that requires a running engine. REGEN has been working fine, usually while I am mowing with no other issues.

Any thoughts?

On my L6060 Kubota the regen requires a high RPM. I dont remember what the magic number is but are you running your machine at a high RPM for the regen?
