Case IH Maxxum 135 Horsepower FAQ
How much horsepower does the Case IH Maxxum 135 have?
The listed engine output is 135 hp, above the 80 hp benchmark average. That is a higher-power result, so ballast, tire setup and implement width matter if you want to use the full 135 hp.
How much PTO horsepower does the Case IH Maxxum 135 have?
The listed PTO output is 110 hp, above the 65 hp benchmark average. That is the number to use for mowers, balers, augers, pumps and other PTO tools that need up to about 110 hp.
How much drawbar horsepower does the Case IH Maxxum 135 have?
The listed drawbar output is 86.8 hp, above the 55 hp benchmark average. That makes the 86.8 hp drawbar number more useful than engine hp for tillage and heavy pulling.
How much engine power reaches the PTO on the Case IH Maxxum 135?
The PTO-to-engine transfer works out to 81.5%, from 135 engine hp to 110 PTO hp. That is a normal usable range for judging PTO implement fit.
How efficient is the Case IH Maxxum 135 for pulling work?
The drawbar-to-engine transfer is about 64.3%, from 135 engine hp to 86.8 drawbar hp. That means traction losses and drivetrain losses are a big part of the real pulling result.
Is the Case IH Maxxum 135 better judged by PTO hp or drawbar hp?
The drawbar output is about 78.9% of PTO output, comparing 86.8 drawbar hp with 110 PTO hp. That helps separate pulling ability from PTO implement ability.
How big is the Case IH Maxxum 135 engine?
The engine displacement is 274 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 Maxxum 135 engine stressed for its PTO horsepower?
The engine has about 2.5 cubic inches per PTO hp, using 274 ci and 110 PTO hp. That is a smaller-displacement, higher-output style result.
How much PTO horsepower per liter does the Case IH Maxxum 135 make?
The output density is about 24.4 PTO hp per liter, using 110 PTO hp and 4.5 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.
