6 Best Square Balers For Small Tractors That Small Farmers Swear By

That feeling of watching a perfect field of hay get rained on while you wait for the custom baler is something most small farmers know too well. It’s a frustrating loss of control over your own harvest and your animals’ winter feed. Owning your own small square baler changes the entire equation, putting the power to beat the weather back in your hands.

Why a Small Square Baler is a Game-Changer

Owning your own baler is about one thing: independence. You’re no longer at the mercy of a custom operator’s schedule, trying to squeeze your five acres in between their 100-acre clients. When your hay is cured and a storm is on the horizon, you can go bale. That’s it.

This control transforms how you manage your fields. You can bale smaller plots that a commercial operator would ignore. You can also fine-tune your timing to maximize the nutritional quality of your forage, cutting and baling at the absolute peak moment.

The bales themselves are another major advantage. Small squares are manageable. You don’t need a big tractor with a front-end loader to move them; a strong back or a simple dolly will do. This makes them perfect for feeding a few goats, sheep, or a horse without the hassle and potential waste of a giant round bale.

New Holland Hayliner 273: The Classic Workhorse

If you see an old, reliable-looking baler sitting in a field, there’s a good chance it’s a New Holland. The Hayliner 273 is an absolute legend for a reason. It’s a simple, mechanical machine that requires relatively low horsepower—a well-maintained 35 HP tractor can handle it on flat ground.

The beauty of the 273 is its simplicity and the sheer availability of parts. These balers were made for decades, and nearly every farm mechanic knows how to work on their Super-Sweep pickup and Flow-Action feeding system. The knotters are straightforward and, once timed correctly, will tie bale after bale without complaint.

Of course, you’re buying a piece of history. Most 273s have seen a lot of work, so a thorough inspection is critical. But for a farmer who isn’t afraid to turn a wrench and wants a machine that just plain works, it’s hard to beat the value and proven track record of this classic workhorse.

John Deere 338: Reliable and Widely Available

The John Deere 338 is another cornerstone of small-scale haymaking, representing a slightly more modern design than the old Hayliners. It’s known for its robust construction and dependable performance, making it a favorite on the used market. Like the New Holland, it’s a side-pull design, but many operators feel it produces slightly more consistent bales.

What sets the 338 apart is the vast John Deere dealer and parts network. Finding wear items like pickup tines or knotter components is rarely a problem. This is a huge consideration when you’re in the middle of baling and something breaks; getting back up and running quickly is paramount.

This baler does require a bit more tractor, typically in the 40-45 HP range, to run comfortably. It’s a heavier, more stoutly built machine. For someone with a capable tractor who values reliability and easy parts access, the 338 is a fantastic, long-term investment that will put up hay for years to come.

Massey Ferguson 1840: Modern Inline Efficiency

The Massey Ferguson 1840 represents a significant shift in baler design. Unlike traditional side-pull models, this is an inline baler. The hay flows straight from the pickup into the chamber, which has two major benefits: it reduces leaf shatter for more nutritious hay, and it tends to create denser, more uniform bales.

This design is particularly great for delicate crops like alfalfa, where preserving the leaves is key to feed quality. The straight-through path is simply gentler on the hay. The MF 1840 is also known for being a compact and maneuverable machine, making it ideal for smaller, irregularly shaped fields.

The tradeoff is complexity and cost. Inline balers are generally newer and more expensive on the used market. While highly reliable, their systems can be more intricate than older side-pull designs. This is a premium choice for the small farmer who prioritizes bale quality and modern efficiency.

Abbriata M60 Mini: For Ultra-Compact Tractors

For a long time, if you had a sub-compact tractor under 25 HP, making your own square bales was just a dream. The Abbriata M60 Mini changed that. This Italian-made baler is specifically designed for low-horsepower applications, capable of being run by tractors with as little as 18-20 PTO horsepower.

This is a true game-changer for micro-farms, homesteads, or anyone managing just a few acres with a compact utility tractor. It produces a smaller, lighter bale—around 30-40 pounds—which is incredibly easy to handle by hand. It’s perfect for feeding small livestock without waste.

The M60 is a specialized piece of equipment. It won’t have the capacity of a standard baler, and parts might be less common than for a Deere or New Holland. But for the right operator with the right tractor, it opens up a world of self-sufficiency that was previously out of reach.

Hesston 4550: The Small Inline Powerhouse

Hesston has a legendary reputation in hay equipment, and the 4550 is a perfect example of why. This is another small inline baler, often seen as a direct competitor to the Massey Ferguson 1840. It’s prized for its ability to make exceptionally tight, well-shaped, and heavy bales.

The 4550 is a compact machine that packs a serious punch. Its inline design is efficient, and its knotter system is widely regarded as one of the most reliable in the business. If your goal is to produce top-tier, "show quality" hay in a small square format, the Hesston is a machine to look for.

Like other inline models, the 4550 will command a higher price and requires a bit more horsepower than the old classics, usually around 35-40 HP. It’s a machine for the serious hobby farmer who sees haymaking not just as a chore, but as a craft.

Case IH SB531: A Simple, Dependable Choice

The Case IH SB series balers are the quiet, dependable cousins in the small baler family. The SB531 is a solid, side-pull baler that embodies a no-frills approach to getting the job done. It’s built on a proven design that is both effective and relatively easy to maintain.

Think of the SB531 as a straightforward, mechanically simple machine. It doesn’t have the advanced features of a modern inline, but it also doesn’t have the associated complexity. For a farmer who values rugged simplicity and just wants to make good, consistent bales without a fuss, it’s an excellent option.

Parts are readily available, and the operating principles are common to most side-pull balers of its era. It’s a great middle-ground choice that offers reliability without the high price tag of newer inline models, making it a smart buy for many small operations.

Key Features to Check on a Used Small Baler

Buying a used baler can feel intimidating, but focusing on the key wear points will tell you most of what you need to know. Don’t get distracted by faded paint; look at the parts that do the work. A well-maintained older machine is always a better bet than a neglected newer one.

Here’s a practical checklist of what to inspect before you buy:

• Knotters: This is the heart of the baler. Look for excessive wear, grooves, or broken parts on the billhook and knife arm. Ask to see it cycle by hand; it should move smoothly. Rusty or seized knotters are a major red flag.
• Plunger and Knives: The plunger compresses the hay. Check that it runs smoothly in its guides. Inspect the plunger knife and the stationary knife. They should be sharp and properly gapped, like a pair of scissors. Dull or damaged knives make the tractor work harder and produce ragged bales.
• Pickup Tines: Look for broken or missing tines on the pickup reel. These are cheap and easy to replace, but a large number of missing ones suggests general neglect.
• Timing: The baler is a symphony of moving parts. The needle, plunger, and knotter must all be in perfect time. If the timing is off, you risk catastrophic damage, like the plunger smashing into the needles. Ask the seller if the timing has ever been an issue.
• Tires and Frame: Check the tires for dry rot and the frame for cracks, especially around the tongue and axle. A cracked frame can be a sign of a hard life and is often difficult to repair properly.

Ultimately, the best baler is the one that matches your tractor, your budget, and your mechanical comfort level. Whether it’s a classic New Holland 273 you can fix with a wrench and some grit or a modern inline Massey for perfect alfalfa, the right machine grants you control over your most valuable resource: your feed. Choose wisely, and you’ll never have to watch a perfect hayfield get rained on again.
