4 Cycle Snowblowers Why 4 Cycle Engines are the Best
4 cycle snowblowers are snow removal machines that are powered by 4 cycle gas engines, also known as 4 stroke engines. 4 cycle engines are called such because they have a separate stroke each for power, compression, exhaust, and intake. Unlike 2 cycle engines that feature side valves, a 4 cycle can be equipped with either side valves or overhead valves. In snowblowers, you will more commonly see a 4 cycle OHV engine, though.
4 cycle engines are most widely used in two stage snowblowers. Since two stage models are faced with heavier, more demanding snow clearing jobs, they will benefit much from the higher horsepower and greater torque of a 4 cycle engine. So if you’re looking for a two stage model, a 4 cycle engine is highly recommended.
4 cycle engines don’t just provide greater torque and higher horsepower. They also bring other benefits. 4 cycle engines tend to last long than 2 cycle ones, and they don’t require as much maintenance. They are also significantly easier to start. Most importantly, they require only regular gasoline to work. This means you don’t need to mix gas and oil to make the engine run.
For single stage 4 cycle snowblowers with OHV engines, check out the Murray 1695537, a single stage snow thrower with a 4 cycle engine from Briggs and Stratton’s Snow Series. This is a great choice to consider for those looking for a powerful mid-priced and mid-sized single stage machine, thanks to its $400 price tag and its 190cc engine displacement. The machine also has a 21-inch clearing width that helps speed up most tasks by clearing larger paths at once.
The Murray 1695537, however, should only be used in clearing light to moderate snow, with depth of 4 to 6 inches. Although it doesn’t have many advanced snow blowing technologies, it comes with plenty of convenience-focused features, such as a clog resistant chute and a fold-down handle to make storage easy. The fan is also lightweight and users have found it easily maneuverable.
For those looking for two stage 4 cycle snowblowers, one of the best options available is the Yard Machines 31A-32AD700. This is not the fastest nor most powerful snowblower, especially with its 179cc engine displacement. Based on this, the machine is no match for the higher engine displacement ratings of some single stage snow blowers. Still, reviews for this two stage 4 cycle snow blower with an OHV engine are quite positive, especially since it is one of the cheapest two stage blowers with its price of $650.
This self-propelled two stage snow thrower is recommended for those looking for a compact but powerful two stage machine. Keep in mind, though, that the machine only has a 22-inch clearing width, making it one of the smallest two stage blowers around. Thankfully, its gas engine provides optimum power and performance without requiring a gas and oil mixture. The auger and impeller are 9 and 10 inches respectively, so they are more capable than the smaller ones featured in single stage blowers.
Thankfully, this machine also as plenty of user convenience features to offer, such as a 180 degree rotating chute made of rugged polymer for durability, an oversized mitten grip handle, and 10-inch pneumatic tires.
Poulan Pro is one of the most trusted snow blower manufacturers around. Their two stage snow blowers are highly reputable for power and reliability. But the brand also offers a popular single stage snow blower that is known for its powerful 4 cycle engine. Among single stage models of 4 cycle snowblowers, this model seems to have the highest engine displacement rating of 208cc.
This is thanks to the LCT 4 cycle gas engine, which is actually rather large. But despite the extra bulk for a single stage model, the Poulan Pro PR621 is quite easy to maneuver. And with the scraper bar, you can clean right down to the pavement without damaging your paved paths.
One of the best things about Poulan Pro is the durable construction of its machines. This model comes in a fully welded steel body with E-dip paint, so it’s durable and protected enough for even the toughest winters.
This is a great choice for those looking for a highly capable machine of this size, which is 21 inches in terms of clearing width, but don’t want to spend for a two stage model since your needs only call for a single stage model.
Why 4 Cycle OHV Engines Are Preferred?
The common type of gas engines used in snow blowers, especially two stage models, is the 4 cycle OHV. An OHV engine refers to one that has an overhead valve. The configuration of an OHV engine is different from the side valve configuration of most 2 cycle engines.
In an OHV engine, the fuel and the exhaust enter and leave the engine from a valve located on top of the machine, hence the name overhead. This configuration allows engine packaging to be smaller and also simplifies the drive system. This helps lessen the possible problems that may come up with regards to the engine, helping keep your snow blower trouble-free.
