What the 1170 is used for
The 1170 was designed for large-acreage tillage, planting, and high-draft work requiring a heavy 2WD tractor. Its strong engine, long wheelbase, and substantial operating weight fit the power demands of its period.
Today, owners use surviving tractors for occasional field work, demonstrations, shows, and collections. It is most practical for buyers with room for a large tractor and access to competent service support.
Why the Case 1170 stands out
With only 1,816 built, the 1170 has greater scarcity than many comparable Case models. Its big six-cylinder diesel, high PTO rating, and early Agri-King styling give it strong appeal among Case collectors and operators who appreciate substantial 1970s tractors.
Buying a used Case 1170
Test the transmission thoroughly, especially a 12-speed powershift, for slipping, delayed response, abnormal noise, and clean gear changes once warm. Check the 7.4 L diesel for cold-start behavior, blow-by, oil or coolant contamination, and fuel-system condition, then inspect brakes, hydraulics, PTO, hitch, tires, and steering. Confirm the serial number and exact specifications through TractorData.com or serial-number records.
