A large foldable four-ridge-eight-row peanut planter comprises a mounting frame (1) and a planter main frame (26), and also comprises a parallelogram-shaped hydraulic folding beam frame (2). The mounting frame (1) is fixedly disposed at a front end of the parallelogram-shaped hydraulic folding beam frame (2), and the planter main frame (26) is disposed behind the parallelogram-shaped hydraulic folding beam frame (2). The parallelogram-shaped hydraulic folding beam frame (2) comprises a support main beam frame (46), a middle connecting beam frame (44), an outward extending folding beam frame (42) and a parallel cross rod (48). The support main beam frame (46), the middle connecting beam frame (44) and the parallel cross rod (48) constitute a parallelogram-shaped structure. The planter main frame (26) comprises a middle planter axle (36) and side planter axles (33). The middle planter axle (36) is located between two side planter axles (33). The two side planter axles (33) are connected to the outward extending folding beam frame (42) through a wide ground-contour following mechanism (29) respectively. The planter has a compact structure, complete functions, high operation efficiency and good ground-contour following capability, and integrates multiple processes.Linvention concerne une planteuse darachide pliable de grande taille à quatre nervures et huit rangées, comportant un cadre de montage (1) et un cadre principal de planteuse (26), et comprenant également un cadre de profilé pliant hydraulique en forme de parallélogramme (2).
