4.5 mm Seed drill shoe compression spring
The 4.5 mm seed drill shoe compression spring is a steel spring working in the seed drill group, with a wire diameter of 4.5 mm. It is made to the dimensions of the original part.
Where it works
An opener shoe spring stops the shoe riding up as soil hardness changes. It is the element that holds sowing depth constant; when it fatigues, depth varies across the field.
On a seed drill the job of the spring is to hold sowing depth constant. The opener shoe spring stops the shoe riding up as soil hardness changes; the coverer spring presses the closing part down with a steady force.
Dimensions and ordering
Wire diameter is 4.5 mm. The other values needed to order are the body dimensions, the free length and the leg form; these can be taken from a photograph of the old part or from the machine make and model. If you have a sample, that is the most exact route.

How it is made
Coiling, tempering, end grinding, coating and packing all happen in our own plant in Biga; no step is outsourced. The coiling line works in the 0.20–40 mm wire range. Tempering after coiling is never skipped — a spring coiled without stress relief loses its free length in the first season.

Frequently asked questions
Can it be used in place of the original 4.5 mm seed drill shoe compression spring?
Yes. Production takes the wire diameter, body dimensions, winding direction and leg form of the original part exactly; it fits without modifying the machine.
Do you produce sizes other than 4.5 mm wire?
Yes. Our coiling line works in the 0.20–40 mm wire range with no tooling dependency. For a different wire diameter, body size or leg form, a sample or a set of dimensions is enough.
What coating options are available?
Galvanized coating against corrosion is applied as standard. For the rake and hay rake springs in our catalogue we also produce silver, gold and black coated versions.
What is the minimum order quantity?
Because it varies with quantity, size and coating we do not publish a single lower limit. Send your requirement through the quote form and price and lead time come back together.

Cannot find the spring you need?
We produce to your dimensions in the 0.20–40 mm wire range, with no tooling dependency. A sample, a technical drawing, or simply a photograph of the old spring is enough.
