Keep these source limits with the decision.

LFP47: Farmry labels 25–45 HP as tractor power without saying engine or PTO; the 30 HP gearbox rating is a component rating, not the tractor minimum.

FM-78 Y: the page lists 710 lb mower-only plus a 39-lb shaft; the manual gives 880 lb.

This comparison reuses the manufacturer evidence retained in the product records reviewed November 7, 2026; product pages were not re-fetched on November 9. Document conflicts are kept visible. No field test or manufacturer-approved tractor pairing is claimed.
