- New Holland WM25 with 200LC front end loader, filled R4 tires 43X16.00-20 and 25X8.50-14 (had a Kubota B6200D with dozer and R1 tires)
Browsing the product line sold at my friendly nearby dealer, I notice that different models are in subgroups of about three that are exactly the same in every specification except horsepower. For example there are 92, 100 and 112 horsepower versions, whose weights and dimensions and engine displacements and RPMs and transmission options and hydraulic capacities and... well, every number in the table of specifications, are exactly the same. Then there might also be fairly similar 80, 72 and 65 horsepower versions that are smaller and lighter and have other specifications that are generally lesser, but those three will also be identical to each other.
How do they do this? What are they actually changing? Are they grinding the camshafts differently? Some engine control electronic settings that are fiddled with?
Are the most powerful horsepower models in each of these subranges less reliable because they stress all the same components more?
Are the least powerful horsepower models in each of these subranges hobbled in some way?
