## Description

CARB Non-compliant - can't ship to California

Review: Great engine. - This engine has been an absolute work horse for me. I mounted it on a swisher trail mower and I put it through its paces over the last couple of mowing seasons. It has yet to let me down. Worth every penny. I had to alter the pull behind mower a bit for the new engine but once that was done it bolted right up and fired up pretty much instantly. If needing a new mower engine you can’t go wrong.
Review: Check the size of the verticle drive shaft you need and have a little help lifting onto the frame. - I purchased this one year ago and use it a few times a week for our stable animal clean ups and cutting grass. The installation went in fine with a little help from my Grandson to lift it onto the frame of my GD LA120 which I have had for 17. I recently replaced all the wheels, tires, belts, blades and steering mechanism, so I decided to go for this upgrade instead of buying a new tractor. My original BS 21hp gave me 860 hours of life before freezing up and giving up the ghost. I was very careful in ordering as I wanted to make sure I had the correct shaft size and everything would fit. The fuel line needed to be extended, other than that I don't recall having an issue with the installation. I have about 40 hours on it in AZ dry heat so very happy since it saved me about $2k if I bought new.

### ⭐⭐⭐⭐⭐ Excellent Replacement Motor
*by A***R on July 14, 2024*

The New 25 HP Briggs and Stratton engine was a great replacement for my tired old 22 HP Briggs and Stratton motor. The new engine fired right up and has lots of power. Really nice to have it not bog down when the mower deck is engaged. It saved me from replacing my entire mower at this time and will likely get us another 3 or 4 seasons out of our old John Deere lawn tractor. That would make it about 20 years old upon retirement. Not bad for a ‘box store’ mower.
