Notes
Six arguments that did not fit on a reference page.
The reference sections of this site describe documents, and a page about hitch categories will say substantially the same thing next year because ASABE S217 will. A note is different: it takes an observation that cuts across several reference pages and works it through as an argument. Why a regulatory band edge shows up as a marketing horsepower figure, why three loaders quoting the same capacity are not equivalent machines, why the weight thresholds in federal rule do not line up with one another.
Those are views at a moment rather than descriptions of documents, so they carry publication dates. There is no posting schedule, because a publication that writes to a calendar rather than to a reason ends up padding.
What a note is, and how it differs from a reference page
The reference sections of this site describe documents. A page about three-point hitch categories is describing ASABE S217, and it will say substantially the same thing next year because the standard will. That is the point of it, and it is why those pages carry a review date rather than a publication date.
A note is different. It takes an observation that cuts across several of those pages and works it through as an argument. Why a regulatory band edge shows up as a marketing number, why three machines quoting the same capacity are not equivalent, why the thresholds in federal rule do not line up with one another.
Those are views at a moment rather than descriptions of documents, so they carry a publication date and they are signed by the publication rather than presented as neutral reference.
There is no schedule and there will not be one. A note appears when there is something worth saying that does not fit on a reference page, and a publication that posts to a calendar rather than to a reason ends up padding.

Notes are written by Tractor & Heavy Equipment Guide rather than by a named author, which identifies the publication responsible for the text. Attributing an editorial view to an invented byline would be a fabrication, and attributing it to a real person would imply an individual expert view where what the publication offers in these notes is a publication's reading of documents it cites. Where a note draws a conclusion the sources leave unsaid, it says so.
Straight answers
Notes: Questions and answers
How often are new notes published?
There is no schedule and there will not be one. A note appears when there is something worth saying that does not fit on a reference page. A publication that posts on a calendar rather than because it has something to say ends up producing filler, and filler on a reference site is worse than silence.
It dilutes the material that answers an equipment decision and it trains readers to skim.
Why do notes have no named author?
Because inventing a byline would be a fabrication and attributing an editorial view to a real named person would imply an individual expert opinion where what is offered is a publication's reading of documents it cites. Notes are written by Tractor & Heavy Equipment Guide, they name their sources, and where a note draws a conclusion the sources leave unsaid, it says so explicitly rather than implying the source said it.
What is the difference between a note and a reference page?
A reference page describes a document, a standard, a regulation, a test procedure, and it will say substantially the same thing until that document changes. A note is an argument that connects several of them, and it is a view at a moment rather than a description. Reference pages carry review dates; notes carry publication dates, and the difference is not cosmetic.
How many notes has this site published so far?
Six, published between mid-August and early September 2026, each addressing a single cross-cutting observation: a regulatory band edge showing up as a horsepower cluster, three loaders quoting one capacity figure by three methods, weight thresholds that do not line up, what the used market gets right, the low-hour machine problem, and how to read a load chart.
Do notes ever get updated after publication?
A note's publication date identifies the sources and reasoning available for that argument. A materially changed source or an identified error calls for a correction: see the corrections page for how a report is handled, and the publication date identifies when the recorded argument was made.
Can I cite a note the same way I would cite a reference page?
Yes, though the citation should reflect what it is, a dated editorial argument rather than a description of a standing document, since a reference page's content is expected to remain accurate as long as the underlying standard does, while a note's conclusions are tied to the reasoning and sources available as of its publication date.
Are notes fact-checked to the same standard as reference pages?
Yes: every factual claim in a note is sourced exactly as rigorously as a reference page's claims, following the same how we source and verify standard; what differs is the genre, not the requirement to identify the source. A note's argument is original synthesis, but the facts it synthesizes are held to the same bar.
Why does this site call these "notes" rather than "articles" or "blog posts"?
"Notes" identifies the intended reading format: a focused, dated observation connecting existing reference material, rather than the broader, more varied scope "blog post" usually implies or the more neutral, undated tone "article" suggests on the rest of this site.
Do notes count toward the same word-count or depth standard as the reference pages?
A note develops one equipment observation using the cited documents and linked reference material. It can connect a load-chart restriction, a rating method or a regulatory threshold with the decision that depends on it. The corresponding reference guide covers the broader equipment topic.
Can a note reference a reference page that was published after the note itself?
No: a note links only to reference material that existed at the time it was written, since it is a snapshot of the site's reasoning at that date; if relevant reference material is added later, the note may be updated to link it, but the note's own dated argument does not retroactively assume content that did not yet exist.
Are notes ranked or ordered by importance, or strictly by publication date?
Strictly by publication date, both on this hub page and in the site's internal linking: there is no editorial ranking by importance, since a note's value depends on what a specific reader is trying to understand, not on an editorial judgment about which argument matters most in general.
What happens to a note if the regulation or standard it discusses is later revised?
The note is reviewed and, where the revision changes the argument's factual basis, corrected or annotated to reflect the change: the publication date marks when the original argument was made, and a substantive correction is recorded rather than silently edited, consistent with the site's corrections policy.
