Everything You Need to Know About Tractor Ballast


If you’re looking for ways to maximize the performance of your tractor, ballasting is an important method for getting the most out of your machine. In this article we’ll cover all of the essential details you need to know including types of ballast, how to ballast effectively, and the benefits ballasting your tractor can offer.

What is Ballast?

At the most basic, ballast is when a heavy material is used to provide extra stability to a vehicle or structure. It can come in many forms, ranging from sand and gravel to iron weights and water tanks. In a tractor, ballasting is usually used on the rear of the machine to provide extra traction, prevent wheel slipping, and keep all four wheels firmly on the ground when lifting with the front-end loader.

Types of Ballast

There are many different ways you can utilize ballast in your tractor. Depending on the specific task, certain types of ballast might be more effective for meeting your needs than others. Here are some of the most commonly used forms of ballast for tractors.

Ballast Box

A ballast box is a simple, easy-to-use ballasting option. Typically, it’s an empty metal box that attaches to the three-point hitch at the rear of the tractor. Based on the amount of counterweight needed, it can be filled with heavy materials such as gravel or sand.

Suitcase Weights

Suitcase weights are another popular way to add and remove weight to your tractor as needed. Made from cast iron, this type of ballast looks like a rectangular suitcase with a handle at the top that can be slipped onto the hitch. These weights come in a variety of sizes, ranging from 40 to 100 lbs. 

Wheel Ballast

If you want to keep your three-point hitch free, wheel ballast can be used to achieve the same results as a ballast box or suitcase weights. Instead of attaching cast iron weights to the rear of the tractor, they’re attached to the rear wheels themselves. One of the downsides is wheel weights can be difficult to remove if you need to change them out regularly. 

Liquid Ballast

Liquid ballast can be considered another form of wheel ballast. This method fills the rear wheels of the tractor with a liquid to lower the center of gravity and improve traction. Common types of fluids used for liquid ballast include water, calcium chloride, antifreeze, windshield washer fluid, and even beet juice.

Front Ballast

Though ballast is usually applied to the rear of the machine, there are certain situations where a front ballast might be required. For example, using a heavy tractor attachment at the rear without having the front-end loader attached. Fortunately, the principle is the same and this can be achieved through common options like suitcase weights.

4 Benefits of Ballasting Your Tractor

With an understanding of the different ballast options for your tractor, there’s nothing left to do but start implementing them and improving your performance. Here are four of the key benefits you can expect from ballasting.

Improved Stability

Perhaps the biggest benefit of ballasting is the increased stability it provides. With even weight distribution, the tractor’s center of gravity is lowered. This provides better control over the machine, especially when working on rough or uneven terrain.

Better Traction

Proper ballasting can also help improve the performance of your tractor’s four-wheel drive traction. Added weight increases the tire’s contact with the ground, better transferring torque to the wheels. This is especially valuable in preventing slipping on surfaces such as ice, mud, or loose gravel and dirt.

Reduced Wear and Tear

Ballasting your tractor is an easy way to expand the machine’s lifespan. If the tractor does not have the appropriate rear ballast when using the front-end loader, it can cause an excessive amount of load and strain to the front axle and tires. With weight more evenly distributed, you avoid this additional pressure on other components.

Increased Efficiency

The right amount of ballast can lead to more efficient performance. When your wheels aren’t slipping or certain components aren’t bearing more strain, your engine also operates more efficiently, reducing overall fuel consumption.

How Much Ballast Should I Use?

The amount of ballast needed depends on your specific tractor, the type of job you’re doing, and the terrain you’re operating on. When in doubt, consult the operator’s manual or your local Yanmar dealer for specific ballasting information.

If you’re unsure of how much ballast weight you need, here’s a quick overview.

Signs You’re Not Using Enough Ballast

  • Wheels slipping frequently
  • Excessive fuel consumption
  • Excessive wear on tires
  • Lack of traction
  • Decreased stability

Signs You’re Using Too Much Ballast

  • Excessive ground compaction
  • Strain on tires and wheels
  • Feeling of lower tractor power
  • Excessive fuel consumption
  • Decreased stability and reduced ride comfort
  • Unacceptable braking performance
