hi im going to be makeing a very big tractor conversion im going to be using a kids pedal tractor and turn it into either a mf 3070 or a mf 8690 i will do some mesure ment and some drawing and see what will be better. my conversion will be very detailed with hopefully a working hand pump hydraulic system i was think to make it remote control but that would take a long time i might do that in the future to a battery 4+4 because that would be fun if anyone can supply me with blueprints of a 3070 or 8690 that would be very helpfull
