Choosing blades? Start with our complete rotavator blade guide — L vs C vs J vs straight, steel and hardness compared.
When the paddy harvest ends, there is very little time to sow wheat. A super seeder that stops for missing blades in that window costs real money. The most common ordering mistake is simple: the buyer does not know exactly how many blades are in the super seeder set, or how many left-hand and right-hand blades it needs. This guide shows you how to count your set, plan spares and order the right blades the first time.
If you are new to blade shapes and steel, our super seeder blades buying guide covers the basics. Here we focus only on counting and planning the set.
Why the blade count matters
A super seeder rotor chops and mixes paddy straw into the soil while the seed drill places wheat behind it. Every blade has a job. If you fit fewer blades than the rotor is designed for, you leave strips of uncut straw, the seed sits on trash and germination suffers. If you guess the count and order too few, the machine waits. If you order the wrong mix of left- and right-hand blades, the set cannot be fitted in the correct pattern.
How to count the blades on your super seeder
You do not need the manual to get a reliable number. With the engine off, the PTO disengaged and the machine resting safely on the ground or stands, follow these steps:
- Count the flanges. These are the round plates welded along the rotor shaft that hold the blades.
- Count the blades on one flange. Most flanges carry the same number, but check the end flanges too, because some designs differ at the ends.
- Multiply. Flanges × blades per flange gives the total set. Example: 9 flanges × 6 blades = 54 blades.
- Split left and right. Look at which way each blade bends. Note how many bend left and how many bend right. In most rotors the split is equal, but write down the real figure from your machine.
- Count the bolts. Each blade usually needs its own bolt and nut set. Our blade bolts guide explains grade and replacement.
Write the figures on a card and keep a photo of it on your phone. It saves time every season.
Why one width can have different counts
Two super seeders of the same working width can carry different numbers of blades. Makers change flange spacing, the number of blades per flange and the blade length to suit straw load and tractor power. That is why a catalogue figure for "an 8-foot super seeder" is only a starting point. The rotor in front of you is the only number that counts. The same logic applies to rotavators, as we explain in how many blades are in a rotavator.
Is a super seeder blade the same as a rotavator blade?
Sometimes the shape looks close, but you should not assume it fits. Super seeder blades work in wet, heavy straw and often differ in length, bend angle, thickness or hole spacing. A blade that is a few millimetres off can rub the cover, leave gaps or load the bolts unevenly. Before ordering, measure an old blade using our guide on how to measure blades before you order, or simply send us a clear photo with a tape measure beside it.
Planning spares for the paddy-stubble window
The sowing window after paddy is short, and every dealer gets busy at the same time. Plan your blade stock before harvest starts:
- Owner-operators: check blade length and edges a few weeks before harvest. If the set is worn, order the full replacement set early and keep the old set's best blades as emergency spares.
- Custom-hiring operators: machines run long hours across many fields. Keep a complete spare set per machine, plus loose left- and right-hand blades and bolts for stone damage.
- Dealers: stock full sets for the super seeder models common in your area, not only loose blades. Our wheat–paddy blade stocking calendar shows when demand peaks.
Full set or single blades?
When the whole set has worn evenly, change it together. New blades fitted next to short, worn blades take more load, unbalance the rotor and mix straw unevenly. Single-blade replacement makes sense only when a few blades are broken or bent by stones and the rest are still near full length. If you are unsure whether your set is finished, read when to replace rotavator blades and compare your blades with a new one.
Fitting the new set
A correct count is only half the job. Fit every blade so its cutting edge meets the soil first, follow the left-right pattern on each flange, tighten bolts to the torque in your manual and recheck them after the first hour. Our step-by-step guide on how to fit rotavator blades applies to super seeder rotors as well.
What to send when you order
- Machine brand and model, and working width.
- Number of flanges and blades per flange.
- Left-hand and right-hand count.
- A photo of one old blade with a tape measure next to it.
- Whether you also need bolts and nuts.
With these details, we can match the blade and pack the exact set, so it arrives ready to fit.
Frequently asked questions
How many blades are there in a super seeder?
It depends on the model and working width. Count the flanges on the rotor and the blades fitted on one flange, then multiply. For example, a rotor with 9 flanges and 6 blades per flange takes 54 blades. Always confirm the figure from your own rotor or the maker's manual before ordering.
Is a super seeder blade set the same as a rotavator blade set?
Not always. Super seeder rotors work through heavy paddy straw and often use a different blade shape, length or hole pattern from a plain rotavator. Even when the count looks similar, check the blade drawing or send an old blade before you order.
Should I replace all super seeder blades at once?
When the set is evenly worn, yes. Mixing new and worn blades makes the rotor run out of balance and leaves uneven straw mixing. Replace single blades only when a few are broken or bent by stones and the rest are still close to full length.
How many spare super seeder blades should I keep for the season?
Many operators keep a full set ready before the paddy-stubble window, plus a small number of loose left- and right-hand blades and bolts for breakages. Custom-hiring operators who run long hours usually keep more, because a stopped machine in the sowing window costs more than the spares.
How do I order the correct super seeder blade set?
Share the machine brand and model, the number of flanges, blades per flange, and a photo of one old blade with a tape measure next to it. Include the left- and right-hand split. With that, the manufacturer can match the blade and pack the exact set.
