Students in the Diesel-Powered Equipment Technology program at Tennessee College of Applied Technology Oneida/Huntsville have successfully restored a 1967 John Deere 3020 tractor to nearly original condition. The project included an extensive engine rebuild, hydraulic system overhaul, and cosmetic work, all performed in the school’s diesel shop on the Oneida campus.
Hands-On Diesel Equipment Training Included Engine Overhaul and Hydraulics Rebuild
The tractor was donated by Lee and Karen Little of Clarkrange, Tennessee. Prior to restoration, the machine had been unused for three years with a seized engine and deteriorated appearance. Under instructor Gabe Kennedy, students performed a complete engine rebuild — including new pistons, a replacement cylinder head, and a new camshaft — along with reconditioning of internal components. The hydraulic system was fully rebuilt, and the tractor was disassembled, prepped, and repainted to a high standard.
This project gave students real-world experience diagnosing and repairing diesel-powered equipment, mirroring the skills taught in the Diesel-Powered Equipment Technology program, such as engine systems, fuel delivery, driveline components, and hydraulics diagnostics and repair.

John Deere 3020 Key Specs and Tractor Features
The John Deere 3020 is a classic model from John Deere’s New Generation series, produced from 1964 to 1972. Known for its durability and versatility, it was a popular choice for row-crop farming and general agricultural work.
Typical specifications for this model include:
- Engine options: 4-cylinder gasoline, LP-gas, or diesel variants.
- Diesel displacement: ≈270 cubic inches.
- Rated horsepower: ≈70 HP.
- Transmission: 8-speed Syncro-Range with optional Power Shift.
- Hydraulics: Closed-center system with ~22 GPM flow.
- PTO: Independent 540 and optional 1000 RPM.
- Operating weight: ~6,500 lb.
These features made the 3020 both powerful and flexible for a range of farm tasks, and its hydraulics helped support loader work and implement operation.
Community Tribute and Public Debut
Originally intended as an engine rebuild assignment, the project expanded into a full restoration when students connected with the Littles. Their respect for the couple — long-time educators deeply involved with students — motivated the team to complete the tractor to a show-ready level. The restored John Deere 3020 debuted at the Scott County Chamber of Commerce Christmas parade in Oneida, drawing positive attention from the community.
