A plow frame with loose bolts and worn wheel boxings cannot be expected to do good work. Your wife does not let her sewing machine get all up.

Sanborn reports a difference of only per cent in favor of an old point res;iarpeued over a dull point in the same plow, but an advantage of 36 per cent in favor of a new point over the old point resharpened. At all events farmers should not waste time on dull shares. Great care should be taken when sharpening shares to return them with the same "set". The same amount of suction both downwards and to- wards t^e land. Shares in the condition of those shown in Figure 13 are far too common. Scouring Qualities of the Plow and Soil. There are many different shaped moidboards for different soils. Right here let me say that unless a. Figure 13. moldboard plow will not scour a disc plow should not be considered. There are districts where the heavy gumbo soil demands disc plows. "Prevention is better than cure" â when you put your plows away next fall smear t^em well with thick oil and they will scour easier when started off the following Spring. Cafe must be taken to see that shares are not warped. If they are, a good joint is not made between the share and the mold board, thus causing trouble.
