Pick your seeder

All three push seeders take the same rollers and gears, so the setups in the roller finder work on every one. The difference is how many rows you can sow in a single pass, and on the multi row seeders you can sow fewer at any time by leaving a hopper off.

Seed rollers are sold separately. Not sure which you need? Use the roller finder or start with the Market Garden Roller Kit.

Larger setups, made to order

Engine powered and tractor mounted Jang seeders for bigger plots and field scale sowing. These are ordered in for you, so email us first and we will confirm lead times and help you spec the right setup.

Fittings for the bar mounted seeders: JPH bar 1.5m, JPH bar 3m and 3 point hitch (Cat 2).
