Schröder Backpack Leaf Blower - Backpack Blower - Gas Leaf Blower - SR-6400L - 3.7 HP Engine

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.

**Review Update** Been over a year now. Blower has bwen a real work horse. Love everything about it. Especially the well padded harness. A couple of improvements would be appreciated. 1.. mold into the frame a foot brace to make starting easier. 2.. add a cruise control to the blower speed control. Basically be able to loc the blower at a preset speed.. would help with trigger fatigue. ** Blower arrived the other day. Well packed and additional protective cardboard lining. Very easy to assemble. Only took a few minutes and a philly's screwdriver. FIRST IMPRESSIONS: Unit is well made and well designed. One thing I did not see in any of the reviews was that the unit comes with 2 blower tips. A faired tip and a round tip. Wondered, because I saw both pictured but not described. The next thing I noticed was unlike other backpack blowers I have had, this one had threaded screws that hold the sections from coming loose. They still use the twist lock sections but with a screw, not into plastic but metal on metal. The unit is powerful. Much more powerful than my old backpack blower or my hand-held blower. With the flared tip, it can move a lots of dry leafs, wet leafs, leaf mold, gravel, blows small sticks and dead wood easily and clears a wide path. For the money it's a great blower and a good value. Be aware that these ship from BC Canada and had to go through customs which added a day or two. Now for the things you should also know. I assume this motor does not have compression release. Takes some strength and a good stable area to start. I hold the backpack at the top and brace my boot on the lower frame. Takes a couple of pulls normally. Not nearly as easy as other 2 strokes I have had. My 2 cycle snowblower took less effort. Vibration: Evidently this blower also has no Vibration dampening. Not too bad and you sort of get used to it after a while. NO cruise control. Now this may seem like no big deal BUT… Engine speed is controlled by the trigger on the hand grip. No way to keep the motor at full throttle without a finger on the trigger. When you spend hours blowing leafs it's nice to vary hand positions. Trust me, you will be looking for a rubber band or two if you have a large area to clear. I would say, a tank full of mixed gas will get you about 2 hours of run time.. not bad for the power this generates. Overall, I am very impressed with the quality and utility of the blower. Hope the manufacturer reads this post. With a few low cost modifications this unit could be world class. Maybe that's what you get with their $700+ model.. don't know. Reading the description the models sounded basically the same.

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...

It's a pretty good blower and it runs very good.Gas leaked under gas cap for some reason duck tape inside the cap helps for now will try a new washer later. Overall I'm happy with it. It cleans and starts pretty quickly throw out plenty of air with great strength and the harness straps are okay also.

Mine was placed into service 11/12/2025. I’ve used it several times making huge piles of leaves so that I can use my mulcher to shred them for compost. This blower has plenty of power. I've had no problem starting it. The only assembly is with the tube, it took me about 15 minutes and then I was up and running. This machine is advertised as light weight but I would say that depends on the user. For me it feels heavy but manageable. I doubt if my petite wife could use it. Too heavy for her. I do concur with other reviews that it would be nice to have a place where you could anchor your foot while starting. I can get a toe on the frame and then lightly place my other hand on the air filter while pull-starting. A tank of gas will last about an hour of non-stop use which I’m ready to take a break then anyway. Overall, I like it and I’m glad I have it.

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.

Honestly I was a little wary of how the blower would be. I read a few reviews about the trigger, CFM not being accurate, questionable adjustments on the car wrat or, replacement parts not accessible, ect. All of them have either been exaggerated or the company has fixed everything going forward. Pros: you can’t beat the price. I was looking at Husqvana 150 and Echo 580t and honestly this blower is clearly more powerful not to mentioned cheaper. The build is solid and you can tell where the company cut corners to provide the price point of ~$325 but it’s clearly intentional and I don’t mind it one bit. It’s easy to put together, took >10mins. The back cushion is just a solid piece of foam, not fabric like Husq or rubber like echo, but honestly plenty comfortable. The straps look like a cheap parachute backpack but they work fine. The vibrations are somewhat poorly managed but honestly I don’t notice it even at full throttle. The throttle is comfortable and adjustable to lock in the speed. The pulling to start is weird at first but very simple once you get the hang of it. Starts right up 2nd pull no problem. The carburetor absolutely was perfect right out of the box but even if you did need to adjust it it’s a simple YouTube video to figure out how to adjust airflow. And if for some reason I needed a spare part their website has every possible part to replace in stock and listed for sale. Overall The company is smart, they provide the best price point and focus on what’s most important for your average home owner. Most commercial guys are looking at name brands and need to wear this backpack for hours long every day. That’s not most homeowners and definitely not me. It’s legit the best blower I’ve had the chance to use and couldn’t believe it was Under $400 it honestly should be closer to $500+ in regards to power and quality. Definitely give this blower a try, it’s totally worth it and You won’t regrets it!

Have had this blower for 3 years now and I'm very pleased powerful and reliable.

It is a powerful and reliable machine. After 5 years, it can still start at first pull, just love it.

Easy to assemble. Easy to start. Doesn't feel to heavy to wear. Powerful and can lift lightly compacted snow.

Works very well blowing snow off vehicles and lite snow , weight is perfect , I’ve used it three times with about 3 inches of snow and will make this winter snow more bar-able for sure. It’s an awesome machine, I would recommend this blower!!

On my 4th tank of fuel now, so with reasonable confidence I can conclude this was a good purchase. Using it for clearing those nuisance (under 1 or 2 inches) snowfalls from my large concrete driveway and walkways. When I first read the specs re: mph and cfm I admit I was sceptical, but now that I've used it I can confirm, this thing blows like crazy! It even lifts the packed snow tracks (like when we drive on fresh snow before it gets cleared off), peeling them off the concrete. I have some crushed stones along one of the sidewalks and I have to be careful blowing there because it will actually blow the 3/4" stones all over the place! Come spring I have no doubt it will blow dead leaves and grass into the next area code. I can clear my drive and walks and both neighbours on each side of me in less time than shovelling just my own. The re-designed control grip is super easy to use. Some reviews mention the lack of a toe lip to make starting easier, but I can still step on the edge of the base, hold the shroud firm with my left hand and then pull the starter. It takes a firm grip because the engine has high compression (and 3.7 HP!!) and no compression release mechanism for starting, like some chainsaw engines. It starts every time on only 2 pulls though, as long as the carb is primed with fuel (10 pumps on the fuel bulb). It was well protected in the shipping carton, and comes with measuring container for fuel mix, spark plug wrench, spare throttle cable, and a COMPLETE recoil starter, including housing! My apologies to the Swedes and the Americans, but this German designed / Chinese built unit has y'all beat on this one, on both price and quality.

This blower has all the power you will need to blow your Leafs away. I used it for the first time yesterday and the Leafs were trampled down from the truck and were wet under the dry ones on top. This had no problem lifting the wet trampled leaf's up and pushed them as if they were dry Leafs. Easy to start after the first start. I didn't press the ball under the carb enough times the first start. Do it about 4-5 more than instructions say to . I used it for 2 hrs with no problems . Had to refill the gas tank once in the 2 hours. The straps are very comfortable. It is a little louder than I would have thought but ear plugs worked perfect for the noise. I would give this 5 full stars for Proformance and ease of use . It is well made and comes with extra parts and a spare pull start which is great . Only thing is it is a little hard to pull over so just put your foot on the bottom bar . I would buy this again if I ever needed a 2nd one.
