Tradesman engines are the perfect to power the equipment you use to maintain your home and yard, like a garden tiller, log splitter, pressure washer, water pump or portable generator. Count on our versatile and durable utility engines to perform consistently and start easily, no matter how tough the job.

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.

Good Sized Treat for a 35 llbs dog, smaller it will interfere with daily meals.
Flavor Name: Chicken Chips, Size: 1 Pound (Pack of 1)
The texture is hard as a chew treat, my two small dogs can smell the container being opened and tapping my leg to give it all to only one. Size is one chicken piece rolled tightly, so i have to cut it up completely and share it between my 15 yr old MinPin and my 2 yr old miniature shepherd mix. This will be used only every other day so it will take about a month or more to us first of two bags. The cost also drew my eye and the fact that just two ingredients which should not affect the health of my MinPin.
