Damn if she isn’t. Four horse B&S. Not a pause.
Did you edit the OP to make it less cryptic?
All righty then.
Purple monkey dishwasher!
“Signs the OP is a Trump supporter, for $1000, Alex”
Some sort of all wheel drive vehicle with a 4 horsepower Briggs and Stratton engine
A mower with such.
Is it a mulcher, or do you have to crawl behind it naked gobbling up the clippings?
Have to? Philistine!
Excuse me, I speak jive.
"You kids bought that all-wheel-drive Huskie brand riding lawnmower. So now go mow the back yard.
And damned if my daughter isn’t mowing it. I can hear that four horsepower Briggs and Stratton engine running without pause."
Yeah, that totally clears up the OP. Not.
“Damn if she isn’t.” Damn if she isn’t what? And who is she?
Did you know that you don’t have to pay by the letter to post here? It’s entirely possible to be coherent.
This. Precisely this. I’m amazed. Next thing you know they’ll be using that fancy vacuum they bought.
Stood in its box for months.
Pear pimples for hairy fishnuts!
Cut me some slack, Jack! Chump don’ want no help, chump don’t GET da help!
mmm
That’s very clever! 
So, his kids haven’t bought a cute husky dog, then?
Further attempts at clarifying the OP.
Title:
I believe “Now” should be “Mow”. Which immediately makes this next part much clearer.
Now we get to this.
Perhaps “such” should be “mulch” or “mulcher” because autocorrect. If we apply this correction, we again have a sentence that makes sense. Just my theory, which I submit now for peer review.
I installed a 2-stroke engine in a Malamute and the damn thing bit me!
I’m not cleaning up that back yard either…
Alternately:
"You kids bought that huskie, an almost wolflike dog. Now go put her in the back yard.
Damned if that dog didn’t eat two of my horses for breakfast and two more for supper. Without even pausing between them."
Awww! Opus!
