Hatz tractor

2715 E. Birch Run Road Burt, Michigan 48417

I acquired this Hatz tractor from my cousin, Dick Woodward, who purchased it from someone who knew only that it came from northern Michigan. I have talked with many collectors recently, and no one has ever heard of a complete Hatz tractor.

It is a mystery as to how this tractor came into this country, as you can determine from information in letters from Hatz representatives inquiring about the tractor.

A letter to cousin Dick from Motorenfabrik Hatz, GmbH & Co., KG, 8399 Ruhstorf/Rott (the German manufacturers of the tractor), reads as follows:

'Thank you very much for your letter of June 8, 1978. We were pleased to note that you are the owner of a Hatz Z 90 tractor, built in 1960. Could you, perhaps, let us know at your convenience through which channels this tractor came to Birch Run?

'As requested, we are attaching hereto an instruction booklet as well as spare parts list for the engine type Z 90; for any further questions re spare parts or repair advice, please contact Hatz Diesel of America, Inc., 2867 So. 160th Street, New Berlin, Wisconsin 53151, who will be gladly at your disposal. Signed C. Steppacher, Export Manager.'

Upon writing to Hatz Diesel of America, my cousin received the following reply, dated October 31, 1978:

'Manuals are no longer available. Certain parts we may be able to match up. As you may know, this tractor was not originally meant to be sold in the U.S.A., so you can imagine our surprise to find one in this country. Sincerely, Keith Kichefski, Service Department.'

I believe this may be the only Hatz tractor in existence in the U.S. and thought it would be of interest to you. The tractor has a two-cylinder, aircooled diesel Hatz engine and runs very well. Some other important details you may notice in the photographs are: some type of spring loaded shocks on the front axle, 3-point hitch, V-belt pulley, front PTO, live PTO 540 rpm in rear, differential lock.

I do hope you will enjoy looking over these photographs. I took the tractor to the annual Mid-Michigan Gas Tractor Show in Oakley, Michigan and found many people interested in it. Not one person has ever heard of it. I'm hoping perhaps you'll lead me to more information about it.

Hello, after 22 years it might not interest you anymore, but your tractor is a Hatz TL17, and Z90 only is a number for the engine. Gear-No. should be HURTH G819 All the best, amelio
