Thank you for your input. This has really helped me a lot, and I really appreciate it.
I have located some cheap ESC on ebay, and I think this should work with DC775 motors with blade.
Now, based on your experience, what would be the best motor for my blades, instead of DC 12V 775 motors.
Should I got with brushless ones, and get ESC for those kind of motors, or do I stick with basic 775 DC 12 V motors and run them. What would be more efficient motors for blades?
I will use 12V 100Ah LiFePo4 battery with BMS and I think this should be more than enough for 3-5 hours of mowing.
Any input would be great.
