How do you use an old style hardi sprayer?

raher1

I bought an old style hardi sprayer it's the 300 gal one. It has the yellow round tank and booms. I find it hard to get it working evenly. It's sprays it all out at once or not at all.whats wrong?

Is it calibrated correctly? Doesn't sound like it will pass next year's sprayer doe.

What doe?

All sprayers have to be registered online before June this year and operators too. Then sprayers have to be tested, first test lasts 5 years then every 3 year's after that. In the farming Independent today, heard it was coming ages ago though.

Does that include ones owned by farmers not contractors?

All sprayers.

Be as well get someone into spray now. Only for having your own sprayer is handy for keeping after weeds.
Need to fix up mine too

Any idea of the cost?

Page 6 under the heading "changes afoot for sprayers with online registration scheme"
In the tillage comment section but still reinvent to all.

Wonder do weed licker things come into it.

It says working with chemicals so I say yes but not now for weedlickers. The knapsack is next.

Take each nozzle apart and make sure the mesh filters are clean, also check the nozzles are all the same size and color

Then work away till the chain holding the pump comes loose, and you break the diaphragm sphere off the pump. Then find that Hardi make their money on the price of the plastic fittings.

It works away ok when parked. When working it spills out all the stuff.

I think weedwipers are covered and knapsacks are already underway, for knapsacks you will need to be certified to use one by the end of next year ish

It's all here I think.

Happy reading

Just waiting for some training companies to start doing knapsack courses, far too few in Ireland so far.

Has anoyone a copy of the standards that sprayers will be required to comply with?

Looking for some help.The needle on the pressure gauge on my hardi 300 litre sprayer jolts around and you have to put high revs on the tractor to get all the nozzles spraying.I took the pump apart and all seems ok.I noticed today that on one of the booms one of the middle nozzles is not spraying unless high revs on the tractor but the nozzles either side of it spray fine. Could this cause the needle jolting on the gauge or is this coincidence. Any ideas???

Sounds like that nozzle is blocked. Fit a new one and new mesh filter. You need to be clinical with the water you use. If you fill from a mains supply water will be clean. This saves A lot of the headaches l've found.


Is the sprayer pulsating ie spray coming out in spurts? The pressure in the ball regulates this. It needs to be 30psi. Also ensure the circular diaphragm isn't perished (~€20) It pulses in and out when you are spraying.

Apart from leaking hoses or cracked nozzle bars, feck all else goes wrong.

Re revs. If you are operating in 540 pto then revs will be high to get a good spray.

Hope this helps

Thanks is there a diaphragm inside that ball I did not open that.ill swap nozzles see if it works on another part of the boom.thanks again.

Sorry maybe l'm not calling it the right name. It's beside the ball. Its a black plastic circular cao. You'll spot It easily. It pulses in and out when the sprayer is working. Be very careful of pto if your observing it when it's running!! It perishes easily and will start leaking then.

Run rhe sprayer with just water in the yard, clean concrete preferably. It's easy then to spot leaks and where things are going wrong

I know what your describing it looks ok it, pulses and there are no leaks.ill investigate further thank you

ganmo

anyone know of someone that'd give one a good service, I've no head for working with those little plastic bits.

Just spent hours trying to get sprayer (Rau) to actually pump. had a spare pump so fitted that. That necessitated a different driveshaft end, which in turn needed a new hardy-spicer cross. Trip to town, and 15 Euro. Wasn't a bit better.:mad:
Then on doing a step by step strip down, found a mysterious non-return valve fitted the wrong way round.:rolleyes:

Does the mist from the nozzles actually pulse, or is it just that the needle is flickering all over the place? If the needle is flickering it may be that the glycerol solution around the needle is gone, when this happens the needle wont sit steady.

What revs are ye supposed to spray at? I leave the tractor tucking over

Spray at whatever revs you want as it's about pressure and forward speed.
Set your revs, adjust pressure to requirement and off you go.

Pressure gauge doesn't work. Don't know why. Go about 7km

The only sprayer that doesn't need a pressure gauge is a budget.

I would say that the needle is flickering there seems to be a steady flow from the mist.I did think that it needed pretty high revs to get all the nozzles to spray so between that and the needle flickering I assumed there was something wrong. Should all the nozzles spray even with low revs ? ?

Revs have nothing to do with it. There is a tap that you turn manually to adjust pressure.

Well that has to be closed in fully and rev applied to the tractor to get all the nozzles to spray

Start with the basics, take off all the nozzles and make sure none are blocked, there is also probably a filter on the main suction line that could be blocked.

After all that if its not working you need to start digging deeper, it could be a seal gone in the pressure unit up top

Well I think I have checked everything at this stage. Ill check to make sure there is enough water getting to pump in first place (maybe there is a blockage there somewhere )and after that i don't know i might replace the seals if that's what they are called in top section of the pump although they looked fine !!!!......

sounds like its the seals in the pressure control unit are gone and too much water is getting back to the tank, a highly sophisticated way of checking this is to put the sprayer in spraying mode with low revs on the tractor ,say 1200, and clamp the return pipe from the control unit with a g clamp or vice grip, keep tightening the clamp and if the pressure increases the seals are gone in the control unit

thank you by control unit do you mean the unit where the handle goes over and back.took this apart has a ball valve inside and looks to be ok.I will try the test you described. Which pipe is the return pipe .

The return pipe is the one going from the pressure control unit to the tank.
