Scope of this guideL3970PRM · HST Plus · 3 ranges · 4WD · ROPS/Cab. Each configuration below states the model and equipment covered by its sources.

Screen PTO-rated attachments against 30.9 hp and expect results within a horsepower of 30 to need the maker’s confirmation. For mowers rated without a basis, the 30.9 PTO and 39 engine figures often give different answers.

  • Kubota lists 39 gross hp (SAE J1995) and 30.9 PTO hp at 2,300 engine rpm for the L3970 Premium; 540 PTO rpm comes at 2,299.
  • 30.9 PTO hp clears the 30-hp minimum of WoodMaxx FM-78, FM-78H and FM-78 Y by 0.9.
  • The same figure is 0.9 over the 30-hp maximum of Woodland Mills WC46 and TFG55; WC68 (20–50) is the Woodland chipper inside.
  • Farmry LFS (15–35 hp) is inside on PTO power and 4 over on engine power; Land Pride FM2560 (33) is the reverse.
  • The L4270 Deluxe lists more PTO power (32.5) and lift at 24 inches (2,756 lb) despite the lower trim.

FIELD GUIDE

Kubota L3970 Premium flail mowers: FM-78 by 0.9 hp, LFS and FM2560 on the basis

The L3970 Premium’s 30.9 PTO hp clears the 30-hp minimum of WoodMaxx’s 70-inch FM-78 family by 0.9. Its two power figures split the mowers rated without a basis: Farmry’s LFS range (15–35 hp) includes 30.9 PTO hp but not 39 engine hp, and Land Pride FM2560 (33 hp) is the reverse. The L3770 Deluxe, on the same frame at 28 PTO hp, misses FM-78 by 2.
