We tested four of the best new mowing machines on a high-grade incline and a few grateful neighbors' yards. The takeaway: The right equipment transforms cutting the grass from boring chore to the highlight of your weekend. LIKES: This is the first tractor at this price to have electronic fuel injection, which reduces fuel use by producing a more precise air-to-fuel ratio than you get with a carburetor.
It also makes for consistent starts and high performance regardless of weather or fuel quality. We liked the push-button start, responsive steering, and tight cutting radius. It's also our test's most comfortable ride. By far. The cut quality is excellent, and the cutting radius tied with the Cub Cadet's as the tightest we tested.
Anything more than 30 minutes on this one leaves you a little sore. It had no traction problems, uphill or down. We also liked the float-lever gas gauge, which, unlike the other machines that make you decipher hatch marks on a cloudy tank, is easy to read while you're driving. Its Kohler engine has plenty of power and the locking rear differential made the most of it, especially in the neighborhood's steep-walled drainage basin. It's comfortable, too, and not just for a tractor. Type keyword s to search.
Today's Top Stories. Advertisement - Continue Reading Below. Gregg Delman. Craftsman Pro Series T Deere S Sport. Husqvarna YT46LS. More From Tools.Fifteen years ago the power output of every snowblower sold here in the United States was listed in hp or horsepower.
It was a nice simple measurement that everyone in the U. Ten years ago they changed the rules and started selling snowthrowers with the power measured in gross torque. Then they changed the rules on us again. Today, Sept only a few Chinese manufacturers still list HP on the engine shroud. Other manufacturers like Powermore may have different torque ratings for their motors.
If you are trying to get exact hp measurements you should research the torque ratings for the specific brand. Here is a simple chart of approximate cc to torque to horsepower conversions. I used rpm in the formula for this comparison. Assume that your new snowblower motor runs at less rpm. It is also not a good comparison from one manufacturer to another.
I hope this helps. Here is an original article on this issue: Horsepower loses its grip on mowers. When you buy lawn and garden equipment this spring, a familiar old term —- horsepower —- will be missing from many engines. Blame it on lawyers, or engine makers who might have fudged the numbers, but horsepower is no longer the gold standard for small gasoline engines.
Sears, for example, advertises some lawn mowers rated by horsepower, others by torque, and still others by cubic centimeters. And some mowers have no such designation at all. Last year, Briggs chose torque as its rating system for push mowers, snow throwers, pressure washers, and generators. In basic terms, torque is a measure of the force needed to turn something like a wrench or a lawnmower blade. Horsepower, on the other hand, evolved from a measure of the rate at which a horse could pull coal up a mine shaft into a more technical measurement related to watts.
So now, consumers may face confusion over how torque equates to horsepower. The shift away from horsepower ratings came after a lawsuit in Illinois claimed that engine manufacturers were overstating the horsepower of lawn mower engines.
In some cases, the lawsuit alleged, identical engines were labeled with different horsepower ratings, misleading consumers into believing they were getting more power by purchasing more expensive models.CC, or cubic centimeters, is a measurement of volume or size. Engine horsepower is a measurement of power output at certain rotation frequencies.
How to Convert Engine Horsepower to CC
Rotation frequencies are measured in revolutions per minute, or rpm. Engine horsepower cannot be directly converted to cc because horsepower is measured at rpm levels that cubic centimeters do not account for. While no specific formula for the conversion of engine horsepower to cc exists, on average 1 horsepower equals 16 cc. Determine your engine's peak horsepower.
An engine's peak horsepower is typically measured at a certain rpm level. Drop the rpm figure from the horsepower figure. For example, if your engine achieves horsepower at 6, rpm, drop 6, and use for your calculation. Use a calculator to multiply your engine's horsepower by This figure represents your engine's horsepower in cubic centimeters.

The CC indicates the volume of gas V swept by the piston in the combustion chamber during each powerstroke. To know the brake power, whose unit is horsepower, BPyou must also know the frictional power FPengine rpm N and combustion chamber mean effective presure P. You must provide the other details to get the exact answer. The first answer is correct. However you could make a rough correlation based on the current technology in internal combustion technology.
Unfortunatly I don't know where that stands right now. But I will offer this. Many years ago I was interested in motorcycles and I remember reading that the BSA British Speed Association had a motorcycle engine that was producing one horsepower per cubic in of volume displacement.
EDIT: In bigger engines it looks like you can get more than one horsepower per cubic inch. Maybe around 1. Here is the web page I got this from. Don't you just love the web? The full answer is complex - the power output of an engine depends on the state of tune as well as size, and the definition of horsepower must be considered, brake horsepower bhp or shaft horsepower shpand is not covered here.
Horsepower can be increased by engine tuning, more volatile fuel, supercharging or exhaust turbo boosting. A cc is a cubic centimeter. It is a unit of Volume. A horsepower is a unit of Power. They are not the same thing. There is no fixed relation.Horse Power! Horses, man! And this…is what we refer to as one horsepower. Eventually, the phrase became antiquated when considering actual engine capacity and became more of a catch phrase for salesmen. The bore is the diameter of the circular chambers cut into the cylinder block.
Exact measurements make for a happy engine and a unified measurement system brings everybody on board for the big win. I receive lots of emails asking me to find a blah blah horsepower engine, when the manufacturer no longer uses that measurement.
And, yes there is an equation that will allow one to convert from CC to horsepower. For those of you with a mathematical bent, let me try to sum it up for you.
179cc equals how much in horsepower?
In terms of automobile specifications, 1 horsepower is roughly equivalent to 15 to 17 cubic centimeters. You can often find him creating featured articles, DIY guides, videos, graphics and much more. Skip to content. April 21, Bill Brown. Good question.
Wanna make math fun? I like horses, they have soft, fuzzy noses. The shortest answer is: Metrics. So, there you have it. I suppose when you look at it that way, it all sort of measures up.

Snowblower/mower engine cc to torque to hp conversion 2018 Update
First of all, it's important to note that cc is a measure of engine size, while hp is a measure of how much power it produces. Generally, a larger engine will produce more power, but the ratio isn't uniform across all engines. It depends on how well-tuned the engine is, as well as the type of fuel it uses. Most modern passenger cars, however, do fall into a small range of ratios.
Divide the cc of the engine by For example, the cc of a 1. For example, the Escort's cc divided by 17 yields approximately Recognize the horsepower falls somewhere in the range established by the previous steps. In fact, the Escort's horsepower is Its cc to hp ratio is This article was written by the It Still Runs team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information.
