Hey Fred,
995 Lugmatic is correct, we need more to go on, most models could have a crank. A picture here could be worth a thousand words. If you can get some digital photos, there is a way to post them here, I don't know how. Contact Chris Losey, our webmaster, he would be happy to explain how you can post them. By the way, make sure to brag on Abby, she is Daddy's little girl, and cute as a button, especially when she is checking us all out at meetings. Amazingly, she is well behaved.
Getting back to the subject, there were several locations for serial number tags. Look on the right frame rail, near the foot rest on early HG's, later ones, and OC-3 should be on the bellhousing. HG's are notorious for having missing tags, the location is subject to all kinds of contact that would tend to tear them off. If your model has a firewall, it is likely you will find the tag somewhere on the engine side of it, generally high up, and covered up with dirt and oil. I have seen some that I really needed to hunt to find, couldn't tell where to look for all the dirt. I have a power washer that does a good job of finding those, when I can get close enough to a water hose to use it. The good thing is on these models, the dirt and grime kind of protects these tags, once well cleaned they normally are in good shape and easy to read.
Get me some serial numbers for the tractor, not the engine, only the tractor number will cross over. There should be a tag on the engine also, but it only relates to the engine, and will not help in identifying the tractor. Separate manufacturers. A good picture or pictures are the best starting point. I hope this helps.
Take care!!!
