WE too have a chariot jr. Have idler arn bushings go bad. I am adding grease zerts to the idler ams . We are replacing the idler pullies as they are a little bent, making the deck belt shake. Replacing the hydro pump arms cuz the control linkage holes are wore oblong creating earatic movement to where you dont want to mow any lawn. The mower is 4 years old. As to getting parts, some are not to bad . Most of time 3 days , as to replacing the current parts above, it has been 8 working days. I called supplier, going to be 4 more days. Still like the mower. Love the cut & spread of clippings. Gr8 in fall clean-ups. Cover discharge shute & grind leaves to a powder . Very user friendly machine. When we replaced the hydro pumps, the cost was up there at $380.00 apiece and labor was around $400.00 each. But I change them myself now. Quite the savings.
