hi there what a great site fantastic ive had my 430 for about 8 years now.can someone please tell me the diffrence between the 430 and the 590 models.and there always seem to be alot of mower shops out there that dont like working on the diplomats,what is the reason for this, and also are parts still avalaible for this model as my mower shop stated these mowers are no good,and if my clutch goes its time to get a new mower is this correct?as i have never had a proplem with my diplomat.i love the idea of the rear catcher i can get into tight spots.hope someone can help answer my questions.love my diplomat .also is there any way of getting a copy of the manual for this model cheers marc from adelaide
