6 (254)THE RIGHT WAY TO DISK SOD.An Iowa subscriber, Otto Tielebein, submits the following brief communication which we believe will interest those who will be called upon to disk freshly-plowed sod this sprin;I have as yet. never seen any imple-tnent factory give full instructions as to how to use a disk pulverizer in sod ground. I find the right way is to start a new field at the dead furrow or where '• U finished plowing and then work out and let the right-hand half do the i ew cutting and the left half do the second cutting. In this way what sod stands on end will be laid over fiat like a plow. Disking by tfiis method does five or six times as much good as a haphazard way. I have seen some tanners disk their sod five times and then there would he a^s much sod turned green side up as down.“VA 7 Vbelieve that practical men will appreciate the fact at once that by this plan you avoid turning up the green sod. The right hand half of the disk will as stated by this subscriber, act like a plow by tending to remove the upper edge of the furrow slice and place it in the depression between the furrows, thereby the more completely covering the grass.This brings up another phase of tne subject that might be treated in this connection. We refer to the increased efficiency of double disking as compared with the plan of single disking a field twice. This applies not only to newly-plowed sod ground, but to the preparation of any kind of plowed land for a crop. Time and again we have, observed men make the mistake of ridging their land to such an extent by the single-disking process that it was impossible to bring it back into condition by even an endless amount of harrowing.
