WITH the object of setting on foot IT a movement to secure some standardization of pneumatic tyres for farm tractors and implements, a conference of interested bodies was organized by the Tractor Users Association, in London, on Tuesday.
The chairman of the Association, Mr. D. N. McHardy, stated that his organization was providing facilities for carrying out the work proposed to be done by the Power Farming Development Board, which had been dis cussed in London in April. This would obviate making fresh arrangements for a new body.
Dr. Alexander Hay, of the Rubber Growers Association, said that, in the United States and Canada, there were at least 21 sizes of rear tractor tyre and 10 sizes ot front tyre. A similar state of affairs was becoming apparent in this country.
One of the advantages claimed for pneumatic tyres was the use that could he made of the wheels for various pur poses and the extent to which it was possible to interchange wheels between different types of equipment. In this country we had used the 11.25 by 24 rear tyre for all-round work on the farm, but in America there were five sizes of tyre in service For row-crop tractors, six tyre sizes were provided, of which the most popular is the 9.00 by 36. Here, again, there was scope for further collaboration in order to ascertain Which sizes were most suitable for British conditions, The use of the land tyre for binders, combines and other equipment was increasing and there was a large range of new tyres available for implements and machinery. The farmer was, therefore, supplied with a range of implements, the wheels of which might not be interchangeable. The conference should establish a means for dealing with the whole problem to the mutual benefit of the manufacturer and the farmer.
After a discussion in which tyre sizes and behaviour were reviewed, the conference appointed a small group of members to take up the work of putting into effect the suggestions made. Its address is care of Mr. P. G. Cambray, Secretary, Tractor Users Association, 66, Victoria Street, London, S.W.!.
It was announced that a conference on the training of agricultural-machine operators would be held at the beginning of December. The date and place will be announced in due course,
