Combines means: A combination is like an acorn, but larger. They can easily be tripped and need to be harvested. A new combine harvester can make them a range of colors, but they are mainly yellow or brown. Although combine harvesters can be enjoyed by many animals, they are usually only suitable for small-sized ones. Combinations are made from trees and acorns, which can be eaten by squirrels or rabbits. They are a combination of the two. (in Community Dictionary, added by Umlaut)
