The only two I've used is bush hog 95% seeder 5%. I am restoring my sickle bar for next year though. It'll still be 90-95% bush hog though. I use lots of other implements in the 3 pt hitch.
I use the PTO for a tiller and a sickle bar...am currently shopping for a 4' rotary cutter...
On a side note...on my "to-do" list is utilizing the front PTO for an auxiliary power source...i.e., small AC generator head or possibly (12V) DC generator/alternator and an inverter...(got the idea from an old thread here...)
My favorite implement is the snow blower, but the bush hog is nice, I also have a cord saw which makes cutting fire wood a breeze, my Farmi winch makes hauling logs easy and lastly the wood splitter.
The only 3PH PTO implement I've run on the 1025R has been a 5' finish mower. It does a good job with it - already had it, so never bought a mid-mount deck (gotten pretty handy dropping/hooking up the loader & BH, the BH dolly really helps ). Pat's Quick Hitch makes life easier as well. The 3038e gets used for chipper & rototiller jobs.
