The fan & the pulley are bolted together
that assembly sits on the input shaft
What you are trying to ss is if the the pulley is in fact turning the shaft on a 1:1 ratio
There are lots of ways to do it and the exact method I use depends upon how much space my fat fingers have to work in
So some times I put a white dot on the pulley & the shaft that align
rub=n the tranny for a couple of minutes under high load ( low engine revs full pedal in both F & R ) then check the dots still align
Some times I can get a pair of pliers on the shaft under the pulley and while holding the shaft try to turn the pulley
Some times I just put my finger on top of the shaft and feel for the shaft turning in sync with the fan
Your symptions would usually be 1 of the following which for me are roughly in this order
1) belt failure ( includes clutch idlers & springs )
2) pulley stripped on the input shaft
3) wear in the hydro controls ( includes debris build up around the transmission )
4) worn out transmission
The other 2 are loss of hydro fluid which is usually evident and owners omitting to replace the drive key in the rear axels ( all except MTD )
