Sun Joe or Earthwise Tillers? Which Is Better for Small Gardens?

For most small home gardens, Sun Joe is the better choice if you need to break up tougher or compacted soil, while Earthwise can make more sense if you prioritize lighter handling and routine cultivation. The right pick depends less on brand name and more on soil condition, garden size, tilling width, weight, and how often you plan to use the machine.

If you are comparing the popular 16-inch corded models, Sun Joe offers models such as the 12-amp TJ603E and 13.5-amp TJ604E, while Earthwise offers models such as the 12.5-amp TC70125EW. These are compact electric tillers designed for residential gardening rather than replacing a heavy-duty gas rototiller.

Sun Joe’s TJ603E, for example, has a 12-amp motor, six steel tilling blades, a maximum 16-inch working width, and up to 8 inches of cultivating depth. Its listed weight is 27.1 pounds.

The Sun Joe TJ604E steps up to a 13.5-amp motor while keeping the 16-inch working width.

That makes the exact model more important than simply choosing between the two brands.

Sun Joe Is Better for Tougher Soil

If your small garden has compacted soil, clay, old roots, or a bed that has not been worked for several seasons, Sun Joe gets the edge.

The 12-amp TJ603E is designed to work up to 16 inches wide and 8 inches deep, while the 13.5-amp TJ604E provides even more motor power.

That extra power matters because electric tillers can struggle when the tines repeatedly hit hard ground.

Independent testing also rates the Sun Joe 12-amp 16-inch model highly for performance and notes that its motor is capable of handling tougher soil.

There is an important limit, though. A small electric tiller is not a substitute for a heavy-duty gas tiller when you are trying to break completely untouched ground over a large area.

For a backyard vegetable bed, flower bed, or a relatively small patch, Sun Joe’s power is much more useful.

Earthwise Makes More Sense for Light Cultivation

Earthwise is worth considering when your garden soil is already reasonably loose and your main jobs are:

• Loosening soil before planting
• Mixing compost into existing beds
• Removing small weeds
• Maintaining vegetable beds
• Working around established garden areas
• Cultivating relatively small sections

The Earthwise 120V 16-inch model is also positioned as a serious corded electric tiller. BobVilas 2026 testing gave the Earthwise 16-inch model strong marks for ease of use, performance, durability, and value.

Some Earthwise models are considerably smaller and lighter than the larger 16-inch machines. That can be useful when your garden contains narrow beds or areas where you need more control rather than maximum ground coverage.

So the Earthwise name alone does not tell you how a machine will behave. Compare the specific model.

Which One Is Easier to Handle?

For a small garden, maneuverability can matter almost as much as motor power.

A wider, more powerful tiller can finish an open garden bed quickly, but it can feel less convenient in tight spaces. A smaller cultivator can be easier to guide between plants and around established beds.

The Sun Joe TJ603E weighs about 27.1 pounds, according to its operator’s manual.

That is manageable for many homeowners, but it is still enough weight to make repeated lifting or carrying noticeable.

When Sun Joe’s weight helps

Weight is not always a disadvantage. When the tines are trying to penetrate firm soil, a little more machine weight can help keep the tiller engaged with the ground instead of bouncing across the surface.

This is one reason a small but powerful tiller can feel more effective in hard soil.

When a lighter Earthwise model helps

If you are cultivating an established bed and frequently need to reposition the machine, a lighter Earthwise model can be more comfortable.

For someone working in several small beds rather than one open plot, easy movement may be more valuable than maximum digging power.

Tilling Width Matters More Than It Looks

Both brands offer models around the 16-inch class, but Earthwise and Sun Joe also sell smaller cultivators.

A 16-inch tilling width means you can cover more soil with each pass. That is helpful when preparing a rectangular vegetable garden.

But wider is not automatically better.

Imagine two small gardens:

Example 1: 4-by-8-foot vegetable bed

A 16-inch tiller is a good match because there is enough open space to make repeated passes without constantly worrying about nearby plants.

Example 2: Narrow flower beds with established plants

A smaller, narrower cultivator may be easier to control. You do not necessarily need a wide machine if precision is the priority.

For small gardens, choose the working width based on the space between plants and beds, not just the largest number on the product box.

What About Tilling Depth?

Depth is another area where shoppers can easily overestimate what they need.

The Sun Joe TJ603E can cultivate up to 8 inches deep.

That is plenty for many residential garden-preparation jobs.

But you should not automatically till as deeply as possible every time. Garden soil can often be damaged by unnecessary aggressive tilling, particularly when the soil is wet.

For routine maintenance, shallow cultivation may be enough. Deeper tilling is more relevant when preparing a new bed or incorporating amendments into suitable soil.

Sun Joe vs. Earthwise for Vegetable Gardens

For a typical backyard vegetable garden, I would give Sun Joe the advantage when the soil needs real breaking up.

Its combination of motor power, steel tines, 16-inch width, and up-to-8-inch depth makes it well suited to preparing open garden beds. The TJ603E specifications confirm those core capabilities.

Earthwise becomes more attractive when the garden is already established and you mainly need to cultivate and loosen soil.

Choose Sun Joe if:

• Your soil is compacted
• You are preparing a new garden bed
• You want stronger soil-breaking performance
• You have an open garden area
• You want a 16-inch working width
• You prefer corded power over battery charging

Choose Earthwise if:

• Your soil is already fairly workable
• You prioritize maneuverability
• Your garden has tighter spaces
• You mainly maintain existing beds
• You want a lighter-duty cultivator for regular garden work

Sun Joe vs. Earthwise for Raised Beds

Raised beds change the decision.

If the raised bed has loose soil that you refresh every year, you may not need the strongest tiller available. A lighter cultivator can be easier to control and less likely to throw soil outside the bed.

On the other hand, if a raised bed has become hard and compacted, Sun Joe’s stronger models can be useful.

Sun Joe customer reviews for the TJ603E include positive reports of using the machine in raised garden beds, although users also note that performance depends heavily on how hard the soil is.

The practical lesson is simple: loose raised-bed soil favors control; hard raised-bed soil favors power.

What You Should Not Expect From Either Brand

Neither Sun Joe nor Earthwise should be treated like a commercial agricultural tiller.

Small electric tillers have clear limits.

They can be excellent for:

• Vegetable gardens
• Flower beds
• Small planting areas
• Soil maintenance
• Weed cultivation
• Mixing suitable soil amendments

They are less suitable for:

• Large fields
• Extensive untouched ground
• Very rocky soil
• Thick sod over large areas
• Large areas of heavily compacted clay

User feedback on electric tillers also shows why expectations matter. Some gardeners report that lightweight electric machines can bounce on hard ground or struggle to dig deeply, especially in heavy clay.

If you are creating a large new garden on hard ground, renting a heavier tiller for the initial preparation and using a small electric machine for later maintenance can sometimes be a more practical approach.

Corded Power Is a Real Trade-Off

Both of these brands are commonly compared in the corded-electric category, so there is one issue you cannot ignore: the power cord.

A corded tiller does not have the battery-runtime limitation of a cordless model. You can keep working as long as you have electrical power and the machine is being used according to its instructions.

But you must manage the extension cord carefully.

Sun Joe’s manual specifically requires an outdoor-suitable extension cord and warns users to keep the cord away from moving parts, heat, oil, and sharp edges.

Never treat the cord as an afterthought. Plan your route through the garden before starting.

Also avoid using a corded tiller in rain or wet conditions. The manufacturer’s safety instructions specifically warn against operation in wet or damp locations.

Which One Is Better for Beginners?

For a beginner who has never used a tiller, either can work, but the better choice depends on the soil.

If your garden is already loose and you mainly need light cultivation, a smaller Earthwise model can be less intimidating.

If you need to prepare a garden where the soil is noticeably hard, Sun Joe’s stronger 16-inch models give you more capability.

The key is not to force the machine. Let the tines do the work and make multiple passes when necessary rather than trying to push a small electric tiller aggressively through ground it cannot handle.

Which One Offers Better Value?

Value depends on how much capability you actually need.

Buying a high-powered tiller for a tiny established flower bed may mean paying for performance you rarely use. On the other hand, choosing an underpowered cultivator for hard clay can leave you frustrated and may force you to rent another machine.

For that reason:

Best value for tough small-garden work: Sun Joe

Best value for lighter cultivation: Earthwise

Best overall choice for mixed soil conditions: Sun Joe

Independent testing has also placed both Sun Joe’s 12-amp 16-inch model and Earthwise’s 120V 16-inch model among strong electric-tiller options, which supports the idea that this is less about finding a universally superior brand and more about matching the machine to the job.

A Common Mistake: Choosing by Amp Rating Alone

A higher amp number does not automatically mean a better tiller.

Motor power matters, but so do:

• Tine design
• Working width
• Machine weight
• Tilling depth
• Soil condition
• Garden layout
• Operator control
• Cord management
• How frequently you use the machine

For example, a 16-inch machine may cover more ground but be less convenient in a narrow bed than a smaller cultivator.

Likewise, a powerful tiller can be unnecessary if you only loosen already-soft potting or garden soil.

Look at the entire machine rather than one specification.

So, Sun Joe or Earthwise?

For most homeowners asking specifically about small gardens, I would choose Sun Joe when the garden needs actual tilling, especially if the soil is compacted or you are creating a new bed.

Its common 16-inch models provide strong performance, with the TJ603E rated at 12 amps and the TJ604E at 13.5 amps. Both are built around a 16-inch working width, while the TJ603E is rated for up to 8 inches of cultivating depth.

I would choose Earthwise when the job is mostly light cultivation and maneuverability is more important than maximum power.

The biggest mistake is buying based on brand alone. Check the exact model, then match its width, weight, power, and digging capability to your soil and garden layout.

Frequently Asked Questions

Is Sun Joe better than Earthwise for hard soil?

Generally, Sun Joe is the stronger choice when hard or compacted soil is the main concern. Its 12-amp and 13.5-amp 16-inch models provide substantial power for residential electric tilling, although very hard or large areas may still require a heavier machine.

Are Sun Joe and Earthwise tillers good for small vegetable gardens?

Yes. Both brands offer electric tillers suitable for many small residential gardens. Sun Joe is particularly appealing when you need to prepare tougher soil, while a smaller Earthwise cultivator can be a good fit for maintaining already-worked beds.

Should I buy a tiller or a cultivator for a small garden?

Choose a tiller when you need to break up compacted soil or prepare a new bed. Choose a cultivator when the soil is already workable and you mainly need to loosen the surface, mix in material, or control small weeds.

The Bottom Line

Sun Joe is the better all-around pick for most small gardens that need real soil preparation. Its stronger 16-inch electric models offer the power and coverage needed for compacted beds without moving all the way up to a large gas tiller.

Earthwise is the better fit when your garden is already established and you value manageable, lighter-duty cultivation.

Before buying, check your soil first. If you can easily push a garden fork into the bed, prioritize control and size; if the ground is hard and difficult to break, prioritize motor power and tine performance.
