I have a 1974 case 224 s/n# 9667441 with a Kohler 14 HP model# K321A spec # 60207d s/n# 4335196 engine. I'm looking for a reliable IPC and maint manual so I can get the proper part numbers to order parts, and I read that a Brian Hildreth is the parts guy on these tractors but how do I get in touch with him. By the way I'm new as of today and can't wait to re-wire it and get it running. Thank you!!!!
