Things you need to consider before purchasing any vertical shaft engine to ensure it fits your mower.

Bolt Pattern
Please check description for the schematic of the bolt pattern. If you have a Briggs & Stratton or Honda engine, the bolt pattern will be a perfect match. The bolt holes on the engine will require thread tapping.

Output Shaft Size
Output shaft on our engine is 1” (25.4mm). Most ride on mower engines with HP ratings between 10 to 18 hp have 1” shafts. But please make sure this is the same for your mower.

Engine Displacement
The displacement of the new engine shall not be less than your current engine to avoid any underpower issue.

Physical Size
If your mower has only limited space for the engine to fit into, you will need to check the physical dimensions of our engine carefully before purchasing. An illustration of the physical dimensions can be found in the images in the description.

Please note this is a universal fitment engine and some modifications to the engine or mower might be needed, including but not limit to the muffler, exhaust system and/or electrical wiring. If you are not familiar or confident to do so, please consult small engine mechanic before purchasing, installing and using.

Books arrived in fantasic shape.
Format: Paperback, Format: Paperback
I was worried about making the purchase due to other people having problems with miscut books and glued pages. I ordered the set of three and they are all in great shape. No miscuts or glued pages. Every page seems to be printed legibly. I'm very happy with my purchase. I didn't see any recent reviews so I thought this may help some of those hesitant to buy.

Good so far.
Format: Paperback
I will be using these heavily in a month or two, I ordered them because they were on sale so I will come back and edit once I actually read the material, use the glossary, online tools, etc. However from out of the box? All the books are in perfect condition, no sticking pages like other reviews. I will say if you can afford the hardcover version with the labs? Get those. From touching them once or twice so far, this book will not stand up to constant use. It's a really flimsy type.. not even sure if it's paper? It feels like plastic paper. I will also add that that study guide book is F A T . I wish they would have split it into two. I bet the hardcover is gigantic because mine looks like the biggest dictionary you've seen, and I know the cover page which is almost exactly like the pages? Will be ruined once it starts being used consistently.

Very Useful
Format: Paperback
I used these for my A+ exams and I didn’t really end up reading the material. I more so used them for their practice exams. That’s only because there’s a lot of information to digest and I was in a rush to take the exams. I still passed so I find that they are well formatted. The questions imo needs to be read more throughly than the exam questions themselves.
