Frequently Asked Questions (Offset Disc Harrow Botswana)

Question: When should I use an offset disc harrow instead of a disc plough?

Answer: A disc plough is used for primary tillage (breaking hard ground). The offset disc harrow is used for secondary tillage—breaking up the clods left by the plough, leveling the field, and burying crop residue to create a smooth, plantable seedbed.

Question: What is the best harrow size for an 85HP 4WD tractor in Botswana?

Answer: For an 85HP 4WD tractor like the MF 385, a 20-disc or 24-disc offset harrow is ideal. The 4WD system provides the necessary traction to pull these heavier harrows through deep soil for maximum aeration.

Question: Does the offset disc harrow work well in sandy Botswana soils?

Answer: Yes. In sandy soils (loam), the harrow works efficiently as an all-in-one tool for controlling weeds and mixing the top layer of soil without destroying the soil structure, which helps in better moisture retention.

Question: Can I use this implement for primary tillage on soft land?

Answer: While it is primarily a secondary tillage tool, a heavy-duty offset disc harrow can be used for shallow primary tillage on previously cultivated or softer soils, saving you the time and fuel required for a full ploughing cycle.

Question: How do I maintain the bearings on my disc harrow?

Answer: Our harrows feature greaseable, heavy-duty tapered roller bearings. To ensure longevity in Botswana’s dusty conditions, we recommend greasing the bearings every 8–10 working hours and checking for any loose arbor bolts.
