Just wanted to thank everyone who replied to my posts over the last several months regarding this mower. I found it in the basement of my grandparents barn. From what I was able to determine, it is a 1956 Lawn Boy 7000. The engine was stuck and it was covered in 40 years of agricultural dirt. It took some effort to remove the piston from the cylinder even after soaking it in diesel and numerous solvents. The bracket on the left front wheel is a modification. I'm assuming the portion of the deck that included the holes for the wheel adjustment snapped off and my grandfather had someone make the bracket to bolt onto the deck. I still need to buy smaller pop rivets so I can reinstall the emblem that goes into the circle at the rear of the deck. I've included some before and after pictures. If anyone is in need of aftermarket decals, there is a gentleman on eBay who has a large selection and can make others if needed. Hope you enjoy, and thanks again.
