Tractors with Most Hp and Best MECHANICAL Brakes

The Farmall 756 gas died on me going up a very short transition slope from one field to another. I was going slow and it just quit. I rolled
backwards about 15ish ft until the flat field behind me stopped everything. This tractor has excellent brakes, but when the engine died, they
either didn't engage or the lack of hydraulic assist made it impossible to stop the tractor timely. Good thing I wasn't on a long hill stretch - which
we've got or had a tow behind wagon, rake or baler.

Question is - what make and models of tractors that have higher hp have mechanical brakes that will slide the tires when you mash them -
engine off.

Thanks!

None of the self energizing dry disc brakes seem to work very well in reverse, most don't even work that well going forward.

Only ones that I ever ran that was mechanical and consistent were the Fords, 5000 through 7710, they are a wet brake as well.

8000/9000 and similar Fords are manual, but are hydraulic with a master cylinder.
 
My brother has a 756, it's an outstanding workhorse BTW, but it also seems to have almost no brakes when the engine stops. My 766, while appearing to have very similar brakes, seems to have pretty good braking in such situations.
 
Oliver 1650, 1750, 1850 and 1950 had mechanical brakes. I think the AC 190XT had mechanical brakes. Not real sure, but think MM 670 and G1000 might also had mechanical brakes.
 
If your brakes are working properly on that 756 you will have very good brakes with no hydraulic assist. That was one of the things that was demonstrated to us at the very first service school we had after the 7 & 806 were introduced. They had the test tractor equipped with many different valves and hoses so they could simulate different problems, like not hydraulic steering, free wheeling, brakes etc.
 
Case 30 series up to the 1030 had mechanical brakes and will slide the wheels if they are in shape.
 
Yeah, and I near got killed on a 1970 3020 when I lost all brakes and steering coming down a steep hill. Many had/have weak or dead accumulators. I will never trust my life to one again. I still curse that day when I was moving a lot of heavy equipment with my old slow tractor with mechanical brakes. My neighbor kept bugging me to take his 3020 instead because it was so much faster. BIG mistake. Coming down a very steep hill, trans popped into neutral (SynchroRange), engine stalled, NO steering and NO brakes and picking up speed fast. I climbed out and jumped off just before it left the road and crashed. Broke both my legs sideways and my right foot came right off. If I had stuck with my old IH with mechanical brakes, steering, and conventional trans - I'd be walking a lot better today.
 
My buddy was baling up a steep hill with his 1066 and ran out of go - didn't get the clutch in quick enough, and it stalled. Him, the tractor, a 570 baler and kicker rack went backwards down the hill in a big mess.

On some tractors, continually pumping the brake pedals with the engine off can build some brake pressure, but not enough to equal the brakes with the engine running (Deere 4020, etc.). Most larger tractors made in the last forty five years will have power steering and power brakes. Like cars and trucks with power steering and power brakes, those tractors will all be much harder to steer and stop without engine power.

Safe operation in hazardous situations is to shift down and and keep engine RPM in the mid-range or higher to maintain control functions. Stalling-out on a slope is very dangerous and is considered an operator error.
