Draught Animal Power & Pull, hp & Area Worked
Powers bullocks
Enter draft pull, working speed and implement width to get power in watts and horsepower, the area worked per day and the distance — for bullocks, buffaloes, horses and camels.
Size your draught power
Next: expect about 0.7 hp sustained; with a 0.2 m implement over 6 h you cover roughly 1 acre/day.
Animals sustain ~10% of body weight as draught for limited hours; rest, terrain and soil resistance all reduce real output below the ideal figure.

Turn pull and pace into a day's work done
Bullocks, buffaloes, horses and camels still do real field work, and their output comes down to simple physics: power equals the draft pull they exert times the speed they move. A pair typically delivers about one horsepower of steady, sustainable work — enough to plough — while a single animal handles lighter jobs like carting or a water lift. From the pull, speed and implement width you get the area a team can work in a day, which is what really matters when you plan the season.
This tool gives the power in watts and horsepower, the area worked per day and the distance covered from your draft pull, working speed and implement width. Rest, feeding and good harnessing decide whether the animals hold that output all day, so size the team to sustainable power, not a brief peak. Pair it with the Field Capacity and Animal Weight tools to plan the work and keep the animals in condition.

Frequently Asked Questions
How is draught animal power calculated?+
Power = draft pull (force) × speed. So an animal pulling with 600 newtons of force at 1 metre per second delivers 600 watts. Divide watts by about 746 to get horsepower. From the pull, the working speed and the implement width, you can also work out the area covered in a day's work.
How much power does a draught animal give?+
A single working animal sustains roughly a tenth to a fifth of a horsepower in continuous field work, and a pair of bullocks or buffaloes together typically delivers about one horsepower sustainably. They can pull much harder in short bursts, but the figure that matters for a day's ploughing is the steady, sustainable output, not the peak.
What is draft pull?+
Draft pull is the horizontal force the animal exerts on the implement — measured in newtons or kilograms-force — to drag a plough, cart or harrow through soil or along a road. It depends on the implement, the soil and the load. Power comes from this pull multiplied by how fast the animal moves, so both matter.
How is the area worked per day calculated?+
Area worked = working speed × implement width × working time, adjusted for a field-efficiency factor. A wider implement and a faster, longer working pass cover more ground, while turning, rest and slippage cut into it. The tool combines speed, width and time so you can see how much land a pair can realistically plough or harrow in a day.
Why does a pair give about one horsepower?+
Two animals working together share the load and can each sustain their portion without exhausting, and a well-matched pair pulling in step delivers around one horsepower of useful, continuous output — which is why bullock and buffalo pairs are the traditional unit for ploughing. Single animals are used for lighter work like carting or operating a water lift.
What affects a draught animal's output?+
Rest, feeding, the heat of the day, body weight and condition, and how well the harness fits all change how much an animal can deliver. A tired, underfed or badly harnessed animal pulls less and for less time. Working in the cool of the morning, feeding well and using a good harness keep the sustainable power and the area worked up.
Does it work for buffaloes, horses and camels too?+
Yes — the power = pull × speed relationship is universal, so it applies to bullocks, buffaloes, horses and camels alike. Heavier, stronger animals and faster walkers give more power; just enter the draft pull and speed that suit your animal and the calculator does the rest.
What units does the calculator use?+
Enter pull as a force (newtons or kilograms-force), speed as distance per time, and implement width as a length; the tool returns power in both watts and horsepower, plus area worked per day and distance covered. Using consistent units keeps the power and area figures correct.
Are the figures exact?+
They are sound planning figures. Real output depends on soil, slope, the animal's condition, harnessing and how long it works without tiring. Use the calculator to size the team and plan the day's work, then watch the animals and adjust — sustainable power is about not exhausting them, not hitting a peak.
Does it run privately in my browser?+
Yes. All the maths runs in your browser; nothing you enter is uploaded or stored anywhere. Change the pull, speed or width and the power, area worked and distance update instantly.
