Case IH CX70 Horsepower FAQ
How much horsepower does the Case IH CX70 have?
The listed engine output is 73 hp, close to the 80 hp benchmark average. That puts the tractor in a normal working range for this benchmark group, with 73 hp as the main engine number.
How much PTO horsepower does the Case IH CX70 have?
The listed PTO output is 58 hp, close to the 65 hp benchmark average. Use 58 PTO hp as the practical implement-sizing number.
How much drawbar horsepower does the Case IH CX70 have?
The listed drawbar output is 50.2 hp, close to the 55 hp benchmark average. It gives a realistic pulling-power figure of about 50.2 hp.
How much engine power reaches the PTO on the Case IH CX70?
The PTO-to-engine transfer works out to 79.5%, from 73 engine hp to 58 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH CX70 for pulling work?
The drawbar-to-engine transfer is about 68.8%, from 73 engine hp to 50.2 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Case IH CX70 better judged by PTO hp or drawbar hp?
The drawbar output is about 86.6% of PTO output, comparing 50.2 drawbar hp with 58 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH CX70 engine?
The engine displacement is 258 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 CX70 engine stressed for its PTO horsepower?
The engine has about 4.5 cubic inches per PTO hp, using 258 ci and 58 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the Case IH CX70 make?
The output density is about 13.8 PTO hp per liter, using 58 PTO hp and 4.2 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
Official information note
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.
