In general there may be an ideal HP/weight but I feel CUT’s are expected to perform more diverse tasks so the ideal HP/weight and Hp/pto starts to become blurred, when the capability is separated by HP only!
When I purchased my 1720 SSS it had a FEL and an RM-59 finish mower and more than enough power. It had the weight & mechanical capabilities to handle all of what I needed to do.
My new 60” snow blower highlighted the HP issue. It requires excessive clutch use to prevent stalling when making the first pass down the driveway, and it’s particularly difficult at the end where the State plows roll up a deep compacted bank.
Winters are cold and the winds are constantly changing and I wanted to get-R-done and get inside but lack of HP prolonged the agony. And yes; I had the transmission in 1st gear and the engine was not low on OEM power!
PTO powered attachments don’t need to be heavy to require significant HP.
Additional HP has always been on my wish list. The HP issue was solved with the addition of a turbo. I no longer need to use the clutch to prevent stalling; I now have the tractor I feel it should have been from the start.
Recently I acquired a 60+ inch rototiller that covers the width of my tractor.
I have been chipping and have a huge pile of chips that I’ve been trying to compost and the rototiller is perfect for turning grass into it.
Without the additional power it would not have been possible to run the rototiller at the required depth to turn my compost.
My tractor also handles my RM59 much better and has a huge torque reserve when I encounter thick heavy grass. I’ve found it to be much more responsive to sudden loads when mowing, snow blowing or running my 25KW PTO generator.
