Oliver 66 and Super 66

[bv]

what are the differences between a 66 and a Super 66, engine, transmission and rear or hydraulics?

Engine 129 ci vs. 144
Belt hp 27 vs. 33.7
Drawbar hp 22.5 vs. 28
6 volt vs 12 for gas models

Don’t know about the rest of the drive train but would guess they are the same.

Super had larger rear axles.
Super had mounting pads on front of frame to mount implements....James

I believe the hydraulic pump would have been different on the Super than on the earliest 66s. I can't say on the last 66s. Another thing, the early 66 had a smaller steering wheel like the 60 had, but then, the later 66 had the larger one like the 77 and the Supers. Early had band brakes and small pedals. Bottom line, there were several changes during 66 production, so more differences in the early 66 and the Super then between the late 66 and Super.

Early Super 66s had a small battery door like 66s, later had big battery door. 66s had same belt pulley as 77 and 88s. Super 66s had a much smaller belt pulley. Both models used 15 inch front rims, but 66 used a slightly different style that Super 66 did. Headlights were of a different style on both and no more dash light on Supers. Electric levers on steering column, side mount levers, or both on 66s and top load on Super 66s. These all off the top of my head. I'm sure there's more. Both fantastic tractors. I was brought up with them.

I’m going to add another question to this discussion that falls in along similar lines.
Aside from the horsepower increase, what additional improvements did the 660 have over the Super 66?

I posted that its probably down a few threads about a month old. Answers I got was manifold, carburetor, RPM's From what I got nothing earth shattering.

OK, thanks. I missed that one.
