I remember when my dad used to let me drive the family car up the driveway. Never had the chance to drive a bulldozer back in the day. Good on you and Heath!
First time I drove a loader, was just like that one. I was 19-20, already in dump trucks. Operator on the job let me play with it while he was doing something else. I Knew all the controls, but after moving forward about 30' I needed to stop. A Sudden Panic hit me, just for a second, but my mind went blank, thinking "How do I stop it"! I was ready to dig the bucket into the ground, when it came to me, Just stand on the steering brakes, & next I realized shit to Neutral! but that's what Panic does to you!
