Secondly some of you say that you have to choose the correct ratio but how do you do that on a JD?
Pull the stick back.

But everyone says a vario is inefficient so you would think it offer more engine braking ?Yes but could there not be other factors at play as well , such as the different transmission drags .
Back in the day and may well still do but I haven't been to one in years . If a car was getting dyno tested it would do the run and then the clutch pressed to measure drag as it coasted down , to work out engine output .
Could the same be happening here and making it "feel" the vario has less engine braking , added to his valid explanation?
I am convinced rightly or wrongly there are factors at play here . Take my baling example as have never used the t3 dyna 6 6480 on sprayer. Vario set to sv1 7kph lugs down to say 5 going up hill. Sv2 could be set to 3kph expected to run off slightly and hold itself back to well bellow 5kph but cannot in my experience and take off over revving high enough to throw a fault code if left un braked . D6 can in similar circumstances .
Edit here as see the duck has answered on exhaust brake being at least a benefit [emoji106].
My comment is an exhaust brake would be a benefit but also agree it would be a benefit on any gearbox .
Yes Andrew, of course you can pull the stick back or take your foot if the accelerator to slow down but choosing a ratio?
Presume you’re referring to the power conversion efficiency (hence losses through the hydrostat and hydromotor(s)? If so then in terms of increased braking efficiency- it would amount to the sum total of diddly squatBut everyone says a vario is inefficient so you would think it offer more engine braking ?
Our new Merc 1835 truck is the same, put 8 ton of lime on the back and there is little stopping it, even the exhaust brake struggles to contain it.The duck explained it further back in the thread
It's to do with Internal egr on the exhaust stroke of the engine that it doesn't offer the same level of hold back
Do your fendts have good engine breaking?The duck is not always right ,gets red mist from time to time from his days in the brain washing camp
Think fendts have a history of engine breaking!Do your fendts have good engine breaking?
Think you have spell exhaust brake incorrectThink fendts have a history of engine breaking!
Big Reds. And some people said multi power was a bad thing...will this have engine braking on it ?
I've never understood that one tbh , other than over revving the engine like when dropping gears to quickly with anything .Thought some problems users get with vario is when transmission is used to slow speed rather than tractor breaks ?

It's like in my car use the breaks before change down a gearI've never understood that one tbh , other than over revving the engine like when dropping gears to quickly with anything .
It gives transmission a bit of shock if change down gears at high speedIt's like in my car use the breaks before change down a gear
Exactly , no reason for any shocking with a cvt as no need for clutch , so only engine revs to watch using a cvt to slow down surelyIt gives transmission a bit of shock if change down gears at high speed

Any tractor with gears it's case on the breaks first easy of foot pedal then down the gears,Exactly , no reason for any shocking with a cvt as no need for clutch , so only engine revs to watch using a cvt to slow down surely
