Pneumatic or battery olive harvester: what really changes, with 2026 figures

The question comes back every autumn, but this year the answer is different from twelve months ago. Not because the tools have changed: what has changed is how much it costs to keep an engine running.

Running an engine has never cost this much

A pneumatic system needs a compressor, and the compressor needs an engine that runs: petrol, or the tractor's power take-off. As long as diesel stayed below one euro, that line could almost be ignored.

Not any more. At the end of September 2026 subsidised agricultural diesel is running at around €1.65 per litre, with quotations between 1.60 and 1.80 depending on supplier and area. In March of the same year it was €0.85: it has almost doubled in six months. At the pump, self-service petrol is above €2 and diesel above €2.24.

Since 2 October one large supplier has offered a 20% discount on the pre-VAT price of agricultural fuels, and that claws something back. But the order of magnitude does not change: the same harvesting day that cost a hundred euros in fuel last year costs almost double this year, and it happens in the very year the price of oil has halved — we covered that in the figures this campaign starts from.

A battery-powered olive harvester simply does not have that cost. It is not a marketing detail: it is a line that disappears from the accounts, every day, for the whole campaign.

What it costs to get started

Here the comparison is simple, because these are two price lists.

A pneumatic kit for two operators — engine, compressor, two harvesters and two poles — runs between €1,800 and €2,700. For three operators you go past €3,000. These are the public prices of dealers in October 2026.

On the battery side, two EVO 42 units cost €1,398, three cost €2,097. There is no engine, because none is needed.

	Pneumatic	Battery-powered
Two operators	€1,800 – €2,700	€1,398 (two EVO 42)
Three operators	over €3,000	€2,097 (three EVO 42)
Fuel	every working day	none
Hoses	€78 – €100 per 100 metres, to be replaced	none, or a 15 m cable included

The hoses deserve a line of their own, because nobody puts them in the quote. A hundred metres of 7.5 × 10 polyurethane costs between €78 and €100, fifty metres between €46 and €60. They get cut, punctured, caught in the branches: they are a consumable, not a one-off purchase.

What wears out, and what breaks

On a pneumatic harvester the part that gives way is almost always the same: seals and piston. It is a simple, cheap repair, and it is the reason people who have used air for twenty years say it lasts: you change the seals and carry on.

There are two things, though, that sellers do not talk about willingly.

The first is that the bushings in the piston housing wear out and the tool loses striking force. It is a fault that does not stop you: it keeps beating, only more slowly, and you notice it from the fruit left on the tree rather than from the tool in your hand.

The second concerns the cold, and it is the reason we are writing about this now. In plastic bodies the condensate from compressed air can freeze and jam the comb: it happens early in the morning, in November and December, which is exactly when the tool has to start. To limit it you need a condensate separator and an in-line lubricator, plus the specific pneumatic oil: they are not optional accessories, they are part of the system, to be bought and maintained.

And the compressor has a schedule of its own: drain the condensate at the end of every working day, check the levels before every use, check the pump oil at around 300 hours and change it at about 500, clean the air filter, check the belt and the fixings, and the spark plug. It is a second machine to keep alive, on top of the tool in your hands.

On the battery-powered tool what breaks are the carbon rods: they snap when you force the comb into a thick branch, they cost little and you change them in the field with a screwdriver. The rest — motor and mechanics — asks two things: clean the head at the end of the day, and do not pull the tool when the comb is caught.

What changes in the field

Numbers aside, the differences customers describe when they move from air to battery are three, and none of them is about speed on a single branch.

• There is no hose any more. Nothing to get caught, nothing to unroll and roll up again at every move, no radius limit around the compressor.
• The tractor stays off. People who work with air are the first to say it: keeping an engine running next to you all day is tiring, before it is expensive. A pneumatic system is also noisier.
• Everything moves faster. With trees far apart, or ground you cannot drive across, setting the system up and taking it down weighs more than the harvesting itself.

Where air is still ahead

There is one thing air does better, and it is only fair to say it: three operators work off the same engine and nobody stops to change a battery. If you harvest with a crew for weeks on end, that advantage is real.

But it only goes so far. The EVO 42 ULTRA runs for sixteen hours on the 42V backpack, which is two full days. And a single 100 Ah car battery powers two EVO 42 units at once. The engine, meanwhile, stays off all day.

Cable or backpack: how to choose

Once it is clear that the battery wins on running costs, the real choice remains, and it is not between brands but between two ways of carrying the power.

The EVO 42 (€699) runs off a 15-metre cable, which can be extended, connected to a car battery through an inverter: 8-10 hours of runtime, 1,400 beats per minute, 2.8 kg in the hand and a telescopic pole from 240 to 350 cm. It is the right choice when the car or the tractor can stay close to the trees — and one 100 Ah battery powers two of them.

The EVO 42 ULTRA (€1,299) has the same motor but a 42V battery backpack: no cable, sixteen hours, about 5 kg on your shoulders. You need it when the trees are far apart, when the ground cannot be driven across, or when you harvest for third parties.

There is also a third route few people know about: the backpack battery can be bought on its own and fitted to an EVO 42 already in use. If you start with the cable and find it limiting, you do not have to buy the tool again.

In short

• The comparison is not between two tools, it is between a system with an engine to feed and one without.
• Agricultural diesel has almost doubled in six months: this year that line weighs twice what it did last year.
• For two operators the battery tool costs less to buy (€1,398 against €1,800-2,700) and consumes nothing.
• On the pneumatic tool seals and bushings wear out, and the condensate freezes on exactly those November mornings. Plus the compressor's maintenance schedule.
• Air stays ahead on one thing only: three operators on the same engine. The sixteen-hour backpack and the car battery that powers two tools cover that case.
• Cable if the car can get close to the trees, backpack if the ground is wide or you work for third parties. The backpack can be added later too.

A note on honesty: the fuel and kit costs are public figures from October 2026, the faults are the ones our customers describe to us and the ones you read in olive growers' forums. We have not measured the consumption of a pneumatic system in a laboratory, and we do not put down numbers we do not have.
