My son said he noticed a vibration in his 2002 Scag Turf Tiger 60". As he drove away I noticed the left rear wheel was wobbling. Found that all the lug nuts were loose and had ruined the wheel holes. We faithfully check all nuts and bolts, including lugs, every 100 hours. As the machine was only 1 year and 4 months old took it to dealer who replaced the wheel and said he would turn the bill into Scag for Warranty payment. Got the bill this past week for $226.72 from dealer stating "Submitted warranty to Scag but did not pay due out of warranty by 5 months". Was under the impression the warranty was for 2 years. Contacted Scag but have heard nothing yet. Has anyone else had the problem with either of their drive wheels on a Scag? Will let you know how Scag responds to my warranty question. Don Montross, Sr.
