About Us


We would like to welcome you to Agri-Services, and tell you a little bit about ourselves. We're Jim and Sue Guarino, owners and founders of the business.  Since 1971 Jim (an Ag Engineer) has been doing farm service and custom farm field work. We own and operate a small hay and grain farm and are members of the Western New York 2 Cylinder Club. A few years ago our neighbor needed a John Deere D rewired, and we needed some round baling done. A trade was made, and since then, we have been providing restoration wiring harnesses through out the US, Canada, and abroad. 

Our harnesses are patterned from measurements of original harnesses and from measuring tractors at auctions and shows. We also research wiring diagrams, parts books and owners manuals to assure that our products are accurate. All of our terminals are crimped and soldered to assure a good connection.  Each harness is shipped with a connection sheet, which corresponds to numbered tags that we attach to each wire.  We use original type materials including cloth covered wire and rubber terminal insulators. Our trained technicians use braiding machines to apply a cloth or vinyl coated nylon braid outer harness jacket, as well as, cloth loom, tape or split loom to match the harness specifications. Our plastic covered wire is insulated with cross-linked polyethylene, which has a resistance to environmental stress, cracking, cut-through, ozone, solvents, and heat.

All of our harnesses are custom built, and can easily be made to fit tractors with modifications such as 12 volt alternator systems, regulator conversions, high performance ignitions etc.

Restoration of vintage tractors has grown tremendously in the last few years. Restorers spend a lot of time and money to bring a tired piece of farm machinery back to life. But when its done, you can step back and picture it being brought home from the dealer for the first time! Some of our customers even remember that day back when they were little. Tractors are being passed down from generation to generation. So if you should be passing by something that looks like a pile of rust in the weeds, check it out! It might be something you can pass down someday.
