Hi Bob, thanks for your reply.Sorry I have been in Melbourne and the laptop crashed so haven't been able to get to the forum.
I don't have any pics at this stage but could take some next weekend when the deck is coming off to replace blades etc. I have plated the front skirt with some sheet metal but this is not strong enough to resist the bending effect of thick grass not to mention the tufted grasses. My biggest problem is the holes appearing in the top of the deck which are now getting dangerously close to the centre pully mount. If this trend continues the shaft holding this drive pully is going to let go and the unit will be useless. I have considered plating the underside of the deck where the shaft is mounted but as the aluminium is breaking up I guess this would merely cause a larger piece to break out. What is the condition of the deck you have in the main pully area?
Also what do you think the price of a metal deck fabrication would be?
As stated in my original post the rest of this unit seems to be pretty reliable and I would rather not buy a new unit as we may sell this patch of land and move to a suburban block and have no further need of a ride on.

Cheers

Bob W
