In challenging working conditions that push a tractor to its limits, a dozer can prove to be an effective machine. In order to guarantee great perforᴍᴀɴce in all operating situations and enable production on even the most difficult terrains, the dozer is currently marketed with a variety of configurations and technological advancements. The agricultural tractor is incredibly adaptable and is used well for both significantly more labor- and energy-intensive activity like earthmoving as well as energy-intensive operations like seeding and fᴏᴅᴅer harvesting.
The flexibility of the classic wheeled tractor to adapt to diverse operating conditions by altering traction, tire pressure, or mounting other tire models, and changing the weight of the machine by shifting ballast, can provide exceptional efficiency for any type of problem. The farm tractor is a highly developed piece of equipment with a typical weight/power ratio of roughly 40 kg/hp, which is adequate for tasks as difficult as plowing and subsoiling.
In these circumstances, as well as when using a large leveling blade, the perforᴍᴀɴce limiting factor is not so much the power the engine can produce as it is the adherence, or what is produced by the weight on the drive wheels for calculating the adhesion coefficient as a function of powered wheel slip on the surface of the soil. Weight being equal, it is obvious that a tracked machine will be able to gain greater adherence than a wheeled one and would therefore be able to tow implements that weigh more. In general, the adherence coefficient for wheeled tractors ranges from 0.4 for seedbeds to 0.65 for unpaved roads, while for tracks, these values increase by about 20%, thus from 0.5 to 0.8.
The propulsion components will start gradually slipping if enough traction is required, eventually negating the vehicle’s ability to go ahead. Giving it gas in this situation is not only ineffective but also destructive. Therefore, it is necessary to lessen the force of traction, perhaps by lifting the plow or increasing the weight of adhesion. This can occur in farming when deep break-up plowing is used to plant vines and orchards, or when large amounts of earth are broken up to arrange the land.
Given the benefits mentioned, dozers should have been widely used in agriculture. However, any tracked machine raises significant issues in real-world situations that must be resolved. The first is using public transportation. The process of taking a curve also pushes the machine laterally to line up with the driving track rather than keeping it aligned on a longitudinal axis, causing a dramatic reduction in traction that is actually half. It must also be taken into account that these circumstances become almost equivalent when, for example, a single track is stalled while traveling straight forward due to running over a large boulder.
The use of a dozer can create ᴅᴀɴɢᴇʀᴏᴜs operational conditions that are difficult to foresee and ᴍᴀɴage by drivers used to operating vehicles that are not propelled by tracks. As a result, it is a good idea for this machine with significant tonnage to be driven by expert personnel for operations that are solely agricultural.
