If you run a landscaping business, operate a tree service company, or even manage a large residential property with extensive wooded areas, a wood chipper is one of the most workhorses in your fleet. I\u2019ve been selling wood chippers as a supplier for over 12 years now, and one question comes up more than any other: \u201cHow often do I really need to maintain my chipper to keep it running without breaking down mid-job?\u201d It\u2019s a fair question\u2014too little maintenance and you\u2019ll be stuck with a pile of branches and a machine that won\u2019t turn on when you need it. Too much and you\u2019re wasting time and money on tasks that don\u2019t need to happen that often. Let me break this down the way I explain it to every customer who walks through our door or messages us for advice. Wood Chippers<\/a><\/p>\n

<\/p>\n

First, let\u2019s get one thing straight: there\u2019s no one-size-fits-all answer. The maintenance schedule for your wood chipper depends on two big factors: how often you use it, and what kind of jobs you\u2019re using it for. A contractor who runs a chipper 8 hours a day, 5 days a week, chipping thick oak branches and whole small trees, is going to need a way more aggressive maintenance routine than a homeowner who pulls their chipper out once a month to chip fallen leaves and small twigs from their backyard. That said, there\u2019s a baseline schedule that works for most people, and I\u2019m going to walk through it step by step, including the stuff that\u2019s easy to skip until it\u2019s too late.<\/p>\n

Let\u2019s start with daily maintenance. This is the stuff you should do before you fire up the chipper every single time, even if it\u2019s just for a 10-minute job. I tell all new customers to build this into their pre-job checklist like they\u2019d check their phone or grab their safety glasses\u2014because skipping these small steps is the number one cause of preventable chipper breakdowns. First, inspect the feed hopper and the cutting area. You\u2019d be shocked how many people toss a nail, a piece of wire, or even a glass bottle into the hopper without thinking, and those items will dull your blades, jam your machine, or even cause serious damage. I once had a customer bring in a chipper that had stopped working mid-job because he\u2019d chipped a metal fence stake, and it had bent the flywheel so bad the whole unit needed a $800 repair. That\u2019s avoidable. Next, check the fuel and oil levels if your chipper is gas-powered. Low oil is the fastest way to destroy an engine, and running on empty fuel can lead to gunk building up in the carburetor over time. If you have a diesel chipper, add a fuel stabilizer if you\u2019re not going to use it for more than a week\u2014stale diesel is even worse for engines than stale gas. Also, give the wheels (if your chipper is mobile) a quick spin to make sure they\u2019re not flat or stuck on debris, and check the safety guards to make sure they\u2019re tight and not damaged. Those guards aren\u2019t there just to annoy you\u2014they\u2019re there to keep your hands from getting pulled into the hopper, so if a guard is loose, fix that before you start.<\/p>\n

Next, weekly maintenance for chippers that get regular use. If you\u2019re using your chipper more than once a week, do these tasks at the end of every week, even if it feels like extra work. First, clean out the chip chute and the undercarriage. Wood chips and sap build up fast, and if you leave them in the chute, they\u2019ll harden and block chips from coming out, which can cause the engine to overwork and burn out. I\u2019ve seen chippers where the chute was so clogged with old sap that it had to be cut off and replaced. Also, check the blades\u2014yes, even if they seemed sharp last week. A few small nicks from a rock or a nail will make your blades work harder, which uses more fuel and slows down your chipping. If you\u2019re not comfortable sharpening blades yourself, that\u2019s fine\u2014just inspect for nicks, and if you see any, mark that for a later sharpening. Also, check the bolts and fasteners all over the machine. Vibration from the engine and the blades will loosen bolts over time, and a loose bolt can cause a part to fall off mid-job. I always recommend keeping a small set of wrenches with your chipper so you can tighten any loose bolts on the spot. For electric chippers, check the power cord for frays or damage every week\u2014exposed wires are a fire hazard, so if you see any damage, don\u2019t use the chipper until you replace the cord.<\/p>\n

Now, the big one: monthly maintenance for most users, and bi-weekly for heavy use. This is the level where you\u2019re doing the tasks that prevent long-term wear and tear, and they should be scheduled every 30 days, or every 20 hours of use, whichever comes first. Let\u2019s start with blade care\u2014this is the most important part of chipper maintenance. How often you sharpen your blades depends on use: if you\u2019re chipping soft, small branches, you might go 50 hours between sharpening. If you\u2019re chipping thick, hardwood branches, you might need to sharpen every 20 hours. A good rule of thumb: if your chipper is making a loud, grinding noise instead of clean cuts, or if the chips are uneven and have rough edges, that\u2019s a sign the blades are dull and need sharpening. Dull blades don\u2019t just make the machine work harder\u2014they can cause jams because they\u2019re not cutting through wood cleanly, so the wood gets stuck in the hopper. If the blades are too worn to sharpen, you\u2019ll need to replace them. I always tell customers to keep a set of spare blades on hand because nothing kills a job faster than a dull blade in the middle of a tree removal.<\/p>\n

Next, check the belts and the drive system. The belt that runs the chipper\u2019s cutting mechanism is under a lot of tension, and it will stretch or crack over time. A loose or cracked belt will make the chipper slow down or stop working entirely. To check it, turn off the machine, unplug it (if electric) or disconnect the spark plug (if gas), then press the belt in the middle. If it moves more than half an inch, it\u2019s too loose and needs adjustment. If it has cracks or frays, it needs to be replaced. For heavy-use customers, check the belt every month\u2014for occasional use, every two months. Also, inspect the bearings that hold the blades and the flywheel. If you hear a grinding or squealing noise when the chipper is running, that\u2019s a sign the bearings are dry or worn. You can lubricate them with a high-temperature grease, but if they\u2019re worn out, they need to be replaced. Bad bearings can cause the blades to wobble, which damages the whole cutting system.<\/p>\n

Now, seasonal maintenance\u2014this is for people who use their chippers for part of the year, like landscapers who only work spring and summer, or homeowners who only chip in fall for leaf and branch cleanup. If you\u2019re storing your chipper for more than a month, you need to do a full pre-storage maintenance routine to keep it from rusting or developing issues while it\u2019s sitting. First, drain the fuel tank and run the engine until it stalls\u2014stale fuel will gum up the carburetor, which is a huge pain to fix. If you can\u2019t drain the tank, add a fuel stabilizer and run the engine for 10 minutes to circulate it through the system. Next, clean the entire chipper inside and out\u2014remove all wood chips, sap, and debris, and let it dry completely before storing. Wood and moisture will cause rust on the blades and the metal parts, so a good clean is key. Sharpen the blades before storing them, then lightly coat them with oil to prevent rust. Also, lubricate all the moving parts\u2014belts, bearings, wheels, hinges\u2014with grease or oil, depending on the part. If you\u2019re storing the chipper outside, cover it with a waterproof cover to keep rain and debris out. If you\u2019re storing it in a garage, make sure it\u2019s in a dry, level spot.<\/p>\n

Wait, let\u2019s address a common misconception I hear all the time: \u201cI don\u2019t use my chipper that much, so I don\u2019t need to maintain it.\u201d That\u2019s wrong. Even a chipper that sits in a garage for a year will develop issues. Rust, stale fuel, and seized bearings are all problems that come from lack of use, not just lack of use. I had a customer who bought a chipper for a one-time backyard project, stored it for three years, and when he tried to use it, the engine was seized from rust, and the blades were so dull and corroded they had to be replaced. He ended up paying more to repair the stored chipper than he would have to just maintain it regularly.<\/p>\n

Another thing to consider: safety inspections. Every time you do maintenance, make it a point to check all the safety features. This includes the emergency stop button, which should work every time you press it to shut down the machine immediately. Check the feed hopper\u2019s safety interlock\u2014if the hopper is open, the machine shouldn\u2019t start. If any of these features are broken, fix them right away. Don\u2019t run a chipper with a broken safety feature, even if it\u2019s a quick job. It\u2019s not worth the risk.<\/p>\n

Now, let\u2019s talk about signs that your chipper is overdue for maintenance, no matter the schedule. If you notice any of these, don\u2019t ignore them\u2014fix them as soon as possible, before a small issue becomes a big, expensive repair. First, unusual noises: grinding, squealing, or rattling that wasn\u2019t there before. That\u2019s a sign something is loose, dull, or worn. Second, poor performance: the chipper is taking longer to chip wood than usual, or it\u2019s jamming often. Third, leaks: oil leaks or fuel leaks are never a good sign, and they can be a fire hazard. Fourth, visible damage: dents in the hopper, bent blades, or cracked parts. Even a small dent in the hopper can cause wood to catch, leading to jams.<\/p>\n

I get it\u2014maintaining a wood chipper can feel like a chore, especially when you\u2019re busy with jobs. But I always tell customers that the cost of maintenance is way less than the cost of repairing a broken chipper mid-job, or having to buy a new one. A good chipper is an investment, and taking care of it will make it last for years. For example, a well-maintained wood chipper from our inventory will easily last 10 to 15 years, while a neglected one might need to be replaced in 3 to 5 years. That\u2019s a huge difference in cost over time.<\/p>\n
