The 4-wheel drive tractors did the primary tillage which requires high horsepower to deep till the soil and secondary tillage which
involves very wide shallow seedbed preparation equipment.
The 2-wheel drive tractors were for crop care such as planting, spraying and cultivating for weeds, mowing and powering augers.
The Steiger on the left has a 360 horsepower Cummins engine and is attached to a 47.5 feet wide field cultivator which prepares

the right is attached to a disk and is a 310 hp Cummins.
BIG...BAD...and RED . In 1989 we added this International Harvestor (Steiger) 9180.
It was our first tractor with "triples".
It also had a Cummins engine with 375 horsepower and a powershift transmission.
