Large cutaway or bog harrows of the disk t\'pe were used to prepare land for 

 seeding to grass and clover mixtures after boulders, trees, stumps, etc., w>ire 

 cleared with the bulldozer. In some cases such harrows were us;d after the land 

 had been plowed, but in most instances the bog harrow was used instead of the 

 plow to break up the new ground. A disk harrow was used to pulverize the soil 

 and prepare a seedbed for pasture mi.xtures. Harrows were used instead of 

 plows on land where large boulders and stumps were not removed.
