Lethbridge Herald, The (Newspaper) - October 1, 1974, Lethbridge, Alberta Now Paul's got it all. Paul Maley has good reasons for using a Caterpillar D4D track-type tractor to (arm 1400 acres in southern Alberta. Some of Paul's reasons for using a Caterpillar unit instead of the conventional wheel tractor are based on the following facts ECONOMY During hours of operation the total repair costs were Fuel consumption is up to only 4 gallons per hour pulling a 24-foot cultivator or a 28-foot hoe .drill at 5 miles per hour, Let's compare tire and under- carriage costs per hour in heavy loam soil conditions; TRACK-TYPE TRACTOR Hours Turn pins and bushings 150 200 Rebuild rails install new pins and bushings Turn pins and 150- 200 Replace under- TOTAL 33 40 FOUR-WHEEL DRIVE TRACTOR 8- 18.4x38 tires Life expectancy, hours Cost per hour 23 PERFORMANCE One major performance inefficiency in wheel tractors is excessive slipping of the drive wheels, and if wheel slip is noticeable there's at least 10% slip occurmg. Tests conducted by the University of Manitoba and the Agricultural Department of the Province of Manitoba have shown that tire slippage over 16% is unacceptable due to excessive tire wear, which results in high costs. Crawler tractors seldom exceeded 5% and then only in the first gear range. Wheel slip lowers the drawbar horsepower output by reducing speed To reduce slippage, extra counter- weight, etc, dual-tire arrangements and tire ballast are often added, While this increases usable pull, it creates problems like machine overloading, increased fuel consumption, additional equipment costs and increased soil compaction, COMPACTION Each time the ground is worked by a conventional wheel tractor there is approximately 5 times as much ground pressure exerted as by a crawler, resulting in increased soil compaction, poorer crop yields, greater horse- power requirements to prepare the seedbed and less profit to you, the farmer. A Caterpillar Special Application track-type tractor can operate at a lower cost per acre and cause less soil damage than the conventional HP wheel-type models. RESALE VALUE From comparative tractor auction records, Caterpillar tractors have traditionally had higher resale values because the working life of a track-type tractor has been estimated to be 33% to 100% longer than that of a wheel tractor doing lighter work COMFORT Since track-type tractors lay their own road, they are actually smoother riding than wheel tractors. To add to his CATERPILLAR SA Speeds low-top, approx Clearance 06 comfort, Paul equipped his D4D tractor with a cab, Bostrum Viking T-Bar seat, air purifier, radio and earphones DEALER SUPPORT R Angus is your Caterpillar dealer in Alberta and the central Northwest Territories.
