Jo

Compact tracked electric crawler for narrow, fragmented and hard-to-reach vineyard and nursery plots — GNSS RTK-guided tool carrier for mechanical inter-vine weeding. No longer manufactured, sold or supported by Naïo SAS as of 15 June 2026, following the company's 2025-26 judicial restructuring (Naïo itself survived under new ownership, but the Jo and Orio product lines were dropped).

At a glance

Best for

Historical reference only — was best suited to narrow (68 cm), steep or fragmented vineyard and tree-nursery plots too tight or awkward for a straddle tractor.

Avoid if

You are looking to buy, lease or get support for a Jo unit today — production and support ended 15 June 2026; there is no dealer, parts or software channel left.

Not suitable for

Any current purchase decision; wide-row vineyards or open-field/broadacre crops — Jo was built for narrow rows and tight, hard-to-reach plots, not wide spacing.
