Your advice worked perfectly - thanks a lot! I discarded direct drive option early on because
rear wheels of my mower are 14" in diameter - slightly to big to be driven by 160 rpm motor. After
reading your e-mail yesterday, I started playing with 7" front wheels, which I cut out a few days
earlier and guess what?! These wheels interlock perfectly with slots on weird hub PowerWheels
motors have, moreover I was able to use height controlled mount for this powered wheel assembly.
I'm planning to conduct some driving tests soon. Thanks again.
