4″ max. chip diameter · 15–30 PTO hp
Confirm the conflicting tractor specifications in your serial-specific manual; official source values differ.
John Deere · COMPACT TRACTOR ATTACHMENTS
The 2038R’s official U.S. book lists 30 PTO hp, while its current-linked brochure lists 30.4. That small difference crosses the WC46’s upper limit. The same brochure gives 1,356 lb of lift at 24 inches for both 2032R and 2038R, so added PTO power does not establish added hitch capacity.

155ALV U.S. specification · 2-range HST · 4WD · ROPS
U.S. 2038R base code 155ALV, two-range hydrostatic, 4WD, open operator station/ROPS, from the 5 May 2026 specification book with U.S. destination 0202. Current-linked brochure is a qualified second source; exact serial applicability unresolved. Current page component contains conflicting drivetrain, hitch and hydraulic fields and is excluded for those values. Excludes 2032R and unverified earlier-generation or cab configurations.
Current 155ALV book gives 30.0 PTO hp; current-linked 04-25 brochure gives 30.4 with a manufacturer-estimate / 97/68/EC footnote.
Retain the book-scoped 30 value and alternative 30.4 explicitly. WC46’s 30 maximum remains conditional until exact serial/source applicability is established.
Component gives PowerTech PSS, PowrQuad transmission, Category 2/3N hitch and standard 21/optional 30 gpm. Model-specific book and brochure corroborate Yanmar diesel, hydrostatic transmission, Category 1 and 9.1/9.3 total gpm.
Exclude contradictory component fields from normalized specifications. Use the current page only for model identity and its linked documents; retain the component for the audit.
Book gives 36.8 HP / 37.3 PS (27.4 kW), SAE J1995; linked brochure labels 36.7 hp (27.4 kW).
Keep the book’s explicit HP/PS distinction and disclose the alternate label. Do not silently average or substitute engine power for PTO.
Book gives 5.2 implement / 3.9 steering / 9.1 total gpm; brochure gives 5.3 / 4.0 / 9.3.
Retain both published circuit splits and require serial-specific confirmation; neither is verified rear-coupler delivery.

FROM YOUR TRACTOR TO THE JOB
For the 2038R, a 0.4 hp source difference changes the smaller-chipper result: the U.S. book’s 30 PTO hp is at WC46’s maximum, while the current-linked brochure’s 30.4 exceeds it. Larger models with 20 or 25 hp minimums avoid that exact boundary but still need their load and capacity conditions checked.
Read the guide →FIELD GUIDEBoth published 2038R PTO figures meet FM-78 hammer’s 30 hp minimum, but only at the threshold or 0.4 hp above it. The linked brochure gives the same 1,356 lb at-24-inch hitch rating as 2032R, so a wider power-eligible mower still needs a separate carrying and cutting-load review.
