A mechanical row crop weeder was developed to overcome the tedious manual weeding operation experienced in a row crop farming system and its performance evaluated. The machine is made up of a frame, handle, hoeing disk, pneumatic wheel, belt/pulley and power unit. Three different weeding tool types (U-blade, L-blade and Hoe-blade) were developed and used at three different walking speeds of 0.2, 0.4, and 0.6 m/s in three replications. The experimental plots were 27 which measured 800cm by 26cm each. Parameters such as weeding efficiency, weeding index, Field efficiency, effective field capacity and theoretical field capacity were measured using standard known formulae. This weeding machine has a swath-width of cut of 26cm which corresponds to an average furrow width of farm cropping system. Results from field performance showed that both theoretical and effective field capacities increased with increase in the walking speed of the operator while field efficiency decrease with increase in the walking speed. The mean field efficiencies obtained were 93.58 %, 91.91 % and 85.64 % at the walking speeds of 0.2 m/s, 0.4 m/s and 0.6 m/s respectively. ANOVA revealed that the working speed and tool type have significant effect on the weeding index and weeding efficiency of the machine at p<0.05. The results showed that weeding index decreased with increasing walking speeds with all the tool types investigated, the walking speed of 0.2 m/s had the highest weeding index of 0.937 with the L-blade tool type. The least weeding index of 0.580 was obtained at the walking speed of 0.6 m/s with the hoe-blade tool type. The highest weeding efficiency of 93.7 % was obtained for 0.2 m/s walking speed and L-blade tool type. This device will contribute greatly to weeding status of row crop farms for small scale farmers
