Rated 4 out of 5 by from * * * * Starts easy and runs strong. Starts each spring with 1 pull. however first summer with very few hours on it it just quit. it would not start. Took it in for repairs, which were covered under warranty, and the PLASTIC cam shaft broke!!!!! who makes a camshaft out of plastic???? The replace ment was still plastic but different material. the machine has run for 3 years now no problems. hopefully B/S has changed the material on this part.

Rated 1 out of 5 by from Won't stay running I upgraded to a 6.75 so I would have more power on my log splitter to run the hydraulics, but when head into the log it quits it is very frustrating to have to keep starting it, even with easy splitting logs. It is not a cheap motor to replace I think it should be better for the money.

Rated 1 out of 5 by from Buyer beware I purchased a TB280ES with 675 series Briggs and Stratton 190cc motor. I used the mower twice deployed to Afghanistan and returned to find that the engine will not start. Followed all of the tips to include replacing the spark plug and fuel to no avail. The problem with the engine is that the carburetor does not allow fuel to reach the engine and since it does not have a priming bulb it is impossible to prime. I called the number provided and was told to return to Lowes. expected of a quality product.

Rated 5 out of 5 by from Just Right for A Push Mower This engine has plenty of power and torque to get the job done mulching, side-discharge or bagging. It have owned this engine on a Snapper mower for 2 years and it does not bog down ever! Easy starting, no worry engine with no ethanol fuel and stabilizer.

Rated 1 out of 5 by from The concept doesn't really make sense This should be a good product on the Brute 22" 3 in 1 self propelled mower. The engine is large and beefy so it would theoretically have plenty of grass cutting power. However there are problems. You have to hold the emergency stop lever (bail control) down so that the engine will stay running. Whoever designed this bail apparently had no consideration for comfort. It hurts your hands after you've been mowing for awhile. This is particularly true because of the way you have to hold the bail while squeezing the drive lever.The side discharge deflector is an extremely cheap piece of plastic that hooks over the hinge for the spring loaded cover that is closed for mulching. I would imagine that the majority of these will get broken after a few seasons. This is even more strange when you consider the excellent quality of the grass catcher. This mower was obviously designed around the rear bagger and they did a good job. However, the side discharge mowing mode seems to be more of an afterthought.However, the worst aspect is the engine. Apparently someone at B&S decided a manual choke or primer bulb was too complicated and came up with the notion of making everything automatic. Now considering that I had no trouble starting B&S engines with manual choke when I was eight years old I don't quite understand the reasoning behind this.Normally you would let the mower idle and then increase to full throttle to mow. However, with the automatic throttle on this product, the engine has no real full throttle setting. Instead it idles slightly fast and then attempts to compensate as you begin cutting and the engine bogs down. In other words, the engine is constantly attempting to reduce throttle and only increases it to stop the engine from dying. This seems somewhat counter-productive with the task of mowing. The auto-choke is also rather baffling. A manual choke works just fine as does a primer bulb. However, this engine uses a somewhat complicated mechanism that holds the choke closed with a spring and then uses an internal wind vane to force the choke open as engine speed picks up. Then it uses a second temperature actuator arm to hold the choke open if the muffler is hot. This somewhat complicated system might be good if it worked but instead it seems to prevent the engine from idling properly.I agree that this mower starts easily. In fact, for an engine of this size it is remarkably easy to start with the pull rope (and a breeze with the electric start). However, it won't stay running. And because of the auto choke and throttle there isn't much the operator can do to compensate. Nor do the B&S engine manuals have any information on getting it to work. I've used many mowers over the years but never one this unreliable. It is possible that something is merely out of adjustment or broken but considering that I would have no trouble tearing this engine down and overhauling it the complete lack of technical information from B&S is aggravating at best. Since the engine is out of warranty I should not have to take it to an authorized repair shop for something that I could do myself. I would imagine that many others feel the same way.Another way of looking at this is that the lack of technical information which would force you to take this unit to a repair shop would somewhat degrade the value since the base price (which seems quite reasonable) would have to be scaled up for potential maintenance.

Rated 2 out of 5 by from automatic choke *ez start* Bought this mower 120 days ago, so I am not even able to return it to the store (has a 90 day return policy) I bought it from. The ez automatic choke start keeps flooding the engine so that it won't start. Did all of the trouble shooting recommended in the manual, to no avail.Will say that when it did start it mowed fine. I would NOT recommend this mower to anyone. For the price that I paid, I should have a mower that starts easily and reliably for more than 120 days. Garbage, very disappointed with B&S.

Rated 5 out of 5 by from This is a great reliable engine. I bought my Toro 20090 push mower brand new back in 2009 with this engine on it. I have had nothing but good luck with this engine since day one. It always starts on the first or second pull and has never given me any trouble. I use my mower for about 40 minutes once a week during the mowing season. This engine has very good power in tall grass and its quiet. The sound of the blade spinning under the mower deck is louder than the engine!!!. I also have to say that for a flat head this engine seems to be good on gas. It will be interesting to see what will last longer. The alloy deck on my mower or this engine?. So far both are showing no signs of wear. I always hose off the under side of the mower after I'm done using it. ( Make sure the air filter is facing up when the mower is on its side). Then I wipe down the top of the mower with a soft damp rag to try and keep it clean. I always change the oil, spark plug, air filter and pre-filter at the start of the season. I've only used Briggs 30 weight oil in all my engines since most small engine shops and big box stores sell it
