Which should you choose?

We will not advise between these two machines, because their unladen weight differs by more than 25% (35%). The figures below are side by side so you can judge them yourself; each says whether it was measured, claimed or declared by its source.

Height is not in this table. It is not one measurement: the sources measure it to different points — over the cab on some machines, over the steering wheel or the exhaust on others — and the same tractor measured two ways can differ by most of a metre. It appears here only when both machines' figures carry the point they were measured to and it is the same point, which is not the case for these two. Each machine's own page prints its height as its source gives it.
