In 1969, a farmer from Reinbeck, Iowa by the name of David Bystriki, approached Jon to inquire about re-powering his 5020. ...Jon took on the challenge. And so the 5020 Kinze Re-Power was born. Jon Kinzenbaw was a 25year old innovator operating a welding shop in Ladora, Iowa in 1969. He had developed a good reputation for his ability to fix or build anything. He had already built his first unloading auger grain wagon, his first payloader and first high-flotation chemical applicator. His fabrication skills knew no limits and Jon would tackle any project that came through the door.
The JD 5010 came out in 1963 and was followed by the 5020 in 1965. The two shared the same basic engine but the 5020 had been cranked up through the pump to give it an additional fifteen horses. Even at 141 PTO horsepower, the 531 CID Deere engine needed more. For many power hungry farmers, they turned to M&W Gear to add a turbo. However, the 531 wasn’t designed to be a turbo-ed engine and they didn’t
last. The most obvious choice was to re-power it. In 1969, a farmer from Reinbeck, Iowa by the name of David Bystriki, approached Jon to inquire about re-powering his 5020. Still operating out of his first welding shop, Jon took on the challenge. And so the 5020 Kinze Re-Power was born. As you probably know by looking at the pictures, the Kinze re-powered 5020 was accomplished using an 8V-71
Detroit. One of the most frequently asked questions is “why did he use a screaming Detroit?” There are several reasons. In the 1960’s the 71 series Detroits were very popular and reliable. They were widely used in the trucking industry making them plentiful in large quantities. The exhaust temperature on the 531 was 1200-1300 degrees while the Detroit was less than 700 degrees, which resulted in a greater life expectancy. And probably the most logical reason it was used was because it fit inside the engine cavity of the tractor and overall dimensions after installation were identical to the original engine. It provided compact horsepower with minimal modification.
