Case IH CX80 Horsepower FAQ
How much horsepower does the Case IH CX80 have?
The listed engine output is 84 hp, close to the 80 hp benchmark average. That puts the tractor in a normal working range for this benchmark group, with 84 hp as the main engine number.
How much PTO horsepower does the Case IH CX80 have?
The listed PTO output is 67 hp, close to the 65 hp benchmark average. Use 67 PTO hp as the practical implement-sizing number.
How much drawbar horsepower does the Case IH CX80 have?
The listed drawbar output is 59.3 hp, close to the 55 hp benchmark average. It gives a realistic pulling-power figure of about 59.3 hp.
How much engine power reaches the PTO on the Case IH CX80?
The PTO-to-engine transfer works out to 79.8%, from 84 engine hp to 67 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH CX80 for pulling work?
The drawbar-to-engine transfer is about 70.6%, from 84 engine hp to 59.3 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Case IH CX80 better judged by PTO hp or drawbar hp?
The drawbar output is about 88.5% of PTO output, comparing 59.3 drawbar hp with 67 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH CX80 engine?
The engine displacement is 243.5 ci, close to the 260 ci benchmark average. It is close to the normal engine-size range for this horsepower class.
Is the Case IH CX80 engine stressed for its PTO horsepower?
The engine has about 3.6 cubic inches per PTO hp, using 243.5 ci and 67 PTO hp. That is close to the normal benchmark for this category.
How much PTO horsepower per liter does the Case IH CX80 make?
The output density is about 16.8 PTO hp per liter, using 67 PTO hp and 4 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
Horsepower and engine specs can vary by year, market, engine option, fuel system, test standard and tractor configuration. Check the operator manual, spec plate, parts book and official caseih.com website before buying parts, sizing implements or making repair decisions.
