Spring Tooth Harrow

The spring tooth harrow has 14″ long, spring-loaded teeth that remove the early emerging weeds in both corn and soybeans. Fernholz travels down the crop rows at about 6 mph prior to crop emergence but much slower after the crop has emerged. The harrow seems much more effective in dry top soils than in moist soils. Because of this characteristic, the spring tooth harrow complements the rotary hoe, which is a bit more effective if the soils are on the wetter side. Given the brief period each Spring during which the harrow may be used, the farmer can expect to need several years to learn to use it effectively.
