Cletrac had a long history dating back toand was one of the pioneers of the track type tractor industry. The Model F was a small crawler tractor strictly speaking only suitable for agriculture and weighed around kilograms, but could pull a 3-bottom plow with no trouble. It also allowed a higher than usual amount of ground clearance, making Cletrac machines especially popular with logging and forestry contractors as they could pass over stumps and brush that could potentially bring other tractors to a very sudden stop!

Other track tractor manufacturers took a long time to duplicate this method of undercarriage attachment with the first to successfully adopt it being Euclid in the mids.

When Oliver took over the Cletrac tractor range it consisted of some 12 different models, some gasoline powered, the others diesel. Oliver kept the Cletrac name, marketing them as Oliver-Cletrac so as not confuse the buying public and it was business as usual. Init was decided by Oliver management, to add some clearer structure to the model numbering system, better reflecting the sizes of machines offered.

Oliver as a company did not expend great amounts of research and development money on its OC track tractor range. White continued to operate Oliver as a going concern but was also reluctant to spend the large volumes of cash required to update the Oliver track type tractor range. The end result was that inproduction of all Oliver track type tractors was discontinued, the company preferring to concentrate on agricultural wheel tractors.

The Oliver OC was the largest track type tractor that Oliver ever produced and sat between D7 and D8 size in the track tractor world. This engine was a 6-cylinder inline diesel putting out flywheel horsepower and had a A double plate clutch connected the engine to the 4-forward, 2-reverse speed manual transmission which gave the machine a top speed of 5.

Oliver was unique in the American track type tractor market by using differential steering rather than the traditional steering clutch and brake method. Cletrac had pioneered the use of differential steering decades beforehand and it was carried over into the OC range of machines.

A good spotting feature of the OC was its long front hood, the rear part of which housed the 66 gallon diesel fuel tank. Oliver supplied its larger crawlers with a distinctive opposed chevron design radiator guard and the OC was no exception. The operator had an excellent view to trailed equipment as there was no fuel tank to look over.

However, the view forward was a long one and the hood did not feature any taper. Operator comforts were very few other than a deeply padded seat and air-boosted steering levers to reduce effort.

This was an unusual feature for a track type tractor and something that set the OC apart from the competition. Full instrumentation was provided on a semi-circular instrument panel in the centre of the dashboard. Oliver did not make its own attachments and relied on outside suppliers to provide bulldozer blades, rippers, cable controls and the like to equip the OC for service.

Principal suppliers were Heil, Isaacson, Buckeye and Carco with the most predominant of these being Heil. Regrettably, no records have survived from this company to give any indication as to how many Oliver OC track type tractors were imported including if any OCs. There were certainly a great deal of the smaller Oliver OC tractors brought into New Zealand however, and these proved to be very popular, especially in the South Island.

There is however a remarkably good model of the smaller model OC available from Spec-Cast. Facebook Twitter Instagram Pinterest Youtube.

By Richard Campbell. Background Cletrac had a long history dating back toand was one of the pioneers of the track type tractor industry. One of the hallmarks of Cletrac tractors was their reliability, especially final drives. This was due to the way the track frames were mounted to the chassis by way of a dead shaft. Using this method, no impact shocks were transferred through to the final drives.Powered by a cid Hercules WXLC3 engine driving a 4-speed transmission, the vehicle is capable of attaining speeds up to 22mph when the high rpm range is unlocked on the governor, allowing the engine to achieve 3, rpm.

With the governor set at 2,rpm, speeds up to 15 mph can be attained. In this way, power is always being transmitted to both tracks making the steering action smoother and improving safety on steep slopes.

Instead, the minimum turning radius is While this was a disadvantage for bulldozers, the controlled differential did prevent the tractor from tearing up pavement and turf, keeping the surface smooth for aircraft operations. Some testing was done to determine the suitability of the M2 as a gun-towing tractor, but it was quickly determined that it lacked the space to support the gun crews and carriage of ammunition and, as a 7-ton class machine, it was too light to pull the heavier howitzers and was eclipsed in this role by the M4 ton HST, M5 ton HST, and the M6 ton HST.

However, with rubber tracks that were suitable for use on paved surfaces as well as grass and mud, the tractor performed well on the primitive airfields that were common in forward areas during the war.

The psi tap was used for powering air tools, while the higher pressure sources were for charging the aircraft landing gear oleos. Special thanks to Mark Van Klavern for all the photographs!
