Tow­ing & haul­ing

Farms & Farm Machinery - - New Equipment Test -

One of the big­gest as­sets of a diesel en­gine is its abil­ity to lug a load.

A cou­ple of years ago I had a yarn with Dr Wolf­gang War­necke, the chief sci­en­tist for Shell’s global mo­bil­ity fu­els divi­sion. Aside from be­ing a Un­i­mog tragic, he also had some in­ter­est­ing things to say about diesel en­gines.

“As far as ther­mal ef­fi­ciency un­der load is con­cerned, there’s noth­ing bet­ter than a diesel en­gine,” he said. “Light ve­hi­cle fu­els may change in the fu­ture, but in heavy com­mer­cial ap­pli­ca­tions noth­ing comes close to a diesel.”

We then spent a lot of time waf­fling on about Un­i­mogs and hunt­ing.

The Y62 Pa­trol has a de­cent 7000kg GCM which makes it a walk-up start for tow ap­pli­ca­tions. How­ever, it would be fair to spec­u­late that, while it will haul a load ef­fort­lessly, the Nis­san will no doubt drink a lot of juice to do it with peak torque so high in the rev range. The fuel fig­ures quoted in this story are based on a loaded wagon tip­ping the scales at about 3000kg.
