My L3600
With 60" Blower attached
Also I found this vid on You tube for you to have some good solid info about hooking up 3pt implements in general

You have a Cat 1 hitch BTW and you can easily handle up to a 66" blower the 72" is a maximum according to the specs.. The little arrow mark on your tach at about 2400 RPM means your PTO is spinning at 540 RPM which should be correct for most rear blowers.. You have a little over 31 HP at the PTO
Biggest concern for using PTO power,,, It stops for nothing, NEVER get out of the seat of the tractor with the PTO running, the little lever on the right side of the seat above the 3Pt lift lever engages the PTO, save wear and tear and engage at idle then rev up to operating speed, before moving the tractor, slow and steady wins the race when blowing snow, going too fast, or bumping snow banks, breaks shear pins, which wastes more time then going slow and steady
A pic of the blower would really help also or at least the specs...
This is a vid from the other day with the L3600 moving some really wet stuff off the road, it is actually raining while I am working

Around the curves I run in 2R or just over 1 mph, on the straight shot I shift to 3R or just under 2 mph sounds slow, until you are driving, but sticking it in a ditch really slows down the process
so I take my time...
