Engine guys - chime in!

[Hooked_on_HP]

Look up up the specs for the snow blower you have and see what the minimum hp requirement is. You have to have at least this much hp for the blower to run acceptably. This rating is also usually pto hp not engine. When ever you modify a small engine to get more power you greatly shorter the life span and the dependability.

Don't forget to factor in the inherent inefficiency of hydraulic drive. Calculate the HP developed by the hydraulic motor, not just the engine driving the pump. That will be an eye-opener.

Thanks - I had 13.5 HP from my PTO which the blower worked fine.

I agree, I should assume a 80% efficency since I am using hydraulics.

I will look at a specs for a 60" blower for HP input required

I think you are a little high on calculation. I would bet you will be getting close to 15 hydraulic HP at best.

Your Kubota TLB has a diesel engine, which has more inherent torque than a gas Kawi would. To increase torque on a gas engine would be to increase compression ratio , larger pistons, longer stroke, but not more RPM as in your application. Possibly a higher lift camshaft, but not more duration. All of this costs money, a larger motor or slower gearing would be easier.
