MOTOR TRACTOR TRIALS. 



The Royal Agricultural Society of Victoria, in connexion with the Annual 

 Show, September, 1918, arranged for a series of trials with motor tractors. 

 The Field Ploughing Tests were held at the State Research Farm, 

 Werribee, during the week before the Show, and the tractors were subjected to 

 further technical tests at the University, Melbourne, after the Show. Mr. 

 William Ross was appointed to report on the ploughing and an Engineers' 

 panel, comprising Professors Payne (Prcfessor of Engineering), Mr. \\ . N. 

 Kernot (Lecturer on Engineering), and Mr. E. J. C. Rennie (Lecturer on 

 Agricultiu-al Engineering), was appointed to make the necessary observations 

 and report on the technical points. The report to the Society is as under, 

 and deals with the following : — 



1. Ploughing Performances — ■ 



(a) Fuel consumption test. 



(6) Dynamometer test. 



(c) Mr. William Ross's report on ploughing. 



2. Engines' Performances — 



(a) Normal load test. 

 (6) Maximum load test. 



3. Description of Tractors — 



As the conditions under which the trials were to be conducted 

 was that the competing tractors were not to be placed in 

 order of merit, the judges herewith present the full results 

 obtained from the various trials. 



1. Ploughing Performances. 



(a) Fuel Consumption Test. 

 Tests were conducted at the Government Research Farm, Werribee, on 

 19th and 20th September, 1918, for the purpose of determining efficiency of
