Description
When you’re building or rebuilding a PTO driveline, having the right tubing on hand saves a trip to town when you need it most. This 7/8-inch square tube gives you six feet of precision-formed steel to create custom driveline connections between your tractor and implements. Whether you’re shortening an existing driveline, making repairs, or fabricating something from scratch, this tubing handles the torque and keeps your power flowing where it needs to go.
What You’re Getting
- Precisely formed 7/8-inch square cross-section that fits standard driveline components
- Full 6-foot length gives you plenty of material for most projects
- Heavy-duty steel construction stands up to the twisting forces of PTO operation
- Clean, smooth finish makes welding and machining easier when you’re fabricating
Built for Real Farm Work
This tubing is the backbone of driveline systems that connect tractors to everything from rotary cutters and hay balers to manure spreaders and feed mixers. The 7/8-inch square profile is a common size for lighter to medium-duty implements, giving you the strength you need without unnecessary bulk. If you run implements that take a beating—bush-hogs, tillers, or anything that sees rough ground—having spare driveline tubing around is just smart planning.
Made to Last
Driveline tubing takes some serious punishment, with constant rotation, shock loads, and the vibration that comes with field work. This steel tubing is built to handle those forces without work-hardening or developing stress cracks. The square profile distributes loads evenly and resists the twisting that can cause round tubing to fail over time.
Good to Know
This comes as raw tubing, so you’ll need to machine or weld it to fit your specific application. Most driveline work requires proper balancing after assembly, especially on longer shafts or high-speed applications. If you’re not set up for this kind of work, your local machine shop can help with the fabrication while you supply the quality tubing.
