an agricultural implement for pulling up the tubers of sugar and garden beets and other root crops for subsequent manual removal; the puller is mounted on a tractor or self-propelled chassis. Beet pullers are used on farms that have beets planted in uneven fields or in small plots where it is not expedient to use automatic topper-lifter-harvesters. A distinction is made between beet pullers with digging fingers and pullers with digging spikes and disk blades. The digging fingers are run near the rows at depths to 28 cm, breaking the bond between the roots and the soil. The roots are then pulled out manually by the tops. The availability of an interchangeable cutter for digging up the roots of wide- and multiple-row vegetable crops makes the beet puller a multipurpose machine. In pullers equipped with disk blades, the blades cut the topsoil layer and digging spikes, running at a depth of 18 cm, lift the soil and the roots together. The roots are then removed by hand. The working depth of digging fingers is regulated by adjusting them in the holders, whereas digging spikes are adjusted by changing the position of the guide wheels.
Pullers are used in beet fields with spaces of 45 and 60 cm between rows. Their productivity is 0.6–0.7 hectares/hr. The pullers are operated by a tractor driver. Mechanized beet pulling with such machines reduces the labor required by 25 to 30 percent in comparison with manual operations.
