Culta - Model CW -Dual Purpose Rotary Rod Weeders
The Calkins Culta-Weeder, a dual-purpose rod weeder, was initially developed to control weeds in summerfallow fields through the unique design of square rods that rotate in a reverse direction. This mechanism effectively forces weeds upward to the surface while also setting the moisture line in the soil, which is vital for conserving moisture in agricultural practices. The Culta-Weeder helps form an insulating mulch of loose clods, soil, and residue on the soil surface, reducing surface evaporation and optimizing moisture retention. Farmers can optimize this process for varying conditions by using the device immediately after initial tillage and ensuring subsequent operations maintain the same depth, thus ensuring a firm and moist seed bed for planting. The Culta-Weeder also features a rolling tongue for improved operation on uneven ground, and it can transport easily on highways. Key specifications include heavy-duty frames, spring-loaded units, adjustable hydraulic pressure set values, and more, ensuring durability and efficient performance in a range of soil and trash conditions.
Dual-purpose Rod Weeder improves yield.
Rotary rod weeders were initially developed to control weeds in summerfallow. Their design is highly effective: square rods rotating in a reverse direction forcing weeds upward to the ground surface.
Ironically, it is not uncommon now to see a rod weeder operating in a completely weedless field. But for another purpose: to set the moisture line in summerfallow.
And that`s important. Loose soil will lose moisture to the depth of tillage -- regardless of whether you plow or disc. Consequently, this soil type should not be allowed to extend to the surface, since moisture travels upward through compact soil by capillary action.
That`s why knowledgeable farmers utilize reverse rotating rods to compact their soil. This process allows an insulating mulch of loose clods, soil and trash to blanket the surface and help stop evaporation. To set the moisture line, just immediately follow your initial tillage with a rod weeder.
Then, in each succeeding operation, avoid running the rod any shallower until moisture is held at a depth suitable for seeding. Your final rodding pass will make a firm seed bed in moist soil.
Clearly, the rod weeder is an indispensable tool for all soil affected by limited rainfall. Without this field advantage, you would not have sufficient moisture to grow crops successfully.
Is the rod weeder misnamed? Yes, or at least undernamed. It purposefully kills weeds. But it performs beyond initial duty by adding many bushels to your yield. Apply this knowledge with a Calkins Culta-Weeder and you`ll achieve the lowest tillage cost per acre, while covering more acres per unit -- in all kinds of soil and trash conditions.
ROLLING TONGUE LEVELS UNEVEN GROUND
Farming uneven ground? Optional rolling tongue design permits Culta-Weeder to operate independent of the hitch and adapt to multitude of terrains and conditions. On the road, Culta-Weeder transports like all rigid tongue machinery for easy highway travel.
