A rotavator is one of the hardest-working machines on a Punjab farm. When something is off, you see it straight away in the field: clods left behind, blades wearing out too fast, straw wrapping round the rotor, or the tractor struggling to pull. The good news is that most of these problems come from a handful of causes, and almost all of them can be fixed in the field.<\/p>\n\n\n\n

This guide is organised by problem<\/strong>, so you can jump to what you are seeing. For the basics of how a rotavator works and how to choose one, read our Rotavator Guide<\/a>.<\/p>\n\n\n\n

Common problems, causes and fixes<\/h2>\n\n\n\n
\n\n
1. Big clods left behind<\/div>

Likely cause:<\/strong> driving too fast, soil too dry and hard, or blades worn short.<\/p>

Fix:<\/strong> drop to a lower gear so the blades take more cuts per metre. Work when the soil has some moisture. Check the blades and replace them if they have worn down.<\/p><\/div><\/div>\n\n

2. Soil turned to fine powder<\/div>

Likely cause:<\/strong> driving too slowly or making too many passes over dry soil.<\/p>

Fix:<\/strong> go a gear higher and avoid unnecessary passes. Over-pulverised soil crusts after rain or irrigation and wastes diesel.<\/p><\/div><\/div>\n\n

3. Straw wrapping round the rotor<\/div>

Likely cause:<\/strong> long, wet straw or heavy residue lying in heaps.<\/p>

Fix:<\/strong> spread the straw evenly and let it dry a little before working. Stop, switch off the PTO and engine, and clear the wrapped straw before it strains the drive. Never clear it with the PTO running.<\/p><\/div><\/div>\n\n

4. Blades wearing out too fast<\/div>

Likely cause:<\/strong> stony or very dry soil, working too deep, or loose blade bolts letting blades rock.<\/p>

Fix:<\/strong> raise the depth skids a little, work at better moisture, and keep blade bolts tight. When blades are worn, replace the full set so the rotor stays balanced.<\/p><\/div><\/div>\n\n

5. Uneven depth across the width<\/div>

Likely cause:<\/strong> the rotavator is not level on the three-point linkage, or the two depth skids are set differently.<\/p>

Fix:<\/strong> level the machine side to side with the linkage adjuster, and set both skids to the same height.<\/p><\/div><\/div>\n\n

6. Tractor struggling and black smoke<\/div>

Likely cause:<\/strong> working too deep, too fast a gear, or a rotavator too wide for the tractor.<\/p>

Fix:<\/strong> reduce depth and use a lower gear. The Rattan rotavator suits tractors of 35 HP and above, and wider models need more power, so match the width to your tractor.<\/p><\/div><\/div>\n\n

7. Gearbox running hot or noisy<\/div>

Likely cause:<\/strong> low or old gearbox oil, or the machine being overloaded for long periods.<\/p>

Fix:<\/strong> check the oil level and top up with the grade in the manual; change old oil. If the noise continues, stop using it and get it checked before it damages the gears.<\/p><\/div><\/div>\n\n

8. Heavy vibration<\/div>

Likely cause:<\/strong> a missing, bent or broken blade, or a mix of old and new blades.<\/p>

Fix:<\/strong> stop and inspect the rotor. Replace damaged blades and fit them in the correct pattern so the rotor stays balanced.<\/p><\/div><\/div>\n\n

9. Soil sticking to blades and smearing<\/div>

Likely cause:<\/strong> the field is too wet.<\/p>

Fix:<\/strong> wait for the soil to dry. Working wet soil makes a hard layer under the surface that blocks roots and water.<\/p><\/div><\/div>\n\n

10. Rough, ridged finish<\/div>

Likely cause:<\/strong> the rear levelling board is set too high or its springs are slack.<\/p>

Fix:<\/strong> adjust the board so it rests lightly on the soil and smooths the surface behind the rotor.<\/p><\/div><\/div>\n\n<\/div>\n\n\n\n

Setting the depth correctly<\/h2>\n\n\n\n

The side drive cover and the depth skid. Set both skids to the same height.<\/figcaption><\/figure>\n\n\n\n

Many of the problems above come back to depth. The Rattan rotavator has an adjustable depth skid<\/strong> on each side. Set both skids to the same height before you start, work a short strip, then check the depth with a stick at a few points. Deeper is not always better: working too deep uses more diesel, wears blades faster and puts more load on the gearbox.<\/p>\n\n\n\n
