How Many Acres Per Hour?, J G. Drever
Journal of the Department of Agriculture, Western Australia, Series 4
MANY farm tractor operators don't know exactly how much land is covered in an hour by implements drawn by their tractors. This information, useful on any farm where tractors are used, is of particular value in contract work.
The capacity of the machine or implement, or in other words, its rate of working, depends on the width of the machine, how fast it travels, how efficiently it is operated and the time it works.

THE Massey-Ferguson MF-135 is a general purpose tractor of 31 drawbar horsepower. It has 14.9 x 24 pneumatic tyres, and a three-speed gear box with a ratio change which, in the standard model, gives six forward and two reverse gears.
The model tested was also fitted with the optional "Multipower" facility, which gives an "on-the-go" shift to a higher speed for each gear, thus providing 12 forward and four reverse gears.

THIS Report is taken from the full Technical Report No. 36; results are shown here in briefer form: fuller explanations are added.
Values quoted may be rounded out to two instead of three significant figures; to this extent the values may differ slightly but not significantly from those shown in the Technical Report.
