I have a Ferris IS 5000 with a 61 inch cutting deck, for the past 18 months the cutting deck has developed a problem in the fact that it does not spread the grass properly.
The mower actually cuts really well, but has developed this fault of not spreading the grass evenly, I really don't know what the problem is, one thought is that perhaps one pulley is slipping slightly, although if a pulley was slipping, I would have thought this would have shown in the quality of the cut, but the quality of the cut is excellent.
I have attached a photograph of the mower cutting and leaving the grass in clumps, rather than spreading equally, any help would be appreciated, thanking you.
