- Advant'ageS‘of Surplus Tractor Power Be Sure Your Machine Can Climb Steepest Grade and Go Through Heaviest Soil BY F. H. SWEET ] HE more tractor experi- ence 3 man has the more certain he - is that he needs surplus power to take him over hard and unexpected places. The man who owns a tractor that devel- ops 15 horsépower at drive wheel rims finds himself in a disagreeable situa- tion when, due to degree of grade or character of soil encountered, his ma- chine stalls. ‘He can not very well back up, if plowing, to get a new start. Therefore, the only: alternative is to lift the plows and leave a blemish in the plowed fields. What he wants, and what he is bound to have some - day, is a tractor that will furnish, at least for a short time, a considerable surplus of power to take him up steep grades, through hard spots m the soil, or. both at once. A horse has the ability to produce surplus .power in large amounts for _ short pemods For a moment, while . tugging in the collar, he may pro- duce five times the amount of energy 2hat is expected of him at steady work. Who has not seen the powerful truck horse -straining at his load te get it up the grade to the unloading ~ platform? While doing this the horse is exerting many times the strength required of him orn the main portion of the journey over level streets. The driver who gets stuck on the road or in the street fails for the entire trip, due to one bad place in the road; the same is true of the tractor that has not-enough excess power, which may be called upon when necessary, to carry over the steep grades or through - tough hard spots in the soil. TRYING TO DEVELOP A BETTER TRACTOR: It is the ambition of progressive _tractor builders of today to produce machines that, in a degree at least, ' “compare with the versatility of the horse.. When the farmer understands that he ecan purchase a tractor that for all the working period will develop, say; 15 horSepower except for 10 min- utes when he must have 25 horsepow= . er—that is the tractor he will buy and recommend’ to others when he finds he can get it. There is a wxde Tange of soil con— ditions and soil contents. It may take 2,240 pounds pull on the level to op- erate a 14-inch plow eight inches deep- m gumbo soil, while the same plow ‘may be pulled through sand at the same depth on level ground with a -pull of 336 pounds. Assuming that { @ the farmer ran from sand to gumbo in the same field, he could not hope to get through hls gumbo with power sufficient only for the sand or silt loam. What he wants and will have some day is the latent power. to call on,when he strikes the streak of gum- bo, so that he can go right through it without let or hindrance. It has been fairly accurately esti- mated that it requires 42 horsepower - to pull three 14-inch plows eight inches “deep through dry gumbo soil, while to puill the same outfit the same’depth through new land or virgin soil con= sumes 10 horsepower. In medium ‘heavy clay the amount required is 17 horsepower; light clay, 13 horsepower; - silt loam, eight horsepower, and sand about seven horsepower. It is plain, thereffire, that the range of power. - meeded is wide, indeed, and that the . successful tractor must be built to meet this condition, modified to meet New soil is, . engineering regtrictions. of course, not plowed eight inches frorxzz wlhezlat and gthe}f gralfnsdmak;ha p/ The Graln-Savmg particularly ' good sheep fee e o S Y “weed seeds have about the same com- Is Commg to You Stacker Deliversit ElllsKeyatoneAxriculturalWorks.

In the case of gumbo this is 20 pounds; hence, your problem is 8x14x20, or 2,240 pounds, and for the three-plow gang the problem is 8x14x20x3,. or 6,720 pounds pull. - In sand the prob- lem is stated thus: 8x14x3x3, or 1,008. Thus we have 6,720 pounds pull necessary for passing through gumbo and 1,008 pounds pull for negotiating sand. “The entire range between these figures may be encountered in the same field of operatlons, although this is’ not. probable. The man who hves in a rolling country will also find himself con- fronted with a real problem in getting his tractor to pull a load while going up hill. A 5 per cent grade, which is equivalent to 8 degrees, will require 300 pounds additional energy to move both tractor and plow up hill, assum- ing that the tractor weighs 5,000 pounds and the. plows weigh 1,000 pounds. 'If, then, the user encounters a heavy streak of clay, or even gumbo, while - going up hill, the need of re- serve power is all the more obvious. A 10 per cent grade, or 5% degrees, means that the tractor must generate 600 additional pounds pull at the drive wheel rim in order to move forward; and on a 30 per cent grade, or 16% degrees, the additional load imposed is 1,800 pounds, or a difference "of The Leader does not knowingly accept advertising from more than 12 horsepower from that dishonest people.
