Spring planting season is right around the corner and now is the time, if you haven’t already, to pull out those planters and get them ready for #plant2017!
The first step in planter maintenance is checking the metering units. They have to work well or you’ll get frequent skips, doubles and triples, according to a Penn State Extension article on planter preparation. For optimal performance, take metering units apart and clean with soapy water. Replace cracked covers, broken fingers or worn seed brushes.
Accurate seed depth placement can be compromised if planter units are loose or wobbly.
“We go through the planter units every year to make sure they are set up properly and planting the way they should be,” said Randy Campbell, of Campbell Brothers Farms in Minerva.
Look across the planter to make sure units are the same height all the way across. Loose bolts or additional bushings needed are often the cause.
2Wear and tear
Consult the owner’s manual to determine the minimum diameter necessary before seed opener disks need to be replaced. Always replace disks openers in pairs.
“We question it every year,” said Campbell. “Our openers are barely worn out after a year but we might replace it anyway.”
Worn disc openers can leave a seed trench that is “W” shaped rather than “V” shaped, causing poor seed placement. To test this, stick two business cards between the openers and move them as close together as possible.
For standard blades, the distance between the cards should be 2-3 inches — heavy duty discs may leave a space of 1-1 ½ inches, according to Chip Turner, with Burrus Seed.
If the space is less than desired and blades are still in spec, remove shims and adjust blades inward until the make proper contact.
Seed tubes may also wear, causing the ends to curl inwards. Seed tube guards need to a have a minimum width and fastened correctly or seed tube damage is likely. Seed firmers help press seeds to the desired depth. If worn, they may need to be replaced as well.
Others things to check for wear: coulters, row cleaners and closing wheels. According to Ohio State Extensions C.O.R.N. newsletter, John Fulton suggests, inspecting closing wheels or discs and ensuring bearings are in good shape and that the down force spring is properly set. Replace wheels if worn excessively.
Check alignment of coulters, opener disks, and closing wheels by using a rope, and running from the front coulter to the closing wheels. Firming wheels, seed openers, and coulters should all be in line.
Closing wheels should not run on top of the seed furrow. The insecticide boxes should have no holes or cracks. Tubes should be blown out with air as well as the slot on bottom of meter, according to Penn State Extension.
“Every year we go to the books and attend planting clinics to remind us what needs to be replaced,” said Campbell. “We try to hit a planting workshop or training to pick up a tip on something new or something we may have forgotten about.”
Check with your local extension or equipment dealer to see if they are offering any upcoming clinics or training sessions.
