Briggs & StrattonBriggs & Stratton Intek Series, 19 HP, 540 cc, Single Cylinder Engine

I replaced a Kohler Courage 18 in a Toro LX420 with this engine. It was almost a direct replacement (same engine shaft, attachment pattern, and wire harness). The attachment holes had to be tapped. The exhaust is on the side, rather than the front for the engine that I replaced. I did have to modify a bracket for the cover on the tractor, as the engine exhaust caused a slight interference. But other than that the Briggs installed without a problem. It started on the first try and runs great! I have about 2 hours on it with no problems.

Perfect replacement for a Briggs & Stratton 31P777 18.5hp engine. Completely plug and play. No modifications needed. People complain that the holes aren't threads for the holes that bolt the engine to the frame. The bolts that hold the original engine are threar cutting bolts. They will cut threads as they are run in with an impact. Took me 15 minutes to swap the engines out and have it up an running.

Great product fast shipping works great

The media could not be loaded. Blew up my zero turn (Toro time cutter z5000), purchased this as its replacement. It functions well, has great power, all the wiring was plug and play which made the swap effortless.

Perfect fit for my craftsman lawn tractor. Very easy to swap out the bad engine for this new one. Runs awesome. It's been 6 months and engine performing flawlessly.

The media could not be loaded. I don’t do many reviews on products, but in this case I will. Because this information may be very useful to someone else that had the same problem or concerns.My 42” inch cut Husqvarna model YTH18524 engine shattered the piston arm cause of the balancer broke and it made the piston rod just explode. The motor was the 18.5HP 33R777-0005-G1 and I was looking for replacing just the parts. But it was a catastrophic failure in the motor. So I was on a hunt for a new motor… come to find out, the 33R777-0005-G1 are discontinued. So now I was upset cause now, I need to find a new Mower now versus a new motor… I was upset to say the least. But I started doing a lot of research on replacing the motor still. From the marketplace, eBay to amazon. Wasn’t sure buying a used motor on marketplace or eBay would been the best idea.. So got on amazon and seen the 19HP 33S877- 0019-G1 Motor. I researched into this motor extensively to make sure all components are compatible with my Husqvarna YTH18524. To my surprise, it was compatible with my mower. So I ordered it.I came fast, earlier than expected. Packaged well. Took the old motor out and dropped the new one in. Note the 19HP 33S877-0019-G1 “DOESN'T HAVE THREAD FOR EXISTING BOLTS” you can either use a threader and cut your own threads or you can get bolts and just bolt it on. The motor mount holes lined up perfectly and bolted on with ease. The electric harness was an exact match so all I had to do was plug and play, and connect the starter wire. Now with my mower it’s not a side exhaust, it’s a front exhaust and I ordered the 532137352 Muffler Kit (Muffler & 692236 Gasket) for Husqvarna and took off the side muffler that comes with the motor and switched with the front muffler and it fits perfectly.Pleased with how easy it was to install and pleased with how it runs. Be sure to add oil to it before starting it. The motors don’t come with the oil in it. So be sure to add oil before starting. As for value. It was well worth buy the motor and replacing that instead of buying a new lawnmower. And the power of the lawnmower was exactly the same as the old motor I took out. Hope this helps someone else out there.

Great fit, plug and play. I decided to drill out the mounting bolt holes to use bolts and nuts instead of what my old Kohler courage engine used. Started right up, great power for my Craftsman tractor.

Perfect fit for my mower. Install was easy and worked amazingly.
