I get my help from this years graduating High Schoolers looking for temporary work. The quickest way to train them to use a Hustler walkbehind, for me, has been to let them first use the machine in a wide open area. They, like me, though the controls too responsive, and, at first over corrected. After using the machine, on their own, [with a through indoctrination of the H-bar system] I then get them to place their hands on the controls in the normal operating position, while I operate the machine using the very end of the hand grip. At first we start out walking, making turns, backing up. Then I speed things up a bit, running along side, [like when I learned to ride a bike] making tight turns, forward and reverse motion, etc. and then just letting them go. If the person has good common sense, he can roll with it in under 5 minutes. They think using the machine is "da bomb" after that. Problem is they don't want to go back to weed eating! The H-bar system, and the responsiveness of the Hustler walkbehind, have added the phrase "fun to use" to my operation. You can see it in their expressions when they use the machine. For me, it increases my productivity, for them, its more like having fun than hard work. I can agree with that.
