Two 2018 Gator records, one pair format
The archive holds two John Deere Gator records for 2018: the XUV835E / XUV835M / XUV835R and the XUV865E / XUV865M / XUV865R. The XUV835 chapter prints 48 indexed rows; the XUV865 chapter prints 51. Both use the same format: an SPN, an FMI, and a printed title. Neither table prints a P-code, a C-code, or a U-code.
The two records cite separate owner’s manuals, OMUC13636 and OMUC13637, and separate chapters, SB31882,000027B and SB31882,000027E. The model year is 2018, inferred from the publication dates, the launch material, and the copyright page rather than from a model-year label in the table itself. The archive records that inference with the entries.
This is a label index. It does not provide repair procedures, parts advice, or a diagnosis for a specific machine. Codes can vary by trim, market, and running changes.
The pair is the printed key
The SPN and FMI columns carry the identifier in these tables. A row is complete when the SPN, the FMI, and the printed title are read together. SPN 84 at FMI 0 and SPN 84 at FMI 9 are different rows with different titles: Wheel Speed System Fault and Wheel Speed Not Detected. A citation that names only SPN 84 covers all six rows that carry that SPN across the two records.
Across the 99 rows, the archive counts 60 distinct SPN/FMI pairs, 36 distinct SPNs, 27 printed titles, and 13 FMI values. The counts differ because one SPN can print at several FMIs, and one title can cover several pairs. The pair count is the row-identity count; the SPN count and the title count each group rows.
| Record | Manual P/N | Chapter | Rows | Distinct pairs |
|---|---|---|---|---|
| Gator XUV835E / XUV835M / XUV835R | OMUC13636 | SB31882,000027B | 48 | 48 |
| Gator XUV865E / XUV865M / XUV865R | OMUC13637 | SB31882,000027E | 51 | 51 |
| Both records | 2 manuals | 2 chapters | 99 | 60 |
No pair repeats inside either record. The drop from 99 rows to 60 pairs comes entirely from pairs that both records print.
Shared and record-specific pairs
The two chapters overlap at 39 pairs. Those 39 pairs produce 78 rows, one in each record. The XUV835 chapter adds nine pairs of its own, and the XUV865 chapter adds twelve. The three counts account for all 60 pairs and all 99 rows.
| Group | Pairs | Rows | Example pair and printed title |
|---|---|---|---|
| Printed in both records | 39 | 78 | 84 / 0, Wheel Speed System Fault |
| XUV835 only | 9 | 9 | 51 / 31, CAN Communication Error |
| XUV865 only | 12 | 12 | 107 / 16, Engine Air Filter Restricted |
| Total | 60 | 99 | Both manuals |
The shared block includes the wheel-speed pair at SPN 84, the oil-pressure pair at SPN 100, the charging pairs at SPN 168, and the eight instrument-cluster pairs at SPN 520870 through 520876 plus 524265. The XUV835-only block includes the second CAN pair at SPN 51 and the four wheel-speed-limit pairs at SPN 1859. The XUV865-only block includes the glow-plug pairs at SPN 676, the fuel-solenoid and fuel-system pairs at SPN 516124 and 516125, and the second HVAC pair at SPN 523899.
FMI values in the two tables
The 13 FMI values are 0, 1, 2, 3, 4, 7, 9, 12, 13, 14, 15, 16, and 31. FMI 3 and FMI 4 each carry 21 rows. FMI 31 carries 20. FMI 0 and FMI 7 carry seven each. The remaining values carry between one and five rows. The archive reports the observed values and does not assign a universal meaning to any of them.
| FMI | Rows | FMI | Rows | FMI | Rows |
|---|---|---|---|---|---|
| 0 | 7 | 4 | 21 | 13 | 2 |
| 1 | 4 | 7 | 7 | 14 | 3 |
| 2 | 3 | 9 | 3 | 15 | 1 |
| 3 | 21 | 12 | 5 | 16 | 2 |
| 31 | 20 | ||||
Titles that repeat
The 27 printed titles are not spread evenly. Five titles cover 48 of the 99 rows. Instrument Cluster Control Unit Fault is the widest at 16 rows and eight pairs. CAN Communication Error covers 10 rows and seven pairs. Cooling System Circuit Fault and Communication System Fault CAN Communication Error cover eight rows and four pairs each. HVAC System Circuit Fault covers six rows and four pairs.
| Printed title | Rows | Pairs |
|---|---|---|
| Instrument Cluster Control Unit Fault | 16 | 8 |
| CAN Communication Error | 10 | 7 |
| Cooling System Circuit Fault | 8 | 4 |
| Communication System Fault CAN Communication Error | 8 | 4 |
| HVAC System Circuit Fault | 6 | 4 |
| Five titles above | 48 | 27 |
The other 22 titles cover 51 rows. A pair such as 167 / 3 and 167 / 4 both print Charging System Circuit Fault, so the title count stays below the pair count. The archive keeps the printed string, including capitalization and the missing hyphen in Elec Accessory Supply Circuit Fault.
The blank row and the printed count
Each chapter prints one more data row than the archive holds. The XUV835 chapter prints 49 rows and the XUV865 chapter prints 52. In each chapter, one row carries SPN 523910 and FMI 31 with no printed title. The archive omits that empty row, which leaves 48 and 51 indexed rows.
The omission is recorded rather than hidden. A reader comparing the page with the manual will see the row count difference, and the citation note names the blank pair. The archive does not assign a title to a cell the manual leaves empty.
What the two tables do not show
The chapters print no display-code column, so a reader cannot resolve a P-code against these rows. They also do not split the E, M, and R trims into separate tables. Each record covers three trim names with one chapter and one row set. The archive records the group as printed and does not claim that every trim carries every feature named in a title.
The archive holds no 2019 or later Gator chapter. The two 2018 records are the full John Deere coverage, and the year is an inference from the manual front matter. A different model year would need its own manual P/N and chapter.
How to cite a John Deere Gator row
Name the manual P/N, the chapter, the SPN and FMI pair, and the printed title. For example: OMUC13636, chapter SB31882,000027B, SPN 100 at FMI 1, Engine Oil Pressure Low. The P/N separates the two 2018 records; the pair separates rows within a chapter.
If the pair is shared, the citation still names the manual. The printed title is identical across the shared block, but the page and the manual remain the source for the row. A pair-only citation without a P/N covers both records and is therefore less precise.
Questions about the Gator tables
How many John Deere Gator records does the archive hold?
Two, both for 2018: the XUV835E / M / R and the XUV865E / M / R. They cite OMUC13636 and OMUC13637.
Do the two records print the same table?
No. They share 39 SPN/FMI pairs, but the XUV835 chapter adds nine pairs and the XUV865 chapter adds twelve. The row counts are 48 and 51.
Why is the archive row count one lower than the manual?
Each chapter prints one blank row at SPN 523910, FMI 31. The archive omits the row because it has no printed title. The printed counts are 49 and 52.
Does a John Deere row carry a P-code?
No. The two 2018 Gator chapters print SPN, FMI, and a title. The archive does not assign a display code to a row that does not print one.
Which FMI values appear?
13 values: 0, 1, 2, 3, 4, 7, 9, 12, 13, 14, 15, 16, and 31. The archive reports the values and their row counts without assigning a universal meaning.
