Rated 4.2 out of 5 by 19 reviewers.
Rated 5 out of 5 by Happy with initial use. Bought to use for weed killing over four acres of gravel driveway. Used for 10 hours and found it to be reliable and easy to use. The sprayer was easy to assemble and once again to store. Short term the product is exactly as advertised. Longer term durability is yet to be determined. I would recommend this to anyone looking for a 20+ gallon sprayer. John deere has an identical model that sells for twice as much. June 24, 2014
Rated 4 out of 5 by Does the job I have used this sprayer several times to cover my backyard of about an acre. It has a good spray pattern. Hooked up to a Cub Cadet riding mower. The only issues I had were that the cord for the on off switch is too short to reach the mower and too long to attach to the sprayer. There were times when I had to hold the line in my hand so I could turn off the sprayer when needed. Second issue is the metal brackets that hold up the sprayer arms are put on with a normal bolt and nut. One of the nuts came off due to vibration and I had to replace it. Designing anything that will have to work during vibration of a bouncy ride needs to be much more durable. November 11, 2014
Rated 2 out of 5 by 2 gals of Round-up on my lawn when tank split open after 3 yrs of seasonal residential use, I used this sprayer for about 3 yrs. for Round-up, Pre&Post-emergent herbicides and Demon (soluble powder) insecticide. While it works OK with very fluid mixtures, the thicker ones (like Surflan) tend to clog it. I was not very successful with the boom, it was inconsistent, from licking to dripping to spraying heretically; so I only used the hand wand as I could see what I sprayed and how it covered. Last week, while on a wild mission of reclaiming my yard from the weeds, as I was getting ready to pull-off the "filling station" by the deck, I realized I had a massive leakage from the tank. By the time I recovered from shock, I probably lost 2 gal. of Round-up. I rushed to unhook the trailer & flipped it on its back end until solution cleared the split. And then pumped it in my 1gal sprayer and finished the job 8 hrs later... To add insult to injury, Home Depot does not offer a replacement tank. We already tried to repair the tank using meltable polyethylene sticks, found on the internet and recommended specifically for these tanks, "as they have the propensity to split and break". Well, that did not work too well either, as the repair held for 2 more applications, only to loose the post-emergent this time. Well, at least it was on the same spot the Round-up started the job. And another 8 hrs later I finished that too, one heavy gallon at a time, in 95F/85%humidity... I would not wish that to my enemy, so no, I would not recommend it to anyone. While it is very convenient to mix 20+ gallons at a time and not have to lift, pull, or pump, it does the job, when the wand does not drip in closed position. But I have PTSD now, wondering if I could ever trust any plastic tank filled with 20-25 gal. of Round up crossing my lawn... June 10, 2014
Rated 5 out of 5 by 25 Gal. Tow-Behind Lawn and Garden Sprayer Easy to assemble, works very well,quick shippment, pump electrical connections to tractor contains all the parts needed. The pasture is rough and the booms would loosen up and have to be retighten often - easy to install pins to keep the boom arms out (normal lawn not a problem). October 30, 2014
Rated 4 out of 5 by Some disassembly and tweaking required during assembly... 30" hose should be replaced with a 36" hose. Small Wand Holder Clip should be replaced with a larger clip (1"-1.5"), so that Hand Sprayer can be stored as shown on front cover of Owner's Manual. On my unit, the pump suction 90 degree Elbow was at the wrong angle, causing the suction hose to have a kink in it. The hole in the tank wasn't at the proper place for the angle shown in the Owner's Manual, so the 90 degree Elbow had to be turned till it pointed at the tank hole. Make sure the suction strainer is in the tank sump before filling tank. After assembly, and rinsing everything out with plain water, I tested it with plain water. Everything seemed to work as advertised. Now I need a non-rainy day without excessive wind, to actually spray the weeds. May 16, 2014
