Chapin 61900 Made in the USA 4 Gallon Tree and Turf Pro Commercial Backpack Sprayer with Stainless Steel Wand, 3 nozzles, 3 Stage Filtration, Translucent White

For years I have wished I had a backpack sprayer for my 5 fruit trees and other house and yard work, but I could not justify the additional expense when I already had a Solo 2 gallon sprayer that worked fine. When I took on spraying my neighbor's trees to help her, I immediately ordered my Chaplin 61900 sprayer (after careful research). It has made my spraying so much easier and faster that I kick myself for not having done it sooner!No longer do I have to spray, pump, spray, pump, spray, pump, etc. I now pump as I walk along spraying, and the built in pressure gauge tells me how much pressure is in the tank. Thus my coverage is more consistent and the task takes less time.At 74 years of age I was a little concerned about the 34 pounds on my back, but new that I could just half fill it if it was a problem. I have a table I set it on and then slip into the harness, and I find the weight a non issue with the good strapping to properly support it.Today, while spraying for spiders, that as I finished up the seventh gallon, it was getting hard to pump.Having used it already for at least 8 hours already this summer I noticed immediately the added resistance. There are three screens in the system, and a quick check found the first two clean as a whistle. I had to take the hose off the handle to get to the third, but as soon as I did the cause of the problem was obvious.Some of the viscous spider chemical had not dissolved and had collected at this last screen. After cleaning the screen, the pump was again working well. Next time I use this chemical I will dissolve it thoroughly first.Don't wait until you have to have it. Buy it first. A quality, efficient piece of equipment.

Ahh a sprayer that works! After a bit of rethreading twisted straps and getting the backpack adjusted comfortably for my frame, I first filled with plain water to check for leaks. Fantastic, no leaks right from the box. Now I don't like to spray insecticides unless absolutely necessary, but I've got Catalpa trees that get ugly Catalpa worms this time of year, and they just destroy those beautiful big leaves. This sprayer allows me the power and pressure to get the job done. I do have to use a 14 ft. step ladder to reach higher to the tops but nothing short of a full commercial motored sprayer would do that from the ground. You can add mix to the tank without getting a face full of air and poison, and the pressure gauge on the wand is great and useful. Do read the manual to know how to clean the filters and maintain the pump. Now I've got a sprayer to spray my fruit trees and squash bugs on vine crops that's quick and easy to use and should last many years. Parts look to be easy to get and replace should the need arise. Over all I'm very pleased with this unit. It beats the heck outta small hand held tank sprayers and no motor or batteries to mess with. If you've got a lot of trees or gardens to spray, this is an easy, cheap way to go. If I've got a lot of trees to spray, I just premix whatever in a 5 gal. bucket and pour over as needed.

We finally gave up on our hand held 2Gal sprayers and went with this one. Appears to be nicely constructed, and the manual details rebuilding steps as well as a parts list - so even if it breaks you'll be able to service it.I know it's petty, but I reduced this by one star because of the straps. Not because they are uncomfortable - they were attached COMPLETELY wrong. I spent half an hour trying to figure out what *I* was doing wrong since I figured there was no way something from the factory would be set up incorrectly. This one was.Be prepared to remove the straps from the various clips/etc and re-rig this when you get it.Set the sprayer on a table right side up with the shoulder strap connectors on the top of the tank closest to you (you should NOT be able to read 'Chapin') on the tank.The shoulder pads have a 'plain' side and a side with the strap sewn to the face. The PLAIN side should be facing the tank, the strap side faces towards you. Each shoulder strap has a couple of curves. From the top down, the first set of curves should be to the OUTSIDE edge of the sprayer. They should look like THIS: ( ). The second set of curves face INWARD. They should look like THIS: ) ( You know it is correct when the chest strap can go between the 2 shoulder straps and not twist anything.Next, look at the LUMBAR support. It has a flat edge and a curved edge. The curve faces UP. It too has a plain side and a side with straps sewn to it. in this case the PLAIN side is the side that will face you. Each side has a plastic clip. That clip attaches to the metal stand, just under the main pump rod. Clip them on so that they twist the least. If you disconnected the shoulder straps from the lumbar support, re-attach them without twists.NOW you can put it on. Put an arm from the middle of the tank through the shoulder strap. Grab the other side and put your arm through. It's just like a coat. Adjust the shoulder straps to carry the tank where it is comfortable on your back, then attach the chest strap from one side to the other. Adjust it so the shoulder straps don't wander around. Now grab the belt strap and wrap around your waist and attach it to the other side. Adjust as needed for a comfortable fit.
