Can anyone give me the ground speeds for one? I can't find the speeds anywhere. Friends looking a building a puller but don't know what the ground speeds are. Or could anyone tell me what the percentage of drop a power director drops ground speed? Thanks guys!

Thank you Gary! I tried tractor data for the D-12 . It only shows the series 1 and 2. The series 3 had the high and low.

D10/12's never had a Power Director. The series 3 models had an optional Hi/Low auxiliary transmission ahead of the normal 4-speed.  With 12.4 x 24 rear tires @ 1650 RPM in direct drive the speeds are 1.9- 3.7- 4.8- 12.1 MPH. This would be the same as normal 4-speed tractor speeds...direct drive.  When shifted into Low (under-drive) the speeds become 1.1- 2.2- 2.8- 7.1 MPH.
