All finished. Assembled and tested out.
Everything works ok but I do notice a good but of vibration between 1600 and 1800 tractor RPM. No issues at Idle or at 540PTO which on my tractor is ~2500RPM. Just that one area while bringing up to speed.
Those of you with flail mowers, any ideas:confused2:
You have a dangerous imbalance some where;
Are all the knive pairs intact on the rotor with 2 grass slicers per hanger?
EDIT: Why is the Yoke so far away from the gearbox????????????, thats not good.
EDIT: your drive shaft does not look healthy after taking a second look with the photo enlarged.
I would take a good straight edge and palce it between the left and right arms of the flailmower
mount and spin the PTO shaft by hand.
The vibration may cease if you reposition the mounts on the furthest holes if not there already.
Candidly looking at the photo from from the right sideI think the drive line and yokes are suspect.
Are the yokes at 180 degrees to each other?, they must oppose each other.
This is sometimes usually the culprit as it should be balanced to the 2500 R.P.M.
Is the V belt tight? no more than a 1/16-1/8 of an inch of slack on the top belt?
Are ALL the grass slicer knives in place?
Are ALL the broken grass slicers removed with the corresponding opposite grass slicers removed?
Are all the broken knive hangers removed with the corresponding knive hanger rings and bolts removed?
