An improved, more versatile applicator (10) for precisely dispensing granular chemicals, fertilizers or seed, includes a hopper (14) with a metering assembly (40) mounted over a material discharge opening (34) in an inclined wall of the closed, convergent bottom end (18) of the hopper. The metering assembly (40), which is preferably removably secured to the hopper (14), includes a plurality of individual sets of metering wheels (64), receivers (56) and gate plates (60) for precise control and more tolerance to tilt. The metering assembly (40) is also adapted to facilitate thorough clean-out of the hopper (14) as well as removal and replacement of the metering wheels (64) without emptying the hopper.
