d 2 help

i need the specs for a 1954 d2 I have on a dyno right now rpm,pto rpm, all that stuff thank you

Here is what I have....

How about any pro specs ? Have a dyno that hooks up to the pro so I need rpm,hp. If possible thank you

What's a pro? If you mean pto the only spec I know is the 540 rpm output unless your dealing with a two speed pto.

Hi Tim,
best place for real life tractor test data is from the Nebraska Test site.
Hope this link works--all be it for the first release of the U Series machines and is Test No 418.
Most spline shaft PTO's are direct drive thru--if not (as OM alludes to) and if it is geared you will have to calculate the gear ratio change thru the PTO into your Dyno readings.
Hope this helps.

Cheers,

Just a reminder that D2's and D4's are not direct through drive to the pto. There is a single gear drive involved with each.

Thank you yes pto.

He was looking for high idle rpm, then load rpm and hp at pto,at given rpms at given hp. Trying to dyno it like farm tractors and can't find specs like that

Yea specs like that can be found on the tractor data sire that list the Nebraska teat results for the D2.
