You’re standing in front of a multi-ton piece of yellow iron, and honestly, it looks a bit intimidating. Maybe it’s a rental. Maybe it’s your first day on a new job site. Either way, figuring out how to start a skid steer isn't just about turning a key and hoping for the best. These machines are quirky. They have safety interlocks that will make you feel like a total amateur if you don't know the "secret handshake" required to get the engine to actually crank.
Every brand has its own personality. A Bobcat doesn't wake up the same way a Caterpillar or a John Deere does. If you jump in and just start hacking at the controls, you’re likely to sit there in silence while the dashboard beeps at you mockingly. It’s frustrating.
Actually, the first thing you have to realize is that these machines are designed to not start unless you are perfectly positioned. Manufacturers like CASE and New Holland have spent millions of dollars ensuring that if you aren't buckled in and ready, that engine stays dead. It's a safety thing, obviously, but it can be a real headache when you're in a hurry to move a pile of gravel before the rain hits.

Why the Safety Bar is Your Best Friend (and Worst Enemy)
Most people climb into the cab, see a key or a "Start" button, and go for it. Stop. You've gotta sit down first. The seat sensor is usually the first line of defense. If the machine doesn't feel your weight, nothing happens. Once you’re in, you have to lower the lap bar.
This bar is the gatekeeper.
In many older Bobcat models, that bar has to be clicked firmly into place to complete the electrical circuit to the starter. If it's hovering even a half-inch too high, you’ll get lights on the dash but no roar from the diesel engine. It’s a simple mechanical check that saves lives, but it’s the number one reason beginners think the battery is dead.
Then there’s the seatbelt. Some modern machines, especially the newer Cat D3 series, are incredibly picky about the sequence. If you put the bar down and then buckle up, it might work. But some software setups require the buckle to click before the system acknowledges the operator is "active." It feels a bit like a logic puzzle.
The Sequence Matters More Than You Think
Let’s talk about the actual ignition. On a cold morning, you can't just crank it. Diesel engines rely on compression and heat. If you’re dealing with a Kubota engine inside that skid steer, you likely have glow plugs.

Turn the key to the "On" or "Run" position—don't go all the way to "Start" yet. Look at the digital display or the analog gauges. You’re looking for a little coil icon. That’s the glow plug indicator. Wait for it to turn off. Sometimes it takes three seconds; on a freezing morning in Minnesota, it might take fifteen. Pushing the starter before those cylinders are warm is a great way to drain your battery and accomplish exactly nothing.
Once that light vanishes, give the key a turn or hit the "Start" button.
It should rumble to life. But you aren't moving yet. This is where people get confused. The engine is running, the exhaust is puffing, but the joystick controls feel like they’re locked in concrete. That’s because the hydraulic lockout is still engaged.
Breaking the Hydraulic Lock
Look for a button that usually says "Press to Operate" or has a picture of a lock. On many machines, this is a bright green button on the upper left or right of the ROPS (Roll-Over Protective Structure) post.
When you press this, you’ll hear a distinct click or a slight change in the engine's hum. That’s the solenoid opening up the hydraulic flow to your loaders and drive motors. Until you hit that button, the machine is basically a very expensive paperweight.
Different Brands, Different Rules
If you’re in a John Deere, the parking brake is often a physical switch on the side panel. It’s not enough to just have the engine running; you have to manually flip that toggle to "Off" or "Release."
Caterpillar machines often use a "dead man" switch style. If you lift your butt off the seat for even a second to grab a water bottle, the hydraulics might lock back up. It’s annoying, but it prevents the machine from rolling away if you happen to tumble out of the cab—which, let’s be honest, shouldn't happen if you're using the three-point contact rule while climbing in.

- Bobcat: Often requires a code on the keypad. No key? No problem, as long as you know the 4-digit or 5-digit PIN.
- Kubota: Very straightforward, but they really want those glow plugs warm.
- JCB: You enter through a side door instead of climbing over the bucket. The starting sequence is similar, but the door must be fully latched.
Troubleshooting the "No-Start" Blues
What if you do everything right and it still won't turn over?
First, check the E-stop. That big red mushroom button? Someone might have bumped it. If it's pushed in, the entire electrical system is cut off. Twist it until it pops out. It sounds stupidly simple, but I’ve seen grown men spend an hour checking fuses only to realize the emergency stop was engaged the whole time.
Check the throttle. Most skid steers should be started at a "low idle" or "half throttle." If the lever is pushed all the way to the "rabbit" (high speed) setting, some safety controllers won't let it fire up because it's a surge hazard. Pull it back to the "turtle."
Lastly, look at the battery disconnect. On many rental units or machines kept on large sites, there’s a physical switch near the engine compartment that cuts the battery power to prevent drain or theft. If the dash is completely dark, that’s your culprit.
Moving for the First Time
Once you've mastered how to start a skid steer, the real fun begins. But don't just jam the sticks forward.
Let the engine warm up for at least two to five minutes. The hydraulic oil needs to circulate. Think of it like a human athlete; you wouldn't sprint a marathon the second you woke up. If the oil is cold, the machine will feel jerky and unresponsive.
Lift the bucket just a few inches off the ground. Never travel with the bucket high in the air—that’s how you tip over. Skid steers have a short wheelbase, making them notoriously "tippy." Keep your center of gravity low, keep your eyes moving, and always be aware of who is standing behind you.
Actionable Steps for New Operators
If you're heading out to the machine right now, follow this mental checklist to ensure you don't look like a rookie:
- Clear the Area: Walk around the machine. Check for leaks or loose bolts. Make sure no one is sleeping in the shade of the bucket.
- Mount Safely: Face the machine. Use the handles. Don't grab the joysticks for leverage—they move.
- The Lockdown: Sit, belt, bar. In that order.
- The Glow: Key to "On." Wait for the squiggly wire light to go out.
- Fire It Up: Turn to "Start."
- Unlock Hydraulics: Find the "Press to Operate" or "Parking Brake" button and toggle it.
- Test the Controls: Gently wiggle the sticks to ensure the bucket responds before you start driving.
Starting a skid steer is really about respecting the machine's internal logic. It wants to be safe. It wants to make sure you're ready. Once you understand that the machine is essentially waiting for your "permission" through those safety switches, the whole process becomes second nature. Just remember: if it isn't starting, you probably forgot a buckle or a button.
Check the E-stop one more time. You'll thank me later.
