A potato planter for a market garden needs to hit a narrow window: small enough to run behind a 25-45HP compact tractor, precise enough to space seed pieces evenly, and simple enough that one person can run it without a second operator on the hopper.
- Bomet Single Row Potato Planter at $3,495 is the safe pick for a market garden potato planter under 1 acre.
- Bomet 2 Row Potato Planter at $4,895 doubles throughput for growers running more than three beds a week.
- Ground-driven planters need forward motion, not a PTO shaft, so most run behind tractors from 20HP up.
- Skip garlic and bulb planters for potato work in 2026 season; hopper geometry suits bulbs, not seed pieces.
- Pair any planter with a disc ridger for hilling once plants emerge above the row.
Why this matters
Most market gardens in New Zealand plant potatoes by hand or with a single-row walk-behind unit, and both hit a wall past a quarter acre. A tractor-mounted planter cuts labour hours on the planting pass and gets seed depth and spacing consistent row to row, which matters more for yield than most growers expect. Get the bed prep wrong first, though, and the planter itself won't fix uneven ground - land prep with a plough built for small-scale market gardens still comes before any planter goes into the paddock.
Who this is for
This guide is for market garden operators running 0.25 to 5 acres of potatoes on a compact or sub-compact tractor, not commercial growers running 20+ hectare centre-pivot blocks. If you're planting by hand right now and looking at your first mechanised pass, or you've outgrown a single walk-behind unit, the picks below are sized for your scale.
What to look for in a potato planter for a market garden
Row count matched to your bed width
A single-row unit suits growers working 750-900mm beds one pass at a time; a two-row unit only pays off once you're planting more than 3-4 beds in a session. Buying two rows too early means towing extra weight and width through gateways you don't need to.
Ground-driven vs PTO-driven mechanism
Ground-driven planters use wheel rotation to cycle the seed cups, so they work at walking pace behind almost any tractor with a 3-point linkage - no PTO shaft required. PTO-driven diggers, by contrast, need a live PTO output and a minimum tractor HP rating, which matters at harvest time rather than planting time.
Seed spacing and hopper capacity
Spacing accuracy directly sets your plant population per row, and hopper capacity sets how often you stop to refill mid-pass. A hopper that needs topping up every 20 metres turns a planting day into a stop-start exercise.
Tractor HP and linkage category compatibility
Most ground-driven potato planters sit on a Category 1 or Category 2 3-point linkage and want 38HP or more to lift and tow comfortably on sloped ground. Check your tractor's lift capacity against the planter's operating weight before you buy, not after delivery.
Seedbed condition going in
A planter drops seed into a furrow it opens itself, but it can't fix a lumpy, unworked bed. Fine, even tilth from a rotary hoe pass gives seed pieces consistent soil contact - see the dedicated guide on rotary hoes for market garden seedbed prep if your beds still have clods bigger than a fist.
Hilling and ridging after emergence
Potatoes need soil mounded over the row as they grow, both to protect tubers from sunlight greening and to smother early weeds. A disc ridger bed former handles this pass separately from the planter itself - don't expect the planter to do double duty here.
Top picks
Bomet Single Row Potato Planter - the entry pick. Priced at $3,495, this is a ground-driven single-row unit built by Bomet, one of Europe's established agricultural implement manufacturers. It suits growers under an acre who want one clean planting pass without a PTO connection. Buy if you're planting under 0.5 acres and running a smaller compact tractor.
Bomet 2 Row Potato Planter (Gemini S239) - the throughput pick. At $4,895, this doubles the row count of the single-row unit for a roughly 40% price jump, and it's the right call once your planting day involves more than three or four beds. Buy if your acreage has grown past what a single-row pass can clear in a morning.
Single Row Automatic Potato Digger PTO - the budget harvest partner. At $2,895, this is a compact PTO-driven digger, not a planter, but it belongs in the same buying decision because it closes the loop on the same rows you plant in spring. Consider it alongside either planter above if you're currently lifting potatoes by hand.
Bomet Single Row Potato Digger/Harvester - the higher-capacity harvest pick. At $6,595, this PTO-driven harvester handles heavier ground and larger tuber loads than the budget digger. Consider it if your soil type is heavier clay or your beds run longer than a typical market garden plot.
What to avoid
- Garlic and bulb planters marketed as "general purpose." The automatic garlic planters in the Implements Direct range are built for garlic, broad beans, onions, tulip bulbs and saffron - the hopper cup geometry doesn't suit seed potato pieces, and forcing it will jam the metering wheel.
- Undersized linkage on a full-size planter. A Category 2-only planter won't mount on a tractor fitted with a lightweight Category 1 hitch without an adaptor, and towing an oversized planter on a sub-30HP tractor strains the lift arms on hillside blocks.
- Skipping the ridging pass. Planting without a follow-up hilling pass leaves tubers exposed to light and gives weeds a head start in the open row - budget for a bed former as a second implement, not an afterthought.

| Bomet 2 Row Potato Planter | 2 rows | Ground-driven | $4,895 | 1-5 acre market gardens | Buy |
| Single Row Automatic Potato Digger PTO | 1 row | PTO-driven | $2,895 | Light soil, small tractors | Consider |

Where to buy
Buy from a supplier that lists 3-point linkage category and hitch weight on the product page, not just a photo - hitch mismatch is the most common return reason on tractor implements in 2026. Confirm freight-to-farm delivery is included before you compare price across two listings; a cheaper unit that arrives on a courier pallet you have to unload yourself isn't actually cheaper. Ask whether the seller stocks spare seed cups and drive chains locally, since a planter sitting idle mid-planting-window costs more than the part itself.
FAQ
What's the best potato planter for a small market garden in 2026?
The Bomet Single Row Potato Planter at $3,495 is the best fit for market gardens under an acre because it's ground-driven and needs no PTO connection. Growers planting more than three or four beds a session should step up to the Bomet 2 Row Potato Planter at $4,895.
Is a two-row potato planter better than a single-row unit?
A two-row planter cuts planting time roughly in half but adds width and towed weight you don't need under half an acre. Single-row units suit smaller plots and tighter gateways better than two-row models.
How much horsepower do I need for a potato planter?
Ground-driven potato planters generally need 38HP or more to lift and tow safely, especially on sloped ground. Check the planter's operating weight against your tractor's rear lift capacity before buying.
Do potato planters need a PTO shaft?
No - most market garden potato planters, including the Bomet Single Row and 2 Row models, are ground-driven and cycle off wheel rotation, not a PTO output. PTO drive is more common on harvesting equipment like potato diggers.
Can a garlic planter also plant potatoes?
No - garlic planters are built for garlic, broad beans, onions, tulip bulbs and saffron, and the hopper cup geometry doesn't handle seed potato pieces reliably. Use a dedicated potato planter to avoid jamming the metering wheel.
How much does a potato planter cost in New Zealand?
Single-row ground-driven potato planters start around $3,495, and two-row models run about $4,895 in 2026. PTO-driven diggers for the harvest side range from $2,895 to $6,595 depending on capacity.
Do I need a separate implement for hilling potatoes after planting?
Yes - a disc ridger or bed former handles the hilling pass separately from the planter, mounding soil over the row as plants emerge. Skipping this step exposes tubers to light and lets weeds establish in the open row.
What seedbed prep does a potato planter need before use?
A fine, even tilth from a rotary hoe pass gives seed pieces consistent soil contact and lets the planter's furrow opener run true. Beds with clods larger than a fist should get a cultivation pass first.
One last thing
The row spacing decision matters more than most growers budget time for: 750mm rows suit most home-market and CSA-scale plantings, but if you're supplying wholesale, check what row spacing your buyer's grading equipment expects before you set the planter - re-spacing an established bed mid-season isn't an option.
