Well guys

Im building a licker,its modelled on a logic or chapman,im well on but need to get the correct size drive motor to rotate the brush of carpet,it will be running flat out when on so need rpm aro uh nd 25 or 30 but with little risk of stalling...really i need the size of the exact motor near enough..so i can order one cheers

Just be aware that there are new testing regulations coming in for the end of next year and your machine must pass those to be able to use it.

https://www.farmersjournal.ie/second-phase-of-sud-testing-delayed-until-2021-543738

This is a selection of the new regulations, there's quite a number more of them.

1 Tank: The tank will be checked for leaks during an inspection. The tank must have a lid, have a volume indicator and you must be able to empty it.


2 Pump: The pump capacity needs to be suited to the needs of the equipment and pulsations mustn’t exceed 10% of the working pressure. With the section valves closed, there must not be dripping from any part of the machine.

What kind of a motor are you using? Is it a quad or tractor licker?

Norto84

It will be running of the quads 12v dc supply.

Norto84

Cheers, it should meet the spec.

With a 12v motor ur looking at changing the pulley sizes to change the rotor speed...
Any reason your not going with ground drive?

Well i was going with the drive motor because is not a difficult install and its going to be the preferred spdcification with new regulations,provided i get a correct watt so one dosnt burn out every 3 weeks, i can set up pulley based on motor rpm or use a power regulator

Any link to these new regulations? Ya,If you have a plan for the drive motor work away.do ya not think it's over complicating the job a bit.hard to beat a belt and pulleys,for something that might not be used every day last thing ya want when ya hook it up is to discover that it wont turn and ya have to go looking for the multimeter..

It would be better than ground drive.

One problem with ground drive is that the rotation of the drum keeps the roundup from dropping off, the minute you stop the drum stops and the roundup starts to drop off. Having a 12/ motor running the drum would avoid that problem.

They haven't decided on the final regulations as yet but the broad outline is pretty much as the quote above. No drips and tanks must be capable of being emptied without any of the spray solution being lost.

Any weedlicker or boom sprayer less than 3m or pellet applicator, like for slug pellets, will have to meet minimum regulations by the end of next year. It was going to be this year but COVID19 forced another extension.

Would a hydraulic motor be an option on a tractor mounted weed wiper? Or would it be difficult to get the drum to rotate slow enough?
I like the idea of a week licker mounted on the linkage. Ground drive would work on a mounted licker too, but as already said, you’d have the problem of the drum dripping once you lifted it off the ground at headlands..

In the long term process of making a mounted licker and have plans to spin the rotor with a hydraulic motor.have nearly all the parts gathered up,carpet is the only thing left to get but getting time to put it together now is the problem..

Sounds interesting!

Hopefully this time now I get a chance to finish it,even made room for it in the workshop but there is always something more important ahead of it..

Be sure to post some photos when you have it done!

Will do,hope to get at it the weekend..

Neighbour has a Branded licker that is at least 10 years old but in good nick....he is going letting the land as retiring and offered to sell me his licker a few months ago for €500.....he keeps it in a shed during the Winters and I often licked rushes for myself in the past with it.
It has a working motor and a rectangular frame on it into which you place a 5 gallon drum filled with water and spray at correct mix.
Works off quad.
Motor mounted on frame....and plastic water pipe that feeds back to wet carpet......pipe fits into neat hole cut in 5 gallon drum lid.You prime the liquid mix then and off you go....At times when licking with it if you filled the drum too full some of mix might splash out slightly when working with it on bumpy ground as the pipe is not fully sealed where it goes down through the adjusted lid with hole in it for water pipe to feed through.
Would a sprayer like that pass these regulations coming in next year?
Not a whole pile of a point in me buying it if it’s not likely to pass these new regs.....I had say to my neighbour that I would tell him in next few weeks if I will buy it or not.

In my opinion, it probably wouldn’t pass....But, if the rest of the machine is in good order, a new tank wouldn’t be very expensive....Another option would be to get a grommet to seal the hole in the 5 gallon drum.

Would you probably have to take the current rectangular shaped housing off (which 5 gallons drum currently fits into?).....and attach a ‘new modern tank’ or would it be enough to put a grommet (which I don’t fully understand) ......on the lid of current 5 gallon drum to prevent spillages out while working in rough or bumpy terrain?

Wondering as well if it is enough to satisfy the new regulations that you know how much liquid you are filling into the 5 gallon drum each time?.....or do you need fancy new tank with graduated markings for exactly how much water is in it before you then add correct strength spray mix to it iykwim.

Again thanks for anyone’s thoughts.....I do not have the spraying course done yet and imagine that anyone that has would probably be able to answer my few questions,thanks.

The grommet should be enough. Basically, the brand new tank will still have a pipe coming through the top of it, sealed with a grommet. However, the grommet will also seal the air out, so a vented lid might be needed to prevent the sides of the drum getting sucked in as it empties. I’m not sure if vented lids exist for 5 gallon drums?
As for the markings on the container...it is certainly a requirement on boom sprayers. I doubt if it will be needed on a licker, but who knows. It’s probably something you could do yourself anyway, with the help of a litre measuring jug and a permanent marker...
