The system will make sure the planter maintains this value, achieving precise soil penetration, and consistent planting depth, without sidewall soil compaction. Just set the row-unit target margin value and the active pneumatic downforce system works automatically. Active pneumatic downforce adjusts automatically for changing ground conditions from 0 to 181 kg (0 to 400 lb) of downforceĪ hydraulically driven compressor works with the SeedStar XP, SeedStar 3 HP, and SeedStar 4 systems to automate downforce control.Pneumatic downforce, infinitely variable from 0 to 181 kg (0 to 400 lb) of downforce.Adjustable heavy-duty downforce, four settings, 0 kg (0 lb), 57 kg (125 lb), 113 kg (250 lb), and 181 kg (400 lb) of downforce.More available downforce options than any row unit in the industry This simple bolt-through design provides for a positive attachment of the gauge wheel to the gauge wheel arm and allows quick removal of the gauge wheel for service.Īdjustability of the row-unit is critical to good performance.
The bolt-through design utilizes an open bearing in the gauge wheel that allows an attaching bolt to pass through the wheel to the threaded hole in the gauge wheel arm. The shape reduces rocks and residue being picked up and thrown onto the drive chains and row-units, and helps to prevent rooster tailing of soil. This profile gently firms the sides of the seed furrow, ensuring a well-defined trench. The gauge wheel itself is made of durable nylon composition with a concave profile. Depth control is a function of the Tru-Vee openers, the downforce system, and the gauge wheel assembly. John Deere planters provide consistent seed depth control in all field conditions.
These hopper extensions can also be used for planting test plots. NOTE: Due to small seed size and low planting populations, sugar beets can be planted with mini-hopper style meters by adding hopper extensions and not using the CCS tank. Mini-hopper row-units, which are used only with the CCS, are compatible only with crops that the CCS is approved to plant. The knockout wheel is also recommended in conjunction with the double eliminator and flat seed disk to ensure seed is ejected from the disk.įlat and celled type seed metering disks are available to allow planting a wide variety of seed types. The double eliminator is set to cover a portion of the hole in the seed disk and is the mechanism to knock multiple seeds away as the disk rotates.ĭouble eliminators are required with flat-type seed disks only and should not be used with cell-type seed disks. By design, a flat seed disk requires higher levels of vacuum than a cell-type disk because there is no pocket or cell to hold the seed. The higher vacuum level will pull more than one seed to the holes in the seed disk. For difficult to singulate seeds, a flat seed disk and double eliminator is a viable alternative to traditional cell-type seed disks.
