Hello,

I was just reading the topic 'Drive Train Strength' and it got me thinking! What kind of weight or object or thing (on the higher end of the scale) can I pull / push with my 2.5 N/A? I'm intrigued as to how useful my engine could be when needed. Would i be able to pull a car out of a deep ditch? How about pulling an artic truck? Please put my inquiring mind at rest!

low your **** a car out a ditch, don't try an arctic as mate of mine, eaten range rover classic rear diff doing it
 
Well I pulled a double decker bus with one befor :) . and with my 2.5td pushed a 3.5 ton forklift 200 mtrs back into the works garage 2 weeks ago . its just the weight on the wheels ( or lack of it ) that lets em down .
 
I asked this before and apparently pulling 50 100ton coal trucks is not a problem hence "pulls like a train"

Thanks for the replies :) Well at least I know it's useful when in need!

The trick is to use the lowest gear you have, the lowest engine speed, get the clutch all the way up (no clutch-slipping when heavy pulling) and see what happens.

There are several options:

1. what you are attached to comes with you as far as you want it to. Point made. Every one should be suitably impressed.


2. the tow rope snaps. Use a stronger one. NEVER use a wimp towrope.


3. the tow-hook at one end comes off - very dangerous. You may get smacked in the kisser by a tow-ball and / or a big D-shackle.

4. nothing seems to be happening but the rope is very tight, and the funny thing is, some of your wheels are turning!


5. you stall your engine - so try again, and this time start off with a little slack in the rope so it takes up with a SLIGHT jerk.

6. sure as death there are other things can go wrong, like you break a half-shaft, your diff explodes, your wife phones and says if you aren't home in ten minutes your dinner goes in the dog, your girlfriend appears all dressed up for the date you forgot about .....

In your lowest gear (low range first gear - don't use reverse as it will break sooner), the TRACTIVE EFFORT that any Landy can apply is HUGE, because the TORQUE from the engine is multiplied over FORTY TIMES. You can tow huge loads, but you will have to do it SLOWLY. In second gear the torque multiplication is barely HALF of what it is in first, so with a really heavy load on, stay in first gear and just take your time. It's not a race. It's a heavy pull job, and taking more TIME lets you use a lower gear, and maximum torque multiplication.

Before he had his, it was mine, and I towed an army 50 kva generator trailer weighing over 4 tons nearly 50 miles back to my place. The genny engine was a HUGE V8 Perkins diesel.

The Def 90 had a 2.5 NA Sherpa engine in it, about 75bhp max.

It had fifty gallons of white diesel in the genny fuel tank, but not for long.

On the run back was in low range until I hit the motorway and then it was a slow drag all the way. It just takes a little longer, but it still does the job.

I've inquired with my insurer re. a 200tdi :) It'll be interesting to see what they say.

I bought my 90 from Charles, so he was talking about when he towed the genny with it on the 2.5NA Sherpa 15J (which has a few more ponies than the 12J version too) when he owned it.
 
I towed a builders skip fully loaded with clay, rubble, and water, along the road for more than 100 yards with my old 2.25 SIIa SWB petrol landy. Dont know what it weighed but it moved with no problems. Noisy though - may have had something to do with not having any wheels on the skip :D Skip lorry driver wasn't too happy either but that'll learn him for dropping it across my driveway while he had his breakfast. I was hoping the bottom would fall out when he lifted it but alas I was disappointed. Should have pulled it a bit further.

As CharlesY says - take your time and let the motor and gears do the work.
 
Was helping some friends with a skip once, one of the big ones with doors and things on it, the guy put the back against the wall then the people using it started filling it from the diagonal side, needless to say they then realised they needed more space and the back was a big air gap. Stuck a skip chain round its two lifting lugs and dragged it back far enough to get the doors open. 1st, low, foot up off the clutch let it creep away and just left it, bang chain went tight, then scraaaaape.

That skip has some heavy stuff in it I tell you.
