A heavy-duty seedling planter for reforestation comprises specially configured coulter wheels that form a unique seedbed furrow. An elongated, rigid frame includes a front towing connection, and a rear strut for mounting trailing furrow compaction wheels. The planter is towed over the ground by an agricultural tractor and an operator seated within a cab dispenses seedlings. The coulters are spaced apart from one another along the frame. Both coulters are towed in approximately ten degrees and positively cambered approximately three degrees. The axes of rotation of the coulters are neither coaxial, coincident, collinear nor coplanar. The trailing coulter almost touches the midpoint of the leading coulter. Dual convex packer wheels trailing the frame compress soil, close the furrow, and create twin, parallel irrigation trenches.
