CountyLine 40 gal. 5-Nozzle Trailer Sprayer, 5302940 is rated 4.1 out of 5 by 13.
Rated 4 out of 5 by from Does its job Bought 2weeks ago so far it does the job, but I read reviews and they were spot on 40gallons in and the pressure gauge filled up with liquid and started leaking like crazy. On the bright sideget a new oil filled gauge, I am now 240 gallons in and it works great could not be happier it is well worth the money.

Rated 5 out of 5 by from Good buy does the job it was built to do Pressure gauge filled will liquid 5 minutes in but I knew that was going to happen because of the reviews I read, had new oil filled gauge on hand ready to replace.

Rated 4 out of 5 by from Good value sprayer for turf lawn I have the 30-gal. sprayer that I have used for two full seasons now. I use it on my lawn for spraying herbicides, fertilizer, and insecticides. It's a good value for what I paid for the unit, so my assumption is that the 40-gal sprayer is most likely the same value, with same pros and cons. I don't think the 30-gal trailer sprayer is available anymore(?). It works well out-of-the-box, but there are some things that I felt were in need of slight upgrades. First off, although it sprays as it should, I felt that the 2.1 GPM pump was undersized and should be of more flow, and that was with 4 spray nozzles on my unit. At the start of the second season of use, I upgraded the pump to a 3.8 GPM pump and its much better now. The 40-gallon sprayer appears to come with a 2.4 GPM pump, out to 5 nozzles. From my experience, that is something I feel would need to be upgraded to a minimum 3.8 high flow pump. It may work with the 2.4, but its not going to spray what I consider "beautiful", out to 5 nozzles . The pressure gauge is cheap and not a fluid filled gauge, so the needle on it bounces all over the place, eventually failing. This is an easy and inexpensive upgrade and one I consider a must. Get a fluid filled pressure gauge to replace the chintzy gauge the unit comes with. The drain plug is plastic threaded that screws onto the molded threads of the tank. The threads on the plug and the tank eventually wear with the constant screwing on and unscrewing of the plug. It's easy to over-tighten this and the threads just cross thread, being its just thick plastic. Mine now leaks and I had to double up the rubber washer inside the plug to help mitigate the leaking. Some sort of rubber cork type plug, in lieu of a screw on type plug would work better. This is something I'm going to change on it next season. Although it works fine, I hate the cable with the battery clamps, but that is just my personal dislike with it. It may not be a problem for someone else. The battery on my rider (JD X590) is up front, so the cable has to run past me and under the hood, and then use the rather cheap battery clamps to clamp to the battery lugs. On tight turns, I sometimes stretch the cable to its limit which can pop the clamp/s off the lug/s. Not what I would consider very safe, so I have to watch the tight turns. It could get rather "sparky" if you're not careful. Next season, I plan to integrate a permanent electrical plug at the hitch of the mower that the pump cable plugs into, and wire the mower side of the circuit through an ON/OFF switch on the dash of the mower. One of the valves on the manifold broke this year. Not sure how that can happen but it broke. It always felt very tight, even when it was new. It finally broke, so I had to replace the manifold this season (2nd season). The hand gun sprayer works very well. I use this to spray aquacides along the water edges of our pond. With the pressure dialed in right (~30 psi), I can reach out with the spray a good 40 feet. It has a high quality brass nozzle and works well. The spray tips on the boom are "universal" type spray tips and can be changed/swapped with other tips of the same type to change the spray pattern, flow, etc. I have 4 different sets of tips for different spray patterns. This is also nice because it makes it easy to replace a faulty tip. I use the "TeeJet" tips and there is a wide range of tips available in this range. Overall, its a good unit for the price. A few upgrades as described make it an exceptional unit for lawn care nuts like me. Happy spraying!

Rated 5 out of 5 by from 40 Gallon Trailer Sprayer Works really well. Wasn't hard to put together. Did have to tighten up some hoses. Everything worked well while spraying in our pasture.

I recently bought a 40 gallon county line yard sprayer. I plan on using castor oil for the moles and gophers. Can you recommend something to mix with it besides water so I can get a good application with out burning up the pump??

Asked by: Snurd
Should be okay with mixing the castor oil with water and running through the pump, according to our compatibility guide, just need to make sure you clean pump thoroughly after use.

I own this product and use it to spray our fields. I now am looking for a tank to water some trees we are going to plant. Using the pump and wand would be too slow. Does this have a drain tube on the bottom that I could rig for gravity flow of water?

Asked by: Jomavrick
There are two bulkhead fittings on the bottom of the tank. One is for the intake line that connects to your pump, the other is for a bypass line, the line that returns to the tank to help raise or lower your pressure. If you’re not planning on using the boom or the handgun when you go to water some trees, you can close the shut off valve on the intake. Unscrew the shutoff valve from the coupler it attaches to, being careful as to not lose the washer in there, and then drop the line down to gravity feed, then re-hook up to the coupler when you want to use the boom or handgun again. That way, you can also close the shut off valve to go to the next tree without losing any water in between. The shut off valve is a ¾” garden hose thread, so if you wanted, you could add a short hose to it if needed, like a section of a garden hose that you trim down, as you don’t want to use a full garden hose.

Can the spray boom rotate so that it can spray sideways, parallel to the tank? I want to use this to spray a row of hemp plants. Thank you.

Asked by: Buygoodwine
The boom does not rotate. You would have to fabricate something up yourself to spray like that. We often get asked similar questions by vineyards and have always told them the sprayers are not designed to spray something like that and that they would have to fabricate something to allow them to do that, but for the question here, no the boom does not rotate.
