Hi everyone, having restored my Hayter 21 she is now in regular service mowing the normally very long grass around the lakes of a fishing club I help run. So to keep it in full working order I thought i would get keen and service the gearbox, it has no paint left on so im unsure as to which one is fitted but it looks to me like its the serviceable one. So my question is any idea on what oil to refill it with?? EP90 would be my first guess but the old oil does not have that lovely and unmissable EP90 smell ha ha ha. Im also thinking EP90 might be a bit thick when its cold, I did wonder if something like AQF auto transmistion fluid might be better? any ideas guys???
