Case IH MXM190 Maxxum Horsepower FAQ
How much horsepower does the Case IH MXM190 Maxxum have?
The listed engine output is 190 hp, close to the 210 hp benchmark average. That puts the tractor in a normal working range for this benchmark group, with 190 hp as the main engine number.
How much PTO horsepower does the Case IH MXM190 Maxxum have?
The listed PTO output is 160 hp, close to the 175 hp benchmark average. Use 160 PTO hp as the practical implement-sizing number.
How much drawbar horsepower does the Case IH MXM190 Maxxum have?
The listed drawbar output is 137.6 hp, close to the 150 hp benchmark average. It gives a realistic pulling-power figure of about 137.6 hp.
How much engine power reaches the PTO on the Case IH MXM190 Maxxum?
The PTO-to-engine transfer works out to 84.2%, from 190 engine hp to 160 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH MXM190 Maxxum for pulling work?
The drawbar-to-engine transfer is about 72.4%, from 190 engine hp to 137.6 drawbar hp. That gives a more grounded pulling estimate than engine horsepower alone.
Is the Case IH MXM190 Maxxum better judged by PTO hp or drawbar hp?
The drawbar output is about 86% of PTO output, comparing 137.6 drawbar hp with 160 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH MXM190 Maxxum engine?
The engine displacement is 456 ci, below the 520 ci benchmark average. Smaller displacement usually means less engine size behind each horsepower number.
Is the Case IH MXM190 Maxxum engine stressed for its PTO horsepower?
The engine has about 2.9 cubic inches per PTO hp, using 456 ci and 160 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Case IH MXM190 Maxxum make?
The output density is about 21.3 PTO hp per liter, using 160 PTO hp and 7.5 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.
