WILLIAMES SEEDING LINE

The Williames Seeding Line is an integrated coordinated system to optimise seed-sowing outcomes and reduce time and labour by cutting the multiple handling of trays.
This was developed in response to our customers need for an integrated, automated way to produce seedlings. Vermiculite Covering and Watering can be achieved on a timely, highly accurate and efficient basis. Other options include mounting a Williames Mixer over the Williames Universal Filler or feeding the Williames Universal Filler with a Soil Elevator, or using the larger Williames FNC Filler and Williames Soil Accelerator.

The Line is a fully proven integrated system. Williames products are robustly constructed, simple to operate and reliable with low maintenance costs and high productivity.
Integrated electrical wiring and controls enable operation and control from a single point near the seeding head.
Williames has 4 models of seeding lines, running in capacity from 750 trays an hour all the way through to 2500 trays an hour – the fastest seeding line in the world.
This Consists of:
- Tray De-Stacker
- Universal Filler
- Cleated Conveyor
- Seeder w/ Drums
- Vermiculite Coverer
- Watering Tunnel
