5 best sickle mower attachments for Overgrown Fields

That back field, the one you’ve been meaning to get to, has exploded into a jungle of thigh-high grass and stubborn thistles. A standard mower would choke in minutes, and a brush hog would just shred everything into an unusable mess. This is where the elegant, old-school efficiency of a sickle mower shines, offering a clean, precise cut that tames the wild without destroying the forage.

Why a Sickle Mower for Your Overgrown Pasture?

Unlike a rotary mower that uses a spinning blade to violently chop and mulch, a sickle bar mower operates with a gentle, scissoring action. It uses a series of triangular blades (called knives or sections) that reciprocate back and forth against stationary guard fingers. This action cuts stalks cleanly at their base, much like a pair of scissors, causing minimal damage to the plant and requiring significantly less horsepower than a flail or rotary cutter.

This clean cut is the key to its value on a small farm. It lays the grass down in a neat swath, perfectly prepped for raking and baling if you intend to make hay. Even if you’re just topping a pasture to control weeds, this method leaves the clippings long, allowing them to break down into the soil more effectively than a pile of shredded mulch. Furthermore, their ability to operate at steep angles makes them invaluable for cutting ditch banks, pond edges, or under fence lines where a tractor-pulled brush hog simply can’t go.

Choosing Your Sickle Mower: Key Considerations

Before you invest, you need to match the mower to your land and your power source. The first and most important decision is whether you need a walk-behind model or a tractor-mounted attachment. A walk-behind offers incredible maneuverability for steep slopes, tight orchards, and complex terrain, while a tractor-mounted unit provides speed and efficiency for covering several open acres.

Once you’ve decided on the type, consider these critical factors:

• Cutting Width: Wider isn’t always better. A 4-foot bar on a walk-behind is nimble and easy to handle in tight spots, while a 7-foot bar on a tractor will make quick work of a hayfield but can be cumbersome around obstacles.
• Drive Mechanism: Most modern sickle bars use a "wobble box" or double-action drive system, which is smoother and more reliable than the old pitman arm drives. For tractor attachments, ensure your PTO speed (usually 540 RPM) and horsepower are a good match for the mower’s requirements.
• Terrain and Obstacles: If your fields are littered with rocks, look for models with "rock guards" that are more durable. Some mowers also feature a breakaway mechanism that allows the bar to swing back if it hits an immovable object, saving you from costly repairs.

BCS Sickle Bar Mower: The Walk-Behind Workhorse

If you have varied terrain with slopes, ditches, and tight corners, the BCS sickle bar mower is your gold standard. These Italian-made walk-behind tractors are legendary for their versatility and climbing ability. The engine is the power unit, and the sickle bar is just one of many attachments you can run, including a tiller, chipper/shredder, and snow thrower, making it a true year-round system for a small farm.

The BCS design puts the heavy engine directly over the wheels, giving it incredible traction and balance on hillsides where a riding mower or tractor would be dangerously unstable. The sickle bars themselves are engineered for performance, with options for different types of guards to suit your conditions. They excel at cutting under fence lines, around fruit trees, and along pond banks.

This is the right machine for the farmer who needs more than just a mower. If your property demands a versatile tool that can handle multiple jobs on challenging terrain, the investment in a BCS system pays for itself in safety and capability. However, if you simply have five flat, square acres to cut, it’s not the fastest option.

Kuhn GMD Series: For Compact Tractor Efficiency

Let’s be clear: the Kuhn GMD is a disc mower, not a traditional sickle bar. However, for the compact tractor owner looking to make hay from an overgrown field, it serves the same purpose with a massive leap in technology and speed. Instead of a reciprocating knife bar, a GMD uses multiple small, high-speed rotating discs, each with two blades. This design allows you to mow at much higher ground speeds without the risk of clogging that can plague sickle bars in heavy, wet growth.

This mower is for the hobby farmer who is serious about making their own hay and has relatively clean, open fields. It requires a tractor with sufficient horsepower (typically 25hp and up) and a rear PTO. The cut quality is excellent for haymaking, and its speed can turn a full day’s work with a sickle bar into a two-hour job. The main tradeoff is its intolerance for hidden obstacles; a rock or stump that might just break a sickle knife section can cause significant damage to a high-speed disc mower gearbox.

If your primary goal is efficient hay production on several acres, the Kuhn GMD is your tool. It represents the modern evolution of hay cutting. But if you’re clearing rough, unknown ground or cutting steep ditch banks, the higher cost and vulnerability to damage make a traditional sickle bar or a rugged brush hog a safer bet.

Grillo Sickle Bar: Versatility and Precision

Much like BCS, Grillo produces high-quality, Italian-made walk-behind tractors with a range of sickle bar attachments. They are direct competitors, and choosing between them often comes down to specific features and user feel. Grillo machines are renowned for their excellent balance, active clutches, and intuitive controls, which many users find make them slightly more nimble and less fatiguing to operate over long periods.

Grillo offers a variety of cutter bars, including oil-bath "greaseless" versions that reduce daily maintenance—a significant plus for a time-strapped part-time farmer. Their focus on precision makes them ideal for tasks like cutting between rows of lavender, managing wildflower meadows, or carefully trimming around delicate plantings. They provide the same all-terrain, all-season versatility as other walk-behind systems.

Choose the Grillo if you prioritize refined handling and precision work. If you’ve priced out a BCS and want to evaluate its closest competitor, a Grillo is a must-see. It’s a premium machine for the discerning landowner who needs a reliable, multi-purpose tool for intricate property maintenance.

DR Power Sickle Mower: Taming Tall Grasses

The DR Power Sickle Mower is a purpose-built machine for the American landowner. Unlike the European walk-behind systems, this is a dedicated mower designed to do one job exceptionally well: cut down overgrown fields, thick weeds, and even small saplings. It’s a self-propelled walk-behind that is simpler in design and typically more affordable than a BCS or Grillo.

This mower is built for brute-force clearing. It’s not designed for the finesse of making perfect hay, but for reclaiming a pasture, clearing a trail, or knocking down a season’s worth of growth in a hurry. The wide, knobby tires provide excellent traction, and the straightforward controls make it easy to get started right away. It’s a workhorse for the person who doesn’t need a swappable attachment system.

This is your mower if you need a powerful, dedicated tool for annual or semi-annual field clearing. It’s perfect for the homesteader with 1-5 acres of unruly pasture who doesn’t have a tractor and doesn’t need the expense or complexity of an attachment-based system. It is a master of one trade, and it does it very well.

Enorossi BFS Mower: Durable and Field-Ready

For the hobby farmer with a compact utility tractor, the Enorossi BFS series (and similar models from other Italian makers like Sitrex) represents the classic, reliable, and affordable sickle bar mower. These are 3-point hitch, PTO-driven implements that embody a time-tested design. They are mechanically simple, making them easy to maintain and repair with basic tools—a huge advantage on a small farm where downtime is costly.

These mowers are workhorses. They don’t have the speed of a disc mower, but they require less horsepower and are far more forgiving when you inevitably find a hidden rock or fence post. The Enorossi BFS can be hydraulically lifted for transport and can cut at a wide range of angles, making it perfect for doing ditch and bank work that is unsafe or impossible with other mowers.

If you own a compact tractor (18-40hp) and need a cost-effective way to make hay or manage pastures, this is your answer. It’s a no-frills, durable tool that gets the job done without the high price tag or complexity of more modern designs. It is the definition of a practical farm implement.

Maintaining Your Sickle Bar for a Longer Life

A sickle mower will serve you for decades, but only if you give it the attention it needs. Its many moving parts require consistent, simple maintenance to prevent catastrophic failure. Neglect is its worst enemy.

First, grease is your best friend. The drive head, whether it’s a wobble box or a pitman arm, moves at high speed and needs frequent lubrication. Check your manual, but a pump of grease every 8-10 hours of use is a standard rule of thumb. Second, keep the knives sharp and tight. Dull or loose knife sections will tear and clog rather than cut cleanly. Check for broken sections before each use and replace them immediately. Modern bolt-on sections make this a much easier job than the old riveted style.

Finally, pay attention to the guards and ledger plates. These stationary parts provide the "anvil" for the cutting action. If they become bent, broken, or out of alignment, your cutting performance will suffer dramatically. A quick visual inspection and cleaning off mud and debris after each use will save you hours of frustration in the field.

Safe Operation: Tips for Using Your Sickle Mower

The quiet operation of a sickle mower can be deceptive—it is an incredibly dangerous piece of equipment that demands your full respect. The blades can cause severe injury even when the machine is off. The single most important safety practice is to walk your field before you mow. Look for rocks, wire, old fence posts, stumps, and animal burrows that could damage the machine or cause an accident.

When operating, always keep hands and feet far away from the cutter bar. If the bar clogs with grass, shut down the engine completely before attempting to clear it by hand. Never try to kick or pull a clog free while the machine is running, as the stored energy can cause the bar to suddenly cycle.

On slopes, safety is paramount. With a walk-behind unit, always work across the face of the hill, never straight up or down, to maintain stability. For tractor-mounted mowers, be intimately familiar with your tractor’s limits to prevent a rollover. Always keep your PTO shields in place; an exposed, spinning PTO shaft is one of the most dangerous things on a farm.

Final Verdict: Matching the Mower to Your Field

Choosing the right sickle mower isn’t about finding the "best" one, but the one that’s best for your specific situation. The decision boils down to a simple framework: your power source, your terrain, and your primary goal.

If you are working without a tractor, or if your land is steep, wooded, or full of obstacles, a walk-behind is your clear choice. The BCS and Grillo offer ultimate versatility for the serious farmer who needs one power unit for many jobs, while the DR Power mower provides a powerful, dedicated solution for pure clearing. If you have a compact tractor and several acres of open ground, a tractor-mounted attachment is the only logical path for efficiency. The Enorossi offers a simple, durable, and affordable sickle bar perfect for general use, while the Kuhn GMD disc mower provides a massive leap in speed for those serious about making hay.

Ultimately, the goal is to reclaim and manage your land effectively. By honestly assessing your property and your needs, you can select a tool that will not only tackle that overgrown field but will become an invaluable part of your farm’s success for years to come.

Reclaiming an overgrown field is one of the most satisfying jobs on a farm, turning a chaotic mess into productive pasture or valuable hay. A sickle mower is a specialist’s tool, and by choosing the right one, you empower yourself to manage your land with precision and purpose.
