Hand Throttle on MY12 Defender?

[Nicholas]

Is it possible to fit a hand throttle to a new Defender? Will it act as a quasi cruise control?

May be a less precise but way cheaper alternative to an aftermarket electronic control.

Any advice would be appreciated.

The TDCi is "drive by wire", (so unless you want to connect something directly to your accelerator pedal ), no.

the flybywire vehicles make it easier sometimes, there are a few vehicles that use the throttle pedal and link to a pull cable with graduated stops for this application, toyota for one.

A simple system like that probably doesn't automatically disengage when you touch the brake. Could be dangerous.

I can tell you that when I was a passenger in a friend's Series II and he decided to use the hand throttle as a cruise control somewhere out near Broken Hill, things got pretty interesting when we came over the crest of a slight rise and found a mob of sheep blocking the road.

sorry just reread the OP, no! do not use it for a cruise control!!

I want a "hand" throttle for when I'm using the winch, or wanting a very steady low speed, for arguments sake, say going up a rocky section of track, would using like an old mower type throttle cable be ok do you reckon?
I had a wind out hand throttle on my old 75 series toyo, (fitted from new at the factory) and yes, a as cruise control, was a nightmare,,

There are hand throttles on the veteran cars, absolutely ****** dangerous to use as a cruise control, don't do it. I'd hate to see what the insurance company would have to say when you become unconscious after running up the back of an L plater, bouncing off the steering wheel and taking out the opposite two lanes when travelling down a dual carriage way, sure for small offroad applications to be able to bring the revs up ~ 250 rpm is good, but cruise control is a big NO NO. Needs to cancel on the brakes. Just fit one of the aftermarket systems, maybe you could do a little hotwiring to make it work at low speeds (low revs) and in neutral, then it could be used offroad and also safely on the road.

Actually a hand throttle would be handy in low range crawling.

The cruise control won't work in low range.

I really would like hand throttle on my TD5 for winching, also would be handy to have a pot in the engine bay to give the engine a rev when listening to noises.

Thinking of running a pot in parallel with the pedal pot and see what happens.

Why does it not work in low range, is there some kind of switch?, otherwise i can't see any reason a sytem couldn't be adapted to work in low or as you say just put a pot in parallel, you could have one in the cab on a screw like in a cruiser, would be really good offroad.

I don't know why but as far as I know, no cruise control will work below 30kph.

The more I think about it a pot on the dash with a missile switch to isolate it seems very useful.
