Propane ZTR'S

I just ordered a propane heater for my JD Gator and it got me thinking.

How safe do you feel sitting in between two tanks of propane on a mower?

I know those are incendiary rounds, but still the tanks are awfully exposed on those mowers and anything could cause a spark.

That was an awesome "experiment" with the propane tank, however, an operator is sitting between regular gasoline tanks also with the same type of concern / exposure to being burned if something untoward happens !!

Is it different then people that operate forklifts? I used to run a forklift and one time another operator backed right into something and punctured the tank. No explosion though. Cool video anyway. I agree with Lifetree dont think its anymore dangerous then the gas tanks.

Myhtbusters tested this and found without the introduction of an external spark at the same time, the tanks will not explode when merely punctured.

They are safe and clean. Proven for years and years in other settings.

Just for fun (in thought only), would you rather grill with a gasoline tank under your hot grill?

Ha, good way to think about it.

What if you slide down a hill (very common with ZTRS, especially if they have huge cylinders mounted up high raising the center of gravity) and there is a brick wall at the bottom? Smash, spark, BOOM.

What if while the neighbor is calibrating the laser sight on his hunting rifle a bird craps in his eye causing him to jerk the weapon up resulting in the laser blinding the cockpit crew of a passing airline which then crashes into you while on your propane ZTR? Smash, spark, BOOM!

Just as possible as your “what if” and almost as probable. Seems to me that higher COG would make it more likely to rollover, not slide.

Also seems to me there are other much more probable things to worry about than these low probability, multiple failure, highly unlikely scenarios.

You think it's unlikely to slide down a hill on a ZTR?

At least if gasoline starts to spill out I can see it and I know when it getting close to a heat source. I know it's the vapor that ignites, but still.

No, I'm saying that the impact being great enough to puncture one or both tanks, and the spark occurring at just the right time and in close enough proximity to ignite the gas are, at best, highly unlikely, especially given average ZTR mowing speeds. It takes a pretty good hit and in just the right way to cause a breach in a propane tank. Hence, it's highly improbable to the point of being almost unrealistic.

I'm also saying that generally, a higher COG increases the possibility of a rollover. If you're seeing gas spilling out of your tanks, you're on too steep of an incline, and/or your tank caps are loose. Time to rethink how you operate your machine.
