Caterpillar Dozer vs 20 Toyotas in Tug O’ War
Not all fights are fair. So when we see twenty – count twenty – Toyota J30s and J40s lined up along an I-beam against a single Caterpillar D8 bulldozer from the same generation – we know the odds are stacked heavily. And just like in 480 BCE when a few Spartans held off the Persians, the Caterpillar D8 bulldozer does an admirable job of keeping twenty Landcruisers at bay. It’s been pointed out that they had the Cat D8 bulldozer simply dropped its front shovel, this race may have had a chance of going a bit differently. And indeed, the biggest surprise of all isn’t who won the race – it was the steel I-beam that managed to remain straight throughout the fight. But I-beams don’t get credit. Toyota J40s do. And just like both the Spartans and Xerxes army – both had been relegated to the annuls of history prior to this reenactment.
The classic J40 Landcruiser was produced by Toyota between 1960 and ending in the early 1980s. Hearty, good looking and rugged, it’s a wonder why Toyota ever got away from this reliable four cylinder off-road truck. The first series of J40s produced in 1960 had a 3.9 liter F engine which generated 125 hp. It was the upgrade to the J20s and 30s Toyota produced before then and it served a very good role for both civilian and government needs. A fuel efficient four cylinder design enabled this vehicle to make grand off-roading excursions.
Not powerful enough to pull trucks out of ditches or push through too many obstacles, it was still ideal for coasting through muddy slopes and bad terrain.
Caterpillar is an industry leader in heavy duty equipment. And this is shown in no better place than their bulldozers. Tough, reliable and capable of moving massive piles of eart
The last American models of this truck arrived in 1983. By that point, they were considered a rarity as the predominant market for these vehicles was South America, Europe and parts of Africa.The 1980 upgrade brought alongside it a 3.4 L 3B engine powered by diesel fuel that put out 90 hp and 160 lb-ft of torque.Minor by comparison to today’s diesels, it still had a reliably powerful inline four cylinder form factor that made it attractive to both off road enthusiasts and mechanics.
Caterpillar is an industry leader in heavy duty equipment. And this is shown in no better place than their bulldozers. Tough, reliable and capable of moving massive piles of earth, this one held the classic S-U combination blade. That stands for straight and universal – two different blade times combined into one form factor. Modern day Caterpillar D8 dozers feature an extremely powerful D8T ACERT engine which replaced the older D8R Series 2. More engineering went into the creation of this engine than likely most of the variants of the J40s shown in this post. However, at best it only has 310 hp – perfectly reasonable for pushing clay pan and rock into finely graded rows.
Let’s Do the Math
J40 variants averaged around 3,500 lbs curb weight. Subtracting the I-beam as the seesaw for this little bout, that D8 had a tall order of 70,000 lbs he would have had to pull in order to win. If the Caterpillar D8 bulldozer came from roughly the same era as the J40s, then it would be likely the D8L or D8K. In either case, that’s 300 to 335 available horsepower. A single J40 would average a maximum of 90 hp. So, it would be 335 hp versus 1,800 hp. The Cat D8 weighs approximately 80,000 lbs. So, in essence, it was a somewhat equal fight in terms of weight. And an entirely uneven fight in terms of engine power and performance.
