A 20 hp kohler engine, is it underpowered for a 52" deck?
For me,yes. For a homeowner....probably not. I'm sure others will have a different opinion though.
Good clarification TLS. I was thinking ztr.
Well . . .according to my old realiable arithmetic methods, that would be slightly more hp per inch than a 25hp/60", which I have found to have plenty power under expectable operating conditions (and running a mulch kit). Of course, the 25hp I'm referring to is a Kawi v-twin which would have slightly more torque, thus balancing out the difference, making them relatively equal. My opinion, 20hp/52" is not underpowered.
Yeah, but 20 horse Kohlers were always dogs. Very low on torque.
You can never have too much power. I love the 23hp on my 48" walkbehind. I use a sulky most of the tome so actually it's a ride behind. I have bogged it sown a couople times grinding leaves. wo I don't think it's too much. I would rather hae extra hp than not enough.
I did have a 20 hp on a 52" walkbehind for a while and it did OK but it did bog some and it was slow. I mean you had to go slow to get a good cut.
The trend lately is to more hp. so why not.
I have a John Deere 17HP 1cylinder walk behind 54" deck.
Plenty of power.
2" less, and extra cylinder, and 3 more horses?
If that Kohler is running right, you might be OVER powered.
Overpowered? Whats that?
Your 17hp One Holer Kawi is 27.5 ft/lbs torque.
A 20hp Kohler twin is 32.6 ft/lbs torque.
Two TOTALLY different engine classes.
Neither would EVER be considered OVERPOWERED on a 52" deck.
Minimum I'd want on a 52" is 25hp Kohler or a 23hp Kawi. both in the 41 ft/lb. range.
not for a walkbehind, for a rider
