My garden tractor is 26hp, my scut tlb is 22.5, how come?

I'm sure this has been answered before, but just gimme the quick&dirty. Why scuts are powered less than some garden tractors?

Torquey diesel with a legit horsepower spec, versus an overly optimisitic rating of a gasser?

Do you have the torque numbers on each?

At what RPM is the HP rated? It’s easier to achieve higher HP numbers on engines set up for higher RPM, but they’re going to lack grunt.

That’s just life. There is no reason!

Naw, I don't have all those specs. But I'm just saying, my gt is fairly capable. Before my gc1710, that's what I was using. I have a snow/dozer blade for it, I would plow with it and level off rooted dirt (I had pigs). And obviously mow with it, actually that's what I still mow with. It muscles through all the slopes and ruts I have here, mostly. It did all that ok enough on its own with 2wd and locking differential. In 4wd, it would be a little beast.

There is tho! Just gotta find it, I heard about dmt on joe rogan's podcast.

My 1963 Cub Cadet 123 was the same, and likely moved more dirt in its life than 95% of compact utility tractors sold today, it just did it much more slowly.

Part of your answer probably is in the torque difference. A diesel generally has a lot of torque but is relatively low in horsepower. You'll also see differences in the gearing. The wheel size may be a factor as well, I'm no sure on that one.

I've got the charts for my Sears get and my Bolens/Iseki. The Sears is rated at 3600 rpm for 20 hp and 33.3 ft. lb of torque at 2400 rpm. It displaces 624 cc.
The Bolens is rated at 2600 rpm for 14.5 hp and 30 ft. lb of torque at 1800 rpm. It displaces 776 cc.
That said, the Bolens weighs about 600 lb more. That and the gearing is where you feel the difference. I've pushed snow and plowed the garden with both. The Bolens seems to do those tasks more easily, I believe weight is the difference. Mowing is pretty much the same, but my grass doesn't get real long between cuttings.
The Bolens also uses less fuel, even though it has a higher displacement.
I think HP sells mowers. Weight and torque make a tractor.

Your MF has a 68 cubic inch engine.
Your Craftsman has a 45 cubic inch engine.

Horsepower is horsepower no matter what produces it. Your bigger engine has 50% more displacement and probably much longer connecting rods. Longer connecting rods means longer levers. Longer levers mean more torque.

While both engines will make similar horsepower, the bigger displacement one with longer levers will be able to produce more torque and keep it in that torque range longer than the smaller displacement engine.
