About second-hand Keulmac machines

Keulmac is a small-scale Dutch manufacturer of agricultural machinery in Ens, in the province of Flevoland. The company focuses primarily on onion harvesters, onion haulm toppers, crate tippers and custom transport vehicles.

Besides the production of their own machines, Keulmac also sells a wide range of new and used machinery produced by other manufacturers. The name Keulmac is a contraction of the owner’s surname (Van Keulen) and the word machines.

Keulmac onion harvesters

Keulmac manufactures its own line of harvesting machines for onions and shallots. These onion harvesters are renowned for their stable and sturdy construction. A square harvesting shaft loosens the onions from the soil and lifts them onto a harvesting mat, while an intake paddle prevents them from rolling back onto the ground. Next, a sieving web is used to remove any loose bits of soil. The harvesters puts the onions on a windrow, so, after drying, they can easily by lifted by an onion loader.

Keulmac onion haulm toppers

Over the years the most conventional method of harvesting onions has become a haulm topper - a device for cutting the green tops off onions - mounted to the front of a tractor and a harvester at the rear of the tractor. This enables onions to be harvested and topped in one pass. Many onion growers, however, still use trailed rear-toppers when they don't have a PTO in front of the tractor.

Keulmac makes onion harvesters as well as toppers in the following widths: 150cm, 180cm, 200cm and 225cm.

Keulmac box / crate tippers

The construction of Keulmac crate tippers is simple, yet efficient. The tippers can be used to tip wooden and plastic crates in a variety of sizes and can be used in processing lines for vegetables, soil or flower bulbs.

We will be happy to advise you about which machine is best suited for your products. You will find our current offering of used Keulmac machines here.
