Hi I am a believer in sharpening the blades. Just this week, I had the
blades on my 1988 MTD rider
(wow, what a coincidence) sharpened for the first time since I received
it.(yes, I AM cheap) and WOW, what a difference.

I mowed the grass in half the time as before. It does bog in high grass but
not nearly as bad as before

So I have had it for 4-5 years and yes, I SHOULD have sharpened them way
before.

As another reference point, the bogging down will cause the mower belt to
slip more and wear out quicker

I have 1988 mtd riding lawn mower that bogs down when into thick grass.
This time of year it is about 75% thick grass. It has a BS 12HP engine on
it and I have tuned the carb properly. Is it a rebuild probably? Or can
something else be tried?
