Gary & Two Bit - The posts are 8ft to start with which means the Atlas Copco hydraulic pounder handles are at 9ft. I'm not that tall. There is not a chuck that is shaped like the post profile for any pounder so I use the larger round chuck with a post cap so it does tilt a little bit. The pounder is ~80lbs. I could possibly use a ladder but my cycle times would go way up. I did not mention this before but I have 1400 posts to put in and I can get 70 done in a day and that is with hitting rocks and repositioning if need be. I'll dig out a pic later to share.
