What does the scale reference mean? It represents a size of the model in proportion to the real machine on which it is based. Eg: 1/16 scale means it is one sixteenth the size of the real machine; while 1/64 scale means it is 1/64 the size of the real machine.
For a modern 2WD or FWA tractor:
1/16 scale model is typically about 30 cm long.
1/32 scale is typically about 15 cm long.
1/64 scale is typically about 7.5 cm long.
4WD articulated tractors are somewhat larger and small tractors like the grey Fergy are somewhat smaller for the same scale.
Eg: 1/16 scale 4WD articulated tractor = about 45 cm long.
1/16 scale grey Fergy = about 16 cm long.
There are many other scales for the models, particularly earthmoving equipment and trucks which are typically 1/50 scale, and as the real machines of such models are quite large, a 1/50 scale model of such machines could be in the range of 20 to 40 cm long.
Scales relative to Model train gauges:
1/87 scale is equivalent to HO gauge
1/64 scale is equivalent to S gauge
1/43 and 1/50 scale is approximately equivalent to O gauge (1/48 scale)
