Size a weld-on edge for a skid steer by matching the edge to the machine’s rated operating capacity, the bucket or blade width it will be welded to, and the pin-on or weld-on interface geometry — then confirm base edge thickness, edge width, and bevel against the attachment drawing rather than the machine brochure. A weld-on edge is a structural part of the attachment, so the dimensions that matter are the ones on the bucket or blade, not the loader’s spec sheet.
Start from the attachment, not the loader
The most common sizing error in this category is buying to the skid steer model instead of to the attachment that carries the edge. Loaders of the same rated capacity routinely run buckets from different fabricators, and base edge thickness, lip angle, and weld prep vary between them. Measure the attachment first, then use the loader only to confirm the duty class.
Key dimensions to record before ordering
A weld-on edge is defined by a small set of dimensions, and every one of them needs to come off the attachment or its drawing. Record them in this order before you contact a supplier.
- Base edge thickness — the thickness of the bucket or blade lip the edge welds to. The weld-on edge should be matched to it, not chosen independently.
- Edge width (face height) — how much wear material stands proud of the base edge. This drives wear life and breakout behaviour.
- Overall length and segment count — whether the edge is one piece or split into sections across the bucket width.
- Bevel geometry — the cutting angle and whether the bevel is on the top or bottom face.
- Weld prep and fit-up clearance — whether the edge is supplied with a prepared root or requires field preparation.
- Attachment interface — for a weld-on edge this is the weld line itself, but confirm there is no pin-on or bolt-on pattern on the same attachment that the edge must clear.
Dimensions and hole spacing follow the product page specification. Where an attachment has been repaired or re-lipped in the field, verify against the physical part rather than the original drawing.
Thickness, width, and duty class
Thickness and face width should be selected against the duty class of the machine and the abrasive conditions of the site, not against a single nominal figure. The table below gives the relationship between the variables rather than fixed values, because the correct combination depends on the attachment and the application.
| Variable | What it affects | How to decide |
|---|---|---|
| Edge thickness | Stiffness, weldability to the base edge, wear reserve | Match to base edge thickness; going heavier than the lip can support shifts stress into the weld |
| Face width | Wear life, penetration, breakout force | Wider for abrasive ground and high-hour fleets; narrower where penetration matters more than life |
| Bevel angle | Cutting efficiency vs. edge strength | Depends on material being moved — abrasive aggregate versus compacted snow and ice |
| Segment count | Replacement cost, field service time | Split edges cost less per replacement and are easier to handle in the field |
| Steel grade | Wear rate vs. weldability and toughness | Higher wear resistance generally trades against field weldability |
There is no universal “correct” thickness for a given loader size. Two contractors running the same machine in different ground conditions will land on different specifications, and both can be correct.
Weld-on versus bolt-on: what changes in sizing
A weld-on edge removes the bolt pattern from the equation but adds the weld line as a structural constraint, which changes how much freedom you have on thickness and fit. Bolt-on edges can be shimmed or re-drilled; a weld-on edge cannot, so the fit-up check matters more.
The trade-off is straightforward: weld-on edges generally give a more rigid cutting assembly and lower per-edge cost at volume, but replacement requires cutting and re-welding, which carries labour and downtime that bolt-on does not. For fleet procurement, that downtime is a real line item and should be modelled alongside the edge price. If you are seeing uneven consumption across a fleet, the checks in one end of the edge wearing faster are worth running before you re-specify.
The commercial side: MOQ, lead time, and specification risk
Weld-on edges are usually cut and formed to order, so commercial terms track the specification rather than a catalogue part number. Buyers should expect minimum order quantities to depend on profile and steel grade, with common profiles available at lower MOQs than non-standard widths or bevels.
Lead time depends on whether the profile is a stock pattern or a made-to-order cut, and on steel availability at the time of order. For fleet procurement, the practical risk is specification drift: if the attachment drawing is not pinned to the purchase order, successive orders can arrive with small differences in face width or bevel that only show up at fit-up. The mitigation is to attach the measured dimensions to the PO and to keep a reference edge on the shelf as a physical standard. Total cost of ownership should be calculated per operating hour, not per edge, because a lower-cost edge with a shorter wear life can cost more across a season. Full dimensional and grade options are listed on the weld-on edge for skid steer product page, and buyers comparing profiles across attachment types can review the wider cutting edge range before finalising a specification.
Fit-up and weld preparation checks
Most field failures in weld-on edges trace back to fit-up rather than to the edge itself. Before welding, confirm the base edge is straight and free of previous weld build-up, and check that the new edge seats without a gap along its length.
Confirm the bevel orientation matches the intended cutting direction, and verify that the weld procedure is appropriate to the steel grade supplied — some wear-resistant grades require preheat or specific consumables. These are fabrication decisions, but they belong in the sizing conversation because they constrain which grades are practical for a given fleet’s workshop capability.
Quick summary
Size a weld-on skid steer edge from the attachment drawing — base edge thickness, face width, length, and bevel — and use the loader only to confirm duty class. Thickness and width are application-dependent, so specify per operating hour rather than per edge price, and pin the measured dimensions to the purchase order to prevent specification drift across repeat orders.

Three more perspectives
Workshop: The fabricator cares about fit-up gap, base edge straightness, and whether the steel grade needs preheat. A dimensionally correct edge that will not seat is a rework job, so the workshop wants the measured attachment, not the loader model.
Purchasing: MOQ and lead time follow the profile and grade, not a part number. The main risk is specification drift between orders, which is controlled by attaching dimensions to the PO and holding a reference edge.
Field: Operators judge the edge by penetration and wear life, and those two pull in opposite directions on face width and bevel. Field feedback should feed back into the next specification rather than being treated as a quality complaint.
Limits
This page does not provide a size chart, torque values, weld procedure specification, or steel grade recommendations for specific machines, and it does not substitute for the attachment manufacturer’s drawing. Wear life and cost figures are application-dependent and are given as ranges and relationships only. Buyers should confirm all dimensions against the physical attachment or its drawing before ordering.
