2C--Mpf F (fßhviffrf 1 «mnni( - <n<»«>n< • 34—Lancaster Farming, Saturday, August 3, 1974 A test frame at the National Tillage Machinery Laboratory, Athens, Alabama, holds a pneumatic track designed for farm equipment. The track reportedly performed better than a regular pneumatic tire, and almost as well as a steel track in use tests. The track has a ground contact area of 6.3 inches by 55 inches, and stands 4.5 feet high. Pneumatic Track Outperforms Tire track in two tests and out performed the steel track and pneumatic tire in soil pressure tests. Taylor said the pneumatic track has potential for high speed use in the field and on hard-surfaced roads Droved past, steel tracks proved superior to pneumatic tires in traction; their use, however, was restricted because of slow speed, rough ride, high initial and maintenance costs, and their prohibition on hard-surface roads. An experimental pneumatic track for farm equipment performs better than a pneumatic tire and almost as well as a steel track, according to a recent USDA Study. The pneumatic track, which is of Italian origin, was tested by agricultural engineers James H. Taylor and Eddie C. Burt of the National Tillage Machinery Laboratory at Auburn, Ala. It performed on a nearly equal basis with the steel *o*'. MR. DAIRYMAN: The dai|7 farmer in California, due to his breeding and management and his feeding program, has come up with a very high productive herd over the last 8 years. These rolling herd averages are 54 pounds and up which is nothing un common, they were forced to look into better milking systems that would do the job with a minimum of udder irritations such as; 1— Low Vacuum of lOVz” to llVz” 2 Not flooding at the teat end 3 No back flushing of the teat canal 4 Proper pulsations per minute 5 Milking all four quarters out together s—Alternating twin-pulsation for front & rear quarters SHENK'S FARM SERVICE RDS, Lebanon, Pa.

Whether you are milking 15 cows or 1500 it will pay you to in> estigate what Bou-Matic can do for you and your herd. A Dari-Kool Bou-Matic Milking System along with good herd management has proved a winning combination for thousands of dairymen. Ask any Dari-Kool Bou-Matic user. Both types of tricks outperformed the pneumatics tire in tests of dynamic traction ratio (pull weight) and tractive ef ficiency on wet and dry Norfolk Sandy Loam and Decatur Clay Loam soils. The pneumatic track,, however, outperformed both the steel track and the pneumatic tire in soil pressure tests. The total soil contact area was identical for the pneumatic tire and the pneumatic track. The long, narrow ground contact area of the track offers two distinct advantages toward solving two problems that increasingly concern many farmers. The track disturbs a smaller area of soil on each pass through the field, and the soil pressures and bulk densities are lower, Taylor said. Pressure measurements were made at BINKLEY & HURST BROS.

The pneumatic track concept has the potential for combining many of the desireable features of pneumatic tires, resulting in a traction device superior to anything now available.” Modern Question Old gentleman • “What’s wrong with the new generation’” Business man “They’re being brought up on the wrong side of the tax ” Same Track?
