Tractor Power
SIR,—Your contributor in.Country Life, December 7th, makes this state- ment: "A light Ferguson tractor would obviously have been far the better implement against packing [the soil], but like horses would have lacked the drawing power." Permit me to correct him and explain why the light Ferguson tractor has, in the short space of five years, become popular to the extent that it accounts for 52 per cent; of U.K. production. Basically, the secret is that the plough and the soil flowing over it provide the necessary weight for wheel grip. We would agree with your con- tributor that weight is necessary for wheel grip and that weight packs the soiL Moreover, built-in weight is a great waste of fuel. The bigger the tractor, the more weight is being carried for the sake of wheel grip. When full power is not required—as on most farm work—the waste of fuel goes up almost in proportion to the ballast weight—Yours faithfully, A. B. LEES,
