It's 100 years since the distinctive all purpose Farmall tractor (pron: farm-all) was introduced on a Texas farm aimed at replacing horses between the rows and reducing the need for a hired hand on small family farms.
A collection of vintage Farmalls was on display last month at the Central Districts Field Days.
The first grunting, puffing, chunky pieces of metal evolved into a very popular brand exported around the world including New Zealand.
The distinctive, mostly red tractors, became a fairly common site cultivating fields. The earliest models - built by the International Harvester company - had three metal rims for wheels.
