Kawasaki fx801v or fx850v or Kohler ch740v

in practical usage how much difference is there between the fx801v (25.5 hp 44.6 ft lbs torque) and the fx850 (27hp 44.6 ft lbs torque) also the Kohler ch740v (25 hp 39.2 ft lbs torque) on a 60 inch deck mower My thoughts are not much difference between the 2 kawasaki's as torque figures are the same. I am looking at the exmark laser z FX801 $10500 (after 26% equine savings) OTD Scag Cheetah FX850 $10700 OTD and Kubota Z725 Kohler CH740V $9500 (after $1000 Rebate) OTD Any thought or advise would be great

If you want power the Kawasakis will have more. Both the 801 and 850 are the same block which is 852cc. The Kohler is 725cc. There is no replacement for displacement.

Agreed - much more power out of the kawi's

Kohler builds a reliable motor that needs no valve adjustments though

There is a difference between the 801 and the 850, regardless of the specs posted on their site. HP is what keeps the blades spinning at high rpms. Torque is what gets them there from a stop. Both Kawi's are way ahead of the Kohler for performance.

There is a difference however I said they have the same block which is true. Probably the only difference is the jetting of the carbs and how far the throttle valves are allowed to open.

My comment was directed to the OP's OP, but yes, the difference is in how far the throttle plate opens, and that's all.

There have been many guys here who bough the JD 910 with the 22 HP (now 20.5 hp) engine who switched to a throttle plate from the 920 and gained 3HP in doing so. Only cost them about $50 and a bit of their time. Lot cheaper than paying JD for the power.

Not likely - the cheetah is faster, with heavier blades and spindles. I expect they will feel similar

Also have to remember the mower and its hydro's play a large roll in how much power is needed. For example my 160Z has a kohler 25 command. Nothing ever slows it down. I have never heard it bog under any conditions for any reason. Our 160Z has small 10cc hydro gear hydros. Most peoples quest for speeeeeeeeeeeed even though 99% of people never cut at full stick makes manufacturers install huge power hungry hydros.

My property is 300 ft wide by 1900 ft long so I can use some speed while cutting when I looked at toro they have nothing in the 5000/6000 series between 25 and 34 hp I wonder why such a large gap in HP
