New Zealand root pruner evaluated for U.S. use

Many nurserymen prune the roots of seedlings in the beds to modify root and top growth, loosen soil, and facilitate lifting. Some nurserymen prune the seedlings horizontally only, while others prune both hortizontally and vertically. If roots are to be pruned both hortizontally and vertically, two passes are made over the beds, each with a separate pruning implement. A machine that prunes seedling roots horizontally and vertically on one pass is being used in New Zealand. During the spring of 1972, the Missoula Equipment Development Center evaluated a unit that functionally duplicates the New Zealand root pruner to see if it would be effective in U.S. nurseries.
