A combined chisel-ridger implement for economizing power under heavy clay soils

Abstract EN

An experiment was carried out to study the performance of a primary and a secondary tillage implements combined into one machine to economize labour, power, energy and time.

The combined implement was evaluated in the field and compared with individual tillage implements, a chisel and a ridger for unit draft, power requirement, slippage, fuel consumption and time.

The results obtained showed highly significant differences at 1% level between the different implements for the unit draft, required drawbar power, total time and fuel consumption, but the differences were not significant with respect to slippage and fuel consumption.

When comparing the work of the combined implement with the cumulative work of the individual tillage implements, ridger and chisel together, the unit draft was reduced by 26 %, the drawbar power required and the total time were reduced by 49 % and 47 % respectively.

The simple and multiple correlation analysis showed high correlation between the different measured parameters (r = 0.

87–0.

92).
