Saturday after done work'n on kids cars, and 4-5 beers, get riding mower out to check over. Hosed off from munching last 3 weekends of fall. Completely covered in brown dust and chopped leaves. Beer. Drained old fuel. Put fresh in. Beer. Checked oil. Like new w/o gas odor. Changed last fall. Put battery in. Beer. Set choke and fired right up no probs. After little warm up, checked blade engagement. No probs there. Press accell pedal. Nothing. Change gear selector. Nothing. All the way into reverse. Nothing. Push mower up to driveway. Beer. Get floor jack and blocks of wood out. Raise up, place safty blocks, and look all over underneath. Nothing broken or out of place. Get back up, large swig of beer...and notice the shift lever is on LH side, not RH. That would be the deck hieght adjuster....
