Front end loader with automatic levelling for farm tractors

One of the most commonly used accessories in multiple applications with farm tractors is the front end loader. There is a broad variety of loaders that can offer a range of possibilities and advantages to the operator. Depending on the task to be developed, the functionality that the operator requests from the loader may be different. Nevertheless, in order to avoid significant loss of product during transport, in most applications it is desirable for the loader to be level throughout its movement. In this paper, a new methodology for achieving a high quality levelling is described. This methodology, when compared to the alternative options that can be found in the market, presented favourable features. The proposed methodology could be implemented at affordable cost by using a reduced set of inexpensive components and can be applied to both new and old tractors. (C) 2016 IAgrE.
