THE ACREAGE EQUIPMENT FIELD GUIDE
Match the attachment’s model, serial number and manual before ordering
A familiar model name is not enough to identify every component on a used or older-stock attachment. Match the actual machine to the document’s stated coverage before choosing a replacement part or accepting a seller’s specification sheet. A serial break inside one parts book can matter more than the date of a sales listing.

THE DECISION IN NUMBERS
Worked document match: similar names, different unresolved questions
Published boundaries and identifiers reviewed November 8, 2026. The machines offered in the examples are hypothetical. A match identifies a document branch for supplier review; it is not independent approval of a replacement part or modified machine.
Scroll the table sideways on smaller screens.
| Hypothetical machine or inquiry | Document evidence | Next decision |
|---|---|---|
| BX52S, serial 152S02144 | Parts manual p. 4; guard 1024L154 | Confirm that the installed assembly matches this branch |
| BX52S, serial 152S02145 | Parts manual p. 5; guard 1024L167 | Use the next serial branch; do not carry over the prior guard |
| FM-62 advertised as a 2024 machine | Manual library’s older links do not explicitly cover every year | Obtain the applicable document from its exact identity |
| FM-62/78 family belt inquiry | Page says BX39; 2023-current listing says XPB1240/BX46 | Resolve the configuration and approved identifier before ordering |

Start with the machine’s identity, not the listing title
Request a legible identification-plate photograph, the complete model designation and the serial number before agreeing to a parts package. Preserve letters and leading zeros. Ask separately for the manufacturing date, purchase date and known component changes. WoodMaxx’s FM manual requests the model/order or serial details together with manufacture and purchase dates for support. For older stock, a recent invoice does not establish recent manufacture, and a current product page does not prove that the machine has every current feature.
Separate document date from machine coverage
WoodMaxx groups its flail manuals under 2025-to-current and 2024-and-earlier headings; the older links are labeled 2019–2022 and before 2018. Those labels do not explicitly resolve a 2023 or 2024 machine. Ask which document applies rather than selecting whichever PDF is newest. Wallenstein’s BX52S support page separately lists operator, parts and setup documents, including an operator entry for machines before 2017. A parts-book diagram is useful for identification but is not a substitute for the applicable operating instructions.
Follow serial breaks inside the parts book
Wallenstein’s BX52S parts manual 1024T100, Revision C dated May 2024, provides two upper-housing diagrams. Printed page 4 covers serials 152S00002 through 152S02144 and lists PTO guard 1024L154. Page 5 covers 152S02145 through 152S04163, plus 1100000 and up, and lists guard 1024L167. The model stays BX52S across the boundary. These are identification examples for a supplier to confirm, not permission to interchange guards or a repair procedure.
Do not let a broad parts-family label settle a conflict
The FM-62 product page names BX39 drive belts, while WoodMaxx’s replacement listing identifies XPB1240/BX46, package XPB1240-3, for FM-62/62H and FM-78/78H from 2023 onward. A model-name match does not reconcile that difference. Ask the supplier to identify the correct belt set for the actual machine and explain any superseded number. The model-year label on one replacement package also does not establish which complete operator manual governs the mower.
Distinguish a matching record from a confirmed order
Consider a hypothetical BX52S identified as serial 152S02144 and another as 152S02145. They fall on different sides of the documented diagram boundary, even though their serials differ by one. That is enough to ask different identification questions. It is not enough to approve parts for a machine with a changed assembly or an unreadable plate. If the supplier cannot reconcile the identifier, installed component and document, leave the order unresolved instead of choosing the closest-looking item.
Keep the supplier’s answer with the purchase
Request the applicable manual title, document number, revision and serial scope in the reply, together with any replacement identifier that supersedes an older one. For a used-machine purchase, make an outstanding identification issue visible before comparing the cost of bringing it into service. Use this guide’s seller brief with the relevant product, add the identification details and describe any known changes. Keep the answer with your invoice so a future parts inquiry starts from the confirmed configuration rather than repeating the search.
Take these questions with you.
- Which complete model designation, serial number, manufacturing date and known component changes identify the exact machine being quoted?
- Which operator, parts and setup documents apply to that machine, including their document numbers, revisions and stated coverage?
- Does any serial break, model-year label or conflicting parts reference affect this order, and can you confirm the applicable identifier or supersession?
- What identification or configuration issue remains unresolved, and will your written quote record the confirmed machine and document scope?
Keep these questions with your exact tractor and attachment details.
