Features Fertilizer Seed & Chemical
Accurate placement

John Deere has introduced two new air hoe drills that increase productivity. The 1835 air hoe drill applies fertilizer and seed in one pass. The openers, integrated with a 1910 air cart and variable rate seeding and fertilizer system, accurately place nitrogen, potassium and sulphur based fertilizers separate from the seed.

Placement systems feature active hydraulic down-force, depth gauging at the opener, low soil and residue disturbance and a positive closing system to lock-in dry, liquid or gas forms of nitrogen. The opener ensures accurate application of nitrogen precisely when it is needed and helps to reduce overall fertilizer cost by 10 to 15 percent.

Another big change for both the 1830 and 1835 air hoe drills is the frame design, which has undergone an advanced and rigorous testing program to ensure durability. John Deere is backing these air hoe drills with a three year frame warranty. The new design has robust ball joints to enable the frame to flex diagonally, relieving stress on solid frame members and avoiding frame failures.

The drills seed smoothly over uneven terrain because of the flex-frame design. The diagonal mainframe and wing flex help the openers hold their depth over varying soil conditions. The end result is uniform crop emergence, which is essential to meeting maximum yield potential.

Depth control settings are made easy with the new drills. The operator has a choice of two depth control options. Base equipment on the drills includes indexed depth shim packs and the new air hoe drills feature a reduction of adjustment sites by 60 percent. Another option is the convenient TouchSet depth control which allows the operator to make depth adjustments from the cab of the tractor on-the-go. This is an easy adjustment and very important in variable field conditions to help maintain consistent seed depth.

Growers have three choices for standards on the air hoe drills. The TruPosition standard, with a 550 pound trip force; the TruPosition standard, with a 350 pound trip force for rocky fields; and the spring cushion standard for light-duty applications.

Another feature of the air hoe drills includes a simplified hydraulic lift circuit with a reduction in the number of hydraulic cylinders. This system ensures consistent depth from mainframe to wing and maintains excellent seeding performance throughout the entire width of the machine. No re-phasing of the cylinders is needed and there are fewer hydraulic components and hoses to maintain.
