Farmry LFS45 vs LFS53: tire coverage, cutter width and weight
Choose the LFS45 or LFS53 around the width you need to cover, not the mower’s rounded model number. Their documented cuts are 45.3 and 53.1 inches, so the larger machine adds 7.8 inches of coverage and 40 pounds with the PTO shaft. That can help cover a wider rear tire track, but it also changes what must pass between trees and through access points. Both carry the same ambiguous horsepower band, so extra width does not bypass a tractor-specific power and stability check.

The differences that matter.
01
LFS53 adds 7.8 inches of working width
The product tables give LFS45 a 45.3-inch cut and LFS53 a 53.1-inch cut. Working width is the cutting swath, not the complete transport envelope.
Measure outside-to-outside tire track and actual access clearances. A mower that misses wheel tracks may need overlapping passes; a cutting-width number alone cannot establish gate clearance.
LFS Rev 1.7 lists 355 lb for LFS45 and 395 lb for LFS53 with PTO shaft. Shipping weights are 410 lb and 470 lb.
These are different weight bases. Discuss the assembled mower and its load center with the tractor manufacturer, while using shipping weights only to plan delivery/unloading.
LFS45 lists 16 hammers and LFS53 lists 18. Both are fixed mowers with 540 RPM PTO input and a stated 0.8-inch material limit.
The larger rotor adds two hammer positions to inspect and maintain. More hammers are not evidence of a better finish or a higher permitted material diameter.
Shortlist the LFS45 if 45.3 inches provides the coverage you need and the complete mower clears your routes. Its lower documented shaft-inclusive weight may help meet implement limits, subject to geometry and ballast confirmation. Do not choose it solely because the tractor’s engine rating falls within the printed HP band.
Consider LFS53 when the added swath solves a measured coverage problem
Shortlist the LFS53 if its 53.1-inch cut better covers your tire track or planned mowing area and the wider implement clears access points. The observed price increase is $100, but verify power suitability and the extra rear load before deciding that more width is automatically better value.
Farmry’s LFS45 category table lists 337 lb net, whereas Rev 1.7 lists 355 lb with PTO shaft. The comparison uses the latter labeled basis; the difference is not proof of a design change.
The shared 15–35 HP tractor range does not identify engine or PTO output. The separate 30 HP gearbox rating is a component rating, not the mower’s tractor minimum.
