THE ACREAGE EQUIPMENT FIELD GUIDE
Choosing flail mower width for your tractor track
A mower’s model name is not a tire-coverage measurement. The useful comparison is actual cutting width against the outside rear-tire span of your tractor, plus the offset and overlap the job needs. Measure the machine you own before using a generic model recommendation.

Use cutting width, not shipping or body width
Farmry lists 45.3 inches for LFS45, 53.1 for LFS53 and 61 for LFS61. Those are the cutting-width values used here. The machine’s total exterior width and transport footprint are different dimensions. Confirm both if gateways, storage or fence clearance matter.
Calculate coverage without inventing a tractor dimension
For an illustrative measured tire span of 52 inches, a centered 53.1-inch cut extends only 1.1 inches beyond the total tire span, or about 0.55 inch per side. A 61-inch cut provides 9 inches total, or 4.5 per side. This arithmetic assumes a centered mower and says nothing about hitch geometry, side shift or suitability. Replace 52 with your own measurement.
The extra width has an operating cost
Published LFS weights including the shaft are 355, 395 and 421 lb as width increases. Moving from LFS53 to LFS61 adds 7.9 inches of nominal cutting width and 26 lb. That does not establish a measured productivity increase: vegetation, forward speed, terrain and PTO demand still affect work. The shared 15–35 hp range also needs its horsepower basis confirmed.
Use a conditional decision
Choose the narrowest option that provides the coverage your work needs while meeting the manufacturer’s requirements and the tractor manual’s limits. If an offset function is part of the plan, confirm its range, mechanism and hydraulic requirements on the exact product. Do not treat a diagram of an offset mower as evidence that every LFS configuration includes that setup.
Take these questions with you.
- What is the outside width of my fitted rear tires?
- How much overlap or offset does the job actually require?
- Does the exact mower revision satisfy power, load and hydraulic requirements?
