Show PULLING POWER OF HORSES experiments in california give interesting results concrete offers least resistance dy E B HOUSE colorado agricultural college fort coulas A very interesting experiment has recently been concluded in california to just how much a horse pulls when he draws a ton A good draught team was used for ahls purpose the weighed 1 COO pounds each they were hitched to ay T 1 x y y v v f r V W jam t 4 J s 1 k IT t on state highway from colorado springs to canon city cal an ordinary farm wagon and pulled a load of pounds over different kinds of roads the wagon was a standard farm wagon with steel axles of equal length wheels sa and 40 inches in diameter and tour inch tires A recording dynamometer known as the iowa type was used to register the force of the team this makes a record of the resistance si on a strip of paper under a recording pencil and after the test the total pull of the team can be read ofle in pounds the record of the test Is as follows on a concrete road in excellent condition the total pull on hie load was 83 pounds or 27 6 pounds per ton on a concrete road with three eighth surface of lc oil and screenings road in excellent condition the total pull was 6 pounds or pounds per ton on the ordinary macadam road in excellent condition the total pull was pounds or 64 3 pounds per ton for a graveled road compact and in good condition the total pull was pounds or 75 pounds per ton an earth road firm with one and ono bialt inches of fine loose dust the total pull was pounds or 92 pounds per ton an earth road with mud 4 to C inches deep but soil firm underneath the total pull was pounds or pounds per ton on graveled road before the gravel ha 1 been compacted but when it w as in ordinary loose condition after it had been placed upon the road the total pull was pounds or pounds per ton the above shows very well what great advantages good roads have on the hauling properties of a team CHECK HEAVY WATER FLOW catch drain should be constructed on sade of hills to cany flow to ends of cut on the side bills where the flow of water Is heavy it should be kept from reaching the road by constructing a x atch drain a few feet back and above the edge of the cut tills will carry the water along to the ends of the cut and thus keep it oft alie road it the cut Is a long one the water in the catch drain can be disposed 0 at intervals bv dropping it through a pipe or gutter into the cu lverts |
