Rated 5 out of 5 by from great engine I'm on my seventh season with this engine. I use it year around, mowing and plowing snow with my John Deere tractor. I've never had a bit of trouble with this engine. It starts right up in the coldest weather as well as the hottest weather. Currently I have over 300 trouble free hours.

Rated 5 out of 5 by from No Problems At All! 19hp Intek I've been running this engine with no problems at all since 2006! Lots of use on my TORO Z-Turn! I've been working as a Powered Equipment Mechanic for a long time and we rarely have trouble with these engines.

Rated 4 out of 5 by from Solid Engine So Far I have used this engine on a 2008 Husqvarna ZTR mower for about 3 months now. It has been a very good engine. It starts up everytime, has plenty of power, and does everything I need it to. It also runs smoothly for a single cylinder engine. This engine has helped cut my mowing time by almost half! My only complaint so far is the location of the drain plug.

Rated 5 out of 5 by from Reliable engine I have had this engine on a John Deere D110 tractor for over three months now,and I have not had any problems with it at all. It starts right up and has more than enough power for my needs. For a single cylinder engine it is fairly quiet and I believe the OHV has alot to do with that. It is also very easy on gas,...have mowed several times and still sitting at the "full" mark on the gas gauge,if not just very slightly below it.

Rated 1 out of 5 by from Disposable Engine I've been repairing engines since 1972, and this is one of the absolute worst designs I've seen/worked on. While B&S are dead-on with sooo many great engines, they dropped the ball BADLY with this one.The head gasket configuration is SO inadiquite, that a first year engineering student would know it was/is doomed to repeated failure. After 40 years of repairing engines in automative, power equipment and marine applications (all of them#, I think I've earned the right to vent on this engine's shortcoming#s), and there are several.The latest adventure was when a customer called in the spring with a "won't start" call. Back at the shop we discovered a mouse nest the size of a Buick under the cover (we do dozens of these every year). Other than that, the cooling fins were clear, so it should have been as easy as cleaning it, and replacing the coil that had its plug wire chewed in 2 by said mice.Installed the new coil and it wouldn't start. Threw a commpression tester on her and had 2 pounds. Bummer.Replaced head gasket only to discover valve guides and pushrods were worn beyond spec, so compression was still low. Even then, the starter was taxed badly to turn her over. I won't even TELL you how upset I was to discover the intake lobe of the cam was worn.A bad head gasket design leads to failure, which in turn sets in motion a series of failures cascading through the ENTIRE VALVE TRAIN.This is a disposable engine with a VERY short life span. SHAME ON YOU B&S.

Rated 2 out of 5 by from Earlier model has head gasket problem I hope that the improvements in the "XRD" system include a redesigned head gasket system. My 6 year old engine (31P777 series) has required a new head gasket twice so far. The gasket fails in the area between the cylinder wall and the oil galley, allowing exhaust to contaminate the oil and oil vapor to be drawn into the cylinder. The original gasket managed to hold up long enough to be out of the two year warranty. I noticed that the latest gasket has a new part number; hopefully it has been redesigned.I have found that older B&S engines seem to run forever with no repairs; my oldest (23 years) is in a push mower.

Rated 1 out of 5 by from ROTTEN!! I have owned this for just over 2 years, and it is burning oil!! Just out of warranty, that figures. I contacted Briggs about warranty, no answer. I will never get another Briggs engine in any power equipment...unless I plan to sell it after one year!!
