Hi, we bought a Robomow 630 from you recently. I installed it last Saturday and initially it was very quiet. However after a few days it started to sound very loud, and now sounds like a bit of a tractor after less than a week. I had a look at the underside to see if anythign was stuck, and it doesn’t look like it is. Do you have any ideas what can be causing all the noise?
Thanks, Sam
