AGRICULTURAL MACHINERY SPRING SOLUTIONS

Tines, baler teeth and cultivator springs for agricultural machinery.

Field springs take stone strikes, crop loads, mud and long storage. We make tines, baler teeth and pedal springs from your drawing, an original part or a worn sample.

Agricultural Machinery Spring Solutions spring application

Agricultural machines need springs that flex under crop and soil loads, survive impacts and return to shape season after season. We make harvester reel tines, baler tines, tillage tines, cultivator springs and tractor pedal springs to customer drawings or physical samples. Agriculture is the largest group in our published wire form and torsion application cases.

Key Takeaways

  • 16 of the 36 parts shown in our four application case images are agricultural, including reel tines, baler tines, tillage tines, cultivator springs and tractor pedal springs.
  • We can start from a drawing, a sketch or a physical sample, which suits replacement parts that have no drawing.
  • Wire diameters run from 0.1 mm to 80 mm, with no fixed minimum order quantity.

Which springs agricultural machinery uses and why

Harvester headers and pickups

Reel tines and pickup fingers lift and feed the crop. Each tine is a wire form whose coils act as a torsion spring: when the tip strikes the ground or a heavy clump, the coil lets it swing back, then returns it. Coil count, wire diameter, coil diameter and leg length set the stiffness. Our portfolio includes reel tines and finger springs, among them replacement tines compatible with Claas Lexion and Tucano headers.

Balers and forage harvesters

Baler pickup tines are usually double torsion springs: two coils joined by a loop that clamps to the tine bar. The coils and the bends where the wire leaves the coil, into the tine leg or the mounting loop, carry the highest stress, so bend radii are reviewed carefully. Our portfolio includes replacement baler tines compatible with McHale balers and compression springs for fodder harvesters. To measure a worn tine and specify a replacement, see our spring tines guide for balers, rakes and tedders.

Tillage equipment

Harrow, cultivator and subsoiler tines work inside the soil and take repeated shocks from stones. A coil that deflects and recovers protects the tine and the frame. Cultivator coil springs and extension springs hold working parts against the ground.

Tractor controls

Pedal return springs bring brake, clutch and accelerator pedals back to rest. They need steady force at the installed position and hooks or legs that match the pedal bracket. Examples include brake pedal springs suitable for Mahindra tractors and an accelerator foot spring suitable for Massey Ferguson tractors. The brand names only show which tractors these replacement springs fit.

Choosing material and finish for field conditions

Field springs meet water, mud, fertilizer and crop sap, then sit in storage between seasons. The choice balances fatigue strength against corrosion resistance.

Option Where it fits What to weigh
Oil-tempered wire Larger tines, cultivator springs Good fatigue strength; needs a finish outdoors
Carbon spring wire Pedal and extension springs Economical; relies on plating or coating
Silicon-chrome spring steel High-stress tines under shock Higher strength at the same wire size; higher cost
Stainless steel 304 / 316 Constant wet or corrosive contact Lower strength than spring steel at equal diameter, so geometry may change
Yellow or bright zinc Parts exposed to weather Yellow zinc is visible on the reel tine shown on this page
Black, red or blue coating Parts matching the original’s appearance Color confirmed at review

Electroplated high-strength spring steel is normally baked soon after plating to reduce the risk of hydrogen embrittlement, so the finish and any post-plating treatment are agreed at review.

What to send for an engineering review

For a replacement part with no drawing, a physical sample is enough to start. Otherwise send:

  • A drawing (DWG, DXF, STEP or PDF) or a photo (JPG or PNG) with key dimensions.
  • For a coil spring: wire diameter d, outside diameter D0 and free length L0 are enough to start.
  • For a tine: wire diameter, number of coils, wind direction, leg lengths, the angle between legs and the mounting eye size.
  • The machine and position where the part fits.
  • Load at the working position, if known, plus quantity and the records you need.

Lead time is confirmed at quotation, which helps when you plan stock ahead of harvest. See our six-stage process for what follows.

Frequently asked questions

Can you copy a worn tine if we have no drawing?

Yes. We can work from a physical sample, confirm manufacturability before quoting, and make prototype samples for fit and load approval before production.

Is there a minimum order for replacement tines?

There is no fixed MOQ. Small batches and high-volume runs are both supported; the practical quantity depends on spring type, tooling and material.

What records come with an order?

As agreed at project setup: inspection reports, material certificates, dimensional records and traceability. We hold ISO 9001 and IATF 16949 certification.

Send your drawing, photo or sample through our contact page and we will reply with engineering feedback or a quotation within 24 hours.

INDUSTRY REQUIREMENTS

A replacement tine has to fit, flex and spring back like the original.

We review wire diameter, coil count, hand of wind, leg angles and mounting geometry from your drawing or sample, and confirm manufacturability before we quote.

Impact and bending fatigue

Tines and teeth flex on every pass and take sudden hits from stones and crop lumps, so wire size, coil geometry and heat treatment are chosen together.

Mud, fertilizer and weather

Parts work wet and sit outdoors between seasons, so the finish is part of the specification, not an afterthought.

Drop-in fit on existing machines

Replacement springs must match mounting eyes, leg angles and wind direction so they bolt onto the header, baler or harrow without modification.

QUALITY EVIDENCE

Fit & Geometry Checks

Leg angles, coil diameter, tine length and mounting eye size are checked against the drawing or the approved sample.

Load at Working Position

Spring force or tine deflection load is measured at the positions agreed during the requirement review.

Finish & Lot Records

Material, finish and inspection results are recorded per lot as agreed, so a reorder before the next season matches the approved part.

COMMON QUESTIONS

Answers Before You Ask

Clear answers to common purchasing questions.

Still have questions?
Can you manufacture from my drawing without a standard part number?

Yes. Most of our projects start from a customer drawing or application sketch. We review the geometry, material and performance needs, then confirm manufacturability before quoting.

What is your minimum order quantity?

We support both small-batch prototypes and high-volume production. There is no fixed MOQ — quantities are evaluated based on the spring type, tooling and material requirements.

How do you handle springs for high-temperature or corrosive environments?

We select materials (such as Inconel, stainless steel or special alloys) and surface treatments matched to the operating environment. Our engineers can recommend options based on temperature range, media exposure and cycle life.

What documentation can you provide with production orders?

We supply inspection reports, material certificates, dimensional records and traceability documentation as agreed during project setup. PPAP and FAIR packages are available for automotive and aerospace programs.

What is the expected lead time?

Lead time depends on the spring type, material, tooling, quantity and approval requirements. We confirm the production and sample schedule during quotation.

How are payment and delivery terms confirmed?

Commercial terms, delivery address and documentation requirements are confirmed with the quotation before production starts.

What support is available after delivery?

After-delivery questions can be routed through the project contact for drawing questions, quality documents, repeat orders and application feedback.

Can you provide samples before mass production?

Yes. Prototype and pre-production samples can be arranged for dimensional, load and application approval before the full production order proceeds.
