A COMBINATION OF A TRACTOR AND A BALER FOR BALING HARVESTED CROP, AND METHOD OF BALING HARVESTED CROP THEREOF

The present invention relates to a combination of a tractor and a baler for baling harvested crop, said combination comprising: - at least one bale sensor (274) to detect whether a bale (B) has reached a predetermined size in a baling chamber of the baler (10), in particular said at least one bale sensor (274) being located in proximity to said baling chamber; - a baler controller (210), in particular located in the tractor (100), configured for receiving information from said at least one bale sensor (274) pertaining to whether the bale (B) reached the predetermined size and for initiating bale (B) wrapping; - a tractor stop command device (212) located in the tractor (100) for activation by an operator after the predetermined bale (B) size has been reached; - at least one speed sensor of the tractor (100) to detect the speed of the tractor (100); - a tractor controller (250) connected to said stop command device (212) and to a tractor drive system, said tractor controller (250) comprising a processor to generate a value regarding a pre-set speed from a speed information detected by said at least one speed sensor; - a communication link between the baler controller (210) and the tractor controller (250), wherein the tractor controller (250) informs the baler controller (210) to initiate bale wrapping at said generated value, said combination of tractor (100) and baler (10) being characterized in that said tractor (100) comprises a dual clutch transmission (701) comprising: - an engine input shaft (702) configured to be coupled to the output of an engine of said tractor (100), - a intermediate geared shaft (719) configured to be coupled to said drive system, - a forward clutch (705) and a rearward clutch (706), each configured to be coupled to the engine input shaft (702); - a first intermediate shaft (711) and a second intermediate shaft (712) comprising a plurality of gears (714, 715), said first and second intermediate shafts (711, 712) being configured to be coupled, via respective first clutch (707) and second clutch (708), to said forward clutch (705) and to said rearward clutch (706) and being configured to be coupled to said intermediate geared shaft (719) defining with one of said gears (714, 715) a predetermined speed ratio between said engine input shaft (702) and said intermediate geared shaft (719), each of said gears (714, 715) defining a different predetermined speed ratio among them between said engine input shaft (702) and said intermediat
