Briggs & StrattonVertical Engine 19 HP 540cc 1''x3-5/32'' #33S877-0043, Black

The EX1900 is a great engine. Just add oil and you’re ready to rock and roll. Engine isn't really loud like my old engine. Only thing is the middle points to the side instead of the bottom. Great quality. Great price. Highly recommend!

Easy setup. Shipping was fantastic. The engine mounting holes are not tapped so be prepared if you're doing this install for the first time.

The product was a perfect fit for my Ariens riding lawn mower and was delivered three days earlier than stated. You do have to thread the four mounding holes unless you have self threading bolts but that was stated clearly in the item description.

Great engine, works better then the original.

Best idea I had to install a new engine on that riding.mower

Used this engine to replace the B&S Intek 20 on a Craftsman garden tractor (ca. 2008). I noticed the mounting bolt holes were smooth and needed to be threaded so I used self-threading bolts. Everything on the engine connected to the tractor control cable and electrical harness with little problem.Bibbidi Bobbidi Boo - we are back in business! BE SURE TO ADD OIL BEFORE STARTING and perform an engine jog (run with starter without spark). This engine is smooth-running and strong.Fair warning regarding our application: the engine comes complete with EVERYTHING (starter, muffler, carburetor, oil filter). The muffler included with this engine interferes with the garden tractor's hood frame (hood cannot close with it in place). The tractor is being run without the hood for now (grass is already too high) but will pursue removing this muffler and attaching the old one; it has an exhaust manifold pipe that is directed toward the lower part of the tractor frame. An alternative would be to cut the frame or stretch it around the attached muffler but the lower mounting of the original muffler is preferred.

Purchased this to replace a blown motor in a 2006 JD 115. Fit perfectly in place of the blown motor. It did take awhile to get the mounting bolts to bite into the aluminum and tighten up. The rest was very fast. Its not cheap, but way cheaper than buying a brand new low end JD mower that are going for around $2.5K.

Purchased this for our mower when the original motor broke. Husband installed it without delay or problems and I was back in business to mow our yard. Saved a bundle over taking it to a mower repair shop.
