Grass is probably the most unpredictable surface there is to drive across. When it is dry it is usually a very good surface to drive over as it offers plenty of grip. However, when wet it can be treacherous to drive over due to the changing characteristics of the surface when wet. It can be as slippery as ice at times. Fresh grass can change very quickly when it has become wet from a surface offering lots of grip to that of a very slippery one. Treat grass much as you would do for mud. Drive it slowly and carefully in second or third gear to help minimise wheel spin. Use the steering, brakes and throttle with care at all times trying to avoid wheel spin. Grassy hills and inclines are best avoided when wet and slippery, as the possibility of sliding out of control is just too dangerous to risk.
Don’t drive too fast through long grass as it could be concealing hidden dangers, such as rocks, holes or tree stumps and if you hit an obstacle like this at speed there is a real danger of losing control or worse still, breaking something. Dry grass also contains lots of seeds and pollen, which will end up clogging up your radiator and intercooler. Clear them regularly to prevent overheating. Be careful when driving over tinder dry grass too. Hot exhausts can cause serious fires in dry grassland areas and if the only way out is the way you came in, the fire extinguishers may be working overtime!!
