Help identifying grader

Hi, Folks.
I have my suspicions, one of which is that it might be missing an engine. Dunno why I would think that, unless it's that control box with all the levers sticking out of it. Another suspicion is that it might just possibly be a Cat.

Just my 0.02.

It's cheap enough, buy it!

Adams leaning wheel looks like it has a power unit to run the controls

Could it simply be a PTO drive off of the pulling tractor?

Could it simply be a PTO drive off of the pulling tractor?

Yes, i would agree that is is a Adams.

that very nice and for the price. if we where not digging out after a 2 day blizzard i would be on the road that way lol. it is powered but a PTO as you can see up front on the neck so i would say the towing cat would need PTO as well.

Definitely a pull type non PTO assist. The upper draw bar does have a hand controlled gearbox for front wheel lean.

The majority of the controls are set and forget hand crank and the pull leavers could be the on the fly controls for the large gearbox which looks to be ground driven as seen in the second last photo right side through a 90deg drive to the rear axle but this is the shaft for the leaning wheel aspect of this vintage machine. The hand crank at the centre of the rear drive box means it's human powered. You can retrofit this grader to be hydraulic motor assist be adding a coupler/mount/hyd motor to this hand crank. Motorless for sure. Look up

Adams 125 Leaning Wheel, Pull Type Grader

or...... added to remove the theory of PTO drive

Looking at the main backbone frame of the unit, it Most likely not be, PTO driven from prime mover to rear gearbox. The drive system would be a straight shaft from PTO to an under slung drive shaft from the draw bar on this grader, to a double 90 degree drive in the front axle neck to a short driveshaft inside of the tapered part of the backbone frame supported by a hanger bearing to a longer straight driveshaft in the main part of the backbone into the rear drive gearbox which would output to control levers for shift in/out control and then to the 90degree drive (as seen in second last photo bottom right side of gearbox) to the rear wheels for assisted mechanical rear wheel drive (taking a breath) sounds possible but Way Way Way over engineered and complicated for its time. Or it's a pull type with manual crank controls, lever controls are human powered as seen in the photo. Nice piece of military history

Interesting for sure and would make for an epic lawn ornament all restored or work her instead of a box scraper

Most likely an Adams Leaning Wheel Pull Grader...They had a 5hp Wisconsin engine to power a hydraulic pump for the controls...
It appears to be larger than the Adams 134...all manual...with rubber tires...that I have...
A few years ago, there was one of these down here in Texas...Someone bought it for yard art...
It is well worth the asking price...Don't let it go...It's a rare piece of equipment...
