This can be due to a belt slipping or a bad spindle bearing.
And on the difficulty scale,10 being extremely difficult, The belt would be a 1 or 2 and the spindle about 6 or 7 (because the deck usually needs removed for this job)

Note: This is about a different mower, but it might be similar enough to yours. If not, please disregard. Thanks!
I had a similar issue with our mower, a 2006 Troy-Bilt Pony model 13AN77TG766 (17.5 HP, 42 inch deck): when I pushed the handle down to engage the blades, it took a good ten seconds or so to start the blades turning; even then, they didn't have enough power to cut the grass. And on any height setting lower than 5, they wouldn't turn at all.
The cause was on page 19 of the manual <URL:http://manuals.mtdproducts.com/mtd/DocGetter?doc=769-02243a.pdf>: Figure 17 shows the "PTO" cable attaching to a hole on the edge of the deck idler bracket, but it was shipped from the factory attached to a hole in the middle of the deck idler bracket, about 3 cm (1 in.) closer to the front end of the machine. I reattached the cable to the original hole, and the belt is now good and tight; the blades engage as soon as I push the handle down.
Now, today, I'm having problems with the belt popping off the right-hand idler (hopefully just needs the deck stabiliser rod adjusting).
Always remember to remove the spark plug wire before you go near the blades; and watch for hot, sharp, and/or pinching surfaces.

Try pulling on the cable coming down to deck. This cable might be your problem. Also check that the spring on the end of this cable is present and functional.

is the belt spinning & smoking when blades are engaged or the belt won't spin if the belt spins but blades wont go then there is something stuck under the deck or the bearings are gone out do to not being greased

maybe the safty switch under seat might be starting to go out if that switch doesn't work the blades wont come on at all for safety
