If it has Briggs & Straton engine you may can get a key at Lowes.DH picked a Lone Star tick off me a little while ago. That's the kind that gave GirlChild the red meat allergy. I don't think it was on me very long. DH ordered, and received a small riding tractor recently. Some assembly required. He got it all put together, ready to rock n roll, but ... no key included! He called them but it will be mid-month before they can send him a key. Meanwhile, due to all the rain, our 3+ acres of grass is getting to be, er, waist-high to a tall Indian! So the ticks are having a hay day.
