“Crawl” mode

With the manual gearbox and the lack of a low-ratio or suitably low first gear, I’m sure we are all used to putting the car in first (or reverse) and letting it crawl up steep slopes without any input from the accelerator pedal. But does anyone have any idea just how steep a slope it will handle without stalling? I know it copes with ease on a 15% gradient, but how much steeper will it handle? 2005 D3 2.7 Auto

The maximum slope is probably around 15° full tare weight including maximum towing weight from a standing start. So for the Freelander 4505 kg from a standing start on 15°.

Obviously tackling difficult 4wd tracks it would be wise not to tow anything. I did about a 35 degree slope, it was not too difficult but having an automatic allowed me to take my time avoiding minor obstacles on the track but in general keeping momentum up & the ground was firm.

Best to have an observer so you can get feedback for minor corrections, but plan your path to start with. Preplan a retreat route.

Correct tyre pressure will do wonders! Procrastination, mankind's greatest labour saving device!

Thanks. I’ve not tried standing-start to crawl on 15%, I’m not sure the manual will handle that. The anti-stall seems to need to sense the situation for itself, and even on the flat needs very sensitive clutch work to pick up properly. Since crawl is at about 800 rpm on mine, doing the hill-start with the micro clutch adjustments would probably be into smelly-clutch territory. Getting down to crawl from having accelerator input, without a complete stop, is not easy, so it is also quite tricky to drop from normal hill-start down into crawl. It doesn’t seem to crawl in reverse nearly as well, I guess the reverse ratio must be higher than first? 2005 D3 2.7 Auto

A few years ago trying to get out of a caravan park at Lago di Garda with relatives we cooked the clutch. It was not that steep but with 3 people pushing we just got out. Procrastination, mankind's greatest labour saving device!

Crawling at 800rpms with a manual? is that possible? Max torque is achieved around 1600-1800rpms, so operating in this range in 1st gear would be the optimal crawl/offroad speed. Am I wrong here? Going slower need riding the clutch, and that will ruin the clutch pretty fast...??

I remember reading somewhere that LandRovers are supposed to be able to start on a 1 in 3 (or 4?) hill. Apparently it was one of the issues when BMW owned them in that the BMW engineers couldn't understand why it was necessary, the answer "because it's a LandRover". 3 x FL1 2 manual + 1 auto

Simple question: How is the best way to get up this hill with a manual without stalling the engine and/or ruin the clutch? Going in the so called "crawl mode" mentioned here would just stall the engine. There is not enough torque to get things going at 800 RPM`s. Correct me if I am wrong Smile

Pray that you still have inflated tyres at the top!

The photo below I inched over the rocks & this was level ground. I would not have given it a go in a manual as you have to move far too slowly.

That FL1 looks to be doing OK although I did notice when I had one that first gear was very low to make up for lack of lo-range box. FL2 gearing in a manual was not as low as far as I recall. 3 x FL1 2 manual + 1 auto

Hi,

I have driven up that hill 4 times now together with the local LR club. It went pretty well and tires are all OK. My technique is to stop at every level "flat", study the terrain towards the next "flat" and plan the route. Then when the course is clear, release the clutch fully and aim for the planned route with the RPM at around 1800 to have max torque. Things are then going a bit fast, but this works!
The FL1 in the picture overheated where it stands. The driver did not use my technique and ride the clutch to much. It smelled bad. It had to be towed aside by a V8 Defender. The old series LR which you can see in my mirror just crawled up easily all the way as it has the low range box.

Here is a video, showing the terrain our club has access to:

my first ever 4x4 was a MK2 Frontera 2.2 DTi Limited. Manual 5 speed box, on the fly switchable 4x4, and a low range box.

I took it on an organised greenlaning day in the Peak district which involved going down the tarmac road at Monsal head, crossing the bridge over the river, and then up the lane going up the side of the hill opposite the pub/café above the viaduct.
Low range, 1st/2nd gear, feet off pedals... it went up with no problems what so ever.

Did the same hill a couple of years later in the my 1st landrover, a 2001 FL1 Auto, in manual 1st/2nd, but at a much higher revs/speed than in the Frontera meaning a bumpier, crashier ride and quite a few wheel spins.

IMO you cant beat a proper low range box for low speed crawling.

That is correct! I guess that is the main reason why the FL 1 and 2 are seldom seen when the big boys are out playing Very Happy D:

the group I used to go laning with used to split into 2 separate groups, the soft roaders who did the less challenging lanes but still pretty tough in places (Freelander, Japanese, Korean etc) and the big boys (uprated and standard Japanese stuff, Defenders and D2) who did the big boulder crawling stuff like Stanage Edge

Unfortunately the eco crowd targeted them with online and actual abuse, so they folded their website. Even though they were responsible in their routes etc. and careful not to tear anything up.

It’s completely possible! I’m not suggesting it is the best option for all surfaces or situations, and if you are needing more torque, then yes, a higher rpm would be needed. But in first gear (actually in any gear) with your feet off everything, the car’s electronics are pretty good at preventing a stall. In some situations, because the FL2 has quite a high first gear, I find 1600-1800 revs is too fast a road speed for manoeuvring. Letting it work away on its own means that there is no need to ride the clutch and less risk of clutch damage - I assumed this was a design feature and part of the learning curve in moving from a low-ratio and diff lock situation over to electronic bells and whistles?

It does seem to need to know that it is being asked to do this, though, so unless you let it pick up on its own from rest, you need to ease it down to the crawl revs with a bit of clutch use. Interestingly, though, the engine is not at tick-over revs, but somewhere about 80-100 rpm above resting tickover. 2005 D3 2.7 Auto
