Description

Technical Field

[0001] The utility model relates to the technical field of tractor transmission, in particular to a tractor side control integrated device. Background Art

[0002] On traditional agricultural tractors, the transmission control mechanism typically consists of a main and auxiliary speed lever connected directly to a side control mechanism on the transmission housing via an elastic cylindrical pin. The driver uses the lever to directly operate the drive shaft to select and shift gears. However, this shift mechanism typically extends from the floor, resulting in a long lever that increases the travel required to engage or disengage gears. This intrudes on the driver's legroom during shifting, reducing comfort and hindering ergonomics. Furthermore, the layout must consider the side trim and other control locations, resulting in limited space and inconvenience for the driver when getting on and off the vehicle. Furthermore, touching the shift lever can cause gear shifting or disengagement.
