A method including adjusting a changeable component of a seed planting machine when switching from a first variety of seed to a second variety of seed during planting, wherein the adjusting is based on a location of the planting machine.

A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short drop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture, move and accelerate the seed. By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.

A hydraulic motor assembly includes a flow controller, a displacement controller and a hydraulic motor. The flow controller controls the flow of hydraulic fluid through the hydraulic motor and the displacement controller controls motor displacement. The hydraulic motor converts the pressure and flow into angular displacement of a drive shaft. An electrical generator is connected to the motor drive shaft and provides electrical power to accommodate a varying electrical load. As the electrical load varies, the flow controller and displacement controller vary the flow and displacement of the hydraulic motor to vary the torque applied to the generator by the drive shaft so that the drive shaft rotates at a desired speed.

A seeding machine includes a seed metering system and a seed delivery system in communication with the seed metering system. The seed delivery system includes a housing having a first opening for receiving seed from the seed metering system and a second opening through which seed is discharged. The seed delivery system also includes a conveyor forming a loop with a fixed length and positioned within the housing. The conveyor is disposed around a first drive pulley and a second idler pulley. The conveyor is deformable in order to retain seed at any point along the fixed length.

A seed delivery system for a seeding machine having a seed meter comprises a housing that defines an upper seed loading area and a lower seed discharge area. A drive pulley is mounted to rotate with respect to the housing. A belt is supported for rotation by the drive pulley within the housing. A loading wheel is mounted to rotate with respect to the housing to transfer seeds from the seed meter into the belt at the seed loading area. The belt conveys the seeds through the housing as the belt travels from the seed loading area to the seed discharge area.

A combination is made up of a tractor and a seeder suitable for direct drilling mounted on a three-point hitch of the tractor. The seeder has a crossbeam that is connected to the three-point hitch and on which a plurality of sowing units are arranged laterally in succession. The sowing units, each equipped with at least one furrow opener, are respectively prestressed downward in relation to the crossbeam by an actuator, and the three-point hitch can be self-locked in relation to a chassis of the tractor. During the sowing operation, the pressing forces for the furrow openers are therefore introduced via the sowing units, the actuator, the crossbeam and the three-point hitch into the chassis of the tractor.
