I agree with Norm ,with Loctite you need to use an oxy to heat the bearing first to release the Loctite before you
hit the bearing out ,a LPG torch may also work.
The old Rover ride on mowers I guess aren't too difficult to find ,I thought they had the same wheels as the slasher,
usually I see them for $50. ,there was one not too long ago on Marketplace for $50.
I have seen Rover slashers for $50. but the ride on mowers come up more often for $50.
Cheers
