RT Series
RT - The RT is too noisy.
A noisy mower is typically because its blade is dull, bent or clogged with debris, accumulated mulched grass, vines, ropes, toys and whatever can get stuck at the wheels area and mowing deck.
Turn off the RT, remove its disabling device and put on heavy gloves before you raise the mower to inspect its mowing deck and blade. If clear, rotate the blade to see if it is wobbly/uncentered or damaged. Replace blade if needed.
If blade looks good, the mowing motor might be causing the noise: B__ring the mower t__o a servicing dealer.
If mowing motor is good, rotate each drive wheel then the rear wheel to see whether any of them is squeaky or noisy. If one of the wheels is generating the noise when rotated, clean anything wrapped around wheel or axle (dirt, debris, vines, ropes or toys).
If wheels are clean but one of them is making a noise when manually rotated: Contact Service Dealer
