 Howdy, I was looking through my manuals and came across one for the International 240-checkrow, 241-drill, and 242-power hill drop and this might be of help to you----- - I scanned the back cover of the manual and it shows the 240 check row. I have made a note on the picture for where the check row wire ran. One of the main reasons for "checking" corn was so the farmer could cultivate the corn the length of the field and then crosswise. Keep in mind this was before the days of the weed killers we have today so this was the best way to keep the weeds down. For drilling corn, the manual says " When drilling with the Check-Row Planter, lock both check forks to hold the valves open by hooking the forks under the clip on the rear flanged roller stud. When desiring to check, release both check forks. (See illust.6)" "For drill spacings with Check-Row and Power Hill Drop Planters, there are three sprockets on the main axle, which, with the variable drop pinions on the seed shaft, provide nine different spacings with any seed plate." "Drill planters (No. 241) has a double sprocket on the seed shaft and three drive sprockets on the axle, which, in connection with the variable drop pinions on the seed shaft, provide fifteen different spacings with any seed plate. (See Table of Drilling Distances.)" And to tell if your machine can be used for Power Hill Drop planting----- ---- "The Power Hill Drop planter is furnished with all planters having the rotary stop clutch." I'm not sure where the clutch is located but the manual says the clutch is somewheres on the check row shaft. Sorry for being so long winded but I hope this info helps you out. My two bits worth, Old Iron
