Pitching Mounds With Wheels: What to Check Before You Buy

A pitching mound with wheels sounds simple: roll it out, throw, roll it back. But the wheels are only one part of what makes a portable mound easy to live with. How it folds, where the weight sits, what the wheels do while your pitcher is throwing, and what the mound looks like when it's put away all matter just as much. This guide walks through what to check before you buy a portable pitching mound with wheels, so the one you bring home actually gets used.

Why Buy a Portable Pitching Mound With Wheels?

Quick answer: Portability and Reps. A wheeled pitching mound lets one person move a full-length mound without lifting its full weight. The idea makes all the sense in the world, reduce the weight and put wheels on it to make life a little easier. When life is a little easier you get more reps, and more reps are what elevate your game.

With that knowledge it's easy to understand how weight is the problem that stands between you and more reps. It's the reason most practice mounds end up leaning against a garage wall. A mound that takes at least two adults to carry only gets used when two adults are around. A pitching mound that one parent or coach can roll out alone gets used on a Tuesday night. If your pitcher will practice in a backyard, at a park, or at the field before games, wheels are usually what make that happen.

A good example of true portability are Leadoff Baseball's wheeled pitching mounds. Their wheeled mounds are hinged and fold to significantly reduce the footprint for easier transport. These pitching mounds roll on large detachable 12" wheels, and the 91-lb FirstStrike rolls and feels like an easy 35 lbs! The 113-lb Velocity feels like rolling 51 lbs. With manageable weight and smooth rolling wheels it's hard to believe that they both are small enough to fit in most SUVs found on the roads in the U.S. Keep reading to learn more about what to check before you buy.

 

How is that possible? It's fancy engineering and physics at play, but the long and short of it is called perceived weight. This calculates the physical effort required to pull or push. That is amazing, but it doesn't stop there - both fold small enough to fit in most SUVs.

What to Check on the Wheels Themselves

Quick answer: Check the wheel size, how and where the wheels attach, and whether they have an internal bearing. Bigger wheels roll more easily over grass and uneven ground. Wheels that detach keep trip hazards out of the picture while your pitcher throws and make it smaller for when the mound needs loaded in a vehicle or stored out of the way. Leadoff wheeled mounds use 12" Stow & Throw™ wheels with quick-release pins.

Wheel type & size

There are so many kinds of wheels, but make no mistake they are not all created for the same reason. Small caster-style wheels work on a hard surface like a smooth garage floor, but they struggle everywhere else. While they seem great at first look because they are rated for a lot of weight and small enough not to be nuisance, most of these small caster style wheels are hard and thin. They sink in soft ground under the weight of almost anything. For a portable pitching mound that is often used in backyards, outfield grass, traveling through gravel lots and navigating curbs or the lip of a driveway - well, these activities all reward a larger wheel. 

What about an inflatable wheel? These are almost sure to let you down at the worst possible time. Think of hand trucks (aka a dolly) or even wheel barrows. The inflatable wheel is really nice, except they never seem to keep their air very long. Nothing worse than wheeling your pitching mound all the way out to a baseball diamond, only to find it's flat when practice is over! Remember this is about getting those reps in, not finding an air pump to do tire maitenance.

For this reason we recommend solid style wheels. Something that is hard and durable, but won't break the bank. Once thing to point out is there are a lot of lawn mower style type of wheels out there that are truly hard and plastic all the way through. However, more often than not they do not have an internal bearing. That's the little metal part that makes a wheel roll smooth, even while under a heavy load. When the wheel does not have a bearing that stick and struggle to do their job, which is roll and make life easy.

Additionally, the wider the wheel the less opportunity it has to fall in a narrow crack in the ground or a parking lot. It really helps displace the weight of the pitching mound over a larger surface so it doesn't sink. We've been there, we tested this out and trust us it's a struggle nobody wants before or after a practice.

So that leaves us with the size of the wheel itself. You have run to the big box hardware store and find inflatable tires (that never seem to have air), you can find casters of all sizes, and of course you can find the little lawn mower wheels (those are so tempting) because they are inexpensive and made for the outdoors. We commonly find these without a bearing in the 5 and 6 inch range. Trust us, these too will sink in soft ground and when you put real weight on the wheel you'll be dragging a pitching mound where ever you want to take it. 

Here are a few reasons why larger wheels are important: 

• Lower rolling resistance: A bigger wheel creates a gentler contact angle with the ground, making it much easier to push or pull—especially when starting from a dead stop. 
• Better obstacle navigation: Larger wheels roll smoothly over cracks, extension cords, floor thresholds, and small debris instead of getting stuck.
• Higher load capacity: They spread the weight of the cart over a wider area, supporting heavier loads.

Before you buy, ask how the mound will reach the spot where your pitcher throws, not just where it's stored.

How the wheels come off

A wheel that stays bolted on can get in the way during a bullpen or make the folded mound bulkier in the back of your SUV. Look for designs where the wheels remove quickly without tools. Leadoff Baseball's Velocity Wheeled 8-Inch Portable Pitching Mound and FirstStrike Wheeled 6-Inch Portable Pitching Mound use quick-release pins with their Stow and Throw wheel system. The wheels come off for throwing or packing, stored right on board underneath the pitching mound, and go back on when it's time to move the mound. The other very unique piece of a Leadoff Baseball wheeled mound is they actually have a wheel axel. Most portable mounds that have wheels are using a shoulder bolt that requires 2 tools to bolt the wheel on. In the case of the Leadoff mounds they use the quick release pins that secure safely to the wheel axel with the push of a button. The wheel axel in this case also helps distribute the weight of the pitching mound evenly to the wheels. That's why they are often called the most portable mounds on the market! 

Is a cart sold separately?

Some portable mounds don't have wheels at all and rely on a transport cart, and those carts are often sold separately for $1,000 or more. Techinically, they are permanent structures so they are still called portable, but if you have to buy a whole cart to move them would you call them portable? Not to mention if the price you're comparing doesn't include a way to move the mound, add that cost before you decide. For a full look at what portable mounds really cost, see How Much Does a Portable Pitching Mound Cost?

How It Folds and What It Weighs When You Move It

Quick answer: Look at the folded size, the hinges and the rolling weight, not just the total weight. A mound that folds and balances over its wheels is far easier to handle alone. This isn't achieved with someone eyeballing the perfect balance point either - it's engineered to find the optimal point. The FirstStrike pitching mound folds to 40" × 30" × 13.5", and the Velocity folds to 40" × 39" × 18".

• Folded size: Measure your vehicle or storage spot before you buy. A folded size listed in all three dimensions tells you far more than a general description like "compact."
• Hinges: The hinge carries the load every time the mound opens and closes. Leadoff wheeled mounds use flush-mount 316 stainless steel hinges that sit flush with the surface. We've seen pitching mounds that are using regular door hinges, and while we applaud the ingenuity they rust and have a large knuckle that sticks out on the field of play. Needless to say, hinges shouldn't become a folding and tripping hazard.  
• Rolling weight vs. total weight: Total weight tells you what the mound weighs. Rolling weight tells you what it feels like to move. With the wheels on, the FirstStrike (91 lbs) rolls like about 35 lbs and the Velocity (113 lbs) rolls like about 51 lbs.

If the mound will travel to games or practices, our guide to finding an SUV-friendly portable pitching mound covers loading and packing in more detail.

Does the Mound Still Throw Like a Real Mound?

Quick answer: Portability shouldn't cost you the a regulation slope. Check that the folding design keeps a true 1-inch-per-foot drop, a real pitching rubber and enough length for your pitcher's stride. Every Leadoff Baseball pitching mound is built to the regulation 1-inch-per-foot slope. You may also notice Leadoff Baseball mounds don't fold into three equal sizes. If you want a larger pitching mound to do that, the only way is to cheat the slope, or make the mound too short for an elite pitcher's stride.

Some folding mounds are built from two equal halves to make folding easy. That can flatten or break the slope in the middle. Ask how the slope is built, and check the length against your pitcher's age:

• Ages 10 and under: 6" rise. The FirstStrike is 40" × 90" (7.5 ft).
• Ages 11–13: 8" rise. The Velocity is 40" × 108" (9 ft) and rated to 350 lbs.

Surface, Materials and Weather

Quick answer: A wheeled mound gets moved, set down and rolled across rough ground, so the build has to handle it. Leadoff mounds are made from exterior-grade Baltic birch (the strongest plywood available) with stainless hardware and come with a Signature rubber or Premium Durable Turf surface. The turf version is a little more because a premium turf is required to be comparable with our shock absorbing Signature rubber surface.

Think about where the mound will live. A mound that rolls between a garage and a backyard, or rides to the field in the car, picks up dirt, dew and the occasional bump. Exterior-grade materials and stainless hinges and pins are built for that. Choose the surface your pitcher will get the most out of - again, in all this talk about features and specifications, the goal is more reps!

Which Leadoff Wheeled Mound Is Right for You?

Quick answer: Choose by age first. The FirstStrike (6") fits pitchers 10 and under and starts at $750. The Velocity (8") fits ages 11–13 and starts at $850. Both have wheels, fold in half and include shipping. For ages 14 and up, the 10" Prospect is modular instead of wheeled and breaks into three pieces.

• FirstStrike Wheeled 6-Inch Portable Pitching Mound ($750) or FirstStrike Wheeled 6-Inch Portable Turf Pitching Mound ($850)
• Velocity Wheeled 8-Inch Portable Pitching Mound ($850) or Velocity Wheeled 8-Inch Portable Turf Pitching Mound ($950)
• For older pitchers: Prospect 10-Inch Modular Pitching Mound ($950). It breaks into three pieces of 44, 49 and 42 lbs, sets up without tools and stacks to 44" × 45" × 23".

Every Leadoff mound is designed, engineered and built in the Kansas City metro. See the full lineup in the Leadoff Baseball portable pitching mounds collection.

FAQ: Pitching Mounds With Wheels

Can one person move a wheeled pitching mound?

Yes, that's the point of the wheels. With the wheels on, the FirstStrike rolls like about 35 lbs and the Velocity like about 51 lbs, so one adult can roll either mound from the garage to the yard or across a parking lot.

Do the wheels stay on while my pitcher throws?

On Leadoff wheeled mounds, the 12" Stow & Throw™ wheels detach with quick-release pins, so you can take them off for throwing and put them back on to move the mound.

Will a wheeled pitching mound fit in my car?

Leadoff wheeled mounds fit in most SUVs. Measure your cargo area against the folded size first: 40" × 30" × 13.5" for the FirstStrike and 40" × 39" × 18" for the Velocity.

Is there a wheeled mound for high school pitchers?

Our 10" mound for ages 14 and up, the Prospect, is modular instead of wheeled. It breaks into three pieces, each under 50 lbs, so one person can carry it in trips and set it up without tools.
