    Like the title says I've been tossing this one around in my head for a while and have finally come up with a plan
    02-03-09_1327.jpg
    the shaded area is the roller which will be covered in a carpet and a hood with spray nozzles to spray the roller the biggest problem has been trying to get the roller to spin and also to be able to set it the different heights
    I could have used a hydraulic motor but at some stage I might use it behind a quad so I decided to drive it with a belt from the wheels that's why it hinged at the wheels
    I think it will work if anybody sees any problems let me know

    Will you mount it on the front or the back, scarecrow ?


    If it's on the back will the weeds be pushed down by the wheels of the tractor.

    That is always a problem with them but on the upside you don't have to spray the whole field just to get a few weeds and you can use roundup as you wont be spraying grass
     
  4. have you had a look at any of the comercial builds scarecrow, I gather the pitfalls are preventing drip.....

    That's the one I've seen as well Sparkey to buy that here last time I looked was €2200 the suspension units are very expensive so I'm trying to work my way around having to buy them

    Not sure if dripping will be a problem as the pump is driven by the battery and not the pto with just a pushbutton switch so you can control the amount of spray that goes on the roller
    managed to do a bit of work on it yesterday so here is where im at

    my idea is just to hang the roller from the top rail with a couple of light chains so they can ride up and down under its own weight cutting out the need for suspension units

    It won't be hanging freely it will be hinged from the lugs on the hubs just using the chain's to more or less set the height and if it meets anything solid it can ride up over it if you know what I mean and I'm no expert this is going to be a bit of trill and error

    You could be right. where I think I will get into trouble is getting the roller to spin at the right speed to fast and it will spraying everywhere but I should have some leeway because it will be driven from the wheels so I can just drive slower

    I'm more or less making this from scrap the got lying around so if it goes wrong it's not the end of the world the only thing I need to buy is the tank and pump which can be got for around €400 some carpet for the roller as I think there is the special one and the Bearings that,s the one in it,s own housing not sure what are called

    Hi never made a weedwiper but used them alote for some contracting we have a logic contact 2000 uses brushes not carpet the carpet ones where crap if u can ger a brush of somesort insted it will work much beter also rember the roller has to spin the opisit way to what the wheels go round.
    ours has a pad you set from 1% -100% and it turned the pump on and off but we found it was better to run 100% and just turn it on and off at main swith if it started driping as the weeds where in patchs.

    No idea where I would get a brush but had thought about something like that the one I've seen had the carpet roller and it seem to work okay it's
    easy enough to change direction of the roller just put a twist in the belt

    it won't be finished by tomorrow the frame is the easy bit might be able to keep her scratching her head for a week:whistle:

    thanks wyn
