HAND THROTTLES

what do you use it for, if you dont mind me asking ??

Had one in my International 6WD tractor towing 105mm Howitzer, used for travelling over rough terrain at a slow-steady speed,

I guess because they are a poor man's cruise control, but without the safety features of normal cruise control. Bods would have left it wound out and run off it at highway speed. Dangerous if things go wrong.

Like the others, I like using it off road working slowly over bumpy country, particularly with the 12H-t with it's very twitchy throttle.

never heard of them being banned even the nerw utes have idle up

they do ahve a couple of 4wd applications but there main purpose for existing is for PTO output

My 105 doesnt have one

Saves the manufacturers a few dollars per vehicle and 90% of owners will never use their 4wd for what it was actually built for so won't miss it.

Just checked with a mate who works for Transport SA vehicle inspection station.
Not banned, just phased out by manufacturers. No ADR to say you can't have one fitted.

Had one in my 90 Mazda Bravo - useful on rough ground in low range - rarely used but - definitely not a cheap cruise control !

Our bus at work (Toyota Commuter) has one. I wanted to fit one to my Hi Lux, same moter as the bus and they said it can't be fitted to it.

I heard they have been made obsolete by the fly-by-wire throttle controls. Their intended use was to stop throttle bounce on rough terrain at low speeds.
The fly-by-wire computer thingos do this now.
They were mainly vehicles intended for off road use. Meaning most earlier four wheel drives & later commercial four wheel drives.
I have had them & they were worth their weight in gold in low range for crawling over rough terrain or charging their batteries.

Not a poor man's cruise control, that is true, but oh how I'd like to have a "cruise control" that set the throttle opening rather than the vehicle speed.

As mentioned, acceleration up hills is often not what you want, just to keep the throttle opening and let the vehicle slow up a small slope, then regain speed to the desired level on the other side would be great.

That would help improve the consumption aspect of cruise control too.

With fly by wire controls it ought to be even easier to achieve.

If the safety aspects in a normal cruise control could be adapted to set the throttle opening at a chosen cruise setting I would be happy.

Of course I'd probably want both types fitted, to use in different circumstances, as well.

I have a safety question.

Does the hand throttle automatically turn off if you need to hit the brakes or whatever in an emergency?
