Abstract: A trailer-type apparatus for planting canister contained tree seedlings, or the like, includes a furrow forming plow followed by a backfill blade sequentially operated for forming the furrow and covering the roots of a seedling deposited in the furrow. A belt-type conveyor, provided with transverse recesses, receives canister contained tree seedlings from a supply hopper and deposits the seedlings in sequence on a seedling supporting ramp. A pressure cylinder plunger separates the seedling from its canister and deposits it on a pivoting platform lowering the seedling by gravity into a sleeve chute where it is temporarily supported until a quantity of water, released from an adjacent tank, washes the seedling out of the chute to fall into an underlying furrow prior to backfilling.
