Video on Red Barn Machine Works. We started out with 92 HP and had to turn it down to 83 HP at 2300 RPM. Great torque back-up with 73 HP at 1650 RPM.

Congrats DrAllis & thanks for sharing. Great project & video. You’ve created the 100 series AC 433 engine tractor that AC could have built prior to their 6000 series.
I’m going guess that it’ll burn 3-ish? Gallon/hr plowing with 4-14? 4-15? bottoms… accomplishing 2.5-3 plowed acres/hr ??

Nebraska Test for 6080 tractor says 5.0 GPH at 83 PTO HP ( 16.68 HPHPG) output. At 45 HP it drops to 3.47 GPH. I dyno a lot of newer/modern engines and 20 flywheel HP for a gallon of fuel burned is about as efficient as it can get. Flywheel HP on a 6080 would have been in the 95 to 100 HP range (83 at the PTO) and at 5.0 GPH that 1978-80 engine was very efficient for its day. The 175 gas burned 5.1 GPH making 61 HP, where now with the diesel will burn 5.0 GPH making 83 HP.

DrAllis, your new 175xt has got me pondering.... Your prior post "moldboard-plow-sizing" theory ~ tractor pto hp= width of plow in inches? So it's 83hp = 83 inches of plow width. That would equate to a 5x16 plow(80 inches)? Has that thought come to mind for this tractor? Could it's drive-train hold up to it?
Here's a link to the post I'm referring to;

The transmission would be the weak link. Final drives are the same as the 180/185, so they could handle the chassis weighing 9000 lbs but I'm thinking second gear in the transmission wouldn't like it long term. Probably not the ring and pinion either. It's not all about the HP and torque. It makes a difference what it WEIGHS. But, yes. If the tractor weighed at least 100 lbs per PTO HP it would pull that size plow at a modest depth of less than 6 inches I'd say. Rear tire size would be pretty small at 16.9 x 28's. Optional 18.4 x 28's would be much better.

No. Been too busy with tractor rides to work on the 175XTD. I remember the tap discussion, but have now forgotten what it was for ?? Exhaust manifold pipe maybe ??

Thank you for the tap, Mike. I'm glad I went to the Amana Show. Saw lots of nice Allis iron and dozens of old friends. Thank you all for a very nice day.
