my husqvarna 460 rancher is vibrating like crazy in my hands, way more than it used to. what's broken?

Excessive vibration means the LowVib anti-vibration system is compromised. Check the mounting points.

1. Inspect the rubber vibration dampeners that isolate the engine/handle assembly from the saw body. Look for cracks, tears, or deterioration.
2. Check that all bolts connecting the handles and the engine housing are tight. A loose bolt can transfer vibration directly.
3. Ensure the chain is correctly tensioned and the bar nuts are tight. A loose chain or bar can cause imbalance.

IF THAT DIDN'T WORK: The clutch or flywheel could be unbalanced due to damage or debris buildup. The drive sprocket may also be worn unevenly. Internal engine issues like a failing bearing will also create severe vibration but are less common.

HEADS UP: Prolonged use with high vibration increases fatigue and risk of injury. Have the dampeners and internal components inspected by a technician if basic checks don't solve it.
