If you only need the power unit you can get their TS360 cutoff saw (around $300 used $600 new thru the internet) and it's the same powerhead.. you just need to modify the trigger
all the hard mounts are the same and lovejoy coupling is same it takes about an hour to swap
They also make a Tractor mount PTO Powered unit that has the same gearbox the bt has, just unbolt the pto power head
put your handle & power unit on and you have a New cranker
hope that helps
