Customer Reviews

Rated 4.6 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Briggs 850 Good experience with order and pick up. Pricing is competitive. Engine has good torque and easy starting. September 15, 2016
Rated 5.0 out of 5.0 by Easy Purchase and Install Easy Purchase and Installation. I would recommend shopping from home anyday. August 14, 2016
Rated 5.0 out of 5.0 by 850 pro engine Excellent starts first pull plenty of power and torque. August 16, 2016
Rated 5.0 out of 5.0 by No Durability To the guy that Briggs wouldn't warranty his engine because the warranty expired. I work for a Power Equipment manufacture. Not Briggs And Stratton. I understand your disappointment at not being offered Good Will assistance but Briggs fulfilled their obligation to the full term of the warranty. Manufactures cannot help with warranty on every request on units beyond the warranty period. It's not like there's huge margins on equipment and a company can give away a replacement for each unit sold. Each situation is different and needs to be judged independently. There obviously was no compelling reason in your particular case. By the way I have this engine and it's awesome. May 23, 2015
Rated 5.0 out of 5.0 by A Real Bang for the Buck The 850 (5 hp) B&S is a smoking hot engine that gets the job done! When cutting grass, is seems like an easy task and not a chore when the 850 is running. It helps me with my walking exercise when I want to go at a faster pace while still getting the grass cut in a nice uniform manner. Everyone should try the 850 before buying another manufacturer's product. August 9, 2012
Rated 5.0 out of 5.0 by Great Powerplant I purchased this engine to refurbish a John Deere JS63 walk behind I found through an on-line search. It starts first pull everytime and cuts through thick grass easily. I like the Easy Start feature eliminating the need for a primer bulb and the fact that my wife can easily pull the starter cord without feeling intimidated. April 27, 2012
Rated 1.0 out of 5.0 by No durability I bought this engine from an authorized Briggs dealer in 2010. First engine came with a cracked block and I had to fight tooth and nail to get it replaced. After two months of battle I finally got a replacement, more due to the excellent folks where I bought it and not on Briggs end. For two years this "Pro" grade engine worked great, started on first pull, plenty of guts and fairly quiet. One month after the warranty ended it's all done. It just stopped running while I was mowing. It did not seize, had plenty of gas, oil was clean and a good filter. Brought it to my repair shop and they said the cam came off the shaft and sheared the oil pump off inside the engine. Briggs response, "Warranty is over". My repair guy plead the case that the rest of the engine was spotless inside and he could not find a reason for the issue, especially not on my end. Briggs response, "Calendar date" meaning once again that I was out of warranty and they would offer no help. So now after 25 years I am no longer a Briggs customer, I will be looking to Honda which is a shame because I believe in buying Amercian Made, but not Briggs....P.S. This was used once a week as a homeowner. September 16, 2012
Rated 5.0 out of 5.0 by easy start like this engine. time of ownership will tell on value. The oil pressure on a grade not a standard option will not effect me . August 9, 2012
