If electric cultivators can't provide the gardening power you need, look to a gas-powered cultivator.
With powerful engines, you can take on more daunting tasks.
Also, if you're tackling a big garden, or one far from electricity, there's no cord to tether you down and no battery to charge.
The only decision to make is whether you want a 2-cycle or a 4-cycle cultivator?
A very useful feature found on some gas-powered cultivators is reversible tines. What this means is in the standard position the tines are set to cultivate. When you reverse them, the tines will essentially till the soil.
When the tines are in tilling mode, they will break up and turn the soil, getting it ready for planting. When the tines are in cultivating mode, they will aerate and weed your garden, keeping it in tip-top shape. However, reverse tines won't likely be enough to break hard ground - you'll need a front- or rear-tine tiller for that.
2-cycle engines require a mixture of gas and oil in the fuel tank. Also known as 2-stroke engines, this type of engine is lighter and simpler to maintain than a 4-cycle engine.
2-cycle engines also have the potential to pack about twice the power into the same space as a 4-cycle engine. This combination of light weight and twice the power gives 2-cycle engines a great power-to-weight ratio compared to many 4-cycle engine designs. This makes a 2-cycle engine a lightweight option for powering a cultivator.
Models with 4-cycle engines are very similar to the car you drive – gas goes in the fuel tank and oil goes into the crankcase. They work in the same manner as a car engine as well. They are more fuel efficient than a 2-cycle engine, so you get more “mileage” out of every tank of gas when using your 4-cycle cultivator.
4-cycle engines have the capability to produce more overall power than 2-cycle engines do, although this results in a larger engine in terms of size and weight, which may not be good if you’re lugging around the cultivator all day.
