Two types of tractor-PTO-powered grassland renovators have been developed in order to renovate grassland in a simple and economic manner and without interrupting grass production. They are based on a rotary cultivator in their concept. One is for grass seed pellets and the other is for seeds. The machine for seed pellets performs tilling (ditching narrow furrows), sowing with pellets in the furrows and pressing by press wheels in one trip. The tilling device is a combination of straight blades and L-shaped blades. The machine for seed pellets with the 2.2m working width performed renovation work with good accuracy in its test. The machine for seeds carries out tilling, fertilizing, seeding soil covering and packing in one trip. Prototype No.2 has an 8-row tilling mechanisms, fertilizing, seedling, and pressing devices, and has the working width of 2.16m. Two straight blades and four L-shaped blades are attached to a flange of the rotary shaft. Grassland renovation with this machine proved to be effective in improving grassland vegetation and increasing pasture yield. The tractor power required for the prototype No.2 was estimated at 44 kW or more
