Avery patented cooling system, which with a round radiator open to the breezes from any direction, does away with a circulation pump. eliminates the fan and fan belts. The exhaust is piped so as to be emitted up through the round radiator, thus drawing in the cooler air from the outside with its rush as it blows up and away from the operator.
 The Avery duplex gasifier is the third feature. This is a little device on the head of each of the cylinders in the Avery tractor which turns kero- sene or distillate into gas and burns it clean. With this device there is no danger of liquid fuel passing through the cylinders and working down to the crank case to cut the Indication. The oil system for the Avery draft horse" motor is another feature. This system was designed to supply complete and certain fabrication to all parts of the motor which are oil tight and dust proof. The oil is pumped to the motor parts in an endless stream whether i there is a gallon pint of oil in the l crank case. It passes through glass chamber in plain view of the operator. This simple automatic Indicating sys- teh guards every part of the motor during every moment of it's operation and keeps it deluged with lubricating oil as long as it is in motion ! 1 bearings is the fifth feature. They are simple easy to take up with the aid of an ordinary wrench and without re- moving single part from the motor and requiring but a few seconds time. | Can be accomplished in the field or anywhere should such adjustment be necessary. By adopting the opposed l type of motor in the Avery tractor this 1 style cd adjustable box could be em- ployed because the motor is narrower, therefore, does not call for excessive width in the tractor and makes pos sible the two-bearing crankshafts. which is the only kind that can thus be made adjustable. A three or five bearing crankshaft could not be pro- vided with this device, neither could a vertical motor. as vertical motor calls for excessive width in the con struction of the tractor, or of front mounting of the motor with excessive weight on the front wheels, also driv- ing through q beve1 gear. which causes end thrust, under friction and loss of power.
 Feature number six is renewable in ner cylinder walls which provide the system of manufacturing a tractor mo- tor whereby the cylinder walls may be cast independent of the cylinder of much harder material and therefore capable of withstanding greater wear than the ordinary cast enbloc type
 
 which any one of the cylinder walls may be replaced at a moderate cost in the field by ordinary operator by simply removing the cylinder head. 1T for any reason it becomes worn from years of use. No time has to be lost sending the motor to the repair shop or the factory. and new stand ard size cylinder wall and standard size plstons will make the wearing parts of the motor as good as new any time, all of which may be accomplished without the aid of a service man. and the farmer may do it himself at very small cost. Thus any Avery motor after working for years may have it's wearing parts renewed, the motor re- energized and made as efficient as the new product.
 The seventh feature is the Avery universal self-cleaning wheel lug which holds the wheel from slipping on soft fields and plowed ground, on slippery roads or sandy land: neeo- tiates hard roads without jar and pre- vents side sloughing of the tractor by reason of the straight part next to the inner rim of the wheel, and is superior to any other type lug. The impres- sion made in the ground on account of the shape is not disturbed as the wheel lifts it from the soil It comes out easy and natural wheel slippage being prevented.
 The above features in a tractor make tractor enjoy long-Iife and also make it easy for the owner of the tractor to be able to not only operate the machine efficiently bu. also 10 repair, renew or adjust any working part himselft right at home. in his fields, or machine shop. The aim in design of Avery tractors is to enable owners to farm with them at q profit.
