Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

there has been much discussion lately about torque and horsepower.

at work today i did a little research on my lunch break.

the results of my little comparison are somewhat surprising.

the numbers for the tecumseh engines were obtained from microfiche cards that are 2 years old. they are the most up to date ones with that info on them we have .they have newer cardss but the horsepower and torque curves arent on them.

the numbers for the briggs engines was taken from a 2004 engine sales brochure.

every dealer will have these cards and papers but the numbers are somewhat difficult to find.

i was however determined to deliver the facts so here i am.

tecumseh first.and please note that not all engine numbers are available at this time to me.

hmsk 70    11.3   lbs  of torque  at   2450 rpm

hmsk 80    12.75  lbs of torque at   3000 rpm

hmsk 100  15.5   lbs of torque at   2600 rpm

hmsk 110   15.75  lbs of torque at   2500 rpm

ohsk 120  17.5  lbs of torque at   2550 rpm

 briggs next... all ohv intek snow engines.

9 horse  14   lbs torque  at    2500  rpm

10 horse  14.25   lbs torque at   2500 rpm

11 horse 18 .5   lbs torque at   2400 rpm.

i know this dosent include many of the engines we have but those numbers werent available to me .

but im not done just yet and i will keep posting about my finds.

i was led to beleive that the briggs had a lot more torque than the tecumseh but except fot the 11 horse one the tecumseh  engines are pretty good on paper..

tecumseh has been working quite hard on a v twin L head snow engine that was supposed to be very emission friendly.not sure what has been going on with it but update schools are in a month so ill know more then.

please note that the tecumseh numbers were taken from a microfiche card and it was not in the best of condition .

i beleive the numbers are accurate but not positive.

later chris 

specifications subject to change without notice...ha ha

 

Snowshoveler, thank you for your research. i see you have done a lot of number crunching.                  18 degrees

Last year I posted a press release from a trade publication about the V-Twin Tecumseh. It was suposed to have been installed on a number of Husquarvana blowers and a shop in  Mass. had them asdvertised. When I called they claimed they were sold out .

I question whether or not those machines ever existed or if the engine was ever released. T-Man said if he heard anything he would let us know.
