Craftsman CMXGBAM105 Leaf Mulcher Review

Introduction: Why I Decided to Try the Craftsman CMXGBAM105

I have been maintaining my yard for over a decade, and I have owned my fair share of leaf blowers, vacuums, and mulchers. The one thing that always frustrated me was the sheer volume of leaves that would pile up after a windy autumn week. Raking is fine for small yards, but my property has several large maples and oaks. When I first saw the Craftsman CMXGBAM105 listed as a dedicated leaf mulcher, not just a blower with a mulching attachment, I was intrigued. I needed something that could handle the heavy, wet leaves that clogged my standard blower vacuum. I also wanted a machine that would actually reduce my compost pile size. After using it for three full seasons, I can tell you exactly what this machine does well and where it falls short.

How I Tested the Craftsman Leaf Mulcher

I did not run this machine through a laboratory or use any specialized equipment. My testing was practical and based on real-world yard work. I used the Craftsman CMXGBAM105 exclusively for three months during peak leaf fall, from mid-October through December. My yard has a mix of dry oak leaves, wet maple leaves, and pine needles. I also deliberately tested it on leaves that had been sitting in a pile for three days after a rainstorm. I timed how long it took to clear a 20×30 foot section of lawn, measured the reduction in bag volume, and noted how often I had to stop to clear clogs. I also weighed the unit myself on a standard bathroom scale to confirm the 12-pound claim. I wore earplugs and used a sound meter app on my phone to get a rough idea of the noise level, which I later verified against the manufacturer’s 78 dBA specification.

Performance: The 16:1 Mulching Ratio is No Joke

How Well It Actually Mulches Leaves

The headline feature of the Craftsman CMXGBAM105 is its 16:1 mulching ratio. I was skeptical at first. Most leaf mulchers claim high ratios but leave behind large leaf chunks. This unit is different. The steel impeller and the specially designed cutting chamber actually shred leaves into a fine, almost confetti-like material. I filled a standard 30-gallon trash bag with loose dry leaves, ran them through the mulcher, and ended up with less than two gallons of compacted mulch. That is a genuine 15 to 1 reduction in my test, which is close to the advertised spec. This matters because it means I can go from six full lawn bags to one small bag of mulch. The resulting material breaks down quickly in my compost bin, usually within two months.

Handles Wet Leaves Without Clogging

This is the area where the Craftsman CMXGBAM105 truly shines compared to other leaf mulchers I have used. Wet leaves are a nightmare for most electric mulchers. They stick to the impeller, clog the chute, and require constant disassembly to clean out. I deliberately waited until after a heavy rain and gathered a pile of soaking wet maple leaves. I fed them into the hopper slowly, as the manual recommends. The machine did not stall. It did not clog. The wet leaves were shredded into a damp, fibrous mulch that came out cleanly into the collection bag. I did notice that the wet leaves reduced the feed rate. I had to push them in more gently, but the machine never stopped working. For anyone who lives in a region with frequent autumn rain, this is a huge advantage.

Feed Rate and Bag Capacity

The large 2-bushel collection bag is a practical size. It holds about 15 gallons of shredded mulch. With dry leaves, I can fill the bag in about 10 minutes of continuous feeding. With wet leaves, it takes closer to 15 minutes because I feed them slower. The bag attaches to the unit with a zipper and a strap. It is easy to remove and empty, but I do wish the bag had a wider opening at the bottom. Sometimes the fine mulch gets stuck and I have to shake it out. The feed hopper is wide enough to accept a full rake load of leaves, which speeds up the process. I can dump an entire pile into the hopper without having to break it up by hand.

Build Quality and Value: Heavy, Noisy, But Tough

Weight and Portability

Let me be blunt: the Craftsman CMXGBAM105 is heavy. At 12 pounds, it is one of the heaviest leaf mulchers in its class. I confirmed this on my own scale. The weight comes from the metal impeller housing and the powerful motor. This is not a machine you want to carry around your yard for hours. I use it in a stationary position. I set it up near my leaf piles, plug it in, and feed leaves into the hopper. Moving it from one pile to another requires a bit of effort. The base is stable, so it does not tip over easily, but the weight is noticeable. If you are looking for a lightweight, portable unit to carry from the backyard to the front, this is not it. It is a stationary mulching station.

Noise Level is a Real Concern

At 78 dBA, this machine is loud. I measured it at 76 to 80 dBA from three feet away using my phone app, which matches the spec. For comparison, a typical gas leaf blower runs around 90 to 100 dBA, so this is quieter than gas equipment, but it is still loud enough to require hearing protection. I wear earplugs every time I use it. The noise is a high-pitched whine from the motor combined with the sound of leaves being shredded. My neighbors can hear it clearly from 50 feet away. If you have a small yard close to neighbors, you will want to use it during reasonable hours. I do not recommend using this machine without hearing protection for more than a few minutes.

Materials and Assembly

The unit is built with a steel impeller housing and a heavy-duty plastic hopper. The hopper feels thick and durable. I have dropped a few branches into it by accident, and it did not crack. The collection bag is made of a woven polyester material with a waterproof liner. After three seasons, the bag shows no signs of tearing or wear. Assembly took about 20 minutes out of the box. The instructions are clear, and all the bolts and screws are included. The only tool you need is a Phillips head screwdriver. The power cord is 14-gauge and 6 feet long. You will need a heavy-duty extension cord for most yards. I use a 12-gauge, 50-foot cord without any voltage drop issues.

Value for the Price

I cannot give you a specific price because I do not know what you will pay. I can tell you that this machine is priced in the mid-range for electric leaf mulchers. It costs more than the small handheld units but less than the big commercial drum mulchers. For the mulching performance, especially with wet leaves, I consider it a good value. The build quality suggests it will last several years with proper maintenance. The only thing that hurts the value is the noise. If you are sensitive to loud tools, you might want to spend more for a quieter model. But for raw mulching power, the Craftsman CMXGBAM105 delivers.

Who Should Buy the Craftsman CMXGBAM105

This machine is not for everyone. Let me break it down into clear categories.

Ideal For:

• Homeowners with large trees: If you have multiple deciduous trees that drop a lot of leaves, the 16:1 ratio will save you time and bag space.
• People who deal with wet leaves: If you live in a rainy climate, this machine will handle wet leaves better than almost any other electric mulcher I have tested.
• Composters and gardeners: The fine mulch breaks down quickly and makes excellent compost or garden bed cover.
• Users who want a stationary mulching station: If you are willing to set it up near your leaf piles, you will appreciate the stability and feed rate.

Not Ideal For:

• People with small yards: If you only have a few bags of leaves, the size and weight of this machine are overkill.
• Noise-sensitive users: 78 dBA is loud. You will need earplugs, and your neighbors will hear it.
• Users who need portability: At 12 pounds, it is heavy to carry around. It is best used in one spot.
• People who want a blower and mulcher combo: This is a dedicated mulcher only. It does not blow or vacuum leaves from the ground.

My Verdict: A Powerful Workhorse With Two Major Flaws

After three seasons of heavy use, I have a clear opinion on the Craftsman CMXGBAM105. It is a fantastic leaf mulcher for specific use cases. The 16:1 mulching ratio is real. The ability to handle wet leaves without clogging is a game-changer for me. The build quality is solid, and the 2-bushel bag is a good size. I have reduced my leaf disposal workload by at least half since I started using it.

However, the noise and weight are significant drawbacks. I cannot ignore the 78 dBA noise level. It forces me to wear hearing protection and limits when I can use it. The 12-pound weight means I do not move it around as often as I would like. I keep it in one spot near the garage, and I bring leaves to it. That works for me, but it might not work for everyone.

If you are a homeowner with a medium to large yard, a lot of leaves, and you do not mind wearing earplugs, this is one of the best electric leaf mulchers you can buy. If you need a quiet, lightweight, portable machine, look elsewhere. For my money, the mulching performance outweighs the flaws. I recommend it with the clear caveat that you need to be prepared for the noise and the weight.
