Furrow V Closer
The concept for the Furrow V Closer came about in 1992. It addresses the issue of the furrow being left open in no-till and minimum till fields.
If you use no-till or other alternative till planting methods, then you know how difficult it is to properly close the seed furrows.
The Furrow V Closer comes up superior in closing the seed trench ahead of the press wheels in heavy, wet soils. It does not run in the seed trench, but rather to the side of the seed V opening, making it easier to place starter fertilizer and/or chemicals in the furrow with the seed.
If you are practicing reduced tillage and especially if you are planting on the early side, be conscious of soil temperature variability. Temperatures under heavy residue are usually several degrees colder than they are in bare fields. The top soil is always warmer than the soil at a 3″ depth (as much as 10° difference). Corn will germinate at soil temperatures of 45°-50° F., but lower temperatures may significantly decrease the uniformity of germination.
This is a very distinct advantage of the Furrow V Closer over the seed firmer wheels.
By using the Furrow V Closer and the Rebounder in wetter soils you will achieve greater results. The gauge wheel tire and angle of pitch can be used to accomplish this.
The press wheels were designed to firm the soil over the seed in tilled seed beds where the soil practically falls in over the seed.
With a firm ground resulting from minimum tillage situations, the double disc openers leave compacted furrow sidewalls that resist closing over the seed even with increased pressure on the press wheel(s).
Increased pressure compounds the compaction in the seed zone and contributes to crusting problems above the seed.
If the sides of the furrow do not close in over the seed, there is poor seed to soil contact.
If they crack open and expose the seed, the seed dries out and does not germinate.
If they close at the top without soil directly above the seed, the seed may germinate, leaf out, and then be unable to penetrate the crust above it and die.
The FVC stitches the seed V shut so it does not crack back open on a hot, windy day after planting.
Make sure that the planter does not rest on poly Furrow V Closer discs during storage. Furrow V Closer discs can warp.
Check the tail section’s full range of motion for adequate FVC clearance. If you have a field you don’t need to use the FVC on, just remove the bearing, hub, and disc assembly and not the shaft it runs on. This saves time in re-setting the FVC when you need it. More pitch and less depth move the same amount of soil.
Reduce the down pressure on the press wheels! This helps prevent compaction which allows quicker emergence and at the same time saves press wheel bearings.
