I am purchasing two of these mowers next week with 72" decks, wanted to know how do the flex forks hold up on that size of deck. Also wanted to know what has been going bad? belts, spindles, pully's, etc. Also fuel consumption with the fx1000 engines please any info will be greatly appreciated. I am also getting the bag vac system, so if any of you own that let me know too. Thank you.
