Scenario: you need an edge for an older municipal plow, and the crew calls it by a brand style without knowing the model. Direct answer: do not order from a brand name or a family label. Identify the plow by its model plate and by measurement, and send the supplier those facts. I describe no brand or compare any makers here, since I have no verified data on specific plow families; the sheet below is a method.
Identification sheet
| Item | How to get it | Write here |
|---|---|---|
| Plow maker and model | Plate on the moldboard frame or the back of the plow | |
| Serial number and year | Same plate; or the manual | |
| Moldboard height and length | Tape measure, with the plow on level ground | |
| Edge type | Single piece, segments or inserts; steel, carbide or rubber | |
| Edge length | Measure the old edge end to end | |
| Edge width and thickness | Calipers, at three points | |
| Bolt hole count, size and spacing | Measure the centre to centre and the hole diameter | |
| Hole shape | Round, slotted or countersunk; note which side | |
| Bolt size and type | Measure the old bolt and look at the head | |
| Photographs | Front, back, and a close-up of the holes with a ruler |
Steps
Identifying the plow family is the step that prevents a wrong order.
- Clean the plate and the edge, then fill in the sheet.
- If the plate is missing, search the maker’s manuals or ask the maker or dealer.
- Send the sheet and pictures to two suppliers and ask each to confirm the fit in writing.
- Order one set first when the plow is old or unusual, and check the fit before ordering more.
- Store the completed sheet with your fleet records.
Common traps
Most wrong orders start with an assumption about the plow family.
- Assuming two plows from the same maker take the same edge.
- Ordering by the length alone without checking the bolt pattern.
- Forgetting that a previous owner may have modified the plow.
Limits
Measurements and photographs reduce, but do not remove, the risk of a misfit. Confirm with the supplier before ordering large quantities.
If the plate is missing
Old plows often lose their plates. Look for a casting number, a maker’s name on the frame or the moldboard, or a number stamped near the hitch. Photograph whatever you find. A dealer or the maker’s parts desk can often identify a plow from clear photographs and the measurements in the table. If nobody can, treat the plow as unidentified and order one set only until the fit is proved, then record the working part number on your sheet.
Boundary: No plow brand or family is described or compared; confirm fit with the supplier before ordering large quantities.
