Sarge 3,462 #4 Posted October 20, 2016 Don't try running a shaft adapter, either - the pto turns at 2,000 revs and will blow up 540 powered gearboxes... Sarge Share this post Link to post Share on other sites

Sarge 3,462 #6 Posted October 20, 2016 We had a local guy here years ago that had a D-200 . He had a machine shop make an adapter to run his 5' finish mower , which was set up for 540 - exploded the gearbox in less than 10 seconds , lesson learned ...lol . There are gear reduction boxes that could be made to adapt things , but be careful . Sarge 1 Share this post Link to post Share on other sites
