Hi 2011PabloEscobar, and a warm welcome to the forum. It's nice to have you aboard. grin
Thankyou for posting that link, I have read it before and found it a very interesting article, however matching the FOC to your lawn with that degree of accuracy would be sometimes almost impossible because some machines only give you the choice of the cylinder reel they are fitted with at manufacture.
Scott Bonnar however, have a 6 blade reel for the 17" Model 45....and an 8 blade reel for the 20" model 45 as standard, but you can get a 10 blade reel for the 17" which is an 'after market' purchase.
To get a good result, Scott Bonnar must have averaged out the FOC with the height of the 'average' lawn.
cheers2
