How to store an excavator bucket properly? – Japanese Natto Kinase Blog

Hey there, fellow construction crew, equipment operators, and even the occasional job site manager who’s ever stared at a worn excavator bucket and thought, “Where do I even put this when I’m not using it?” ???? I’m Jake, part of the team that’s been supplying heavy-duty excavator buckets to job sites across North America for over a decade, and let me tell you—I’ve seen way too many buckets get ruined because of lazy, last-minute storage moves. Yeah, you know the ones: left out in the rain, propped against a rusty fence, half-buried under a pile of gravel that no one’s gonna move for 6 months. That stuff adds up fast, and before you know it, you’re spending more on repairs or a whole new bucket than you would’ve if you’d just tucked it away right. Excavator Bucket

Today I’m breakin’ down exactly how to store an excavator bucket properly—no fancy, overpriced hacks, just stuff we actually use on our own yard and see work sites skip all the time. This isn’t just about “keeping it neat”; good storage saves you cash, cuts down on downtime, and makes your bucket last way longer than it would if you just tossed it aside. Let’s jump in.

First off, why does storage even matter? I get it—you’re busy. Job sites are chaotic, machines need to be running, and storing a bucket that’s 2-3 feet wide and weighs a ton feels like a hassle. But skip the right storage, and you’ll deal with:

Rust eating through the edges (that’s where your cutting teeth are, so if they’re rotted, you’re stuck pushing dirt instead of digging)
Bent or warved ears (those are the metal lugs that hook the bucket up to your excavator arm—bend one, and you can’t swap buckets mid-job without a welder)
Broken cutting edges or side plates (crunching on a loose rock pile because your bucket’s sitting on uneven ground = instant damage)
Even pest or rodent damage? Wait, yeah—those little buggers love nesting in the empty crevices of a bucket left outside, and their nests can clog up hydraulics or mess up the pins when you go to use it again.

All that stuff’s avoidable. I promise.

Now, let’s start with the basics: pre-storage prep. You can’t just drag a muddy bucket into a spot and call it good. I always tell our customers this is the most important step—skip it, and the storage part’s wasted. Here’s what you gotta do first:

Wash the hell outta that bucket
Dirt, mud, concrete residue, even leftover wet clay? That’s not harmless. That’s like leaving wet dog hair in your car seat—stinks, causes rust, and traps moisture. We use a pressure washer (3000 PSI minimum, no gentle stuff here) to blast every nook: the back of the bucket, the inside curve, around the pin holes, even the cutting teeth. If there’s caked-on concrete, let it soak in a degreaser for 10 minutes first, then use a stiff bristle brush to scrub it off. Don’t forget the pins and bushings—those tiny spaces hold so much muck, and it’ll make removing the bucket way harder next time you need it.
Inspect for damage, stat
Before you store it, take 2 minutes to walk around and check for cracks, bent ears, loose teeth, or worn side plates. Catch a small crack now, and you can weld it up for $50. Wait till you pull it out for a big dig, and that crack’ll turn into a split, costing you $500+ for a repair or a new edge. If you see a bent ear, don’t try to bend it back yourself—call a pro welder, that’s not a DIY job.
Protect the moving parts
The pins and bushings are the bucket’s backbone, right? If those rust up, you’ll never get the pin out when you need to swap buckets. After washing, spray the pins and all metal parts with a good anti-rust lubricant (we’ve used WD-40 Specialist, but any heavy-duty one works) and make sure it gets into the pin holes. For the cutting teeth, wrap a rag around them or spray a layer of grease to keep moisture off—they’re usually made of hard steel, but even that rusts if left damp.
Drain any gunk
Wait, excavator buckets aren’t just for digging, they hold water! If your bucket’s got a closed bottom (like a ditching bucket, not a open-tooth dig bucket), tip it upside down for a few hours to drain any leftover water from washing or rain. Stagnant water = rust, no exceptions. Even a tiny puddle in the bottom of the bucket can cause rust to start from the inside out, and you won’t even see it till it’s too late.

Okay, pre-storage done. Now where the hell are you gonna put it? This is where most folks mess up. Let’s talk about the two main options: on-site storage (for short-term, like a job that’s on a 3-week break) and off-site storage (for long-term, like winter layoff or a job that’s done for good).

Short-term storage (1 month or less)

If your crew’s taking a quick break, no need to haul it to a fancy warehouse—just pick the right spot on your job site. Here’s what to look for:

Flat, level ground: No hills, no ruts, no soft dirt that’ll sink when the bucket’s on it. If it sits at an angle, the weight’ll bend the side plates, and water’ll pool in the lowest part. We like using a concrete pad if we’ve got one, but if not, lay down a thick sheet of plywood or steel plates to keep the bucket off muddy ground.
Elevated from moisture: Don’t set it directly on dirt or grass. If you’re in a pinch, stack a few cinder blocks under the bucket’s two main lifting points (the ears, not the edges) to lift it up 2-3 inches. That keeps moisture from seeping up from the ground.
Out of the sun? Wait, no—wait, not directly, but covered? If you can, park it under a canopy or a portable garage to keep rain and snow off. But if you can’t, just make sure the bottom’s tilted a tiny bit (so water runs off, not pools) and spray the entire bucket with a quick anti-rust spray every 2 weeks. We’ve seen buckets left out for 3 months with no cover get way more rust than ones that were covered, even if they sat in the same spot.
Keep it away from other heavy stuff: Don’t park it next to a stack of rebar or a pile of gravel that could fall and dent the side. Also, keep it away from traffic—trucks and forklifts can knock into it, and if a tire runs over the pin, that’s a whole other repair.

Long-term storage (3 months or more, like winter or end-of-job)

This is the big one. I’ve seen buckets stored outside for a winter that came back looking like a rusted tin can, and ones stored properly that still look almost new. Here’s the step-by-step:

Use a dedicated storage spot: A closed warehouse, a rented container, even a covered portion of your yard with a concrete base is ideal. If you don’t have a warehouse, a 20ft shipping container works great—just make sure to drill a few small holes in the bottom for drainage so water doesn’t pool inside.
Elevate properly: This isn’t just for short-term. For long-term, use heavy-duty jack stands or steel blocks (not cinder blocks, they can crack under the weight) under the bucket’s lifting ears. Never set the bucket on its cutting edge—those teeth are hard but brittle, and the weight of the bucket can crack them over time.
Wrap it up: We recommend using a heavy-duty waterproof tarp (not the flimsy ones from the dollar store, they rip in a month). Drape it loosely over the bucket, but don’t pull it tight—you need a little airflow to prevent mold or moisture from getting trapped. If you’re in a super damp area, spray the entire bucket (inside and out) with a heavy-duty rust inhibitor before covering it.
Disconnect any accessories: If your bucket has a hydraulic thumb or any other attachments, remove them and store them separately in a dry spot. Hydraulic hoses are delicate, and leaving them attached and coiled tight can cause them to crack.
Check it once a month: Even if it’s covered, go take a peek. Make sure no water’s pooled on the tarp, no animals have chewed through it, and the lubricant’s still good. If you see any rust starting to form, wipe it off and re-spray with lubricant.

Wait, what about those weird edge cases? Like, storing multiple buckets? Or storing a bucket that’s already got some wear? Let’s cover those.

If you’ve got multiple buckets, don’t stack ’em. Stacking buckets puts uneven pressure on the lower one, which can bend the side plates or ears. If you have to stack, use steel beams between them to distribute the weight evenly, and never stack more than 2 high.
For a bucket that’s already got small rust spots: Before storing, sand the rust off, wipe it clean, and spray with anti-rust paint. That’ll keep those spots from spreading.
If you’re storing it in a cold climate, make sure to drain all water—even the tiny amounts that get into the pin holes. Water expands when it freezes, and that’ll crack the pins or bust the side plates. We learned this the hard way a few years back: a customer stored their bucket outside in Minnesota for the winter, didn’t drain the pin holes, and when it warmed up, the pins were split. Cost ’em $300 in replacements. Oops.

Now, let’s talk about what to avoid at all costs. These are the mistakes we see every single day:

Leaving it sitting on the cutting edge: We already mentioned this, but it bears repeating. That’s like leaving a knife blade flat on the ground—bent, dull, and damaged.
Not washing it before storing: Mud and concrete don’t “dry out” into nothingness. They trap moisture, cause rust, and can eat away at the metal over time.
Using flimsy tarps or no tarp at all: A $20 heavy tarp is way cheaper than a $500 bucket replacement. Don’t skimp here.
Stacking other stuff on top of the bucket: People love piling old rebar, lumber, or even old equipment on top of stored buckets. That dents the sides, bends the ears, and crushes the cutting teeth.
Forgetting the inside: Most folks only spray the outside, but the inside of the bucket is where all the moisture gets trapped. If you can, spray the inside too—even a quick coat of grease’ll help.

At the end of the day, proper storage is just about being lazy in the long run. If you take 30 minutes to prep and store your bucket right, you won’t have to spend hours fixing rust, bending, or broken parts when you go to use it next. That saves you downtime on the job, saves you money, and means you don’t have to rush to buy a new bucket last minute (we’ve all been there—emergency bucket orders cost way more than regular ones, trust me).
