Lawn and Garden — FAQ
What's the difference between a tiller and cultivator?
Tillers break new, unworked ground and dig deeper. Cultivators mix and aerate existing beds at shallower depths. Most electric models under $150 function as both, with adjustable depths for each task.
Can these tillers break new ground in hard soil?
The Sun Joe corded model can break moderate hardpan and virgin soil. Cordless models struggle with untouched ground—best for previously worked or moderately loose soil. For solid clay, rent a gas rear-tine tiller.
How long do batteries last in real use?
2.0Ah batteries: 15-20 minutes. 4.0Ah batteries: 30-40 minutes. Runtime drops 20% in hard soil versus loose beds. Always keep a spare battery charging for continuous work.
Are corded electric tillers more powerful than cordless?
Yes, significantly. A 13.5-amp corded motor equals 1.6 horsepower—double the torque of 20V cordless models. Corded units maintain full power indefinitely, while cordless loses strength as batteries drain.
Can I use a garden tiller on grass to remove a lawn?
Tillers will tear up grass but leave root clumps that regrow. For lawn removal, use a sod cutter first, then till the soil. The Sun Joe's depth can handle this; cordless models lack the power for thick sod.
What's the best tilling width for a home vegetable garden?
16 inches for large plots (500+ sq ft) to minimize passes. 8-9 inches for raised beds and narrow rows. Most homeowners benefit from 9-inch cordless models for versatility, unless you till large areas annually.
