Southeast Washington | Yes we have engine braking on our 620 quad. It pulls the sprayer and a grain cart so is very welcome to take pressure off using the brakes. The old Case IH tractors didn't have brakes worthy of holding back a load on the hills so most running those on carts added a Jake Brake because one disk on the driveline isn't sufficient in hills. The STX was a welcome upgrade to real brakes.
It's like the trucks, once you have an engine brake it is hard to go without. For cart work people will grab the engine brake tractor first. The problem is though for heavy grunt work you are going to grab the C18 Challenger first.
I know I'm beating the horse about CVT in big tractors since it is relatively new and the quad does have issues that keep it from being the clear takeover. When you depend on one tractor to get the seeding done you don't want it down when it is go time. I do know the manufacturers do watch this stuff and will contact you from time to time.
When the power shift option has been taken away you expect good testing to show you the answers. From what I heard the Fendt tested in the area played some in hills and then shipped back to the factory for inspection. The main mechanic for the dealership didn't see it run or hear how it performed. Keeping tight lipped other than to say we tried breaking it but it didn't doesn't assure potential owners.
Anyway some more pictures for the heck of it.
Edit to add: yes brakes are used pulling an air cart downhill with the shanks in the ground. An engine brake would be nice for that too.
