The purpose of deep plowing is to modify the soil water retention characteristics over the long term. [1] In one long-term test, lasting 35 years, the mean annual grain yield was 2,800 lbs per acre (3,138 kg per ha) with deep plowing, which was 10% greater than the 2,550 lbs per acre (2,858 kg per ha) yield in unplowed plots.

The tractor's direction is controlled by a lever to the right of the operator for forward, neutral, or reverse operation. Because of this, this tractor is often mistaken for having a hydrostatic drive. In 1965, Kelly G. Cunningham used the Gravely 7.6 tractor to create the Terramite Model 1 compact backhoe, now known as the T1. [4]

If the leaf layer is more than 2 inches thick, remove it by raking or using a lawn mower with a bagging attachment. Add the collected leaves to a compost pile or garden bed. Thin layers of leaves ...
The immense pulling power of steam tractors allowed them to be used for plowing as well. Certain steam tractors were better suited for plowing than others, with the large Minneapolis Threshing Machine Co., J.I. Case, Reeves & Co., and Advance-Rumely engines being prime examples. Some of the largest steam tractors, such as the 150 horsepower ...
Tillage erosion is the soil movement and erosion by tilling a given plot of land. [3] A similar practice is contour bunding where stones are placed around the contours of slopes. Contour plowing has been proven to reduce fertilizer loss, power, time consumption, and wear on machines, as well as to increase crop yields and reduce soil erosion.
Soil compaction can occur naturally by the drying and wetting process called soil consolidation, [17] [9] or when external pressure is applied to the soil. The most relevant human-induced causes of soil compaction in agriculture are the use of heavy machineries, tillage practice itself, inappropriate choice of tillage systems, as well as ...
