The 1980 John Deere 4440 stands as one of the most respected tractors ever produced. As part of the legendary 40 Series, the 4440 helped define an era of dependable row crop tractors that farmers could trust day after day. Built in Waterloo, Iowa, it featured a powerful six-cylinder diesel engine, a durable PowerShift transmission, closed-center hydraulics, and the iconic Sound Guard cab that set new expectations for operator comfort. Decades later, the 4440 remains a favorite among both collectors and farmers who value proven design and long-term reliability.

What makes this particular 4440 special is the extensive restoration it has received. Showing just over 8,000 original hours, this tractor has had more than $43,000 invested in a comprehensive rebuild and service process. The restoration included new fluids throughout, replacement of seals, bearings, bushings, belts, and hoses, and updates to the heating and air-conditioning systems. The final drives were removed and inspected with new bearings and seals installed, and the load shaft was fully serviced. A complete transmission rebuild, including the PTO, was completed prior to purchase, and dyno testing showed the tractor producing 176 horsepower. The documentation that accompanies this machine is extensive, with service records that speak to the level of care and attention it has received.

One of the standout aspects of this restoration is the inclusion of a John Deere Legacy Inspection performed by a John Deere dealer. A Legacy Inspection is a thorough, dealer-performed evaluation of the tractor’s major systems by factory-trained technicians. This type of inspection focuses on the engine, transmission, hydraulics, cooling system, electrical components, and overall mechanical integrity. The goal is to identify potential issues early and confirm that the machine meets John Deere performance standards. Having this inspection completed adds another layer of confidence for buyers, knowing the tractor was evaluated by technicians with deep product knowledge and access to genuine John Deere parts and diagnostics.

Following the inspection, several thoughtful upgrades were added to enhance both functionality and comfort. A third-function joystick was installed by John Deere, making the tractor more versatile for loader and hydraulic work. The rear tires were replaced with brand new radial traction tires that still show their mold marks, along with new front tires. Full LED lighting improves visibility, while a Bluetooth radio modernizes the cab experience. A skid steer-style loader adapter plate was added for compatibility with modern attachments, and the wheels were powder-coated to complete the refreshed appearance. Dual wheels round out the setup and reinforce the tractor’s ready-to-work stance.

This restored 4440 is being offered by Thunder Valley Truck, a seller known for commitment to quality and integrity. Their reputation is built on accurately represented equipment and a focus on bringing dependable machines to market. That approach aligns well with a restoration of this caliber.
