i have been wanting to see how my max 2 highboy performs with the half tracks on and rear chains removed . did it this afternoon . it definately turns better (on a dime ) and has as much power as no tracks on . seems to pull better in deep mud .. have'nt noticed the middle drive wheel spinning in the track yet . if so , a bit more air in the tires ..as the tracks are'nt real tight at all . always fun trying different things with these machines . jboy va.:
