2010 550 XP harsh clutch engagement vs. what year built

After reading the forums (and personal experience) it appears some 2010 machines don’t have harsh engagement and some do. My wife’s was built in Nov. of ’09 and has what I’d call severe clutch engagement while my buddy’s was built in Jan of ’10 and is nice and smooth.

Anyone know what they changed to the clutching in that time frame to make it smoother?

What build date is yours and does it engage smoothly or harshly?
