I want to know everything there is to know about it..My dealer has never sold one..I don't understand why..Anyone actually used one I'd love to hear from you..Thanks
I'm pretty sure the Scag engineers took power requirements into account when they chose the 25 hp Kubota engine.
If you're worried about the 25 hp diesel rating as compared to the 35 hp gas engine rating, don't be. This engine operates at lower rpms than the gas engine. It will have more torque than the gas engines. I think the engine in my tractor is rated at 27.5 PTO hp. If I were to replace it with one of those 35 hp V-twin gas engines, I guarantee it would be a downgrade in performance. It powers a 6-foot mower with ease and I don't even run it at full power. IIRC, when I bought the mower, the salesman said my tractor could power a 7-foot mower if I wanted--and that's at 27.5 hp.
Yeah, I know but it really isn't a good comparison.
If horsepower alone were a good way to compare engines, it would make no difference if you put a 300 hp L-10 Cummins or a 300 hp small block Chevy in an 80,000 lb tractor trailer.
The first generation Dodge Cummins pickups proved it, as well. I think the first generation Dodge Cummins was only rated at 140 or maybe 175 horsepower but would easily outpull gas engines with much higher hp ratings.
I don't even know what Bahia grass is, but I'll bet the diesel cuts it better than a gas engine. It has more torque and that's what does the work.
As far as weights go, the 61" diesel model is shown as being 95 lbs heavier than the gas model. For some strange reason, the 72" model is shown as being 255 lbs heavier than a gas model. That doesn't make any sense, because it's the same engine for both models.
I got those numbers from the owner's manual that is downloadable on the Scag website.
As to whether the additional weight hurts or helps, I can't answer. It's over the drive wheels which I would think would help unless you get in really soft stuff.
