Seed Grader
The Supreme seed grader cleans seed and sorts it by size across a series of interchangeable screens. Manufactured in Faisalabad by Supreme Agri Implements, it removes chaff, dust, weed seed and the small shrivelled fraction that would otherwise be planted or sold alongside good grain.

What does a seed grader do?
Seed straight from a thresher is a mixture. Alongside the grain you want are broken kernels, chaff, dust, soil, weed seed and a fraction of small, poorly filled grains. Planting that mixture means planting the weak fraction too, and those seeds germinate poorly or produce weak seedlings that never catch up.
A grader separates by size using stacked screens: material too large stays on top, material too small falls through, and the target fraction is retained. Changing screens changes the size bands, so the same machine handles wheat, rice, pulses and other crops.
The gain shows up in two places. Graded seed germinates more uniformly and meters far more accurately through a seed drill, because the metering mechanism is handling consistently sized grain rather than a mixture. And grain sold for consumption attracts a better price when it arrives clean and uniform rather than full of chaff and dust.

- Screen selection is the whole job — pick sizes that match your crop and target grade.
- Grade seed before storage, not after; clean seed stores better and attracts fewer insects.
- Removing weed seed at grading prevents planting next season's weed problem with the crop.
