well, I was out scouting a D9 for a fellow chapter member but was not able to find a serial number on it as the back one was covered and what I believe to be the motor one was badly sandblasted. so I hope you guys can confirm what it is. it was pony motor start now it's electric. I would call it a direct dive model the hard nose has been added on after I think as it not very factory looking and the blade C frame has a shive mount left on it. someone has done a nice alternator drive for the old girl too.

I think it's earlier than a 18/19A. My 19 A parts manual shows two main air cleaners mounted side by side.

Single oil bath air cleaners were used on 18a1 to 2166 and 19a1 to 1585. Twin dry air cleaners were used from 18a 2167 and 19a 1586 to end of production. Field conversion kits were available to replace the single oil air cleaners with twin dry one.

Agree, just didn't investigate the s/n's that close on the first pass.

I saved this picture which is supposed to be a D9X as in experimental.Don't know much more about it.Just thought I would share it

thanks for the info I knew you guys could help me out. I sure do like the looks of that D9 you posted Gary looks a lot like a D7 hood and I always loved the look of the D7 hoods how the taper back to the operator. has anyone else heard the about a D9 with a single hyd cylinder just like what Euclid ran I have heard they made a small run of them with the hard nose were first coming out? or was it a conversion from the cable blades and just used the shive mounting?

Hi, mog5858.
I think that single blade lift ram arrangement was only for tractors fitted with a cushion push blade for pushing scrapers. The early DD9Gs had a similar arrangement on the rear tractor for traction control. Later DD9s did have it as they did away with the traction control after too many operators 'forgot' to disengage it when reversing for the next scraper.

Just my 0.02.
