Gorilla Carts Dump Cart Review: Hauling Mulch, Soil, and Yard Waste

Every spring I order three cubic yards of double-shredded mulch dumped at the end of my driveway, and every spring I've faced the same math problem: how many wheelbarrow trips does it take to move three cubic yards forty feet uphill to the back beds, on knees that aren't getting any younger. Last April I finally did something about it and bought the Gorilla Carts Heavy-Duty Poly Dump Cart, the 6-cubic-foot tub with the 1,200-pound haul capacity. I've now hauled mulch, topsoil, pea gravel, and more yard waste through a full growing season, April through the first hard frost in November, and I want to walk you through exactly what that season looked like, the good parts and the parts I'd tell you about before you buy.

I'd resisted a dump cart for years because the good ones aren't cheap and I wasn't sure I'd use it enough to justify the shelf space. What changed my mind was doing the actual math on my knees and my Saturdays. If a tool saves me two hours of wheelbarrow trips every time a load of mulch shows up, it pays for itself in a season just in the time I get back, never mind the wear and tear it saves my body.

How I've Used It

I've got a half-acre lot with a mix of perennial beds, three raised vegetable beds, and a gravel path I've been slowly building along the side yard. Over the season I used the Gorilla Carts dump cart for three separate mulch deliveries, one big load of screened topsoil for the raised beds, close to a ton of pea gravel hauled in stages for that side path, and then the fall cleanup, which meant hauling leaves and spent perennial stems to the compost pile at the back of the property nearly every weekend in October and November.

That's a wide range of material, from light, fluffy leaves that barely register on a scale to wet, packed mulch and gravel that get heavy fast. I wanted to know if this cart would hold up to the heaviest jobs I had planned, not just look nice hauling a few bags of potting soil, so I loaded it as full as I reasonably could on the mulch and gravel runs rather than babying it.

The first real test came within a week of buying it. My spring mulch delivery landed as a three-cubic-yard pile at the curb, and I filled the 6-cubic-foot tub about six times to move the whole thing back to the beds. With my old wheelbarrow that job used to take most of a Saturday morning and left my lower back aching by lunch. With the Gorilla Cart, I was done in under two hours, and I wasn't nearly as wrecked afterward.

The Poly Tub and the Quick-Release Dump

The tub itself is a heavy-gauge poly, not sheet metal, which was actually a selling point for me. I've had metal wheelbarrows rust through at the seams after a few wet seasons, and poly doesn't have that problem. It also doesn't dent the way metal does when you drop a load of flagstone into it, which I did more than once while building that gravel path.

The quick-release dump mechanism is the feature that sold me in the first place, and it's genuinely the best part of owning this cart. You pull a lever on the side, the tub tips forward on its pivot, and the whole load slides out in seconds instead of you shoveling it back out by hand. Dumping a full load of mulch or gravel exactly where I wanted it, right at the edge of a bed, took maybe five seconds once I got the hang of lining the cart up first.

The one thing I'll flag here is that the poly tub does flex noticeably when it's loaded all the way to the rim with something dense like wet soil or gravel. It never cracked or showed stress marks over the season, but you can see and feel the walls bow out a little under a truly heavy load, and that took some getting used to the first time it happened. It's a normal characteristic of poly construction, not a defect, but nobody warned me about it before I bought mine.

Capacity: What 1,200 Pounds Actually Looks Like

The 1,200-pound rating sounds abstract until you've actually loaded the cart with something dense. Wet, packed mulch runs somewhere around 40 to 50 pounds per cubic foot, so a full 6-cubic-foot tub of soaked mulch can push 250 to 300 pounds on its own. Pea gravel is heavier still, closer to 90 to 100 pounds per cubic foot, so I never filled the tub more than about two-thirds full on the gravel runs or I'd have been well past what I wanted to tow behind my riding mower on uneven ground.

That's the practical lesson from a full season of use: the rated 1,200-pound capacity is real, and I never came close to breaking the cart, but you'll hit a comfortable working limit well before the rated max on anything dense, because the tub fills up in cubic feet long before it fills up in pounds. For lighter material like leaves or mulch, you can load it right to the rim without a second thought.

For the topsoil delivery, I split a half-ton load into four cart trips instead of the eight or nine wheelbarrow trips that same load would have taken me. That's the kind of math that actually changes whether a Saturday project gets finished or gets pushed to next weekend.

The Tires and Towing

The pneumatic tires are, in my opinion, the real difference between this and a cheaper solid-wheel version. My side yard has some rutted, uneven ground where an old fence line used to be, and solid tires transmit every bump straight into your hands or your tow vehicle. The air-filled tires soaked up that rough ground noticeably better, and I never once got the cart stuck the way I used to with my old wheelbarrow's narrow wheel.

I towed it behind my riding mower for the bigger loads, mulch, gravel, and the fall leaf hauls, and the hitch held up fine over dozens of trips. The tongue takes some getting used to on tight turns, especially reversing, and I clipped a raised bed corner once in the first couple weeks before I got a feel for how much wider the cart tracks than the mower alone. By midseason that wasn't an issue anymore, it's just a learning curve worth knowing about going in.

For the smaller loads, hand pruning debris or a few bags of soil, I just pulled it by hand with the tongue handle, and it rolled easily enough across grass and gravel that I didn't bother hitching up the mower for quick jobs.

What Else I Considered

Before I bought this cart, I seriously considered just replacing my aging wheelbarrow with a nicer one instead. A good contractor-grade wheelbarrow with a pneumatic tire runs less money, and for a lot of yards that's genuinely the better tool, especially if you're navigating narrow gates or raised bed rows where a wider dump cart won't fit. I measured my gate width before I bought this cart for exactly that reason, and I'd tell anyone to do the same.

I also looked at a couple of smaller poly cart models with less capacity, thinking a lighter cart would be easier to maneuver. After doing the math on how much material I actually move in a season, mulch deliveries, gravel, soil, and fall cleanup, I decided the smaller capacity would just mean more trips, which defeats the whole point of buying a hauling cart in the first place. Sizing up to the full 6-cubic-foot, 1,200-pound model was the right call for how I actually garden.

Price factored in, but less than I expected going in. This sits in the middle of the dump cart category, not the cheapest option and not the priciest, and after a full season I think the poly tub, the pneumatic tires, and the quick-release dump mechanism earned that middle price. A cheaper cart with a rusting metal tub or solid tires that jar every bump would have cost me more in frustration than the difference in price ever saved.

Where It Struggled

I want to be straight about the tradeoffs, because no tool is perfect for every yard. The cart's width is the biggest one. It doesn't fit through my side gate, which is a standard 36-inch walk gate, so anything I need to move through that gate still goes by wheelbarrow. If your yard has narrow gates or tight side-yard access, measure before you buy, because this cart is meaningfully wider than a standard wheelbarrow.

Assembly took me a little over half an hour the first time, mostly getting the axle bolts aligned and torqued down evenly. It's not difficult, but it's not a five-minute job either, and I'd plan for a real chunk of a Saturday morning to get it built and give the hardware a check before you load it up the first time.

And as I mentioned, the poly tub flex under a truly full, dense load is something you feel and see, even though it never failed on me. If that makes you nervous, loading to about two-thirds capacity on heavy material like gravel or wet soil keeps the tub well within its comfortable working range and still saves you a lot of trips over a wheelbarrow.

With my old wheelbarrow that mulch delivery used to take most of a Saturday morning. With the Gorilla Cart, I was done in under two hours, and that's when I stopped second-guessing what I'd paid for it.

Who This Is For

If you deal with regular deliveries of mulch, soil, or gravel, or you're doing any kind of hardscaping project like a path or a patio base, this cart earns its spot in your shed. It's especially good for gardeners with wider gates or driveway access who move real volume every season, not just an occasional bag of potting mix. Anyone with knee or back concerns will notice the difference the quick-release dump makes over shoveling material back out of a wheelbarrow by hand, and if you've got a riding mower or small tractor to tow it with, the capacity becomes even more useful for bigger properties.

It's also worth it if fall cleanup on your property involves more material than a couple of leaf bags can handle. I moved more leaves and spent perennial stems to my compost pile in one afternoon than I used to manage in an entire weekend of wheelbarrow trips.

Who Should Skip It

If your yard has narrow gates or tight side-yard access like mine does on one side, measure carefully before you buy, because this cart won't fit through a standard walk gate and you'll end up relying on a wheelbarrow for those areas anyway. And if your gardening is mostly container work or small raised beds without much bulk material movement, a nicer wheelbarrow will serve you just as well for a lot less money and a lot less storage space.

If you don't have a mower, small tractor, or ATV to tow it with and you're not planning to hand-pull it regularly, the extra capacity over a wheelbarrow may not be worth the tradeoff in maneuverability, especially on a smaller lot where you're mostly making short trips anyway.
