A computer-implemented method for managing crop harvesting activities is implemented by a harvest advisor computing device in communication with a memory. The method includes receiving an initial date of a crop within a field, receiving an initial moisture value associated with the crop and the initial date, and receiving a target harvest moisture value associated with the crop. The method also includes receiving field condition data associated with the field. The method further includes computing, by the harvest advisor, a target harvest date for the crop based at least in part on the initial date, the initial moisture value, the field condition data, and the target harvest moisture value, and displaying the target harvest date for the crop to the grower for harvest planning. The target harvest date indicates a date at which the crop will have a present moisture value approximately equal to the target harvest moisture value.

This row unit utilizes an improved multi-zone, multi-functional stalk roll, which contains a novel revolving entry window to improve entry and increase engagement of the fluted portion of the stalk roll flutes with the corn stalk. The stalk rolls described are multi-sectional and contain multi-length variable flutes. The number of flutes described for each zone may vary as well as whether the flutes are meshing or non-meshing and angled or non-angled. The stalk rolls described allow a constant speed drive shaft to create lower and / or higher effective circumferential contact speeds within each zone of the stalk roll. The invention provides that the rotating transport vanes located on the helical nose cone at the entry area to the stalk roll flutes lock the corn stalk into a revolving entry window. This novel row unit contains a multi-zone, multi-functional stripper plate that ensures minimal ear wedging and maximum discharge of material other than ears. This row unit utilizes a novel gathering / conveying chain(s), which reduces the number of and increases the angle and size of the paddles. This row unit design optimizes operation between the components imparting force to the corn plant and ears. The invention has a smooth uninterrupted improved flow of corn stalk material through the ear separation chamber and is the first row unit designed to be environmentally friendly by ensuring that the majority of the corn plant remains connected to its original root system which prevents it from rapidly decomposing, blowing or washing away. The row unit cover is spatially designed for improved flow in down, damp and tough harvesting conditions.

A sieve assembly for separating grain from chaff inside of a combine. The sieve assembly comprises a plurality of longitudinal sieve planks that pivot on their longitudinal axis. A hanging weighted member combined with the sieve planks regulates the angle of the sieve planks relative to the combine. As the combine becomes laterally inclined on a hillside, the weighted member changes its angular position relative to the combine. In doing so, the weighted member causes the sieve planks to pivot on their longitudinal axis so that the sieve planks remain level relative to the horizon. Dividers extend between each sieve plank.

A drive arrangement for the drive of an agricultural implement is provided that includes a drive engine that can be brought into a drive connection over a separable power take-off shaft clutch with a power take-off shaft output. A drive line of the operating implement is connected with the power take-off shaft output, with an overload clutch, and a control arrangement.
