I'm new to posting threads, but have been reading a bunch of them. I have a serious question and really don't want personal opinions about my mower of choice. To each his own. My question is this, Has anyone had this similar problem and what corrected it? I have a 48" Great Dane Chariot ZTR that has stripped the pulley off the spindle shaft on two separate occasions. It is the spindle on the right, closest to the discharge chute. This is a 3 blade deck. It happened last year, then it happened 2 weeks ago. Each time I had to replace the shaft and the pulley ( about $105 each time ). My dealer has no solution. I check the pulley tightness every day when I change blades, and the belts are adjusted properly. The other 2 pulleys and shafts are fine. Any help with this is greatly appreciated.
