I currently have mtd yardmansx2 and have changed the pulley size on the motor to run a slightly bigger pulley for the front belt,the vari-drive setup is not the best idea that they came up with ,but the one i have got going now is quite fast and is only set up to give people an idea what we can do here with crappy old rideon mowers.
I am trying to start racing here in darwin nt soon and the rear engine rover ranger mowers i have also are just set up with 6hp briggs and stratton go kart motors to also get people interested in it.
So far so good,the 14.5hp yardman hasnt burnt or thrown a belt yet so hopefully it will last until i finish my 22.5hp twin with peerless 700 trans on the spare mtd frame (as soon as i can get the other half to show me how to put photos on here i will) so as to help any one else in this crazy sport
Sorry if i rambled on ,but i am new to this whole forum thing but learning fast
