Straight 8 speed transmission, 451 engine at 125 factory horsepower, 540 and 1000pto, outboard planetaries, heavy 3 point hitch, dual cylinder power steering. Have had a 1170 since 1979...bulletproof tractor and mine has been set at 150 hp for many years without drivetrain or engine trouble. Only downside is they aren't shift friendly...straight cut gears, good tractors.
 
A very trouble free tractor. A work horse. I wish I had the one dad bought in 1973. That tractor did not know what a shop was. RB
 
I tend to get in trouble for mentioning cons but regarding my 1170 that I have had for 40 years, the pros definitely out weigh the cons. A very good workhorse but here are the cons that I find easy work around.

Its a manual tranny without synchronizers---- which allows "gear-grinding". Therefore, some patience and an idling engine is needed to get it from neutral into any gear with "acceptably" gear-grinding. Shifting from one gear to another quickly is easy and no gear-grinding at any engine speed.

The top of the air cleaner decreases forward visibility but not a issue unless you are short and trying to sight directly forward.

My 1170's cooling capacity is only adequate for full power up to about 95 degrees.

My 1170's power steering turns easy with one hand unless I need to turn the steering wheel fast. With out a spinner, it takes both hands. This may be an adjustment problem only with my tractor. Its a minor problem that I have never felt inclined to check out.

The dry brakes are adequate 99% of the time. Turning sharp, for example, finishing till a small triangle and having to turning often in the same direction the brake being used will start to smell overheated.

The Master clutch is a dry clutch and therefore easy to overheat---for example when trying to start a tillage implement fully engaged in the ground. I simply raise the implement and back up 10 feet and start again with the implement still raised. Typically, its easy to figure out ways to not burn the dry clutch when getting a heavy grain cart moving.

I think the sight gages, to check the oil level in the tranny, are the pits. there is a rather simple remedy for that. I made a dip stick to use through the oil fill at the back.

My tractor needs the right side brake bled if it set for more that a month. It may not be a common problem.
 
One of the finest tractors Case built, if you like to see a new one, go to my post in 1030s, as there was a new "1175"s sitting close to the farms "1030"
 
Id love to see the dipstick you made. I have a 1973 1175. I hate those sight glasses. Any way you could send a couple pictures and measurements?
