in 4wd position: if you hear noise (transmission): this means that the front axle / rear axle ratio is modified due to the size of the tyres (this ratio can vary by around 6%)
solution: disengage the 4wd system.
(the purpose of lawn tyres is to drive smoothly, without any powerful traction effort) to avoid damaging the lawn: 4wd traction is therefore not recommended.
