| Abstract | The effect of cyc1ic variation in draft o n draft contro1
system was studied. Speed a nd depth of ploughing we r e varied to
find their effect on cyclic variation . The experiments were do ne
by using mouldboard plough at field moisture content of 24% d.b.
The settings of the draft control system were not disturbed. The
settings were as per t he recommendations of the manufacturer . For
comparison, the test runs were done in two modes of setting, i .e
position a nd draft control .
The cyclic nature in the draft was observed. The difference
in peak a nd trough values were 5+ 2 kN. The fracture length
remained almost same at all the speeds a nd depths at about
1±0.2m. The total frequency range was di vided into two groups.
Lower frequency range corresponds to the actual soil failure
frequency whereas the higher frequency corresponds to frequency
of the b1ocks of soi1 fai1ing over the mou1dboard surface. The
response of the draft contro1 system was effected by the 1ower
frequencies of the draft. The performance of t he draft control
system was better in l ow speed third gear than l ow speed, first
or second gear . |
