On our farm, we have a variety of trailers for the tractors to pull. Some of them will be able to carry livestock whilst others are used for muck spreading or for moving loads of hay or straw around. It does not matter what sort of trailer it is, we need to make sure that the wheel bearings are properly greased up so that they run smoothly. Sometimes a trailer will not be used for up to 6 weeks during which time the wheels could stick and become difficult to move when we do need to move them. It does not take long to do but is one of those fiddly jobs that the lads would like to put off.
