Description
When your tractor won’t turn over on a cold morning, you need jumper cables that actually work. These heavy-duty 4-gauge cables are built with 100% copper wire that conducts power efficiently even in bitter cold weather, so you can get your equipment running and get back to work instead of struggling with flimsy cables that barely transfer enough juice.
What You’re Getting
- 500/600 amp peak capacity handles the high current demands of diesel engines and large tractors
- 20-foot length gives you plenty of reach without having to maneuver equipment uncomfortably close together
- Heavy-duty copper parrot clamps grip battery terminals securely and won’t slip off when you need them most
- 100% copper construction provides superior conductivity compared to copper-clad aluminum cables
- Tangle-free PVC cable coating stays flexible in cold weather and resists cracking
Built for Real Farm Work
These cables are designed to jump-start everything from compact utility tractors to full-size row crop machines and combines. When your John Deere won’t fire up after sitting in the cold, or your Case needs a boost after running the battery down with hydraulics, these cables deliver the amperage you need to get cranking.
Made to Last
Farm equipment batteries are tough to jump, especially big diesel engines in cold weather. The 4-gauge copper wire and heavy-duty clamps handle the high current draw without overheating or voltage drop. The thick PVC insulation protects the copper from moisture, chemicals, and the rough handling that’s part of farm life.
Good to Know
Always connect positive to positive and negative to a ground point away from the battery when possible. Let the cables sit for a minute before cranking to allow the dead battery to accept some charge. Keep the donor vehicle running during the jump, and don’t forget to clean any corrosion off the battery terminals for the best connection.
