Yes, particularily snow blower and rotary broom.on a tractor that size it is more likely used for front mounted attachments.
I bought my tractor used and the seller had already swapped out the mid pto from my tractor L4740 to his new L6060 so the mid pto parts even interchange between the 40 and 60 series.
I don't have any front attachments that require PTO power so I don't need the mid PTO.
