Re-powering SR-21S with a B&S 750EX

[jaciche]

Hi,

The original B&S 6.0 GTS quantum engine on my super recycler is losing compression and slowly burning more oil. I'm guessing the end is near for that engine. My plan was to buy a new 725EXi with a 25mm x 3 5/32" shaft for this mower when the original engine dies. I was planning on buying Toro blade driver p/n 114-2774 for use with the new engine.

I did buy an engine on Amazon, but I got a 750EX engine in the box instead. This has a 25mm x 2 3/4" shaft. According to Amazon's customer service, this is a non-returnable item, so I got a refund for this engine and I can do what I want with it. I'd like to try and make my free engine work on this mower, but I'd like the blade height to be at or close to the same height as the original engine setup.

Should I get a different blade driver to use with this engine? Is there one that would work better with this engine and Toro blade? Otherwise I'll make a spacer out of steel tube to put between the new shaft and my new blade driver.

Your free engine is partly responsible for driving up costs to everyone else. Do you think Amazon just eats the profit loss or passes on the cost to customers in the form of price increases?
