6 Best Wheel Weights For Lawn Tractors On Slopes Old Farmers Swear By
Improve your tractor’s stability on slopes and prevent tipping. We review 6 farmer-approved wheel weights for essential safety and maximum traction.
That feeling of one rear wheel starting to slip as you mow across a hillside is enough to make your heart jump into your throat. Suddenly, a routine chore feels dangerous. For anyone with property that isn’t perfectly flat, a lawn tractor can feel tippy and lose traction right when you need it most. This is where old-timers knew the secret: adding weight, or ballast, is the key to safety and control.

Adding Ballast: A Farmer’s Guide to Stability
Adding weight to your tractor isn’t just about making it heavier. It’s about lowering its center of gravity. Think of it like a pyramid; a wide, heavy base is much harder to tip over than something tall and skinny. By adding weight low down on the rear axle, you anchor the machine to the ground, dramatically improving its stability on slopes.
This added weight does two critical things. First, it increases the friction between the tire and the ground, giving you the grip needed to climb hills or pull a loaded cart without spinning your wheels. Second, and more importantly, it makes the tractor far less likely to roll over. That extra ballast fights the tipping force when you’re on a sidehill.
There are two main ways to add this crucial weight: solid cast iron weights that bolt onto your wheels, or liquid ballast that fills the tires themselves. Each has its place, and the right choice depends on your tractor, your property, and how you use your machine. We’re not just talking about performance here; we’re talking about fundamental safety.
John Deere 50-lb Cast Iron Weights (BG20027)
If you run a green machine, these are the gold standard for a reason. John Deere’s 50-pound cast iron weights are designed to integrate perfectly with their 100, S240, X300, and X500 series tractors. There’s no guesswork involved; the bolt pattern lines up exactly, and the fit is snug and secure.
Made of solid cast iron, these things are built to outlast the tractor itself. You bolt them on and forget about them. That 100 pounds of extra ballast (50 lbs per side) makes an immediate, noticeable difference in stability and traction. It’s the kind of simple, robust engineering that just works.
The only real drawback is their specificity and cost. They are premium-priced and designed only for John Deere wheels. But if you’ve already invested in a Deere, investing in the proper weights is a smart move to protect both you and your machine.
Arnold 55-lb Universal Wheel Weights (490-241-0010)
Not everyone owns a John Deere, and that’s where universal weights come in. Arnold has been making reliable aftermarket parts for years, and their 55-pound universal weights are a solid choice for a wide range of brands, including Cub Cadet, Husqvarna, and more. Their main selling point is versatility.
These weights come with mounting hardware designed to accommodate different bolt patterns. This is a huge advantage if you have an older tractor or a less common brand where manufacturer-specific weights are hard to find. At 55 pounds each, they provide a substantial 110 pounds of ballast to keep you planted.
The tradeoff for "universal" is that the fit might not be as perfect as a factory option. You may have to spend a little more time with the installation to get them centered and tightened down correctly. However, for the price and flexibility, they offer an excellent solution for adding serious stability to almost any lawn tractor.
Cub Cadet 50-lb Wheel Weights for Serious Grip
Cub Cadet owners know their machines are built for tough work, and these 50-pound wheel weights are designed to match. Just like the Deere weights, these are engineered specifically for Cub Cadet tractors, ensuring a perfect fit on XT1 and XT2 Enduro Series models. This eliminates any wiggle or vibration you might get from a universal set.
Adding 100 pounds directly to the drive wheels transforms how the tractor handles slopes and attachments. When you’re pulling a heavy aerator or a cart full of firewood, these weights prevent the front end from getting light and keep the rear tires from slipping. They provide the grip you need to put the tractor’s power to the ground effectively.
They are a straightforward, bolt-on solution. The installation is quick, and the results are immediate. For a Cub Cadet owner tackling hills or heavy-duty chores, these weights are a non-negotiable upgrade for both performance and peace of mind.
Husqvarna 55-lb Wheel Weights for Rugged Terrain
Husqvarna tractors have a reputation for being rugged and capable, and their wheel weights live up to that name. At 55 pounds apiece, they offer a bit more ballast than the 50-pound standards from other brands. That extra 10 pounds across the axle can be the difference-maker on particularly steep or slick terrain.
These are, of course, designed for a seamless fit on Husqvarna-brand tractors. The secure mounting ensures all that weight is working to your advantage, keeping the tires firmly in contact with the ground. This is especially important when using a snowblower attachment in winter, where traction is everything.
The durable coating protects the cast iron from rust, ensuring they look good and perform well for years. If you’re running a Husqvarna on challenging property, these weights are the most effective way to unlock its full potential and operate it safely.
Rim Guard Beet Juice: The Non-Corrosive Solution
Liquid ballast is a completely different approach to the same problem. Instead of bolting iron to the outside of the wheel, you fill the tire itself with a heavy liquid. For decades, the go-to was calcium chloride, but it was incredibly corrosive and would rust out steel rims. Rim Guard is the modern, superior solution.
Made from a byproduct of sugar beet processing, Rim Guard is non-toxic, biodegradable, and non-corrosive to your wheels. It’s also significantly heavier than water (about 11 lbs per gallon) and won’t freeze solid in all but the most extreme climates. Filling a standard pair of rear tractor tires can easily add 100-150 pounds of ballast right where you need it.
The primary downsides are installation and permanence. You need a special pump to get it into the tire through the valve stem, so it’s often a job for a tire shop. Once it’s in, it’s in for good. But for a dedicated work tractor that always needs maximum stability, it’s a fantastic, cost-effective, set-and-forget option.
Agri-Fab 70-lb Wheel Weights for Heavy-Duty Use
Easily haul heavy loads around your yard with this 700 lb. capacity tow-behind cart. The foot-lever release and 80° swivel make dumping quick and efficient.
When 50 or 55 pounds per wheel just isn’t cutting it, Agri-Fab offers a heavy-duty alternative. Their 70-pound wheel weights are for serious applications. This is the kind of weight you need when you’re using ground-engaging attachments like a small plow, disc, or box blade with your garden tractor.
Adding a total of 140 pounds of ballast provides the immense traction required to keep the wheels from spinning when you’re trying to pull an implement through the soil. It’s also a solution for people with very large, heavy tractors or those operating on dangerously steep inclines where maximum stability is the top priority.
Before buying weights this heavy, you must check the maximum axle weight rating for your tractor. All that extra weight puts a lot of stress on the axle and transmission. But for the right machine and the right job, these Agri-Fab weights provide an unmatched level of grip and control.
Cast Iron vs. Liquid Ballast: Which is for You?
Choosing between traditional cast iron weights and a liquid ballast like Rim Guard comes down to a simple tradeoff: flexibility versus maximum weight for the cost. There is no single "best" answer, only the best answer for your situation.
Cast iron weights are simple and versatile. You can bolt them on in the fall for pulling a cart and take them off in the summer for a lighter footprint on the lawn. They can be moved to a new tractor if you upgrade. Liquid ballast, on the other hand, is a more permanent solution that offers more weight per dollar, but it can’t be easily removed.
Here’s a simple framework to help you decide:
- Choose Cast Iron if: You switch between light and heavy tasks, want to remove the weight seasonally, or plan on selling your tractor eventually.
- Choose Liquid Ballast if: You need maximum traction and stability year-round, you have a dedicated "workhorse" tractor, and you want the most cost-effective weight solution.
For many hobby farmers, having a set of cast iron weights provides the perfect balance of performance and flexibility. But for a machine that lives on a hillside or is constantly pulling heavy loads, filling the tires with Rim Guard is an incredibly effective and economical choice.
Ultimately, adding ballast to your lawn tractor is one of the most significant safety and performance upgrades you can make. It transforms a tippy, traction-limited machine into a stable and capable workhorse. Whether you choose the convenience of cast iron or the sheer heft of liquid ballast, getting that center of gravity low to the ground will give you the control and confidence you need to work your land safely.
