Norm,
I've gone out of my way to thank you previously for how generous you are with your assistance.
That said I'm unsure why you've posted to chastise me for stating that I'm getting frustrated with the 550 Pro's I have? You act like I am personally criticising yourself - which clearly wasn't the case and couldn't be further from reality.
With all due respect MY own maintenance on these mowers since I have them is top shelf - alas I've only had them for 12mths or so and used a scant number of times as I prefer to use my Honda - so the 'maintenance' issue resides with the owner from the previous ¬30yrs of their lives - not myself.
To say that I should know my way around them by now & have rectified the previous owners faults is a bit much as it's not like info for these is easy to ascertain etc - so with all due respect I don't believe such comments are either warranted or helpful. There's no user or workshop manual for them hence even to change a belt the most logical thing is to ask on ODK. I know you're very knowledgeable with these - alas not all of us are.
And to be fair I think you'll find that I said to you regarding the 24's that I didn't believe they'd be suitable as pushing such a mower across this terrain isn't viable....but I did tell you I'd keep a look out, which I have done. You will just have to take my word being that I've mown this property now for 5yrs, that a 24" push mower is not a good fit.
The belt issue is the only current issue I have with them - if you know the best way to attack this I'd be most appreciative. :-)
