Default 3 point pto driven tractor sprayer

I have been looking for a sprayer to use to establish NWSG and trees, and I've found one that is a 3 point attach sprayer and it has a pump that is driven off the PTO. The only sprayer I have borrowed before had a pump that ran off a battery, and you simply turned the switch on/off when you wanted the sprayer to start/stop. My question is with a sprayer that has a pump driven off the PTO, how do you start/stop the sprayer? Is there a release valve or something to keep the pressure at a constant PSI while the PTO is running? Do you just turn the PTO on or off to make it start/stop spraying? Anyone used one of these before?

Also, should I buy one like this or look for one with an electical pump?

thanks

Great minds think alike. I am buying one of these in the next month or so:

Note the very positive reviews. Seems ideal for spraying in tight areas, just using the PTO to turn it on and off, like any other implement. The 50' of hose with the high pressure hand sprayer is nice too, for tree work.

PTO runs all the time. There is a valve that turns the boom on and off. There is also a pressure adjustment, usually a screw type. With the boom on, the excess flow runs back into the tank serving as agitation. With the boom off, it all runs back into the tank as agitation. Unlike the electric pumps, you will have much more flow than you probably need.

My little 12' sprayer has a manual valve that you just reach back and flip to turn boom on/off. I also have a larger sprayer set up with 3 separate boom sections, all controlled by electronic valves. The boom sections and the spray pressure are controlled from the cab with a electronic control box.

In general, after the PTO pump, there will be a pressure regulator valve, which will have a bypass going back to the tank. On the line going to the boom (if you have one), you would likely have a 12 volt solenoid valve to turn the spray on/off

Are you planning to pump glyphosate? That pump (Hypro 7560C) is cast iron and not the best for pumping fertilizer and glyphosate. I would recommend the "silver" models - but they cost quite a bit more.

Thanks guys. I'm always amazed at how helpful everyone is on here and there's always people out there who will have the answer no matter what questions come up on here.

The one I was looking at is a used one and it's going to be auctioned off in a week. I looked at it briefly, but I don't think there is anything electrical on it, as far as having "a 12 volt solenoid valve to turn the spray on/off" as you said Redonthehead. Is that possible, or maybe I just didn't know what to look for? Is it possible that it just has a simple switch that you move back and forth to allow the spray to come out the boom or to shut it off? I think that is what you were saying hrcarver, correct: "My little 12' sprayer has a manual valve that you just reach back and flip to turn boom on/off." Can you easily reach that while sitting on the seat of the tractor and just reach back to flip it on/off?

thanks

I have tried all three grades and never been able to any difference in durability with roundup. I have also tried the highest grade pumps for fertilizer and it didn't last one season. Larger pumps do usually last longer than smaller pumps for whatever reason.

For roundup - I'd not let them freeze, keep a little oil in them to keep them from rusting up, and take my chances with the cheap one.

For fertilizer - Buy a new spare pump for when you are done, you will need it.

I bought a 55 gal Fimco. I just open the rear window of my cab and can easily reach the valve. No problem with and open tractor either.

I like to run Nutasol through my sprayer after each use. My PTO pump has been running flawlessly for years now (knock on wood).

I use a fimco 55 gallon 3pt type, pto driven model and I love mine. I didn't want to have to run wires or worry about another battery. I also added a wand/gun sprayer to mine as well so I can boom spray or spot spray as I need to. I have run gly and cleth through mine for 2 seasons now without an issue (just make sure you have all the water/fluid out of it during winter storage). I did have to by my pump seperately and paid about $200 just for it. I even use it to water fruit trees in the summer when they need a drink as well. I have different application tips and I like how I can vary the height based on crop/weed height or to reduce wind drift.

Rockin-G,

Thanks for the heads up! Gemplers is checking to see if I can get the XL series pump (totally corrosion resistant) as an upgrade, since it ships straight from the manufacturer.

I personally prefer either a a 12 volt or a ground driven pump. But it all depends.

It's the actual connection at the pto I don't like. No real safety mechanism to assure the pump shaft can't get put in a bind. That's been my experience anyway.

One thing I will throw in with the pto sprayer. I used ours on our kubota(3130) with hydrostatic drive. With the sprayer completely full the tractor had a hard time keepin a consistent speed and over applied. I was tryin to keep a consistent speed and trying to keep my rate the same. The hydrostatic drive would loose rpm and then I would soak what I was spraying. A gear drive tractor would be better suited for a pto sprayer. That's my experience.

So with a 12 volt pump, could I just run wires from the battery on my tractor to the pump and run it off that, or do I need to get another battery just for the sprayer pump?

thanks

You can run wires from your tractor battery. You probably want an in-line fuse. Some tractors have a 12-volt accessory connection on the rear.

I don't believe you said what the sprayer has in the way of a boom, but I don't know of anyone running a standard boom with 7+ nozzles with a 12 volt pump. Its going to need a PTO roller pump.

I have a special three nozzle boom I use to spray rows of seedlings with, and a 12 volt, 3.8gpm, 45 psi pump will handle it, but runs the majority of the time. As yoder just mentioned, my Deere has a 6 place power strip to plug in 12 volt accessories.

The boom on it was 10 feet wide overall, guess I'm not sure how many nozzles it had. Are they usually 2 feet apart or what? Guess it would have 6 nozzles then (5 spaces at 2 feet each)??

A 10 or 12 foot boom can safely be run with a 12 volt pump can't it? Guess they would have at most 6 or 7 nozzles?

After some of the recent posts, I'm thinking maybe the electric pump might be the better option with a 10 or 12 foot boom?? Anyone else have experience with one or the other (PTO vs. electric pump) and the pros/cons of each??

This is a stupid question, but how do you tell the difference between a tractor with hydro drive and gear drive? I think my massey 1080 diesel and my dad's massey 165 gas are gear drive. If you engage the PTO, the PTO will keep running the same speed even if you stop the tractor and put it in neutral. They both have the "multi power" Hi/Lo where hi give you engine breaking, when it's in lo on the multi power, you have no engine breaking.

thanks

I like yoder's response. Preferably, you already have an auxillary outlet.

Otherwise, you may be like me, and have to run a very long set of external wires all the way to the front of the tractor.
The in-line fuse can be annoying, but is definitely a good idea.

Make sure you have a switch in there somewhere. Preferably, my atv sprayer would be atv mounted, and this would not be an issue. but we work with what we got. I often think about one of those jump-start charging units for vehicles thoug. There too, if you have an old spare battery, that can work as well.

Hydrostatic transmission usually have a High/Low range you select with a leaver. They typically have an dash mounted throttle that controls engine speed. A foot "accelerator" is used to control how much of the power generated is applied to the wheels. Like a car accelerator, the more you push it the faster it goes. Unlike a car, stepping on the heal will reverse direction.

These are great for operating a FEL, but for most other tasks (especially spraying) I like a gear drive better (which is what you have). Most have some kind of latch system so you can lock the foot pedal in a particular position which is supposed to keep a constant speed. It doesn't work great.

Thanks,

Jack

I run a 8 nozzle set on my ATV with a 12 foot boom (20 inch centers). We had to up our electric pump size to handle the extra flow. Believe we went with around a 6 GPM pump(Will check the pump for sure when I get home). Has plenty of output this way. The electric pumps can be picked up at most local ag supply shops. Of course with the higher GPM pump we added a PSI regulator which gives us agitation as well as tip PSI control under different applications.

As far as the Hydro Transmission if you have to push a pedal to make the tractor go forward or backwards you will have a hydro (Don't confuse this with a foot throttle). The farther you push the pedal the faster you go. To brake you let up on the pedal. You may be able to select between different ranges for some speed control. With a gear drive you have to select a gear that you will operate in (example High range 4th gear while some have three selections ranges) and you have to select forward or reverse.

A 7 nozzle boom will require somewhere in the ballpark of 2 gallons per minute (depending on nozzle/pressure). That's cutting it awfully close for the electric pumps, but the bigger ones could probably handle it. I have seen 12v 3.8 gpm pumps for sale, but I've never used one.

I think most electric pumps will only do around 2gpm maxed out. Compare to around 10gpm on the smallest roller pumps.
