Barry and Yoder hit on some great points.
Be very careful rating working ability on hp
Barry runs a big mower. HP is huge. And he is dealing
with units that have some mass.
But, many of these newer tractors are mobile power, not
workers. Around here, with our steep hills I have seen old
iron from the 40s and 50's thoroughly embarrass new 4wd
tractors with twice the hp It defies explanation, but the low
rpm, high torque engines, tall narrow tires, on a heavy iron platform
combine to make a machine that will work way harder than the hp
would indicate.
Compare a modern 25 up tractor to one that's 70 years old
and you have a toy beside a tool.
