6 Best Compact Windrowers for Small Farms

You’ve watched your pasture grow all spring, a thick, green carpet waving in the wind. Now it’s time to turn that grass into winter feed for your animals, but the thought of cutting five acres with a scythe is daunting. This is the moment many homesteaders realize they need to mechanize their haymaking. The right compact windrower can transform this monumental task into a manageable, even enjoyable, process without requiring a massive tractor or a second mortgage.

What to Look for in a Small-Scale Windrower

The best machine is the one that fits your land, your power source, and your crop. Hilly, rough terrain demands a different solution than a flat, manicured field. A walk-behind tractor excels on steep slopes where a pull-type mower would be unstable, while a compact tractor with a 3-point hitch mower makes quick work of open ground.

Think about what you’re cutting. Fine grass hay is less demanding than thick, stemmy alfalfa or a tangled mix of field grasses. Sickle bar mowers are gentle on delicate, leafy forages like alfalfa, preserving precious protein. Drum mowers, on the other hand, are less prone to clogging and will power through almost anything, but can be rougher on the crop.

Finally, consider your budget and mechanical aptitude. A well-maintained used machine can be an incredible value, but only if you can still find parts for it. A cheap mower with no parts support is just an anchor. Don’t forget to factor in the power requirements; a mower that’s too heavy or power-hungry for your tractor is useless.

BCS 620 with Duplex Windrower: Versatile Power

The BCS isn’t just a mower; it’s a power platform. For a small homestead, this versatility is its greatest strength. The walk-behind tractor can run a tiller, a snowblower, a chipper, and, most importantly for hay, a high-quality sickle bar mower.

The Duplex sickle bar attachment is the star of the show. It uses two blades moving in opposite directions, which dramatically reduces the vibration common to single-blade sickle bars. This creates a smoother, faster, and cleaner cut that is exceptionally gentle on hay, laying it down in a perfect, fluffy windrow for drying. It’s a precision instrument.

This level of performance and versatility comes at a price. A new BCS setup is a significant investment, but used units hold their value well and are a smart buy. If you can leverage its multi-tool capability across all four seasons, the cost-per-use plummets, making it one of the most budget-wise systems for a diversified homestead in the long run.

Grillo G107d with Sickle Bar for Tough Terrain

Think of the Grillo as the rugged cousin to the BCS. These Italian-made walk-behind tractors are built for work, with a reputation for durability and excellent handling on challenging ground. Many models come with a locking differential, which is a game-changer for maintaining traction and control on steep hillsides.

Paired with a standard or double-action sickle bar, the Grillo is a formidable haying machine. It excels at navigating tight spaces, mowing around obstacles, and safely cutting on slopes that would make you nervous on a compact tractor. The sickle bar lays the hay down gently, preserving leaf and quality, which is crucial for nutrient-dense winter forage.

The choice between a Grillo and a BCS often comes down to local dealer support and personal preference. The Grillo’s straightforward, robust design appeals to many who prioritize pure function and stability over the broader range of attachments offered by competitors. If your five acres are more vertical than horizontal, the Grillo deserves a serious look.

New Holland 451: A Reliable, Budget Pull-Type

If you have a compact tractor with a PTO, the world of used pull-type mowers opens up. The New Holland 451 is a legend in this category. It’s a simple, pitman-drive sickle bar mower that was produced for decades, meaning there are thousands of them sitting in barns and fence rows across the country.

Their biggest advantage is availability and affordability. You can often find a working 451 for just a few hundred dollars. Better yet, parts are still readily available from New Holland dealers and aftermarket suppliers. This is a machine you can actually keep running on a shoestring budget.

The tradeoff for that low price is speed and maintenance. A pitman drive requires regular greasing and is more prone to vibration and wear than newer designs. It can also clog more easily in heavy, wet hay. But for a few acres of clean grass hay each year, the NH 451 is arguably the best entry point into mechanized mowing.

John Deere 350 Mower: A Durable Used Market Gem

The John Deere 350 is a 3-point hitch sickle bar mower and represents a significant step up from older pitman-drive models. It uses a quieter, smoother belt-drive mechanism (often called a "wobble box") to power the cutter bar. This design reduces maintenance and vibration, making for a more pleasant and reliable mowing experience.

These mowers were built to last, with a heavy-duty frame and quality components. They attach quickly to a standard 3-point hitch, making them much more maneuverable than a pull-type mower for getting into corners and working around obstacles. They are an excellent match for the 20-30 horsepower compact tractors common on homesteads.

While you’ll pay more for a used JD 350 than an old NH 451, the investment often pays for itself in reduced downtime and better performance. It hits a sweet spot, offering modern reliability without the high cost and horsepower requirements of a disc or drum mower. It’s the perfect upgrade for the homesteader who has decided to get serious about their hay program.

Galfre 165 Drum Mower: Simple and Effective

When you just need to get the grass cut, quickly and without fuss, a drum mower is your answer. Instead of a complex sickle bar, a drum mower uses two large, counter-rotating drums with free-swinging blades that use centrifugal force to cut. This design is incredibly simple, robust, and almost impossible to clog.

The Galfre 165 is a popular and well-regarded example of this type of mower. It will power through thick, tangled, or wet grass that would stop a sickle bar in its tracks. Maintenance is minimal—check the gearbox oil and replace the inexpensive blades when they get dull or damaged. It’s a brute-force approach to mowing that is highly effective.

The main drawback is that a drum mower is rougher on the crop. The spinning drums create a lot of air movement and can shatter the delicate leaves of forages like clover and alfalfa, reducing the hay’s protein content. For straight grass hay, this is less of a concern, and the mower’s speed and reliability make it a top contender.

I&J Ground-Drive Mower for Low-Horsepower Use

What if you don’t have a PTO on your tractor, or you want to use an ATV or even a team of horses to cut hay? The I&J ground-drive mower is a brilliant piece of modern engineering based on a classic design. It requires no external power source; the mower’s wheels turn a series of gears that drive the sickle bar.

This machine makes haying possible for those with sub-compact tractors, UTVs, or anyone looking to reduce their reliance on hydraulics and PTOs. Built by an Amish company in Pennsylvania, they are known for their high-quality construction and durability. It’s a specialized tool that fills a critical gap in the small-farm equipment market.

This is not the cheapest or fastest option. A new I&J mower is a considered purchase, and its cutting speed is limited by your ground speed. But for those with unique power constraints, it’s a game-changing piece of equipment that unlocks the ability to make your own high-quality hay efficiently and sustainably.

Sourcing and Maintaining Your Compact Windrower

Finding the right used mower requires patience. Keep an eye on local farm auctions, Craigslist, and Facebook Marketplace, especially in late fall and early spring. When you inspect a machine, look beyond the paint. Check for cracks or welds on the frame, feel for excessive play in bearings and pivot points, and sight down the cutter bar to ensure it’s straight.

Once you own it, maintenance is key. For a sickle bar, this means keeping a supply of spare sections (blades) and guards. Learn how to replace them and how to properly register the blade for a clean cut. For drum or disc mowers, regularly check the gearbox oil and the condition of the blades, replacing them before they become dangerously worn.

Before you hand over any cash for a used machine, do a five-minute search on your phone for parts. Can you easily buy blades, belts, or guards for it? If the answer is no, you should probably walk away. A cheap machine becomes an expensive piece of yard art the first time a critical, irreplaceable part breaks.

Ultimately, the best windrower for your five acres is the one that gets the job done reliably, season after season. It’s a balance of cost, capability, and compatibility with the rest of your homestead’s systems. By matching the machine to your specific piece of land and your available power, you can turn the chore of haymaking into one of the most productive and satisfying jobs on the farm.
