RAY: not sure if you mower is same as others, it is best to take parts to a mower place to match stuff up, MY unit is a 5' imported by me back in 2001 it has many of the same parts as a BIG BEE brand mower. which it has a left hand CCW rotational direction. discharges out the left side of the mower. it has single long V belt from pulley to pulley to pulley, center gearbox drives drives the belt. it has one slack take up pulley as well. It is spring loaded. though I haven't had it off in a LONG while so I may not be remembering it well.
