Super Seeder Setup Guide: Settings, Field Prep, Maintenance and Common Mistakes

A super seeder can sow wheat straight into paddy stubble in a single pass, but only when it is set up properly. Most of the problems farmers face in the field (patchy germination, seed going too deep, the rotor choking on straw, blades wearing out early) come down to a few things missed before the tractor ever enters the field.

This guide walks through the setup, the settings, how to drive it, how to look after it, and the common mistakes to avoid. If you are new to the machine, start with our earlier article, Super Seeder: Sow Wheat Straight Into Paddy Stubble, Without Burning.

1. Prepare the field before sowing

Spread the straw evenly. The super seeder handles loose straw well, but thick heaps left behind the combine choke the rotor and leave bare patches where seed never reaches the soil. A combine fitted with a Super Straw Management System (SMS) spreads the straw evenly behind it. If your field was cut without one, scatter the windrows before you sow.

Get the moisture right. The soil should be moist but not wet. If it sticks to your boots and smears, it is too wet: the blades will plaster the soil and the seed tubes can block. If it is dry and hard, germination suffers. Many farmers time sowing a few days after paddy harvest, or give a light irrigation beforehand if the field has dried out.

2. Check the machine

• Blades: look for bent, cracked or badly worn blades, and make sure none is missing.
• Bolts: tighten the blade bolts and the frame bolts. A loose blade at rotor speed can do real damage.
• Gearbox oil: check the level and top up with the grade given in the manual.
• Grease: grease every nipple, including the PTO shaft joints and bearings.
• Seed tubes: run a hand through each tube and clear any old seed, mud or dust.
• PTO shaft: check the guard is in place and the shaft length suits your tractor.

3. Set the seed rate and sowing depth

The Rattan Super Seeder has an adjustable seed rate and sowing depth. Do not trust the setting on the scale alone. Seed size changes from variety to variety and lot to lot, so the same setting can drop a different amount of seed. Calibrate it yourself before you go to the field.

What seed rate should you use? It depends on the variety, the sowing date and your soil. Follow the current recommendation from Punjab Agricultural University (PAU) or your local agriculture department for the variety you are sowing. Late sowing usually needs a higher rate.

Sowing depth: wheat is normally sown shallow, a few centimetres deep, where it gets moisture but can still emerge easily. Seed placed too deep comes up weak and late; seed left too shallow, or on top of straw, may not germinate at all. Set the depth, sow a short strip, then dig in at a few spots to check where the seed actually landed.

4. Driving it in the field

• Keep a slow, steady speed. The super seeder cuts, mixes and sows in one pass. Going too fast leaves straw unmixed and the seed placement uneven.
• Engage the PTO before you lower the machine, and let the rotor reach speed first.
• Lift before turning at the headland. Turning with the blades in the ground strains the machine and damages the blades.
• Check the seed tubes regularly, especially in damp patches. A blocked tube leaves an empty row you will only notice when the crop comes up.
• Watch the seed level in the box and refill before it runs low.
• Avoid overlaps and gaps between passes. Use a marker or a fixed reference on the tractor.

5. Maintenance during and after the season

Replace blades as a set. When the blades are worn, change the full set rather than a few at a time. Mixing old and new blades unbalances the rotor and gives uneven tilling across the width.
