The combination of the hillside plow and the Beatty grader resulted in the highest rate of production under the conditions of this test. The other equipment may not have been as easy to handle as the hillside plow. In addition, the operators have more experience and are more comfortable using the hillside plow and Beatty grader.
The production rate obtained with the MTDC combination plow and grader was about 10% less than that obtained with the hillside plow and Beatty grader combination. This is a relatively small difference. However, the equipment operators agreed that the MTDC grader was much more difficult to control than a hillside plow. Thus, the hillside plow was preferred to the MTDC grader in the test config-uration.
The Trail Ace and Trail Scoop combination resulted in the lowest production rate, or about half the production rate of the hillside plow and Beatty grader combination. This result may be misleading for several reasons. First, this test was conducted on a relatively short portion of trail. Second, this portion of the test was conducted by different operators (manufacturers) using a different stock-handling technique. Although this is the lightest of the trail equipment tested, the handle design and angle may be reducing the efficiency of this equipment by requiring more ‘handling’ than ‘guiding’ of the implement. This technique requires the crew to make more passes over the trail than the hillside plow and Beatty grader combination, or the MTDC grader.
The Fremont grader did not perform effectively in the soil type and vegetation type in this area of Idaho.
