Coverage arithmetic

Total kit length has to equal or exceed the moldboard, and the sections have to land so the joints do not sit in the wheel tracks.

Section lengths and total coverage

Work out the number of sections from the moldboard width and the standard lengths available, then check the joints against where the wheels run. A joint in the wheel track wears fastest and clears least, so moving it a few inches is worth doing at the ordering stage.

What to write in the order

Geometry, ice condition, carbide grade, section count and inspection. Five items, and the kit arrives as specified.

Tolerances and inspection

Section length tolerance, hole position and the inspection that confirms them. On a multi-section kit the accumulation of small errors is what stops the sections aligning, so the tolerance per section matters more than it does on a one-piece blade.

Kit specification questions

How do I calculate the number of sections?

Divide the moldboard width by the section length, round up, and then check where the joints fall relative to the wheel tracks. Adjust the arrangement rather than accepting a joint in the wrong place.

It should cover it fully. A short kit leaves the outer strips uncleared, which on most roads is exactly where ice forms first.

Often yes, if the mounting pattern and trip mechanism allow it. Check the mounting geometry and the down-pressure the machine can apply before ordering.

The grade follows from the ice. Harder grades suit abrasive, steady surfaces; tougher grades survive the impact that comes with broken pavement and refrozen ruts.

Yes, at least one of each length. A missing section clears badly and loads its neighbours, so the spare is operational rather than optional.
