I ran a Case 680 with ( Air brakes) emergency brake was air control ( red nob on dash) the Case 780 had a ( hand operated) emergency brake. I was doing hoe packing and help backfill on main line sewer job. This was 1979. The Case 680 would LOCK up the emergency brake all the time( run engine at high speed) where I was to get ( Air pressure up) in what in my Humble opinion were ( Small tanks) that Case had installed on the Case 680 system. It always locked up emergency brake on say lots of rear wheel brake turns. I started digging the side sewer stubs. We had the Case 790 for that. We also had a 190 Dynahoe ( my favorite) the Case 780 never Locked up it's emergency brake. Hand operated control lever on floor. It was still ( Air brake for tires) the Case 780 did NOT lock up or stop in your tracks when using rear brakes to turn. You could keep working, just low air pressure buzzer alarm going off. The Air pressure on Case 780 would build up faster than 680. Going back to 190 Dynahoe, was worried when Foreman left me at it one day, to dig side sewer stubs. I was all by myself looking at this new backhoe to run. It had been converted to two lever joy sticks ( twin- a- troll) BE name for them.. Not the 4 lever standard Factory BE control. I got on her. What a joy to drive. The simple fluid lock out electric control for rear braking. ( Switch on front loader control lever) for left or right braking. None of the AIR problems with brake lock up on backfilling my side sewer stubs, in the muddy dirty off the right of way, using your rear brakes to fill over ditch. Anyway LIKED the Dynahoe 190 so much. I bought one in 2003. It had 8000 hours on meter. I have put 100s of hours on that good old Detroit 353. Other than seal Leaks on Hydraulic cylinder. I replaced all Hydraulic lines myself weather they need it or not. They were all old. The Dynahoe was a strong machine. Only one that stand up to hard work with bull prick ( Jack hammer head) or hoe packing with vibrator plate. That's my story with Air brake system on Backhoes. Strange how same company CASE built emergency brake air system in 680 but had standard pull brake in 780 for emergency brake. The 790 case were huge. Long stretch for outriggers. The problem with the one that I used. It had muffler leak at base. That smoke sucked into air intake next to stack. It would plug up all the time. Engine would starve for air. Boy all the things you learn on operating these pieces of equipment. Just like your video. These are great learning tools for a guy that has one of these for Restoration.
@@deserttrucktractor2514 ok. Entiendo. Pensé que era Allison. Supongo que no se consiguen repuestos. Me están vendiendo una, pero tengo el temor de no conseguir partes.
