Due to the weather conditions, many golf clubs are not allowing electric trolleys on the course, unless they are fitted with winter wheels or hedgehogs. Obviously you have to comply with this ruling.
However, it is wortwhile to bear in mind that these wheels often put adittional strain on the motor, battey and gearbox and may cause premature wear.
Although it's not a definite cure, keep you bag as light as possible and try to keep out of long wet grass and thick mud as much as possible.
