The Hamilton line of seeders have had a worldwide presence since 1979. They have a seeder for all greenhouse sizes — from the small to the larger grower. Their drum seeder is a much desired and sought after machine for mid to large operations.

Handy Seeder

The Hamilton Handy Seeder is designed for the grower who wants to get started sowing their own plugs, but does not want the expense of an automatic seeder. For small greenhouses or growers.

Drum Seeder

This machine is for the Commercial or larger growers. Or plug producers. Typical sowing rates for a plug tray would be around 700 trays per hour, or 300,000 seeds per hour.  Direct sowing into bedding plant packs is also possible at even higher rates.  Variable speed is a standard feature. One of the major advantages of the Hamilton Drum Seeder is that it will sow into virtually any plug tray, seed flat or bedding plant container on the market today.  With the additional new MEGA seeder kit for larger seeds, we can seed almost any seed using this seeder.

The Hamilton Natural Seeder

The Hamilton Natural Seeder is the industry standard seeder, and the machine by which all others are judged.  Ideal for the small to medium sized greenhouse operation, this machine delivers the versatility and accuracy you need and expect.  There are three methods for indexing the tray under the seeder head:

SYSTEM 1:

This entry-level model utilises the same precision seeder used on some of our more expensive seeding lines but fitted with a hand operated mechanism to step plug trays line-by-line under the seeder. Trays are loaded in the front of the machine, and then indexed out by a hand ratchet system. The seeder is synchronised to the ratchet mechanism to seed into each line of the plug tray. This machine only requires a compressed air supply.

SYSTEM 2:

This model has a mechanism to index the plug tray etc. under the seeder for precise sowing of seeds. The mechanism is powered by compressed air and controlled by a microprocessor PLC to synchronise it with the seeder. In operation, the growing container is loaded under the front of the seeder. A microswitch starts the cycle, and the mechanism pushes the tray forward a row at a time, seeding each time until the tray, fully seeded, is re-presented to the operator, when the mechanism stops ready for the next tray.  Dwell control and Multi-sow are now standard features (see below). A domestic single-phase electrical supply is required for this model.

SYSTEM 3:

This is the top-of-the-line Natural Seeder model, the fastest and most versatile of our Natural Seeder systems. The Seeder and Coverer are controlled by a microprocessor PLC to synchronise the tray with the Seeder. Set-up times when changing trays are exceptionally fast, and this model will sow all types of tray from plug trays to thin plastic flats and packs. The height of the conveyor is adjustable to match up with most proprietary filling and watering lines. Another bonus with this model is the multiple sow feature which can be set to sow 1, 2 or 3 seeds per cell before the conveyor advances to the next line. A Dwell function is also incorporated. As with all models variable speed is standard. A domestic single-phase electrical supply is also required for this model.
