Lawnmowers are items that are often loaded last, partly because they are difficult to fit in, and partly because they need to be used just prior to departure to check out of housing. If you anticipate this, try to reserve a spot for them to help your load end neatly.
Most pushmowers have folding handles. Typically it involves loosening a couple of handles or bolts, then squeezing the handle together at the joint to allow it to fold. Ensure you don't crimp any control cables when folding the handle.Run the mower dry and drain the oil prior to loading to comply with shipping regulations and avoid having gasoline leak all over your goods. In addition to greatly increasing the risk of fire, gasoline can remove paint and finishes from furniture. To help avoid damaging the wheels, lower the mower to the lowest height setting.
