After 12hrs use, I noticed someone, probably at the Exmark factory, drew a smiley face where the dipstick inserts into the block, 28hp Kawasaki.. I wonder? I think that someone knew I'd be happy with their product, 28hp Kawasaki, Exmark mower. I got a smiley face myself after seeing that....the dealer swears they didn't do it. Kinda sums it up for me....a new mower, a big smile on my face. No regrets. kenny.
