We needed a second blower and having had excellent service out of our first SR6400L we bought another. Incredible power and though a little heavy, they are very good at their job. We have a couple of acres, all of it wooded. We blow the sides of the home and the front. More leaves than you can imagine. Yet yesterday, the DW and I got the job done in about 3 hours. Amazing. I only have one small suggestion for Schroder.... The thumb screws that hold the top of the air cleaner on are the weak point. They work loose, and if you tighten them up snuggly, you end up stripping the threads. I finally found a long machine screw with a rubber spacer and a nut, and fixed the older machine, but already the two thumb screws on the new one are coming loose. Don't let such a minor item dim the shine on a terrific piece of engineering that this model SR-6400L is. Put out a fix for this. ;-) We love these blowers, and the new one is two pounds lighter, meaning the wife uses it without a single complaint. Very nice piece of equipment........fix the thumb screws.

My handheld blower's engine seized due to a failed carburetor mount that let air leak past the carburetor and catastrophically lean out the engine. So, new blower since parts cost more than a new one. Note UPDATE below... I gave this Schröder blower five stars based on a performance/price metric and build quality, but there are some live-withs to consider. See "Cons." --- See EDIT -- I have three acres of landscaped property out of five acres with lots of oaks having smallish leaves, augmented with redbuds, maples, and others with large leaves. Its an ongoing battle with the oaks all year, others in the fall. The handheld just didn't do it, but I made it work for about 10 years. I never could blow wet or damp leaves..... This Schröder seemed to offer the performance of the usual suspects at half the cost. Reviews seem good. I bought it. PROS: - This Blower Moves Leaves! After being without a blower for about ten Fall days, I first used the Schröder the day after a heavy rain that added a lot of leaves to the existing ten-day normal Fall accumulation. I spent four hours, three tanks of gas, and moved all the wet leaves and large acorns without a worry. Amazing. The blower's operational performance is exceptional. Wow. - Starts on the second pull when cold, every time. - Reasonable Weight. At just over 20 lbs, its lighter than some in its class. Makes for a nice workout addition to your 10,000 steps around the yard cleaning up. Plus, you get those "magic fingers" vibration through your back as you traverse the yard. What's not to love? - Well Built. The Schröder seems tight, well constructed and solid. The blower nozzles have set screws to hold them together and include both round and flat blower nozzles. The air filter has both a foam pre-filter and a proper pleated paper secondary filter. All the assemblies have the look and feel of fit-for-purpose and sturdiness. Some thoughtful engineering went into the base blower package. - Comfortable. The thickly padded shoulder straps, and waist and chest straps keep the blower solidly against your body. The pistol grip throttle position is adjustable along the length of the blower nozzle. CONS: - Throttle Trigger is too Stiff. I had to keep switching fingers between index and middle. The throttle return spring is too stiff. The trigger itself is wide enough, but trigger pressure is just too much after a while and your finger tells you it has had enough. Yes, I was out there about four hours, but your trigger finger shouldn't be the limiting factor. I commented to myself about this stiffness as I was pre-assembling the unit - and it proved out in application. I will take the throttle assembly apart and see if I can cut down a spring somehow, or identify the source of the stiffness and relieve it. We'll see. - Single Position Throttle Lock. Rather than a friction-based throttle lock that allows holding any throttle position, this unit has a button that holds the throttle at about 3/4. That may be fine for most uses, but not for heavy, wet leaves when you need all the power you can get. - Recoil Starter is Very Hard to Pull. No, I'm not a wimp. The recoil spool is only about 2.5 inch in diameter and the engine must have about 13:1 compression ;) Bad combination. There is no place to put your foot on the blower to hold it while pulling the cord. So, set blower on the ground, put left hand on the rubber neck above the carburetor, pull the cord, get only about one compression stroke as the blower jerks and slides. Fortunately, it starts right up. My wife is pleased that she'll never be able to start it herself. CONCLUSION: I'm keeping it. I love the power, the weight, the magic fingers. I'll figure out something with the throttle, live with the recoil starter, and put the about $300 additional that a usual suspect blower would cost toward another project. As with all power tools, wear ear protection. Note, if you need to adjust the carburetor for altitude, you will need the larger "ACircle" carburetor adjustment tool. Never mind if you don't know what that means. UPDATE 11/21/2020: I took the pistol grip throttle assembly apart - three screws and an allen bolt - to see what can be done about the stiff throttle. A lot, actually. Both the trigger and the throttle interlock have circular springs; both are easily removed. Since the carburetor itself has a fully functional return spring, the one on the handle is a backup, I suppose. The throttle pressure is SO MUCH BETTER without that spring on the trigger. Then, removing the spring on the interlock keeps it depressed so you don't have to keep a firm grip on the handle and can depress the throttle without actively squeezing the interlock. I hid both springs in the handle up near the on-off switch in case, well just in case. See the two pictures of the opened up throttle assembly - one with the springs in place, the other with them removed. Also, regarding starting the unit. Placing a firmly weighted left hand on top of the air filter housing, or on top of the exhaust housing next to the spark plug improves the recoil pull experience. OK. Another tank and a half of fuel this afternoon and I'm a happy camper. I'd buy this again, but hope I never need to do so. Update: 3 January, 2024 Three years in and the blower continues to impress me. The only issue is a broken plastic waist belt clip. I replaced it. Update: 30 October, 2025 Five years in and our local gasoline destroyed the fuel lines. Fortunately, I had some fuel line available and was back in business shortly. Also, the starter pull cord mostly frayed at the handle. A short time later I'd shortened the cord by a couple of inches and tied a new knot. Note, that the blower came with a second, replacement, pull cord assembly. Fortunately, it still sits in a drawer in my shop. I'm back in business with my wonderful blower that competes nicely with those twice the price.

We have a one acre property that is pretty heavily wooded... I normally blow the leaves into the back woods during late November... I was preparing my Ryobi blower for this year when once again, I could not get it to turn-over... I've had the blower for a few years... Have always used ethanol treatment in the gasoline... I've replaced the carburetor once, and the pull start assembly twice... The engine has always been hard to start, and typically would start to bog down after a short period of operating... This year I was faced with another carburetor replacement and pull start assembly... I had enough... I went on line and decided to purchase the Schroder SR-6400L, based on the reviews... About the same price point as the Ryobi... The blower arrived a day early... It was easy to assemble... It started on the second pull out of the box, and subsequently on the first pull thereafter... The trigger pressure was easy... The pull start a little stiff, but okay once you knew what to expect... The blower runs great, and the blowing capacity makes quick work of getting the leaves where you want them... The gas tank is pretty substantial, but fuel consumption is consistent with the work that this unit delivers... This is a well engineered unit... I wish that I had purchased this blower a long time ago...

This is my 4th year of ownership, very happy with this blower, reliable and always starts without issue. Currently having an issue with the fuel line connection into the fuel tank but it is probably an easy fix, if not, there is a replacement kit that I'll order.
