I have seen some nice older rigs that have been well maintained but they have so little horsepower compared to today's average tractor. What did the previous generations do with such small HP-rated engines to get the same work done as we do today? (Nevermind that some engines (like a big cam cummins) can be bumped from 350 to over 500 or engine swaps, etc.)?
Was it that transmission gearing was designed per the task but, as a result, tractors were limited to a narrow range of function (e.g. can get 1/2 million pounds of logs on a double down off the hills but can't get over 30 mph on the road, etc.)?
Thanks.

Yes. That is one thing but you also have to remember in the old days, men were men and women stay in the kitchen. Then the 70s came along and they started burning their bra's that led to globe warming and companies lowering wages. Union membership fail behind and Jimmy Carter was elected. That whole Iran thing. Then Reagan he tried to get the horse power up but was shot coming out of a secret meeting with the big three engine makers. And Clinton, give me a break. He was interested in the sleeper sections of the cab. I believe you have all seen the Monica bunks in the 94 Volvo's. Hillary of course really screwed it up talking about how horsepower was just a right wing plot to attack women's health. Bush tried to help but he was distracted by 911 and having to find those Weapons of Mass destruction. I believe they were put on a truck that had been purchased with a lease from Trans Am and just are driving around in the dessert somewhere. Obama took over and promised a new deal so now we have Horsepower and are all pulling together to make America the country that it was always meant to be. A country where we can all speak Spanish.

I dont think the OP was expecting this answer. Good show.

So, they pushed their trucks ... uphill both ways ... in four feet of snow ... and they liked it?
I have to say that I have been tempted by some of those older rigs and simply wonder what I would be losing going mechanical and lower rated HP. I drive some day cabs now that are below 300HP (P & D types), but they are late model, i.e. electronic, and when I am freighted I just can't giddy-up the hills and I am burning more fuel.
Any word on the fuel efficiency of mechanical engines? I am familiar with the light truck 12V 5.9 cummins being very good and very responsive to tuning. Are larger mech. tractor engines similar? I am afraid I would throw black smoke (-$!) everywhere without those elec. govs baby-sitting my every move. -
Things changed alot over the decades. As far as I'm concerned time plays a crucial role. Everybody wants their stuff the day before they order it. When I started out 350 Hp was alot of power. I ran a 290 Cat. If you are not running atleast 450 today you are out of the game. I pulled 68000lbs with a 290 second and third gear wasn't an issue at the time. It took me the whole day to deliver a load and nobody cared, as long as the job got done. Fuel consumption wasn't an issue, fuel was cheap and the rates was good. There where less trucks on the road so competition wasn't that feirce. Hail the good old days.

I see what you are saying, Worthken, it boils down to competition and the changed nature of the business. Thank you.

WOW I guess me and my little wore out, can't get it done, under powered 425 better retire....
Jake The Bullhauler, pullingtrucker and dairyman Thank this. -
Just remember one thing. I'm not saying there isn't a place for old trucks in todays economy, it's just a bit more difficult to get the work for them. I'm still running a 1971, 335 Small camm Cummins. The problem is have to pick the loads carefully, I dont send it further than a 100miles from base. It's possible but not easy.
-
Haha. Wait another 10 years and tell it to the guys that tell you their 800Hp motor seems a bit small, and they cant understand how anybody in their right mind could pull a load with 425 Donkeys.
