Garden Cart Casters

These garden cart casters and wheels fit yard and nursery carts on grass, gravel, and paved paths. Casters and wheels in this collection range from about 500 to 1,000 lb each. All plate casters use a 4 x 4-1/2 in top plate. Sizes include 10 x 3 semi-pneumatic at 650 lb, 6 x 2 mold-on rubber at 550 lb, 6 x 2 polyurethane (poly or urethane) at 900 to 1,000 lb, a 6 x 2 rubber-on-iron wheel at 500 lb, and 4 x 2 phenolic at 800 lb. Use 10 in semi-pneumatic on soft ground. Polyurethane rolls easiest on pavement. Soft rubber helps when the path has chips or grit. Phenolic stays on smooth concrete. Largest here is 10 in; no 16 or 20 in wagon tires on this page. Capacities below are per caster or wheel unless a listing says set. Indoor plant and platform carts: cart casters. Complete flatbeds: flatbed carts and platform trucks.

Product titles and fields [S1]. All casters use a 4 x 4-1/2 in plate.

Which tread for which ground

Grass, soil and gravel: the 10 x 3 in semi-pneumatic casters. The large, soft wheel rolls over ruts and does not go flat.
Paved paths and driveways: 6 x 2 in polyurethane rolls easiest and carries the most.
Mixed ground: 6 x 2 in mold-on rubber is quieter and grips better than polyurethane.
Smooth concrete only: 4 x 2 in phenolic. Small, hard wheels sink in soft ground.

Replacing a wheel or caster

If the cart has plate casters, match the 4 x 4-1/2 in plate and the bolt pattern. If only the wheel is worn, match the diameter, tread width, bore and hub length. There are no pneumatic tires or wheels larger than 10 in on this page.

Head-term cart casters (indoor plant/platform): cart casters. Complete flatbeds: flatbed carts and platform trucks. Larger air tires: hand truck wheels.
