Hybrid Engine for Compact Tractor

Hello!

I saw here few conversations in the past related to hybrid engines.

Is there anyone with experience in the manufacturing of fuel engine to charge a battery?

Or any company that you know able to do?

Mainly for light vehicles like garden tractor or similar (200Kg up to 400Kg).

I saw several applications related to drones but not much related to other applications.

Many thanks. Regards.
