This took some getting used to and this is also why some trucks have the 'jake brake' Plus in NH shifting into neutral to coast is illegal. I think this is similar to regen only when you step on the brakes to provide no drag when 'coasting' However on my E15 with Alltrax I like the regen because when I go down my big hill it helps maintain my speed, on a tractor I don't want to accelerate downhill. |
