Micro Mini tractor pulling is 45 years old

The first one was built by Richard Polley,a machinc in a a Oliver tractor dealership in Missouri. They pulled it on a concrete floor in the shop. That was in 1973 and some way guys from Ertl in Dyersville,IA started pulling them on a bar in the bar top. The National Micro Mini Tractor Pullers Association was formed in 1976 in Iowa and is still operating across the USA today.He

Mine were built in Ohio on 1/16th Ertl tractors in the mid 70s. The basic tractor cost somewhere around $135.00 top photo. They were powered by a Cox TD .49 engine that turned 22,0000 RPM.

I have wanted one of these for years . Now I torn between one of these If I could ever find one or a wliesco live steam traction engine

Son and I raced what they called GAS R/C cars years ago, fuel was 20 to 50% nitro-methane and alcohol,
normally methanol, and about 8 to 10% various types of oil for lubrication, some castor bean oil, couple
different types of synthetic oil. Fuel would run a Cox .049 cubic inch engine great. Brand of fuel Son
had best luck with was Byron Fuels made in Ida Grove, Iowa. We used OS Engines at first, .12 cubic inch
displacement, later switched to a TOP engine from Italy, it ran like a striped APE, close to TWO
horsepower at 35,000 rpm. SON raced 1/8th scale 4WD buggys for lots of years, .21 cubic inch engines, was
a sponsored team driver of REDS RACING Engines, some versions approached 4.0 hp at over 40,000 rpm.

Just imagine what those engines would do in a 1/16th scale diecast tractor. I've got a freshly rebuilt
.129 cid OS CV engine out in the shop that I would love to install in a tractor. The .21's are just too
much power.

The RC club we belonged to about 20 years ago had an electic powered truck pull at our New Years Eve
party. Guys just hooked several 7.2V battery packs together and buzzed the motors to crazy high rpm, what
they pulled seemed to be directly related to their total weight.

There's hundreds of hours of videos on U-Tube of cars, trucks, tractors pulling weight transfer sleds.

Back when we pulled we used a fuel that was made by Cox and also used missle mist in engines. After I quit they started using nitrous.

Thimble Drone .049 cid. I had a couple control line airplanes. I got tired of the short run time on the last one, fuel tank the size of a small thimble, so I glued plexiglas onto the whole fuselage, increased fuel capacity 5-6 times as much, but too much weight to get off the ground, needed more speed, more prop. Found a hobby shop, got a much more aggressive prop and the plane nearly jumped off the ground, and ran and ran and ran and ran..... It finally ran out of fuel glided to the ground and landed and fell over I was so dizzy!

The R/C boat guys are just beyond CRAZY what they do with their engines. Weak link of the engines is the big end rod bearing, or more correctly, bushing. You over rev the engine and you spin the bronze bushing in the rod, and wear away the rod till it fails. Boat guys typically use up a conn rod every run, a .129 cid car engine can burn over a gallon of fuel between rebuilds. A boat engine maybe burn 2-3 ounces. Car engine will make +/- 1 hp at up to 38,000 rpm, boat engine over 2 hp at 50,000 rpm. Car engine uses big machined aluminum head with lots of fins, boat engine circulates cool 0pond water thru the head. Car engine tuned to idle, rev cleanly, and make decent top end HP, boat engine tuned to make maximum RPM.

We had about three different size fuel tank that would fit them. The fuel tank was behind those four screws on right side of tractor.

Been collecting these for years and still looking for more call
me if anyone has them for sale 5073838189
