If you\u2019ve ever been in the concrete finishing industry, you know a power trowel isn\u2019t just another piece of equipment\u2014it\u2019s your workhorse. For our team here, that means we don\u2019t just sell power trowels; we help customers keep those tools running year after year, even when they\u2019re not in use for long stretches. Storing a power trowel correctly over an extended period isn\u2019t just about keeping it clean\u2014it\u2019s about protecting the engine, the rotating blades, and every small part that makes the machine work. Skip the right steps, and you could be looking at a hard start, corroded parts, or even a broken tool come spring or whenever you pull it back out. Power Trowel<\/a><\/p>\n

<\/p>\n

I\u2019ve seen the mistakes. Last year, a customer brought a trowel back to our shop that\u2019d been stored in a damp garage for six months. The engine was seized solid, the blade assembly had rusted so bad the bolts wouldn\u2019t turn, and the fuel lines were clogged with stale gas. It cost him more to fix than he\u2019d paid for the trowel used. That\u2019s why I decided to put together this step-by-step guide, drawn from years of working with power trowels\u2014both selling them and helping customers keep them in top shape. If you follow these steps, your trowel will be ready to go when you need it, no last-minute headaches.<\/p>\n

First, let\u2019s start with the prep work before you even set the machine in storage. This is the most critical part, and it\u2019s where most people cut corners. The first thing to do is drain or treat the fuel system. Old, stale gas is the number one cause of small engine problems, and power trowel engines are no exception. Gas breaks down in as little as 30 days, leaving a gummy residue that clogs carburetors, fuel lines, and fuel pumps. If your trowel has a carbureted engine, which most standard models do, you have two options: drain the fuel completely, or add a fuel stabilizer. Draining is more reliable for long-term storage. To do that, run the engine until it runs out of gas on its own\u2014this clears the carburetor and lines entirely. If draining isn\u2019t feasible, use a fuel stabilizer formulated for small engines (avoid car stabilizers, they\u2019re not the same) and run the engine for 5 to 10 minutes after adding it, so the treated gas circulates through the entire fuel system. Don\u2019t forget to disconnect the spark plug wire first, just for safety.<\/p>\n

Next, clean the trowel thoroughly. Concrete dust, wet mortar, and cement mix don\u2019t just sit on the surface\u2014they seep into joints, around blade arms, and into the engine\u2019s cooling fins. Over time, that debris will absorb moisture, leading to rust, and grind against moving parts, causing wear. Grab a pressure washer (set to low pressure, around 1500 PSI\u2014high pressure can damage seals and bearings) or a stiff bristle brush, and scrub every inch: the blade assembly, the handles, the engine casing, and the bottom frame. For caked-on concrete, use a mild concrete degreaser, but make sure to rinse it off completely\u2014leftover chemicals can damage paint and seals. Once it\u2019s clean, let it dry completely. A damp trowel in storage is a ticking time bomb for rust, so leave it in a dry, well-ventilated area for 24 hours before moving it.<\/p>\n

Now, move to the mechanical parts. The rotating blade assembly is especially vulnerable. Remove the blades (always use gloves\u2014they\u2019re sharp) and wipe down the blade arms, bolts, and the hub with a light oil, like 30-weight non-detergent oil or a specialty machine lubricant. Don\u2019t use heavy grease here, it will attract dust. Make sure to oil the blade bolts and the pivot points, too\u2014these are spots that often get missed. For the engine, not just the fuel system, change the oil before storage. Old oil holds moisture and acidic byproducts from use, so draining it and adding fresh oil prevents internal engine corrosion. Check the air filter, too: if it\u2019s dirty, replace it or clean it (depending on if it\u2019s paper or foam). A dirty air filter will let dust get into the engine while it\u2019s stored, which causes wear when you start it up.<\/p>\n

Then, address electrical components and batteries, if your trowel has an electric start. If it\u2019s a gas model with a recoil start, just make sure the spark plug is clean\u2014remove it, brush away any carbon buildup, and leave a small amount of anti-seize compound on the threads before putting it back in. For electric start models, take out the battery. Don\u2019t leave a battery on the machine during storage\u2014even a fully charged one will lose power over time, and it can leak acid, which damages the frame and engine. Clean the battery terminals with a wire brush, apply a light coat of terminal protector or petroleum jelly, and store the battery in a cool, dry place (not attached to concrete floors, which can draw moisture). Check it every month or so, and top it off with distilled water if it\u2019s a flooded lead-acid model.<\/p>\n

Now, choosing the right storage location is almost as important as the steps above. A lot of people think a shed or a garage is enough, but if it\u2019s damp, that\u2019s a problem. Concrete floors, in particular, hold moisture\u2014so if you put your trowel directly on a concrete slab, the bottom frame will rust from the bottom up. Elevate it on wooden pallets or cinder blocks, at least 6 inches off the floor. The ideal storage spot is a climate-controlled space, like a heated shop or a dry warehouse, with temperatures between 50 and 70 degrees Fahrenheit. If you have to store it outside, cover it with a heavy-duty waterproof cover, but make sure it\u2019s not airtight\u2014condensation can get trapped inside and cause rust. Avoid plastic tarps, they don\u2019t breathe. A breathable nylon or polypropylene cover works best.<\/p>\n

Once it\u2019s in storage, there are a few monthly checks that take 5 minutes and will save you big issues later. First, if it has a battery, check its charge level\u2014most batteries will need a top-up or a trickle charge every 30 to 60 days. For the blade assembly, rotate the blades by hand a quarter turn every month\u2014this keeps the bearings from seizing up, a common problem when parts sit in one position for too long. If you\u2019re storing it for more than six months, pull the blades again and re-oil them, just to be safe.<\/p>\n

When you\u2019re ready to pull your trowel out of storage, don\u2019t just fire it up right away. Do a pre-use check: first, drain any old fuel that might have accumulated if you didn\u2019t treat or drain it before storage. Refill with fresh gasoline, and check the oil level. Reconnect the spark plug wire, then pull the recoil starter a few times (or turn the key, if it\u2019s electric) without starting the engine, to prime it. Once it starts, let it idle for 5 to 10 minutes, and check for any unusual noises or leaks. If the blades don\u2019t move smoothly, they might need a little more oil\u2014just don\u2019t overdo it.<\/p>\n
