Draft requirements for prototypes of mouldboard plough, cultivator and offset disc harrow
with different widths of cut or number of tools were measured at four levels of depth and four
levels of forward speed in three soil compaction levels in a soil bin with sandy clay loam soil
at an average soil moisture content of 9.58% (d.b.). Effect of depth was more significant on
draft of mouldboard plough and offset disc harrow, whereas number of tynes was the most
significant factor for cultivator. Rate of increase of draft with respect to depth was higher
as compared to forward speed, cone index and width of cut for all implements tested. Draft
values predicted by ASABE model were compared with those obtained from soil bin tests at
three compaction levels. Quite often, the measured draft values were found to be about 2.9,
1.7 and 1.65 times more than the ASABE predicted values for mouldboard plough, cultivator
and offset disk harrow, respectively. An equation similar to the ASABE model incorporating
cone index was developed using stepwise regression analyses to model the draft of tillage
implements for the range of soil and operating condition tested. Field tests with commercial
models of these implements were conducted to acquire data for draft by developing appropriate
instrumentation to validate the developed draft equation. The average absolute variations
between the predicted and measured values of draft were within 5.5 % and 11.6% for all the
implements tested, and thus validated the developed draft prediction equation.
