Hello Grumpy/Rodeobob,
Thanks for the encouragement amd sagely advice. I had to make 1 slight modification when I put everything back together, I had to take 3 inches of the end of the handle assy, where the heatshink was applied, so that the handbrake lever did not foul with the cutter engage lever, both levers work ok now, pall stays engaged in brake disc even when being pulled by my Pajero.
Rodeobob, the mower I have does not have a diff, it has a solid axle with the standard Greenfield disc drive system. If you need a pic of something specific let me know and I will get it for you.
Cheers Keith
