About Tractor Seat Springs

A tractor seat spring carries the vibration and shock reaching the driver. Over long hours in the field the seat is not about comfort but health: once the spring fatigues, the shock passes straight into the back. That makes the seat spring one of the parts that affects the operator most, even though it never stops the machine.

This is a compression spring, and in a compression spring failure begins not with breakage but with a loss of free length. A spring working above the permissible stress settles a little on every cycle; its force drops and the seat gradually sinks. If the seat no longer rises as it used to, the spring has lost its length — there is no need to look for a broken part in the mechanism.

Production is based on the wire diameter, outside diameter, free length and coil count of the original part, and the spring fits without modification to the seat. On bellows type seats the installation length differs, so those are produced as a separate item.

Our catalogue covers seat springs for New Holland, John Deere Grammer, John Deere 5M series, Massey Ferguson and Landini bellows type, STEYR, Tümosan and SAME series, together with a standard slim type.

How it is made

Every step after coiling happens in our own plant; nothing is outsourced. This shortens lead times and keeps quality responsibility in one pair of hands.

01

CNC spring coiling

Formed in the 0.20–40 mm wire range.

02

Tempering

Stress is relieved and elasticity becomes permanent.

03

End grinding

Seating faces are flattened on compression springs.

04

Galvanizing

Surface protection against corrosion.

05

Packaging

Domestic and international logistics included.

FAQ

The seat bottoms out — should the spring be replaced?

Most likely yes. In a compression spring failure begins with loss of free length rather than breakage; if the seat no longer rises as it used to, the spring has lost force. Comparing it with a new spring, or measuring an equivalent spring on the same tractor, is a quick check.

Which tractor brands do you produce for?

Our catalogue covers New Holland, John Deere (Grammer and 5M series), Massey Ferguson, Landini, STEYR, Tümosan and SAME series. For models not listed we produce from a sample or from dimensions.

What is the difference between bellows type and standard type?

On bellows seats the installation length of the suspension group differs, so the spring is produced as a separate item. Simply state whether the seat is a bellows type when ordering.

I do not know the brand — can I order by dimensions?

Yes. Given wire diameter, outside diameter, free length and coil count, brand information is not needed. If you do not have those values, a photograph of the old spring next to a ruler will do.

Would a stiffer spring improve comfort?

No, it does the opposite. An over-stiff spring transmits the shock instead of absorbing it. Staying close to the original force gives the right result.

How often does a seat spring need replacing?

It depends on working hours and ground conditions. The criterion is condition, not time: once free length has shortened or the seat starts bottoming out, it is time to replace it.

Other machine groups

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.
