Quick Answer: For most lawns with real soil compaction, the Brinly PA-482BH 48” tow-behind plug aerator ($409, 32 heat-treated steel tines, 200-lb weight tray) is the best zero-turn mower aerator — it pulls actual 3-inch soil plugs instead of just poking holes, and hitches to the same universal tow point most zero-turns already use. Smaller or tighter lawns do better with the narrower Brinly PA-403BH 40” ($299, 24 tines, 150-lb tray), and anyone with light, already-loose soil who just wants a cheap once-a-year pass can get by with a spike aerator like the Agri-Fab 45-0544 (~$199) — though it won’t relieve real compaction the way a plug unit will.
Compacted soil is the one problem regular mowing can’t fix — water, air, and fertilizer stop reaching the root zone no matter how sharp your blades are or how often a zero-turn passes over it. Aerating breaks that compaction up, and a tow-behind unit lets you do it in a single pass around your normal mowing route instead of renting a walk-behind core aerator for the weekend. Here’s how the tow-behind options compare.
Last updated: September 9, 2026 — re-verified all four prices direct from source. Both Brinly units matched exactly: the PA-482BH still $409 and the PA-403BH still $299, per brinly.com’s own current product pages. The Agri-Fab 45-0299 remained within its published $350-$430 spread (current listings run $357-$380). The Agri-Fab 45-0544 spike aerator held exactly at $199 on Walmart. No price drift found on any of the four.

Best overall: Brinly PA-482BH 48” tow-behind plug aerator
Brinly PA-482BH 48" Tow-Behind Plug Aerator
- 32 heat-treated steel tines pull genuine 3-inch soil plugs, per Brinly's own product spec, rather than just poking a hole that can re-compact around the edges the way a spike does.
- A rigid, fully enclosed 200-lb weight tray lets you add sandbags or weight plates for heavy clay soil, and hitches to the same universal tow point covered in our attachments roundup.
- At roughly $409 direct from Brinly, it's the priciest option here — the premium buys width (fewer passes on a big lawn) and tray capacity for genuinely compacted soil.
Waiting on a replacement tine or hitch pin shouldn’t cost you your once-a-year aeration window — a free 30-day Amazon Prime trial gets small parts like these to your door in two days instead of a week-long dealer order.
This is the pick if your lawn has visible compaction (standing water after rain, hard-packed dirt near paths or play areas) or you’re aerating more than a half-acre in one session.
Best for smaller lawns: Brinly PA-403BH 40” tow-behind plug aerator
Brinly PA-403BH 40" Tow-Behind Plug Aerator
- 24 heat-treated 16-gauge steel plug spoons pull the same 3-inch soil plugs as the 48" model, per Brinly's spec sheet, just across a narrower working width.
- The narrower 40-inch frame is easier to maneuver around beds, trees, and septic lids than the 48-inch unit, at the cost of more passes on a large property.
- A 150-lb weight tray is still enough for most residential soil — heavy clay on a large lot is really where the wider, heavier PA-482BH earns its price difference.
Good for lawns under half an acre or yards with a lot of obstacles, where a narrower unit spends less time being lifted around trees and beds than the 48-inch version.
Best value plug aerator: Agri-Fab 45-0299 48”
Agri-Fab 45-0299 48" Tow-Behind Plug Aerator
- 32 self-sharpening galvanized aeration knives pull 3-inch plugs across a 48-inch width, per Agri-Fab's own spec sheet, matching the Brinly PA-482BH's tine count at a similar or lower price depending on retailer.
- A fully enclosed 140-lb weight tray is a step down from the Brinly's 200 lbs — plenty for typical residential soil, less overhead for genuinely hard clay.
- Pricing runs an unusually wide $350-$430 spread across retailers for this model — worth comparison-shopping before buying rather than assuming any one listing is the best price.
Functionally very close to the Brinly PA-482BH above — the choice mostly comes down to whichever brand is priced lower at the retailer you’re already buying from.
Best budget: Agri-Fab 45-0544 40” spike aerator
Agri-Fab 45-0544 40" Tow-Behind Spike Aerator
- 10 galvanized steel spike disks push into the soil rather than removing a plug — cheaper to build and buy, but the mechanism doesn't relieve compaction the way a plug aerator does.
- Hitches to the same universal tow point as the plug aerators above, so it works behind essentially any zero-turn or a lawn tractor.
- At roughly half the price of a plug aerator, it's a reasonable once-a-year touch-up for lighter, already-loose soil — not the right tool for a lawn with real hard-packed compaction.
This is the right call only if your soil isn’t genuinely compacted and you just want a light, low-cost pass — anyone with standing water after rain or visibly hard-packed dirt should spend the extra money on a plug aerator instead.
What to check before buying
- Plug vs. spike is the real decision, not brand — a plug aerator removes an actual soil core; a spike aerator just pushes a solid tip in, and Penn State Extension notes that lateral push can compress soil against the hole’s sides in heavy clay, worsening compaction instead of fixing it. Stick with a plug aerator unless your soil is already light and loose.
- Zero-turns can safely tow an aerator despite the general towing caveat elsewhere on this site — our zero-turn vs. lawn tractor guide notes zero-turns aren’t built for heavy ground-engaging attachments; a floating-wheel tow-behind aerator, like the tow-behind dethatcher on this site, is a different load class than a plow or tiller and is explicitly manufacturer-rated for ZTR use.
- Aerate before overseeding, not after — the open plug channels give new seed direct soil contact, so most turf programs recommend aerating right before or during overseeding rather than afterward.
- Add weight only for genuinely hard soil — the weight trays on these units are for compacted clay, not routine use; extra weight on already-workable soil just adds wear to the tines and hitch.
- A tow-behind aerator needs somewhere to live in the off-season — see our best zero-turn mower storage shed guide for structures with room for towed implements alongside the mower.
The bottom line
Owners with real soil compaction should buy the Brinly PA-482BH or the similarly specced Agri-Fab 45-0299 — both pull genuine 3-inch soil plugs across a 48-inch width for roughly $350-$430. Smaller or tighter lawns do just as well with the narrower Brinly PA-403BH at around $299. Only reach for the Agri-Fab 45-0544 spike aerator if your soil is already loose and you just want a cheap once-a-year touch-up. See our attachments roundup for the rest of what hitches to that same tow point, or our full zero-turn mower guide if you’re still shopping for the mower itself.
