Modifications of a Lowther Tree Planters for Better Quality Planting and Survival
The addition of a set of scalper plows to a standard model Lowther tree planter has increased the survival and growth of planted pine seedlings on the Kisatchie National Forest in central Louisiana. These scalpers have been in use for the past three planting seasons. In order to permit the plow beam to be raised, an arch was built into the frame of the planter. Figure 1 shows the right-hand scalper plow and the arch in the side of the frame. Another scalper plow is located on the left-hand side of the rolling coulter. The initial cost of the scalper plows was $75. Replacement points cost about $34 per set. In general, a set of plows will last through one planting season, but this varies with soil type and amount of use. The cost of the plows, however, is a minor item when prorated on a basis of per thousand trees planted.
