20 Horse Gear Drive?
 

First time post. This is a fantastic site information-wise.

Under either the International or MTD banner, did they manufacture a wide or spread frame tractor with a 20 horsepower engine that was gear drive, not hydro?

If so, what model was it and what engine did it have?

Welcome to OCC

As far as I know the 1535 would probably be the highest HP gear drive. It was rated at 15HP but supposedly it was actually 18. I'm sure others with more knowledge will chime in on this one.

Sam the 1806 was a 18hp magnum gear drive with a creeper. They are a pretty rare bird.

YUP, and there is nothing to say one couldn't drop in a M-20 in the 1806 too.

This is from tractor data

Kohler
2-cylinder air-cooled
691 cc [42.18ci ]

Idle RPM: 1200-3600

1806
Kohler M18
2-cylinder air-cooled
691 cc [42.18ci ]
Bore/Stroke: 3.125x2.75 inches [79 x 70 mm]
Power (gross): 18 hp [13.4 kW]
Idle RPM: 1200-3600

Think it's the same deal as the 1541 with the Mag18 that they called a Mag15. Interesting topic. :bigthink:

This is from the service manual. Looks like the 1535 is just a Cyclops version of the 1806 to me.

Yeah, We seen it before. They take a 18HP engine and de-tune it (Carb) and make it a 15HP engine.

Both those tractors are pretty rare.

The 1535:
*Last 3 speed trans GT made by CCC.
*Only gear drive Cyclops

Thanks for the replies and I looked through the Repair Manual for these machines and see it was available in both gear (1806) and hydro, the hydro being an 1812.

Thanks again, my question has been answered.

I found this one to be interesting. I've never paid any attention to the later gear drive stuff. Now I want one. Love to find a 1535 with a blown engine and drop a CH22 in it.

Mechanic why do I think your planning on building something cool? :bigthink:
