Abstract: An extractor for removing agricultural tubing from soil of a field and related methods are provided. The extractor includes a frame and a pivot frame disposed on the frame. The pivot frame can have a pivot axis around which at least a portion of the pivot frame is pivotal. The extractor can include a first roller secured to the frame and a second roller secured to the pivot frame that is moveable by the pivot frame with the first roller being positioned closer to the soil than the second roller so that a tubing to be extracted is threadable under the first roller and over the second roller.

Abstract: The invention relates generally to harvesters and, more particularly, to a combine for harvesting row crops, which has been modified, to collect and measure grain continuously from a plurality of strip test plots.

Abstract: The invention relates generally to harvesters and, more particularly, to a combine for harvesting rows crops, which has been modified, to collect and measure grain from two separate small strip test plots. The present invention is a dual plot combine with two separate and distinct internal sections of the combine. The combine's intake has two floatably mounted feeder house. This invention harvests two lots simultaneously while maintaining the integrity of each plots' harvest data. The dual plot combine has two separate unconventional grain paths for collecting and measuring the cleaned grain drums The divided clean grain bin and weigh bucket are positioned at a low position, inside the vertical confines of the combine, on a single side of the combine. The altered grain paths allow the data collection on the clean grain from each plot to be completed quickly. This in turn allows the combine to progress to the next set of two plots quickly.

Abstract: A harvester with unconventional grain flow for collecting and measuring grain grown on strip test plots. A conventional harvester having a weigh bucket for measuring grain located at a high position is modified by reversing the grain flow of a lateral conveyor and locating the weigh bucket at a low position inside the vertical confines of the harvester. The modified grain path upstream of the weigh bucket reduces the time required to move harvested grain to the weigh bucket and thus the waiting time required between harvesting of successive strip plot tests.
