I own an Exmark Laser HP with a 52" deck. By landscaping standards, this is lightly used. I mow my 4 acres and my parents 2 acres weekly (all flat unobstructed land - was a farm field 10 years ago). In 5 years of ownership, the mower now has 250 hours on it. I'm told the spindles are shot and need replaced. I'm a little surprised that a $ 700 repair (this was the estimate) would be needed with so few hours. I've reached under the deck and can find no 'play' in the spindle with the blade attached on 2 of them. One of them moves side-to-side slightly. Can someone tell me the best method to determine if a spindle is going bad or is bad and needs immediate replacement?
