This is some information I received from the USGA.
1hour will equal 77 miles. Their rule of thumb is to replace 15% of the total replacement value of your entire fleet for new equipment each season. Say your replacement value of all your equipment is 1.1 million then $165,000 of new equipment should be purchased each year to have your fleet remain current and efficient. Hope this helps. I have a 17 year old fairway mower still operational. After 5 years of operation we try to at least replace our tri-plex greens mowers.
