Protein Pushups! 
Too cool!
. My curiosity has been piqued!
I see what appears to be the front of a possibly big Cat engine, very likely diesel, harmonic ballancer, belts, coolant pump, air intake maybe? Or turbo gas encabulator (stock, not retro).
Whats up with that?
Looks like a C12 engine
Thats a doozy! Im not sure which ones are in the trucks I do stuff on, but they are incredibly powerful. Massive torque.
Yes sir, in a 99 peterbilt. Temp sensor was broken. Snapped a pic to make sure i got the correct one.
Ha! Glad I’m not the only one. It looks like the belt on the clutch assembly is slightly out of alignment or the wrong size.
This is a new development!
How you like it?
What? The mower?
. I thought so?
I remember we spoke of it, but didn’t know it was in use.
This one belongs to one of my peeps. It’s a big Gravely, this thing is a beast! That is 5ft tall Johnson grass. I went really slow because I thought there maybe baby fawns in there. 
It’s awesome but honestly my cub cadet is easier to use. You constantly have to hold this one back. NO brakes. You are either going foward or backwards, don’t let go of the handles! 6 six hours of that was enough todaying for today.
