We know that snowmobiles use motors. The sound says it all. Does this mean the snowmobile is automatic? If it is, how is the gearing as good as manual control?
To find answers to all your questions, read on to know which transmission mechanism works on snowmobiles.
Are snowmobiles automatic or manual?
The transmission on snowmobiles is automatic but it involves a special CVT or continuously variable transmission. CVT uses a step-less system where gear can be varied with the help of a double-clutch. Therefore, snowmobiles are unlike other conventional automatic cars.

Are there automatic snowmobiles?
Many experts argue that a snowmobile is neither entirely automatic nor totally manual. This is because, if you are in the driver’s seat, and have the control, driving the snowmobile is an automatic experience.
However, inside the engine, the machine uses a very specialized transmission system, called CVT or continuous variable transmission. All snowmobiles use this automatic specialized transmission
In a manual system, the driver used his hands and limbs to make the appropriate movements for the stick and pedals, in order to change the directions, accelerate, start or a brake. As the driver controls the gears, force is transferred from the engine.
In contrast, if you drive a conventional automatic car, the mechanical is based on a hydraulic or electronic system that requires you to navigate without any pedals.
Automobiles use a mechanism that is somewhere in the middle, as it is a gearless and stepless mechanism, where the clutch is what transfers the required power.
Is a manual or automatic snowmobile better in the snow?
When it comes to maneuvering your snowmobile in snow-filled terrain, an absolute automatic or manual snowmobile would not be as efficient as a CVT run snowmobile, which can be considered semi-automatic given its characters and working process.
Energy Efficiency:
CVT automated snowmobiles have much greater fuel efficiency than manual or automatic vehicles.
The use of hybrid powertrains for an automated step-less power transfer makes sure that you can travel a lot further or a lot longer. This is especially helpful in deep snow areas requiring higher gears.
Proper gearing:
If the snowmobile is manual, there would be problems regarding what gearing to start at.
Even though a manual transmission is considered to be more controllable in terms of speed and shifting in comparison to complete automatic transmission.
A CVT led snowmobile will balance the best of both, where the gear ratio is varied over a great range. Plus, the speeds are much higher compared to automatic vehicles.
Thanks to the easy change in gearing, your snowmobile will have no issues or limits in shifting gear from 3 to lower or higher in no time.
No sudden changes:
One way a continuous variable transmission is better in the snow is its ability to move on snow hurdles with more consistency.
This means that, when in the snow, your vehicle will not start and stop, or “stutter” on its way. This is because there is no hard shifting in gear change, making the ride very smooth.
When the transmission is manual, many drivers have complained about constant noise when driving in the snow.
This mainly happens when the gear is being shifted from the initial to the second phase. With automatic, there will be the risk of downshifting, unlike CVT.
How does a snowmobile actually function?
A snowmobile’s mechanism involves four parts of the vehicle. This includes clutch, engine, tracks system, and the semi rigid ski portion on the bottom.
At the base of the functions, the power is stored in the engine, which is transferred to the wheels with the help of the clutch.
In a snowmobile, the track drive wheels are connected to the engine itself, converting power directly from the engine to the wheels. As a snowmobile has no limit to the gear ratio, there are no hard shift points when the gears are changed.
As it’s sometimes called, a single speed vehicle, snowmobiles use a double sided pulley system, attached with a chainstay that runs across the entire gear. The pulleys are shaped like a cone, and the end of one is affixed with the shaft while the other is connected to the engine.
If you change the gears in the snowmobile, the movement of these cone-like pulleys change which in turn alters the chain length. As the chain size increases or decreases, the change in gear ratio is transmitted to the wheels.
Do snowmobiles have gears?
Since snowmobiles use continuously variable transmission, the mechanism does not have any gears. In any power transmission system, the drive axle is where the power gets relocated from the main source, the engine.
Why do Snowmobiles not have gears?
Two end pulley system:
In fully automatic vehicles, the gears numbered 1 to 4 are meant to decelerated speeds. If you move the gear to higher numbers, the speed will be higher. A snowmobile does not function in the same way as it is gearless.
Instead, the snowmobile uses a two-sided, cone-shaped pully mechanism to change the chain diameters. The pulley system is such that one end of it is connected directly to the engine and another to the drive shaft.
Efficient Clutch system:
Another reason a snowmobile can have transmission without having gears is because of its clutch system. The primary clutch, which is closer to the crankshaft, works when the speed is low.
When the snowmobile increases in speed, the secondary clutch then gets initiated, and it is connected to the track. When the vehicle is traveling at the most speed, the first clutch shuts down.
This system allows the snowmobile to operate smoothly without hard shifts, lags, or stops.
Do snowmobiles have a reverse gear?
The newer models of snowmobiles are now designed and manufactured with reverse gear. Previously, the reverse gearing option was not incorporated in snowmobiles, making some of the movements in the slow a lot more challenging.
Snowmobiles have two reverse gear options: an electronic reverse gear and a mechanical reverse gear.
How do you put a snowmobile in reverse?
In order to put a snowmobile in reverse, follow the given steps and tips:
Stop the vehicle:
When your RPM is below 4000, only then can you use electronic reverse. For that, at first, you have to bring the vehicle to a stop.
Rest the engine:
Rest the engine on idle for a while. During that time, turn around and clear the area behind you so that you can reverse the snowmobile safely.
Press the reverse button:
The reverse button of the snowmobile is usually located on the left-hand side of the control panel. Press the button briefly. Do not press the button continuously.
Look for the light indicator:
As the RPM is decreased automatically, the reversing mechanism will start. Now, look for the light indicator till the snowmobile is getting reversed.
TIPS: Do not turn on the reverse button when the snowmobile is on, or the engine is in the ignition. If you have to apply the accelerator, make sure to do it gradually. Additionally, you may want to sway away from tight corners.
Do snowmobiles have transmissions?
Snowmobiles have transmissions but they are different from conventional automatic or manual transmissions. This is because snowmobiles use a very specific mechanism known as the CVT or continuously variable transmission.
The mechanism is a step less function that does not have any gear. Instead, a pulley based system is used where the primary and secondary clutch is used to transfer power from the engine to the tracks.
Do snowmobiles have a clutch?
Snowmobiles have two clutches, where one is the primary clutch and the other is a secondary clutch.
The first clutch is located on the drive crankshaft and both are related by a drive belt. As the snowmobile speeds up and torque is produced, the power is transferred from the first clutch to the second.
Consequently, as the second clutch is fastened to work with the track, it transfers power by working the tightening belt.
Is snowmobiling easy?
For beginners, snowmobiling may be a bit challenging. According to snowmobile rides, it took them 5 to 6 rides, before they could drive the vehicle without much struggle.
After a few tries on the ride, one practices and gains experience in how to control the steering, as well as the acceleration or reversing.
Snowmobiles, or snow scooter as it is sometimes called, is a great motorized automobile for having some fun on the snow. The vehicle uses a unique transmission mechanism which makes it neither automatic, not manual.
However, when you are in the driver’s seat, the experience will be as smooth and as easy as an automatic drive.
