Case IH Puma 145 Horsepower FAQ
How much horsepower does the Case IH Puma 145 have?
The listed engine output is 146 hp, below the 210 hp benchmark average. That is a lower-power result, so the smarter match is lighter implements and jobs that do not demand more than about 146 hp.
How much PTO horsepower does the Case IH Puma 145 have?
The listed PTO output is 120 hp, below the 175 hp benchmark average. For real use, size PTO implements below or near 120 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the Case IH Puma 145 have?
The listed drawbar output is 113.9 hp, below the 150 hp benchmark average. For pulling work, the safer assumption is about 113.9 hp at the drawbar before soil, ballast and tire limits are considered.
How much engine power reaches the PTO on the Case IH Puma 145?
The PTO-to-engine transfer works out to 82.2%, from 146 engine hp to 120 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH Puma 145 for pulling work?
The drawbar-to-engine transfer is about 78%, from 146 engine hp to 113.9 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Case IH Puma 145 better judged by PTO hp or drawbar hp?
The drawbar output is about 94.9% of PTO output, comparing 113.9 drawbar hp with 120 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH Puma 145 engine?
The engine displacement is 410.6 ci, below the 520 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the Case IH Puma 145 engine stressed for its PTO horsepower?
The engine has about 3.4 cubic inches per PTO hp, using 410.6 ci and 120 PTO hp. That is close to the normal benchmark for this category.
How much PTO horsepower per liter does the Case IH Puma 145 make?
The output density is about 17.9 PTO hp per liter, using 120 PTO hp and 6.7 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.
