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.
