Stem Cutter / Topper

Cut the tops off onion, garlic, and potato rows ahead of harvest so the lifter runs clean and the crop cures faster. A simple V-belt drive and open covers make field service quick and easy.

Why top first

Clean tops, faster harvest

Leaf tops are what clog the lifter and what slows the cure. Cutting them ahead of harvest turns a stop-start operation into a continuous pass — and the bulbs go into storage in better condition.

Tops ahead of the lifter

Removes onion and garlic leaf tops before harvest so the lifter feeds clean and doesn’t clog.

Faster curing

With tops cut back, bulbs cure faster in the field and store better after pickup.

Even, uniform cut

A single pass tops the rows at a consistent height across the bed.

Pairs with the harvester

Runs ahead of the onion harvester to complete the lift-to-cure workflow in fewer steps.

Built for the field

Built to be fixed in the field

  • 01

    V-belt drive

    The belt slips before the steel breaks. When something goes into the rotor, the bill is a belt — not a gearbox.

  • 02

    Open covers

    The drive is reachable without stripping the machine down. Belt change happens at the headland, not in the shop.

  • 03

    PTO-driven

    No engine of its own — no separate fuel, and no second maintenance schedule to keep track of.

  • 04

    Built in Iksan

    Out of the same ISO 9001 / 14001 certified plant that builds the WECAN GLOBAL tillage range.
