Plant dollies use four 360° swivel/universal wheels with thickened internal construction and a grid-style back plate to distribute load, which lets them carry heavier pots and roll more smoothly.
Lawn rollers are used to flatten and pack down uneven ground—ideal for freshly sown seed, laying sod, repairing frost- or animal-damaged patches—and for rolling both tight areas and larger open spaces.
Plant dollies are described as rolling smoothly over hardwood and wooden floors, concrete, carpet, and patio surfaces.
Yes — you can drill drain holes in the plate if needed, and the castors can be removed to convert the dolly into a planter saucer; sellers also advise measuring the pot’s bottom diameter to ensure a proper fit.
Common round plant dolly diameters in the listings are about 13 inches and 14 inches (listed near 12.99 in and 14.17 in).
The lawn roller is filled through a plug/drain and is listed with a capacity of about 15.9–16 gallons (approximately 60 liters).
Plant dollies help prevent floor wetting during watering, reduce sliding, distribute pot load via a grid back to lower pressure points, increase friction at the pot base to reduce toppling, and protect floors from wear.
The listings give inconsistent empty-weight values: one description states 17.6 lbs (without water or sand) while detailed specs list Net Weight: 22 lbs. The maximum filled weight is listed as 202.2 lbs (with sand). Consider confirming the correct empty weight with the seller or product page.
