Well, here's something I knew nothing about until I started working on a recent project for a client...pushback tractors. Those powerful pieces of plant that move aircraft around the airport are in fact pushback tractors.
Apparently, there are two types: conventional and TBL (towbarless). PlantGSE sell both new and reconditioned plant vehicles such as aircraft pushback tractors and are widely considered to be a fast and flexible supplier. If anybody has any experience of driving one of these vehicles, that would be interesting!
