Thanks BB,
I took the mower complete to a local mower service centre where the cylinder was repaired (straightened and 'cracked flutes' welded), sharpened, cylinder bearings replaced, new cutter adjuster screws fitted and roller levels adjusted.
I am cutting back and forth east - west but have only been over the lawn the once. The thatch is thickest where the cuts are the most uneven whereas closer to the road where the thatch is shallow the cut is quite even.
It has been suggested elsewhere that this is primarily a thatch issue and that I should go over the current cut north - south to remove excess thatch.
Cheers, Sven
