A disc harrow at Bartley Ranch loop trail


This picture shows a disc harrow, which was once used on the Quilici Ranch near Dayton and is now on display at the Ranch Loop Trail at Bartley Ranch in Reno, Nevada. A walking tour along this trail takes visitors to various farm equipment including a spring tooth harrow and this disc harrow, for which an interpretive panel explains that it is traditionally used after a field had been plowed. It prepares a field for new crop growth by cutting remaining stalks and roots from the previous harvest into the soil and it helps loosening the soil and smoothing the surface. The panel provides the following details:

The [disc] harrow is pulled across the field causing the series of circular concave discs (which are set at opposing angles) to rotate, thereby cutting the remains of the harvest into the soil, replenishing the topsoil as it decays into humus. Depending on the previous crop, this may take several passes.

Harrows are a type of agricultural machinery that has been used by now the Middle Ages disc harrow are upset subsequently than it comes to cultivating the soil previously crops are planted. The main advantage is that they can chop taking place soil that has been recently plowed and so eliminate clumps or clearly loosen the soil if it has been packed. In the adding taking place together, they were horse-drawn, but today they are usually towed after the tractor.If you are looking for disc harrows or supplementary subsidiary or used agricultural machinery for sale, mean the Internet.http://www.haniffarm.com
