Newer tractors are RACINE, Wis. - For several decades the entire farm tractor-industry has been moving in a well defined product pattern. What has evolved from the - tractors are - at ig new jrsepower weight ratios. Some farmers are using the extra horsepower to pull larger im plements, but research at the J I Case Company suggests they ought to look at the production gains they can -realize" by putting that horsepower to work in a Rapid Farming System. © L S£S Bodies Precision engineered roll "formed 52" high steel sides provide greater capacity at less cost.

Since the early 1960’s average ratio of ballasted tractor weight to PTO/hp has decreased from 160 pounds per PTO/hp to an average of 115 pounds.

If a fanner purchases a tractor with 25 per cent more horsepower than the one he is using, he can cover 20 per cent more ground using the ground working tool he already owns. For example a 100 hp tractor pulling a 20 foot disk harrow at 4 miles-per-hour effectively cover eight acres per hour. A 125 horsepower tractor pulling the same 20 foot disk harrow at 5 mph will effectively cover 10 acres per hour. The alternative to going faster using the same im plement is to use the extra horsepower to pull a new, wider implement. But it is a mistake to assume that, in all cases, 25 per cent more horsepower will necessarily allow the fanner to increase I The gift of the season for every good reason special ■ saw saver Kit Included with purchase of Echo 315,302, ■ 351VL or 452VL at regular price Kit consists of carrying S case, extra chain, Sure sharp chain file, wedge and B filing gage SAW SAVER KIT Bonus Value Worth Approx. *40.00 ABC GROFF.

Here’s why: Drawbar horsepower is a function of speed as well as drawbar pounds pull. Therefore, you can transmit more drawbar horsepower at higher speeds. The Drawbar Performance Chart, Figure No. 2, shows that the maximum drawbar horsepower is always achieved at the higher rate of travel speed (usually in the 5 mph to 6 mph range) and never at the highest drawbar pounds pull. Another plus factor for using the Rapid Farming System is that reliability of tractor can be increased as i., operator farm faster.
