Site Preparation

Land-leveling scrapers are very efficient and cost effective for moving soil from one location to another. Rubber-tired tractors with shift-on-the go transmissions are used to pull these units. They can be used as single or tandem scrapers. Several styles are available, and single units range in capacity from 5 to 18 cubic yards. Required tractor horsepower varies from 100 to 500. Land-leveling scrapers are widely used for leveling farmland, construction sites, and road projects. They are generally not used for long-haul applications.

Site preparation is critical for successful revegetation projects. Preparation includes tilling to remove compacted layers, improving soil tilth, destroying weeds, and providing a firm, friable seedbed with safe sites for seeded species. Tillage implements are classified as primary and secondary. Primary tillage refers to initial soil disturbance while secondary tillage is the final seedbed preparation prior to planting. Rangeland is often littered with shrub debris so a portion of this chapter is dedicated to implements designed to traverse debris-littered land.
