Top ten pre-season planter tips


Level the Planter

Check the hitch height. The tractor hitch height may vary due to the tractor tyre size, tractor manufacturer, and the type of planter (Draw bar vs. 2 pt hitch). Refer to the planter operator’s manual for set up. Make sure the planter’s tool bar is level (vertically) or running slightly up hill. When planters tip down, coulters run too deep and closing wheels run too shallow.

Check Bushings and Parallel Linkage

Worn bushings increase row bounce which increases seed bounce. Stand behind the row unit and wiggle it up and down and back and forth checking to make sure bushings are tight.

Drive System

Check every chain. Kinked chains cause shock and vibration in the meter. Start with fresh, lubricated chains and check them daily. Include transmission chains, meter drive chains and insecticide box chains.

Calibrate Meters

Calibrated meters can help add more per hectare. On finger units check brushes, fingers, springs, back plates and seed belts for wear. On air or vacuum planters check brushes, gaskets and disks or drums for cracks or wear. Replace all worn parts. A good cleaning will also help improve performance.

Test double disk openers

Test to make sure there is good contact between the double disks. Slide a business card from the top down along the front of the disks until the card won’t lower any further. Mark that spot with chalk. Then, take the card from the back and slide it forward until it stops. Mark that spot and measure the distance between the two marks. If it is less than two inches (5cm), reship or replace the disks. In general, the disks must be replaced when they lose 1/2 inch (1.27cm) in diameter.

Check Depth Wheels

Check rubber tyres for cracks and wear. Wheels should run tight against double disk openers to ensure seed furrow does not collapse. Reduced inner diameter gauge wheels help to reduce sidewall compaction in wetter conditions such as reduced or no-till.

Seed Tubes

Inspect seed tubes for wear at the bottom. If the tubes have a small dog ear flap on the left side of the seed tube, turn constantly. They should gently turn sporadically, especially through areas of thick residue.

Closing Wheel System

Consider an alternative to rubber closing wheels. For cool, moist planting conditions, take a look at running one spike wheel (15 inches) and one rubber wheel (13 inches). The spike wheel can help chop the sidewall improving fracturing and sealing in the tough soil conditions. For no-till, an even more aggressive approach may improve trench closing.

Closing Wheel Alignment

With your planter sitting on concrete, pull ahead about 5 feet (1.5m). Look at the mark left behind the planter by the double disk openers. The mark should run right down the centreline between closing wheels. If a closing wheel is running too close to the mark, adjust the closing wheels to bring it back to centre.

Row Cleaners

With higher levels of residue, almost any planter can benefit from well adjusted row cleaners. Row cleaners sweep residue from the row, warming the soil around the seed trench, reducing wicking and seedling blight. Make sure row cleaners gently sweep residue – you don’t want to move soil, just residue.

Get Organised

Have your crop field plans by hybrid/variety and populations organised; seed ready, planter monitors working/programed and machinery and equipment serviced and tuned up.
