heres a example ,pretty simplisticly.say i use his rig with a 12" plow,right beside it is a tractor burning twice the fuel with 2-12"lets compare, 1-fuel effeciency,tractor one burns one gal per hour,tractor 2 ,2 gals.tractor 1 plowing a feild 100' wide will make 100 passes,tractor 2 -50.at the exact same speed which tractor is more effecient?two of course its ran half the time did twice the work on the same amount of fuel as 1 2- tractor wear,again all things being equal tractor 2 is the winner hands down simply because its ran half as long under a load. 3- plow wear- heres where it really gets interesting,tractor 2s two bottom plow has did the same amount of work as ones with (A) half the time in the ground as number 1s this means wear on share due to time at a certain wear factor is wear x time = 1/2,in the same exact ground the one bottom plow will WEAR twice as fast as two per bottom.this means simply that if hes plowing 10 acres between share changes we should plow twenty in the same ground with the two bottom.(b) now not only was the two bottom plow in the ground half as long it also traveled on each share half the distance.again same share and ground, since wear was cut by half due to time,it was also cut by half due to distance .again same wear factor, our two bottom plow should last not twice as long,but 2 times due to time X 2 times due to distance =4 times the acres which in this case would =40 acres,so plow 1 for every 10 acres would have the same amount of wear as plow 2 would have if we plowed 40 acres! simply by adding ONE bottom! nothing else.when you start figuring it up this way he may not be getting bad service at all.lets see, if we know hes getting ten acres to the share lets extend it out to our plows and check. 2- bottoms 40 acres (2x2x10) 3- bottoms 90 acres (3x3x10) 4- bottoms 160 acres(4x4x10) 5- bottoms 250 acres(5x5x10) in my experience thats probably not bad service especially if his ground is pretty abrasive.

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
