They Don't Make Tractors Like They Used To!

| July/August 1972

Rt. 1, Box 147 A, Suisun City, Cal. 95485.

Can you begin to get an inkling of power, friction power at belt, and drawbar? A 30-60 tractor is a very big machine. Has anyone wondered what happened to all that power between belt and drawbar? Friction takes a 50% bite. But, one thinks, a transmission has ball and roller bearings as antifriction devices. Big deal! Does anyone remember the Fordson owner who wrote, 'Fordson worm drive could get so hot, one could fry an egg on it!' Gear teeth are fairly efficient.

Notice in IRON-MAN ALBUM that 60 II. P. steam engine has only 20 H.P. at drawbar. Those plain bearings chew up power faster than gas outfits. A farmer may snap his suspenders and proudly exclaim, 'That's a 30-60 tractor.' If its 60 years old, don't you believe it. If it has done years of hard work, a compression test will show how much H. P. is left.

When you hear, 'They don't make tractors like they used to,' this is partly true. Big bore and stroke engines seem to last forever. Our modern diesels wear out, and have replaceable sleeves. Mini cars replace motor block; V W's replace cylinders, pistons, rings, heads. When diesel has 1/16' between piston and cylinder, it won't start. Don't take my word for it. This was head of Allis Chalmers tractor research department, at Davis, California, just before we saw movies of their experimental, butane-fired, fuel-cell, electric drive tractor. How come it never sot on the market?
