When choosing a flail mower attachment for your tractor, size isn’t just about mowing faster—it directly affects safety, cutting performance, and the type of terrain you can manage. Whether you're clearing trails, controlling tall grass, or maintaining ditches, choosing the right cutting width can save you time and money.

This guide explains how to select the ideal flail mower size for your land and tractor, using Farmry's heavy-duty lineup as reference.

Why Mower Size Matters

Flail mowers from Farmry range from compact 48″ models to 79″ wide professional attachments. The best choice depends on your tractor’s PTO horsepower, land type, and how much ground you want to cover in each pass.

A 3 point flail mower under 53 inches is ideal for tight spaces or narrow rows, while wider heavy duty mowers deliver top performance across open fields.

🔧 3 Point Hitch Mounting

All Farmry flail mowers are equipped with a standard 3 point hitch (Category 1 or 2) and quick-link pins for secure, fast setup. They're designed to stay stable on slopes and rugged ground.

🌿 Offset & Ditch Bank Mowing

Models with manual or hydraulic offset provide safer mowing near fences, trees, and waterways. These are ideal for ditch banks, slopes, or field edges that standard mowers can't safely reach.

↔️ Side Shift Function

Need extra flexibility in tight areas? Farmry’s side shift system allows you to move the mower laterally without adjusting tractor position—perfect for trimming around obstacles.

⚙️ Fast Blade Speed & Clean Finish

With high blade RPM, Farmry flail mowers shred tall grass and dense vegetation into fine mulch. Whether using Y blades or hammer blades, you get a safer, cleaner finish compared to rotary brush hogs.
