Digging a hole for a new tree with a shovel is a miserable workout that ends with a hole too shallow and a back that’s done for the week. A gas-powered or electric earth auger turns that chore into a minute of guided drilling, and the right one pays for itself the first afternoon you use it. This guide covers only augers that reach the 18–24 inch depth and 8–12 inch width needed for tree root balls.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Planting a small orchard or a single shade tree starts with the right auger for planting trees—you need enough engine power to dig, a bit size that matches your trees, and a weight you can actually lift and control.
Our Picks at a Glance
How To Choose The Best Auger For Planting Trees
Planting a tree is different from setting a fence post. A tree needs a hole wide enough for its root ball and deep enough for the root flare to sit at ground level, which usually means at least 18 to 24 inches down. That means the bit diameter, engine torque, and shaft length are the specs that matter most.
Match the bit to the root ball
The cutting diameter of the auger bit decides how wide your hole will be. A 6-inch bit suits small shrubs and saplings, while an 8-inch bit is the balance for most container-grown trees. If you’re planting larger balled-and-burlapped specimens, a 10-inch or 12-inch bit gives the root system room to spread without circling.
Gas power versus cordless convenience
Gas engines in the 43cc to 72cc range deliver the raw torque needed to chew through heavy clay and packed soil all day without stopping. Cordless models trade that endurance for instant start and zero fuel mixing, making them ideal for lighter soil and smaller planting sessions. Match your daily hole count to the engine’s endurance: gas for heavy all-day work, cordless for lighter sessions.
Don’t forget the extension rod
A longer auger shaft or an extension rod lets you drill deeper without bending over, which protects your back during a long planting run. Some kits include a 60cm extension or an 8-inch extension bar specifically so you can reach proper tree depth without kneeling. Check whether the kit includes one before you buy.

In‑Depth Reviews
1. Earthquake E43 Earth Auger Powerhead
Our pick — 4.5★ from 700+ verified ratings; the strongest balance of quality and price.
The 36-inch shaft that lets you stand tall while drilling deep tree holes.
The 36-inch auger length is 20% longer than the VEVOR’s 30-inch shaft, reducing bending and improving leverage for deep planting. The 8-inch cutting diameter is the right fit for most container trees, and the fishtail point plus replaceable blades are built to survive rocky ground.
The 43cc Viper engine starts easily and delivers the kind of power that chews through heavy clay, which is the thing owners praise most — drilling performance gets the most shout-outs by far. Buyers report digging holes 8 to 44 inches deep and 10 inches wide without strain, and the steel-welded handlebars with anti-vibration foam grips keep the shaking out of your hands.
The crowd favorite here holds a 4.5-star rating across 700+ owners, and the 5-year limited warranty is a meaningful safety net that budget rivals don’t offer. The trade-off is no reverse function, so hitting buried rock means manually pulling the bit out.
Why It Wins
- 36-inch auger keeps you upright while drilling
- American-made with a 5-year limited warranty
- Replaceable blades and Flex Coil shock absorber
- Industrial air filtration keeps dirt out of the engine
What To Know
- No reverse feature for stuck bits
- 34-pound weight demands some arm strength
- Plastic throttle lever feels light to some owners
Reach for this if: you’re planting a serious number of trees in tough soil and want a machine that’ll last years, not a season.
Look elsewhere if: your ground is full of buried rocks and you need a reverse function to back the bit out.
2. VEVOR Post Hole Digger 43cc
The low-cost gas auger that turns a two-hour digging job into ten minutes.
A 43cc engine with 1250W and 9350 RPM costs less than most rentals, making it a budget standout. The 30-inch alloy steel auger drills deep holes without bending, and the 1.2L fuel tank means you can dig multiple holes before refueling.
The 1.2m pull cord is half again longer than a standard cord, which makes that first start noticeably easier. What wins people over is the sheer time-saving — owners mention cutting fence-building time in half and digging 9 holes without a single missed start. The review pages sum it up: “dug 9 holes never missed a lick, i would recommend this product 100%”.
Reliability is the most-discussed aspect, and it’s a mixed bag. Some units work flawlessly, but a number of customers note the tool stopping after a single hole and a few arrived missing parts. At this price, you’re gambling on quality control.
Smart money move: if your budget is tight and your planting list is short, this gets the job done for a fraction of the premium cost — just inspect every bolt before your first start.
Best if: you need a working gas auger for occasional tree planting and fence work without spending premium money.
Think twice if: you’re planting dozens of trees annually — the durability questions make a longer-warranty pick a safer long-term buy.
3. GardenTrax Earth Auger Combo 43cc
Reliability that chews through West Virginia rocky soil without complaint.
The 43cc 2-cycle engine here is built around one trait owners praise most: reliability, with nearly 40 buyers calling it out as the standout feature. It powers through hard red clay and rocky soil, and the replaceable fishtail point handles everything from loose sand to packed ground. The full-wrap foam grips with built-in shock absorption keep hand fatigue low during a long planting day.
The 8-inch by 36-inch auger bit matches the Earthquake’s length advantage, and the 7/8-inch output shaft fits most standard auger bits if you want to swap sizes later. Owners digging 20 fence holes in a day report clean 8-inch by 3-foot holes with the engine running flawlessly start to finish, and the weight sits light enough for one person to manage solo.
The 4.6-star rating across 200+ owners makes this the highest-scored gas pick in this lineup. The catch is that lightweight frame kicks hard in tough ground, and the steep auger ramp can let dirt slide back into the hole if you don’t clear it promptly. One owner noted it tears roots up to 1.5 inches, but large rocks stall the clutch and need a manual digger to extract.
Balanced verdict: the GardenTrax delivers premium reliability at a mid-range price, making it the safest all-rounder for first-time tree planters who want to avoid budget gamble.
Choose this for: dependable one-person digging in mixed soil where you want proven reliability over raw power.
Pass if: you’re dealing with dense clay that requires constant plunging — this one needs patience in the hardest ground.
4. DC HOUSE 52cc Gas Earth Auger
Two bits in the box mean one auger for saplings and full-size trees.
The headline feature is the included pair of drill bits — a 6-inch for smaller saplings and a 10-inch for bigger root balls — both mounting on a standard 3/4-inch shaft. That flexibility makes this the most versatile single purchase in this lineup, covering everything from bulb beds to substantial tree planting without buying extra parts. The 52cc engine pushes 1800 watts of power through heavy soil.
Reliability is the aspect owners praise most here, with well over a hundred buyers calling it out, and the ergonomic butterfly handles make one-person operation genuinely comfortable. The all-in-one switch keeps the throttle at your fingertips, and reviewers point out digging 30 holes in a single day without the engine complaining. Even a 66-year-old operator found it manageable with a helper holding on.
There’s a durability catch that shows up repeatedly: the choke lever tends to break on early use. The good news is shoppers say the primer bulb still starts the engine without the choke, so it’s an annoyance rather than a dealbreaker. The 4.3-star rating across nearly a thousand owners reflects that the core machine works well despite the plastic lever.
The Flexibility
- 6-inch and 10-inch bits included
- 1800W of power for heavy digging
- Light enough for one or two-person use
- EPA-certified engine
The Durability Note
- Choke lever breaks on early use for some
- Grease fittings arrived empty — pre-grease before first job
- Strong arms needed for big roots
Grab this if: you want one machine that handles both small saplings and large trees with the included bits.
Know before buying: budget a few minutes to pre-grease the fittings and expect the choke lever to be the weak point.
5. DC HOUSE 1500W Electric Post Hole Digger
No fuel mixing, no pull starts, just a 1500W motor that rips through roots.
If the idea of mixing gas and oil puts you off, this corded electric auger removes that whole hassle. The 1500W motor delivers 90 ft-lb of torque at 270 RPM, which translates to real digging power without any of the engine maintenance. The 6-inch bit handles tree planting duties, and the standard 3/4-inch drive shaft accepts most replacement augers if you need an 8-inch.
Quality is what owners praise most, and the aluminum motor housing with shock-absorbing nylon body backs that up. The reverse function is a genuine lifesaver — flip the switch to the “II” position and the bit spins backward to clear soil and unstick from roots. Buyers report digging 100+ deep holes with zero issues and handling 5-inch rocks that would stall lesser machines.
The 4.6-star rating across 86 owners is the joint-highest in this lineup, and the speed is genuinely impressive — one owner dug 40-inch holes in about 10 minutes each in heavy clay. The hard requirement is a decent extension cord: this motor draws serious amperage, and a thin 100-foot cord will burn it out. It’s also tethered to an outlet, so the planting site needs to be within reach.
The electric advantage: instant power, zero fuel smell, and a reverse button that makes stuck bits a non-issue — just bring a heavy-duty cord and an outlet nearby.
Perfect for: homeowners planting a handful of trees near the house who hate fuel mixing and want quiet, clean operation.
skip it if: your planting sites are far from power outlets or you need the portability of gas or battery.
6. 72CC Post Hole Digger with 6 & 8 Inch Bits
A 72cc torque monster that starts first pull and digs through heavy clay.
The 72cc gasoline engine sets this apart from the 43cc crowd, delivering the kind of low-end grunt that makes heavy clay and buried roots an afterthought. The kit comes complete with both a 6-inch and 8-inch double-sheet drill bit plus a 60cm extension rod, so you have the flexibility to match the hole to the tree size. Owners describe being blown away by the performance in heavy clay.
Functionality is the aspect owners praise most, with over 30 calling it out as the standout trait. The easy-start system with manual recoil requires minimal effort, and the ergonomic hand grips with finger throttle give you precise speed control. One owner went down 24 inches for fence posts without any problem, and another dug through heavy clay and roots on the first try.
The 4.4-star rating across nearly 200 owners is solid, but there’s a durability caveat worth knowing: the handles can bend under sustained pressure after a few uses. The right-side handle bending is a recurring theme in ownership reports, so treat the bars with care during hard digging. Despite that, most owners say it’s a great machine for the money.
Torque first, finesse second: this one out-muscles smaller engines on tough soil, but the handlebars are the part to watch under heavy strain.
Go with this: if your planting ground is hard-packed or root-filled and you want maximum torque without paying premium prices.
Be aware: the handle durability means it’s best for seasonal use, not constant commercial workload.
7. NEO-TEC 72CC Post Hole Digger
One powerhead that drills lake ice in winter and hardpan clay in summer.
This dual-purpose machine is the rare auger that earns its storage space year-round. The 72cc 2-stroke engine delivers maximum low-end torque through hardpan clay, compacted soil, roots, and even frozen ground, then switches to ice drilling when the lake freezes. The kit includes a 6-inch bit for tree planting and bulb beds, a 10-inch bit for fence posts and deck footings, plus an 8-inch extension rod for deeper holes.
Quality is the aspect owners praise most, and the build shows it at 39.8 pounds of heavy-duty construction. Both bits mount to the 7/8-inch round drive shaft, and the 25:1 gas-to-oil mix keeps things simple. Owners digging through caliche and dry rocky soil report the machine halving their work time and saving serious back strain. It drilled 14 two-foot holes in rocky clay with ease.
The 4.5-star rating across over 100 owners reflects genuine satisfaction, but there are two setup notes to flag. The gearbox ships dry, so you must grease it via the zerk fitting before first use, and some owners recommend removing the throttle trigger lock for safety. Also, this unit is NOT CARB certified, so it cannot be shipped to California — check your state before ordering.
Year-Round Value
- Dual-purpose ice and earth drilling
- 6-inch and 10-inch bits plus extension rod
- 72cc engine powers through frozen ground
- Quality build praised by owners
Setup Requirements
- Gearbox ships dry — grease before first use
- Not CARB certified, banned in California
- 39.8 pounds is the heaviest in this lineup
Pick this for: the rare buyer who wants one machine for both winter ice fishing and summer tree planting.
Check first: the California shipping restriction and the required pre-greasing before your first start.
8. PROYAMA 54cc Post Hole Digger
The widest bit selection in this lineup, up to a 12-inch hole for big root balls.
For planting large trees, the included 12-inch drill bit is the reason to look here — none of the other picks in this list offer that width straight from the start. The 54cc 2-cycle engine delivers 2.4 HP and 1300 watts of power, and the kit includes 4-inch, 6-inch, 8-inch, and 12-inch bits plus 12-inch and 20-inch extension rods. That’s a complete system for anything from saplings to substantial specimens.
Performance is the aspect owners praise most, with over 40 calling it the standout trait. The EPA-certified engine runs on a 50:1 gas-to-oil mix and starts easily every time, cutting through clay soil fast. Owners mention cutting through smaller roots and completing 60 eight-inch holes in a single day. At 24.2 pounds, it’s one of the lighter full-size gas augers here, which helps during long planting sessions.
The 4.2-star rating across 500+ owners is the lowest in this lineup, and the reason is durability: multiple customers note the unit breaking after initial use, and one couldn’t get their unit to start at all. There’s also a safety note — the torque is strong enough to twist the auger out of your hands if it snags a root, so hold on tight. This one rewards careful owners and punishes carelessness.
Width wins: the 12-inch bit makes this the go-to for large root balls, but the durability reports mean it’s a calculated risk compared to the higher-rated picks.
Choose this: if planting big balled-and-burlapped trees demands a 12-inch hole and you want the bits included.
Hesitate if: you need guaranteed long-term reliability — the quality control is more inconsistent here than on the top picks.
9. WORX Cordless Earth Auger WG865
The brushless battery auger that stops instead of tearing your arm off.
This is the pick that redefines what a cordless auger can do. The 40V brushless motor delivers power equivalent to a 45cc gas engine, with 59 ft-lb of torque and 220 RPM speed, yet weighs just 26.9 pounds without the battery. The anti-kickback system is the standout safety feature — when the bit hits a root or rock, the motor cuts power instead of wrenching the handles out of your hands.
The two-speed design gives you low speed for soil digging and high speed for ice drilling, plus a reverse function for easy bit pull-out. The tool-less auger bit change means swapping sizes takes seconds, and it’s compatible with the 8-inch ice auger bit on the market. Owners digging 36 acres of horse fence report 3-foot holes in 30 seconds, and the safety system earns genuine love for not yanking arms.
The included two lithium-ion batteries dug 4 holes on a single charge, which is the honest limitation — for a full day of commercial planting you’ll want spare batteries. The 4.5-star rating across just 37 owners is newer and less proven than the gas picks, and one unfortunate unit arrived dead on arrival. The PowerShare system means the batteries work across the WORX tool lineup, which softens the cost for existing owners.
The Cordless Appeal
- Anti-kickback stops on rocks instead of twisting your arms
- Reverse function for stuck bits
- Tool-less bit change
- No fuel, no pull-start hassle
The Battery Reality
- Two batteries dug 4 holes — big jobs need spares
- Only 37 owners so far, less long-term data
- Premium price for the cordless convenience
Ideal for: homeowners who want gas-level power without the fuel smell, and anyone worried about kickback injuries.
The trade-off: battery runtime caps your daily hole count unless you invest in extra packs.
Understanding the Specs
Cutting Diameter
The width of the hole the auger bit carves. A 6-inch bit suits small saplings, 8-inch handles most container trees, and 10 to 12-inch bits are for large root balls. Match the bit to the root ball’s width so the roots can spread without circling.
Engine Displacement
The engine size in cubic centimeters (cc) determines raw power. A 43cc engine handles normal soil and occasional use, while 52 to 72cc engines chew through heavy clay, roots, and frozen ground. Bigger cc means more torque to twist the bit through tough earth.

Final Thoughts: The Verdict
The best auger for planting trees for most people is the Earthquake E43 because its 36-inch shaft and 8-inch bit dig proper tree holes while you stand upright, backed by a 5-year warranty. If you want the flexibility of multiple bit sizes without buying extras, the DC HOUSE 52cc delivers a 6-inch and 10-inch pair for saplings and full trees alike. And for a clean, quiet, cordless option that refuses to yank your arms on rocks, the WORX WG865 is the one to reach for.
