Hi Jim, the lawn looks great mate.... at getting your machine up and running....just set the throttle to achieve a reasonable engine speed, it doesn't have to run flat-out; engage the cutter-clutch and gently squeeze the drive clutch handle until the mower moves across the ground at a comfortable pace that suits you.
