Cashew Harvesting Machine
Separating fruit from nut at the point of harvest.
Cashew harvesting is still overwhelmingly manual: the nut grows beneath the fleshy cashew apple, and when ripe the whole fruit-and-nut simply falls to the ground, where it is gathered by hand. No machine picks the crop from the tree. Where machinery does help is the tedious field step that follows collection — separating the nut from the cashew apple — and that is what this petrol-powered, movable field machine does, at a productivity of about 250 kg/h.
How cashews are actually harvested
Ripe cashews are not plucked so much as collected: nuts drop as they mature and are picked up from beneath the trees. Timing follows the dry season — see the harvest calendar and cashew before harvest for the signs of readiness. Handlers wear gloves, because the cashew apple and shell carry a caustic oil (CNSL) that irritates skin. Careful hand collection lets pickers select ripe, sound nuts and leave immature or damaged ones — a quality advantage machines struggle to match.
Where a machine helps: nut-and-apple separation
Once the fruit is gathered, the nut has to be parted from the apple. Done by hand this is slow and messy; a field separator mechanises it, feeding the fruit through a mechanism that frees the nut without bruising the kernel. The nuts then move on to drying and processing, while the apple can be used locally for juice or other products. This is the same job covered in more depth on the cashew fruit separator page.
The field machine
Built around a petrol engine and sized to move around the orchard (about 1200 × 800 × 1350 mm), the machine takes the hardest manual step off the crew at roughly 250 kg/h.

What a machine can and can’t do
| Step | Method today |
|---|---|
| Picking from the tree | Manual — nuts fall and are collected |
| Nut-from-apple separation | Mechanised (this machine) or manual |
| Cleaning & drying | Sun or mechanical drying |
| Shelling & peeling | Cutting, shelling, peeling machines |
Fully mechanised tree harvesting isn’t standard in the industry — the tree and its fruit don’t suit it — so the practical gain is at separation and downstream processing. Tell us your orchard size and volume and we’ll advise what’s worth mechanising; contact us.
Frequently asked questions
How are cashews harvested?
Almost entirely by hand. The nut hangs beneath the fleshy cashew apple, and when ripe the whole fruit-and-nut drops to the ground, where workers gather it. There is no machine that picks the crop from the tree.
Is there a machine that harvests cashew nuts?
Not a true tree-harvester. What machinery helps with is the field step after collection — separating the nut from the cashew apple — which is what this petrol-powered, movable field machine does at about 250 kg/h.
What does the cashew harvesting machine do?
It mechanises the separation of the nut from the cashew apple in the field, replacing slow hand separation. It runs on a petrol engine and is built to move easily around the orchard, at a productivity of roughly 250 kg/h.
When are cashews harvested?
In the dry season, when nuts ripen and fall — broadly February to May in India and West Africa and later in East Africa. The exact window varies by country and climate.
