The Operator's Manual is on Sonny's website. Go to the main tractor page where you can see all of the different types of tractors, click on tubeframes, and scroll down to almost the bottom of the page. You will see a listing there for "18423 OM". The reproduction of some of the pictures isn't the greatest, but it does explain how to hook it up. Along with the parts manual, between the two of them I was able to put mine on my H14. The 18423 Operator's Manual covers both gear drive and hydrostatic drive.i need the owners manual not the parts manual sonnys only has the parts manual.
