Im sorry did I miss something when I wrote

The system relies on being able to turn wheels If you cant turn any wheels it will stall. If you didnt have the high idle (and remember idle speed is one of the functions of a govenor) to work up the turbo then it wouldnt work either.

Appropriately geared, fueled and given a high enough idle speed to give the govenor the ability to do its job you would never stall any diesel engine. But take away any of those things and unless you have a means of uncoupling the drive you will stall..

I think the Puma owners' have tried to suggest this.

urmmm so why do they stall in any gear thats not low enough to allow them to out drive the brakes... IF you want to apply that logic then Fozzy has exactly the same system because with 1200RPm on the handthrottle He doesnt stall out either, even going up hills off road because the brakes arent that great and neithers the tractability so the wheels just keep turning...

" If its only a govenor it can be stalled" Which it can't be, so therefore it is antistall???

Why do you choose not to believe that Puma's have antistall?
A direct quote from the LR site: " The engine is designed to meet modern emissions legislation and features an Anti-Stall device, which intelligently adjusts the fuel required when the engine is working at low speed."

The same brochure for the TD5 does not mention antistall. I know you are going to say it's just marketing guff but I ask my original question:
In a TD5 or earlier (instandard set up) in 1st gear low range, if you put both feet on the brake will it stall??

A Puma will not stall. Therefore it has anitstall.

Cheers,

ummm yeah it will..

in any vehicle fitted with proper antistall it doesnt matter what gear you try to stop it in it will not allow the engine to stall out proper Antistall disconnects the load from the engine. you know like the formula one car that richard hammond had a crack in. Im pretty sure the the crew chief made the comment along the lines of 8 antistalls? thats a record isnt it?

go out there put it in 2 low or any other gear and let me know what happens when you drop the clutch with your handbrake on (or if its stuffed your foot on the brakes)

why you insist on dropping lines like "adjusts the fuel required when the engine is working at low speed" that outline the definition of a govenor and then calling it antistall is beyond me.... (well its not really but lets pretend)

Nice job of cutting the bits out of one part of my post and putting them alongside another by the way...


I'm more than happy for anyone with a Ford Defender to bring it round and I'll demo quite happily as often as you want that you dont have antistall, what you have is a governed vehicle that in one gear has an Idle up so that the engine produces enough power to overdrive the brakes.

I have a 2008 Triton 3.2 DiD 4wd with a similar function.(Dont crucify me!) I havent seen it in the advertising blurb but have used it many times in the bush. I can just take off up any steep slope,my foot off the throttle, and it will proceed up idling giving maximum traction. If it starts to slip the truck will just sit there with the wheels turning slowly till it digs down a bit and grips again (hopefully).
However, it will stall if I put on the brake without disengaging the clutch, but one would expect that unless the brakes were shot.
