Today I connected the frame of the mower to the chassis and I started with some parts for the cab:
The drive motors for the front wheels and the mower discs are already ordered. For the discs I´ll take 2 brushless motors (12 Volts, 31000rpm) with a belt transmission to the discs (ratio 3:1).
The next parts to be ordered will be the tothed belts and pulleys for the discs.
