Rebirth of a 6 Foot Flail Mower
RobWilson:
Looking at the photos Andrew it looks like that mower has had absolutely no maintenance done on it since it left the dealers :bang:

I reckon it was driven by a maniac through a war zone - just my sort of re-build :bugeye:

Normal bearing shields are not very good on this one as you have seen. Grass/hay and other stuff has tendency to wrap around and attract debris, then shield is shot and next bearing. I have seen plastic fat shields, metal saucers, rubber grommets and in combination. Large discs close to bearing seem to work, but complicates structure. Not sure if gammaring is good?

awemawson:
Pekka, if you look at this picture you'll see the main flail shaft bearing is recessed into a shroud. The back roller bearing had an inner housing that probably had a simple seal, but as you can see in the second picture it is totally destoyed
PekkaNF:
That looks familiar. Forage harvesters had some accid feed in to preserve the grass and they lived hard life, even when they had a wash down of the innards. Only way to keep them operational was to pump grease trough the bearing after use to purge the debris out that was about to reach the seal.
I bet it has better life on your hands.
