18-36 GHart-Parr was great at advertising there tractors in non-stop plowing merathons. One instance was in Australia plowing for 11 staight days, a world's record. The 18-36 was usually the tractor of choice for these demonstrations. When the 18-36 appeared on the market it was basically a model 16-30 with a slightly enlarged engine bore, now at 6.75 inches. This extra quarter inch larger bore gave this tractor a real boost in power. The model G still had the short fenders, but it did sport the winged decal and winged radiator cap. Although some early models had the screw in radiator cap. Some model G's came equiped with round spoke wheels both front and back.
18-36 H and I
The model H and I have very little visible differences, but there are some basic differences between
the model G and the H and I. Appearance wise the model H sported an oval fuel tank holding 12 nore gallons of fuel
to operate that larger engine. Also the fenders came down to the platform floor boards and the platform
was slightly enlarged. The biggest major improvement was the addition of a 3 forward speed transmission. This
gave more operating speeds and got the job done more efficient. Flat spoke wheels were added in 1929, but
fronts most often remained the heavy cast type.
These tractors are easy to work on and sound similar to a two cylinder John Deere. The 18-36 was the most popular tractor built of the lightweight models. Most Hart-Parr collectors want to collect all three models of the late style tractors, the 12-24, the 18-36 and the 28-50.
