APPENDIX II
MACHINERY INSTITUTE REFERENCE COMBINE CAPACITY RESULTS
FIGURE 22 shows capacity differences in wheat crops for the three years. In 1987,
the Katepwa wheat crops had below average straw yield, and average grain yield. They
also had average grain moisture and slightly below average straw moisture content.
Results show that the reference combine is important in determining the effect
of crop variables and in comparing capacity results of combines evaluated in different
years.
TABLE 7 and FIGURES 21 and 22 present the capacity results for the PAMI
reference combines in barley and wheat crops harvested from 1984 to 1987.
FIGURE 21 shows capacity differences in barley crops for 1984, 1986 and 1987.
The 1987 Argyle barley crop shown in TABLE 7 had average grain and straw yield and
average straw and grain moisture.
