Dyrr tillage equipment

This is an offshoot of the Atlas plow discussion about a Stockton CA manufacturing company that built equipment pulled by caterpillar or other crawler tractors then became IH Stockton products plant. It was located on the north end of the San Joaquin County Fair.

I have seen it spelled Dyrr and Dyer.

Thank you CR:

I have some orchard ridgers made by Moore Equipment Co. or West Coast, which was before IH bought them out.

Interesting history nevertheless. Thanks! JM

Thank you for the digging up this history CR.

I know the dealer selling a brand could cover some short coming of the equipment it self, up to a point. From what I saw being used Dyer discs where number one in this area. There were Towner, Goble, Killefer, and Allis Chalmers discs in use in my youth. As a kid always wanted to pull the Dyer rather than the Towner that were the most used tillage tools we had. As the Dyer had a T shaped hitch, were the Towner was a A. Almost impossible to turn to short with the Dyer, always having to watch the Towner to keep the track out of the hitch on a short turn.

The Dyer hitch was built so the drawbar could slid right or left on the channel iron part of the hitch putting your tractor closer or father from the trees being cultivated.

Yes the Dyer could be easily offset to pull besides you under the low hanging fruit, you covered everything that the old timers loved about this design as well.
