Case IH Maxxum 125 Horsepower FAQ
How much horsepower does the Case IH Maxxum 125 have?
The listed engine output is 125 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 125 hp.
How much PTO horsepower does the Case IH Maxxum 125 have?
The listed PTO output is 105 hp, below the 175 hp benchmark average. For real use, size PTO implements below or near 105 hp rather than using a bigger engine-horsepower number.
How much drawbar horsepower does the Case IH Maxxum 125 have?
The listed drawbar output is 90.9 hp, below the 150 hp benchmark average. For pulling work, the safer assumption is about 90.9 hp at the drawbar before soil, ballast and tire limits are considered.
How much engine power reaches the PTO on the Case IH Maxxum 125?
The PTO-to-engine transfer works out to 84%, from 125 engine hp to 105 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH Maxxum 125 for pulling work?
The drawbar-to-engine transfer is about 72.7%, from 125 engine hp to 90.9 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Case IH Maxxum 125 better judged by PTO hp or drawbar hp?
The drawbar output is about 86.6% of PTO output, comparing 90.9 drawbar hp with 105 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH Maxxum 125 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 Maxxum 125 engine stressed for its PTO horsepower?
The engine has about 3.9 cubic inches per PTO hp, using 410.6 ci and 105 PTO hp. That points to a larger-displacement, lower-stress style setup.
How much PTO horsepower per liter does the Case IH Maxxum 125 make?
The output density is about 15.7 PTO hp per liter, using 105 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.
