a machine for harvesting flax. The design of the flax combine was developed in 1947 by the Soviet designers A. S. Maiat, M. I. Shlykov, and A. S. Moiseev. In the USSR the LK-4T and LKV-4T trailer flax combines are used.
The LK-4T combine has a four-section pulling mechanism for pulling out the flax stalks and a cross needle-type conveyor, which delivers them to the gripping conveyor. The latter feeds the stalks to the deseeding chamber where the rotary-comb dresser removes the seedpods and an air current throws the pods onto a conveyor that drops them into a trailer attached to the combine. From the gripping conveyor the deseeded straw is delivered to a spreading sheet from which it falls back onto the field in the form of a strip.
The LKV-4T combine differs from the LK-4T in that it has a removable binding unit for tying the straw into sheaves. The flax combine may also be used as a flax puller, if the deseeding device is turned off. All the working parts of the flax combine are driven by a power take-off from the tractor. The operating width of the flax combine is 1.52 m and its productivity is 0.7 hectares per hour.
