The Bourquin Organic Weedpuller was designed to brush along the top of the crop to remove tall weeds in the row.   A series of wheels, which are driven hydraulically, rotate like an old wringer washer; grasping weeds, which extend above the crop row, pulling them upward and out.  The concept is uncomplicated.  Very simple machine adjustments make the machine easy to operate and extremely versatile.  However, it may seem simple enough, but there’s a great deal more going on than simply two sets of wheels running together.  The machines work on a variety of different row widths and numbers.  The Bourquin Weedpuller can be front or rear mounted.

Early on in our field demonstrations we would have farmers tell us that they liked the concept, but it needed some more work.  They told us to come back when it was perfected.  Well WE ARE BACK.

We are hardly the same machines that we fielded several years ago.  Obviously we think that the best program is to utilize the Weedpuller consistently, but we really shine when we make a crop out of a weed field.  It is not uncommon to hear stories of the WP saving a crop that other-wise would have been lost or  destroyed.  It would be interesting to know how many millions of crop dollars have been saved.  Once again find out what we have in the arsenal.  The various new features mentioned here either  have new patents, or are in the patent pending stage.

Weedpuller (101) 

What I’ve learned (and what farmers need to know)

  1. The Weedpuller pulls glyphosate resistant pig weed, etc.
  2. Farmers – gone are the days of losing a low lying crop to weeds
  3. Not every farmer needs a Weedpuller, but every farmer needs to know that there is one available
  4. The Weedpuller is one tool, among several, to maintain normal weed control
  5. The need for a Weedpuller is accentuated when unexpected and maybe prolonged rain fall occurs.
  6. For organic farmers, excessive rain fall may overcome even the best historical weed control programs
  7. We’ve learned that slowing the revelation speed of the roller/tires improves the pulling as opposed to the jerking action of high speed rotation. Picture how a reel on a combine functions. We grab the weed and the forward motion of the tractor does the pulling. This is similar to how a weed would be pulled by hand. The most common error- the wheels are too fast.
  8. The notched Posi Pull Disk have two actions  1. When the weed is tensioned between the rollers and the ground, the notched blade kicks the weed stem in the side, increases the pulling power, somewhat like the compounding pulley on a winch.  #2 When the blades mesh they clutch the weed between the blade notches and the forward motion of the tractor pulls the weed out. That’s the reason we have been able to pull weeds with 1 •” stocks.
  9. Our first blades were too sharp. The new blades are thicker, blunter and have a softer strike point, these aid in pulling not cutting weeds.
  10. We have made specialty prototype machines for individual farmer’s needs. As a result we have made monumental accidental advances for our conventional machines.
  11. To get a narrow row, we incorporated a rubber tire that runs against a roller. The farmer came back and said the rubber/tire/roller worked substantially better than the tire against tire combination.
  12. Again to get a narrow row unit we combined a larger tire against a smaller roller. This is reversed on the back sets of the tire/roller. It is a little hard to explain except when the weed gets half way through the dueled roller/tire combination it has to do approximately 2” jog, which in effect utilizes the corners of the tires.
  13. Brief Recap.  #1 The Weedpuller utilizes the forward faces of the front roller/tire combination, #2 utilizes the back combination roller/tire face #3, the notched posipal set, #4 and #5 the corners of the tires as it does the jog. Each of sets would pull weeds separately, but when you combined those five steps, in what I call redundant control, we are extremely effective.
