Rotavator vs plough: what's the difference?
They both work the soil, but they do opposite things to it — one turns the ground over, the other breaks it down. Here's the difference between a rotavator and a plough, and which you need.
A rotavator and a plough are often spoken of as alternatives, but they do genuinely different things. A plough cuts and inverts the soil in furrows, burying surface growth and lifting fresh soil up. A rotavator chops and mixes the top layer into a fine tilth. One opens ground; the other refines it — which is why they're often used in sequence.
The plough
For breaking new, compacted or grassed-over ground, and for turning in manure or green residues. It works deep and leaves rough furrows that weather down. On a walking tractor a single-furrow plough is the tool for opening a plot that hasn't been cultivated.
The rotavator
For working ploughed or already-cultivated ground into a level, fine seedbed, and for routine bed preparation. It's faster and tidier than a plough on workable soil, but it can't break heavy, grassed-over ground from scratch the way a plough can.
Why not both?
This is the case for a two-wheel tractor. A plain tiller can only rotavate, but a walking tractor with enough weight pulls a plough and drives a rotary hoe — plough to open the ground, rotavate to refine it, all from one machine.
Machines for each job
Does both: rotary hoe and plough
BCS 740
A two-wheel tractor takes a rotary hoe to till and a single-furrow plough to turn ground — so you don't have to choose. The BCS 740 is the benchmark for a machine that ploughs new ground and rotavates the seedbed afterwards.
Best for: Serious allotment holders and smallholders.

Best for ploughing heavy ground
Grillo G 110
At 142 kg and 11.7 hp, this Grillo has the weight and traction to pull a plough through heavy or previously uncultivated soil, then swap to a rotary hoe to work it down. Mass is what makes walking-tractor ploughing actually work.
Best for: Heavy ground and pro market-garden tillage.

If you only need to till
Camon C13
If you're never going to plough — just turn and refine existing beds — a dedicated heavy rotavator is simpler and cheaper than a tractor-plus-implements. This 11.7 hp rear-tine machine is all the tillage most people need.
Best for: Contractors and smallholders breaking the toughest ground.

Frequently asked questions
What is the difference between a rotavator and a plough?
A plough cuts and inverts the soil in furrows, burying surface growth and bringing fresh soil up — it's for breaking new or heavy ground and turning in residues. A rotavator chops and mixes the top layer with rotating tines, creating a fine tilth. Ploughing opens ground; rotavating refines it. Many growers plough first, then rotavate the seedbed.
Should I plough or rotavate?
Plough to break new, compacted or grassed-over ground and to bury heavy surface growth; rotavate to work that ground down into a fine seedbed, or to cultivate beds that are already established. They're complementary more than competing — plough then rotavate is a common sequence for a new plot.
Can a two-wheel tractor pull a plough?
Yes — that's a key advantage of a walking tractor over a plain rotavator. With enough weight and traction (generally 100 kg+ and 8 hp+), a two-wheel tractor pulls a single-furrow plough, then swaps to a rotary hoe to till. A light tiller cannot plough.
Is ploughing bad for soil?
Like deep rotavating, repeated ploughing can disrupt soil structure and bring up weed seeds, which is why no-dig and reduced-tillage methods have grown popular. Used judiciously — to establish or reset a plot rather than every season — it remains a valuable tool, especially on heavy or newly broken ground.
