Yazoo Master Mower / YR Commercial Rider – History


More than just a mower, the Yazoo has become legend among family and friends.

Below is a brief history I have compiled on the company through a web search. If you have any other information you think should be shared about these machines, or live near the Northern Illinois area and are looking to sell your Yazoo equipment, email your information to yazooinfo@musschoot.com

Sometime between 1942 and 1943, James A. Kerr, Sr. began a family business calledĀ Kerr Tire and Rubber Company, . The business developed into several separate companies and divisions including, but not limited to, Yazoo Manufacturing Company, Inc. (YMCI), Yazoo Sales Company (YSC), Yazoo Sales Eastern Division2 (YSED), Kerr Enterprises, Inc. (KEI), Master Sales Company, Inc., Auto Electric and Carburetor, and Yazoo of Texas.

The Yazoo Mfg Company was founded in Jackson, Mississippi in 1945 by James A Kerr Sr and remained in the Kerr family until 1981. The YR had a unique gearbox that allowed instant forward to reverse and near zero turn capability – years before the availability of hydrostatic systems. The YR was simple to operate and maintain. Built in the factory in Jackson, Mississippi, the YR had a choice of sizes and power units.
Here is a video of the Yazoo Commercial Rider:


Yazoo was also famous for their Big Wheel line of heavy-duty push mowers. What set these mowers apart was the larger wheels and the fact that the mowing assembly was driven indirectly with a belt to absorb the shocks and protect the engine.
Here is an original dealer promo video for the Big Wheel Mower:

James Kerr, grandson of the founder, is now in Melborne Australia producing lawn equipment under the name Red Roo.

Here is a video produced by the Red Roo Company with some historical pictures, and features the Red Roo version of the Yazoo Big Wheel Mower.

      Finding parts for these machines is getting tough. As the models vary, I do not know exactly the belt you might need. I have found some success searching ebay. A manual is attached to this page which may help you.

    I have always wondered why he named the mowers “Yazoo”. I’m from Yazoo City, MS, which is about an hour north of Jackson, MS. Did he name it for Yazoo City? Just curious. Thanks!!

    I just purchased a YR-60 with a 23 hp Kohler motor. The one I have has the 60 inch mower deck that is driven with a PTO shaft. Any idea what year they went to the PTO shaft verses belt drive. And does anyone have any links to repair manuals or any other online information that includes part lists for this model?

      I don’t have any information on those generation of mowers… just the old stuff. Check ebay… it is surprising what you can find on there.
