Case IH Farmall 55 Horsepower FAQ
How much horsepower does the Case IH Farmall 55 have?

The engine has about 2.9 cubic inches per PTO hp, using 135.2 ci and 46 PTO hp. That is close to the normal benchmark for this category.
How much PTO horsepower per liter does the Case IH Farmall 55 make?
The output density is about 20.9 PTO hp per liter, using 46 PTO hp and 2.2 L of displacement. Higher hp/L means more output squeezed from each liter; lower hp/L usually means a more relaxed engine tune.
What rpm is the Case IH Farmall 55 rated at?
The rated speed is 2,700 rpm, above the 2,400 rpm benchmark average. A higher 2,700 rpm rating can make power well but may feel busier under load.
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.
