Vertical vs Horizontal mounted engines

I am purchasing a new Exmark 50" Triton deck with the 27HP Kohler. What, if any are the differences / advantages to choosing between a vertical or horizontal mounted engines? Thanks for any comments!!!

Do a search, there was a thread almost identical to this one with just about the same question. Found it... http://www.lawnsite.com/showthread.p...cal+horizontal

Wow! First time that I read that thread. Lots of conjecture.

Anyone for reviving the thread in question?

Well I'll bite on this one. I think horz engines last longer because of the piston direction. you'll find that the new OHV horz are in a slant position because studies have found that there is less piston wear in a piston traveling in a slant or horz postion. Think about it? havnt you seen those 5-11hp horz engines just keep running and running. now do the math a vert engine has the effect of gravity always pulling the piston assy towards the cylinders bottom and putting more pressure on the cylinder bore than a horz engine does. I gotta go take a nap now!

I didn't read that entire thread, but it seems to me the mule drives would rob power. I had a SuperZ with the gearbox and it was a disaster. My new one (26 hp liquid-cooled Kawasaki) is a vertical mount and it has been flawless.

IMO, Horizontal means more moving parts in a drive system and more parts to wear out and tear up.

Comparison between horizontal[walker] and vertical[greatdane] horizontal-all the ground debris either sticks toair inlet screen or goes through to clog cyl.fins. Choclate bar wrappers tissues etc- block screen & cause overheating. Temperture guage fitted. I have many s/hand engines 600-1300hrs all overheated vertical -after speaking to operater [he does all the general maintenance] Machine mows more grass than i do mostly.Screen does not block with either dry or damp/wet grass or papers . 2500hrs ok
