Best Deal Around,
September 25, 2009
By joehorse
from Gautier, MS
"I read the reviews with Northern Tool, and some Competitors, but Northern was the better overall deal. Others had a lower price with free shipping BUT...........
NO MUFFLER ......which would have meant another order and more money. Engine arrived (UPS) around 2:15 PM and it was mounted and running at 5:00 PM. I did have to tapp two mounting holes on the base (mounting plate for Snapper) but that wasn't any big deal. I did NOT experience the damaged shipping carton that others have mentioned. (maybe B&S have improved the shipping carton) This replaced a 15 HP on a 3 1/2 year old Snapper and seems to be an okay engine, better balance for a smoother operation. (the previous one wasn't) I AM USING THE MOBILE ONE OIL, especially since the last one had such a short life. It would be really nice if this one would last longer than the Mower. I certainly recommend Northern Tool for replacement Briggs and Stratton Engines. Excellent service, Northern Tool !"

It couldn't be easier,
July 13, 2009
By Jimcanfixit
from Newburgh, NY
"Right out of the box I installed the engine, filled the crank case oil and gas tank and it started first pull. It couldn't have been easier. I priced around for this engine and the next best price was $120 more for the same thing. The shipping was fast and the engine runs great. I have been using it for a few months now and it still starts first pull."

Perfect fit,
April 10, 2009
By MoonlightHacker
from Altoona, Pa
"I ordered the product on a Friday and received it on the following Tuesday. The condition of the package was perfect, I know a few of the reviews commented on the poor condition of the packaging but, I didn’t have this problem. The product was just as described. The engine fit perfectly in my Craftsman DYT 4000. The only thing I had to modify was a few electrical wires and install the old muffler. Total time to switch out the engine took about 3 hours."

"This was an excellent replacement engine for my Craftman 42 inch mower. I got 7 years of service from the orginal Briggs & Stratton engine and hope to repete that with this new one. It was easy to change out and is working great. The price was also great."

John Deere 111,
November 17, 2008
By Joe1234
from Kansas City
"This Briggs & Stratton Vertical OHV Engine with Electric Start was the best purchased for my John Deere lawn mower. It has plenty of power and it's very reliable. I had to make a few modifications to my application. But in all this is a great product for the price. I have looked at many competitors but the price of the engine was higher than Northern Tool. I honestly feel that I got a great product at a great price. The delivery was very quick."

Great Product!,
January 23, 2008
By lee361
from Casco, WI
"I purchased this engine to replace the 17.5 hp tecumseh that came on my 46" Murray lawnmower. Delivery was fast and engine install was easy except for the wiring which required removal and use of a diode off the Tecumseh engine wiring harness.
The engine starts easy and runs quiet. I was amazed to find a quality engine at such a reasonable price. Thanks!"

17 HP Vert shaft B&S engine,
October 29, 2007
By Hazmat
from S.E. Iowa
"For the money, you probably can't find a better replacement engine in the 12-18 HP class.
I got this for my 60" trail mower to replace the (somewhat underpowered) original 12 HP. Plenty of power, now, and it seems to use far less fuel the the original doing much more work.
The only drawback was that I had to think long and hard about how to wire up the new motor, as it came with the anti-backfire solenoid at the carb...which needs constant power during operation to allow fuel to flow. In addition, the connection to the charging system had a completely different style connector.
For the charging system, you can purchase the proper style connector to replace existing ones, but I don't believe these connectors are available for the solenoid...even though a local B&S vendor swore they should have come with the engine. Parts are not available, so I had to cut off existing/new connectors and replace with standard bullet style.
Not that big of a deal, as I'm very familiar with wiring requirements. Someone not as familiar would have struggled with this quite a bit.
Other than that, it's a clean, quite running, very fuel efficient engine for the money."

broken mower,
October 8, 2007
By HAPPYTRAILER
from STL MO
"i needed a new engine for an old craftsman 10 horse mower. found this one, in catalog, was less expensive than a 10 horse replacemt. figured was worth a try. bolted right in place. simple easy wiring hook up. took less than an hour to install. engine has more than enough power for my uses. minimal vibration, easy install and startup. only drawback engine was bigger than original had to modify orignal cowl (cover) not a big deal thats what tin snips are for."

Back in the saddle again,
July 27, 2007
By craggy
from Orlando, FL
"I wasn't sure which 17HP engine to order (2 diff listed) until I read a well timed review in which they described replacing an engine on the same 1742 Scotts mower as mine. That review sold me. Thanks. Ordered on Sat and received on Thursday. Installation was easy. Had to transfer old muffler, dipstick housing assy, oil drain tube extension. Had to cut & splice two wires in order to use original electrical connector plug. Also, new engine came without tapped mounting holes in block. Used bolts, lockwashers, & nuts to mount to chassis. Ran great first time out. Purred like a kitten. Was pleasently suprised to see that this was an I/C (Industrial/Commercial) engine. Hope it lasts longer than the original (died with only 300 hrs on it). Thanks again, was a real pleasure doing business. I especially liked the money I saved which was about $1000 from quotes from gong through local John Deere or Authorized Briggs & Stratton Dealer."

Cheap and Easy,
July 4, 2007
By Nomad66
from Texas
"Used this engine to replace a worn out 17hp Briggs & Stratton Intek on a
Scott's 1742 mower. Ordered it on Monday morning. It arrived on Friday
afternoon. Engine came as pictured, completely assembled with a new
alternator/voltage regulator, starter and carburator.
After installation (and minor adaptation) it started right up and ran
fine. It is an easy change if you have all the tools and a good back.
One man job completed with hand tools inside of 3 hours. For the price
of a couple of repairs, I have a new engine as well as a box of spare
parts for my own repairs.
Be sure to compare the old and new engines before starting the work. I
had to remove the muffler from the new engine and reuse the existing
exhaust system. I was also forced to move the dipstick tube/crankcase
port over from the old engine since the new engine came without a
take-off port. Adaptation added less than 30 minutes to the job."
