THE TRADEOFFS, EXPLAINED

Farmry LFS45 vs LFP47: hammer blades or Y-blades in a compact cut?

LFP47 adds just 1.9 inches of manual-listed cutting width over LFS45, but changes the blade arrangement and adds about 109 lb of listed weight with the shaft. This is more than a choice between a 45-inch and a 47-inch label. Ask whether the supplied Y-blades suit your vegetation, then resolve the higher, unlabeled tractor-power range before considering the heavier mower.

START WITH THE DECISION

LFS45: the lighter, narrower hammer optionConsider when the narrower hammer-equipped mower suits the task and the lower published weight is useful, after Farmry resolves horsepower basis and the tractor passes other checks.

LFP47: a fixed deck with Y-bladesConsider when a Y-blade setup suits regular grass/weed maintenance and the additional weight and higher power range are acceptable; confirm power basis and delivered parts.

The differences that matter.

01

Blade configuration

LFS45: 16 hammer blades. LFP47: 32 Y-blades.

Choose the documented cutting setup for the vegetation task; blade counts across different designs are not a cut-quality ranking.

02

Working width

LFS45: 45.3 inches. LFP47: 47.2 inches; marketed as 47.

LFP47 adds 1.9 inches of manual-listed cut. Compare each with actual rear tire track and access width.

03

Weight with shaft

LFS45: 355 lb in current LFS Rev 1.7 manual. LFP47: 464 lb on LFP47 page; manual 463.7 lb.

LFP47 adds about 109 lb to these published shaft-inclusive figures; that deserves a load/ballast check despite the small width change.

04

Published tractor range

LFS45: 15–35 HP, basis unspecified. LFP47: 25–45 HP, basis unspecified.

LFP47 raises the listed lower bound by 10 HP. Neither range can be matched to engine or PTO output until Farmry identifies the basis.

Keep these source limits with the decision.

Both tractor-power ranges omit engine/PTO basis. The LFP47 gearbox rating is not its tractor minimum.

LFP47’s page says SAE90 EP while Rev 1.3 manual specifies SAE 85W-90 API GL-5. Resolve the supplied revision with Farmry.
