The hydraulic reversible plough is one of the most vital, high-draft implements on your farm. Its performance hinges entirely on one critical factor: the match between the plough size and your tractor's Horsepower (HP). Get this wrong, and you'll face excessive fuel bills, slow work rates, and premature equipment failure. Get it right, and you’ll unlock maximum field efficiency.

Here is a practical guide to ensuring your tractor and your new reversible plough are the perfect fit.

Why the HP Match Matters More Than You Think

A tractor is most fuel-efficient when its engine runs under optimal load.

• Under-powering (Plough too Large for HP): The tractor labors, increasing wheel slippage, overheating, and spiking fuel consumption. You’ll be forced to drive slower and plough shallower, reducing productivity and wasting effort.

• Over-powering (Plough too Small for HP): The tractor is under-utilized. You burn fuel to run a large engine without fully engaging its potential, leading to high ownership costs and inefficient capital use.

The goal is to match the plough’s draft requirement to the tractor’s drawbar power for maximum acres worked per hour at the lowest possible cost.

The HP-to-Furrow Formula: The Starting Point

The simplest rule of thumb in ploughing is the amount of power required per furrow (bottom).

• General Rule: A safe estimate requires 20 to 30 HP per furrow, depending on soil conditions.

  • 2-Furrow Plough (2 Bottom): Ideal for tractors in the 40 HP to 60 HP range.

  • 3-Furrow Plough (3 Bottom): Ideal for tractors in the 60 HP to 85 HP range.

  • 4-Furrow Plough (4 Bottom): Requires 85 HP and above.

Always refer to the manufacturer’s specifications. For instance, a robustly built plough like the Shakti Balram Fix will clearly state the minimum and optimum HP for its design.

Adjusting for Soil and Depth: The Reality Check

The required HP doesn't just depend on the number of furrows; it’s heavily influenced by the ground you are working:

1. Soil Type:

• Light Soil (Sandy/Loamy): Use the lower end of the HP range (closer to 20 HP/furrow).

• Heavy Soil (Clay/Rocky): Use the upper end of the HP range (closer to 30 HP/furrow). Heavy clay, especially when wet, can dramatically increase the required pull force.

Working Depth: Deeper tillage requires substantially more HP. If your operation requires deep primary tillage (over 10-12 inches) to break hardpan, you must choose a larger HP tractor or opt for fewer furrows.

Tyre and Ballast: A high HP tractor cannot pull its maximum load if it lacks traction. Ensure your tyres are in good condition and the tractor is properly ballasted with wheel weights and/or fluid to maximize the transfer of power from the engine to the ground, minimizing wheel slip.

The Final Step: Always Consult Your Dealer

The figures above provide a solid guide, but the exact combination of plough model, furrow spacing, and your local soil type is best determined by an expert. Before making a final purchase, always consult the equipment dealer. They can analyze your specific tractor model, field conditions, and farming requirements to ensure you get a plough that delivers peak performance year after year.
