If you rely on a skid steer loader to keep your jobs on track—whether you’re excavating a small backyard, clearing a construction site, or landscaping a residential property—you already know these machines are workhorses. But what separates a loader that runs for 10,000 hours without major breakdowns from one that needs constant repairs? It’s not just how hard you work it; it’s how well you maintain it. As a supplier of skid steer loaders, I’ve seen firsthand that proper maintenance cuts downtime by up to 60% (yes, that’s a number we pull from our thousands of client records over the last 15 years) and extends a loader’s lifespan by 50% or more. Skipping even small, routine checks can turn a $50 oil change into a $5,000 hydraulic repair, or worse, a jobsite shutdown that costs you money and clients. Skid Steer Loader
I’m not here to sell you a brand-new loader today—though if you do need one, we’d love to talk—but to share the hands-on, practical maintenance habits we teach every customer who buys from us. These aren’t generic tips from a manual; they’re the lessons we’ve learned from field technicians, hardworking operators, and the few clients who ignored our advice and paid the price. Let’s break this down into simple, actionable steps you can do every day, every month, and every year to keep your skid steer running strong.
First, let’s start with daily checks. These are the 10 minutes you spend before you even fire up the engine, and they’re non-negotiable. I’ve had operators show up at 7 a.m. to a jobsite, turn the key, and immediately get a “low hydraulic pressure” warning only to find a loose hose clamp that could have been spotted in 60 seconds. Here’s what to cover:
Fluid levels are your first stop, and I don’t mean just the engine oil—though that’s important. Skid steers have four key fluids that need daily checks: engine oil, hydraulic fluid, coolant, and fuel. Engine oil should be checked when the engine is warm (not running, turned off for five minutes to let oil settle) to avoid inaccurate readings. Wipe the dipstick, reinsert it fully, and pull it again; the level should be between the “min” and “max” lines. If it’s low, add the correct weight of oil (check your operator’s manual—most of our loaders use 10W-30 in moderate climates) and top it off slowly; overfilling causes leaks and engine damage, too.
Hydraulic fluid is even more critical because it powers all the attachments—buckets, augers, brush cutters, whatever you’re using. Never check hydraulic fluid when the machine is hot, and never let the level drop below the “min” line. Low hydraulic fluid leads to air bubbles in the lines, which cause spongy controls, reduced power, and even pump failure. And for the love of your loader, don’t use old, dirty hydraulic fluid. We see operators top off with fluid they drained from a job three months prior, and that’s a fast track to clogged filters and worn components.
Coolant is often overlooked, especially in warmer months, but it prevents overheating and corrosion in the engine. Check the reservoir (not the radiator itself—you can burn yourself) when the engine is cold. If it’s low, use a 50/50 mix of coolant and distilled water, not straight coolant or tap water. Tap water has minerals that build up in the cooling system, leading to blockages and overheating. Fuel: Make sure you’re not running on fumes. Water and sediment collect at the bottom of fuel tanks, and running low means you’ll pull that gunk into your fuel filter, causing injection problems.
Next, daily visual inspections. Walk around the loader, and I mean slow enough to spot small issues. Check the tires (or tracks, if you have a track loader) for cuts, bulges, or debris stuck in the tread. For track loaders, even a small rock wedged between the track and sprocket can cause excessive wear over time, or even derail the track entirely mid-job. Look at hoses: hydraulic hoses, fuel lines, radiator hoses. Any crack, bulge, or leak is a problem. Even a small hydraulic leak that leaves a wet spot on the ground today can turn into a ruptured hose tomorrow, stranding you on a jobsite. Also, check the bucket and attachment for loose bolts—you don’t want your bucket falling off while you’re lifting a 1,000-pound boulder. Oh, and don’t forget the controls: make sure the joysticks or levers move smoothly, no sticking or delayed response.
After you finish your daily checks, it’s good practice to run the engine for two minutes and test all functions before you start working. That’s when you’ll spot that sticky hydraulic valve or a squeaking wheel bearing, before it becomes a bigger issue.
Now, monthly maintenance. This is the stuff that takes an hour or two, but prevents problems that come up every few hundred hours. Let’s start with filters. Your loader has several filters—oil, hydraulic, fuel, air—and they need to be changed regularly, not just when the manual says. Engine oil filters usually go every 50 hours, hydraulic filters every 200, and fuel filters every 100. Air filters are especially important because a dirty air filter restricts airflow to the engine, reducing power and increasing fuel consumption. I’ve seen operators run a paper air filter until it’s caked in dust and leaves, and that cuts engine power by 15%—that’s like working with half the machine you paid for. To check the air filter, remove the outer cover and tap it gently on a hard surface—if dust still comes out, it’s time to replace it. If you work in extremely dusty conditions, you might need to change it twice as often, no exceptions.
Next, lubrication. Skid steers have dozens of grease points—pivot points for the bucket, lift arms, attachment mounts, even the steering joints. Every time you change the oil, you should grease these points. Use the correct type of grease (we recommend lithium-based grease for most of our loaders) and don’t over-grease it—too much grease can push dirt into seals, causing more wear. Wipe the grease gun nozzle before connecting it to avoid introducing dirt into the fitting, too. I remember one customer who skipped greasing his pivot points for six months; when he finally brought his loader in, the lift arms were so stiff he could barely move them, and we had to replace the pins and bushings for $2,000. A $5 tube of grease would have saved that bill.
Also, monthly, clean the radiator and condenser. Dust, mud, and grass clippings build up on these, blocking airflow and causing the engine to overheat. Use a low-pressure air compressor (high pressure can bend the fins) or a garden hose to rinse them out, working from the inside out to push debris through. If you let that buildup sit, the engine will run hotter than it should, shortening its lifespan.
Now, annual maintenance. This is the deep dive, the stuff that should be done by a certified technician at least once a year, or every 1,000 hours, whichever comes first. If you’re new to skid steer maintenance, don’t try to do this alone—hydraulic systems are pressurized, and messing with them can cause serious injury. Find a technician who works on skid steers regularly (we have a network of certified service partners across the country, if you need a referral) to handle these steps.
First, a full fluid flush and replacement. Every two years, or 2,000 hours, you should flush the hydraulic system completely, not just top it off. Old hydraulic fluid breaks down, loses its lubricating properties, and can have contaminants that damage the pump and valves. A flush costs a fraction of replacing a hydraulic pump, which can run $7,000 to $10,000. Also, flush the cooling system—drain the old coolant, flush the block and radiator to remove corrosion, and refill with fresh 50/50 mix.
Then, a thorough inspection of the undercarriage. For track loaders, this means checking the tracks for wear, adjusting track tension (too loose and they derail, too tight and they wear out sprockets and idlers), and inspecting rollers and idlers for damage. For wheel loaders, check wheel hubs for play, replace wheel bearings if they’re loose, and inspect brake components—brakes are easy to overlook, but skid steers move quickly on tight jobsites, and bad brakes can cause accidents.
Also, annual electrical system check. Corrosion on battery terminals, loose wires, or worn alternator belts can cause starting problems or even electrical fires. Clean the battery terminals with a baking soda solution to remove corrosion, tighten any loose connections, and check the alternator output to make sure it’s charging the battery properly. If you notice dim lights or slow cranking, don’t ignore it—replace the battery before it dies mid-job.
Now, a few extra tips from the field that we’ve learned from customers. First, don’t overwork your loader. It’s easy to push a skid steer beyond its rated capacity, whether that’s lifting too much weight, digging too deep, or running it at full throttle for hours on end. Every loader has a rated operating capacity (ROC)—stick to that, even if you think you can get away with more. Overloading causes stress on the lift arms, hydraulic system, and engine, leading to premature failure. Second, store your loader properly when it’s not in use. If you leave it outside, cover it with a heavy-duty tarp to protect it from rain, snow, and UV rays. Run the engine for 10 minutes once a week during long storage to keep fluids circulating, and fill the fuel tank to prevent condensation inside the tank, which causes rust. Third, keep a maintenance log. Write down every oil change, filter replacement, grease job, and repair you do. This helps you stay on schedule, and if you decide to sell the loader later, a detailed log increases its resale value by a significant amount.
I know what some of you are thinking: “I don’t have time for all this maintenance. I just need to run my machine.” Trust me, I get it. When you’re on a tight job, every minute counts, and pulling the loader off to change an oil filter feels like a waste. But let’s do the math: a 15-minute oil change every 50 hours adds up to about two hours a month. Compare that to a $5,000 repair that takes two days to fix, costing you $10,000 in lost jobs. It’s not a waste—it’s an investment.
At the end of the day, a skid steer loader is only as good as the care you give it.
