This mower is about 8 years old and was given to me by my son with only
about 15 hours on it.It was lent out to his neighbor and brought is back saying
it would not start. He took it away to get repaired and was quoted about 250.00 to repair it. It had a bent crankshaft so he b rout it home and told me
about it. I asked what he was going to do with the old one,he said throw it in the trash he had all ready ordered a new one. He said i could have it if i wanted it. So that is where i got it from.
So the first part of November i started trying to convert it to propane.
If i can down laod a picture i will do it.

I appreciate the comments.
Yes, 8 years ago i put in a new crank shaft lower seal and gaskets, didn't even pull the
piston out being it was so new.
I have it running on propane and was surprised haw quiet and easy to start.
So far it has started at 25 degrees and at 72, but it takes 3 pulls every time.
I am not bright enough to get a picture and hear it running.
We have about 25 knock out roses and i trimmed them all and lined up all the debrea
on the lawn and mulched it, then put the beggar on and picked it all up.

It is hard to say at this time, but yesterday i had a pound can with four ounces in so i put
it back on and timed it and it run at govern speed for 40 min. No load. I had to leave
and pulled it off, but is was almost gone. This mower is only 6.75 HP.
When i get better information i will post it..................Gordon

This the rear view. I used a KN regulator i got from the internet for about 50.00
I can us this type because the motor runs at a govern speed. (no idle)

The shinny regulator is a KN made by century a lot of company's make them. The fuel adl elbow on top of the regulator, i ordered from company also, some people make them.
The light green regulator sitting on the horizontal bar is a SE-7 high pressure regulator,
that brings high of the propane supply down to about 1/2 lb.
Three items i bought from a Co. and other items i picked up local.

Thanks Gordon,

So now, the shiny one, does that require engine vacuum to draw the propane or is the flow constant when the valve is opened? In other words, if the engine is off, does flow stop?

The way i understand it, it needs vacuum to keep flow. When the engine is stopped
i shut the valve by the cylinder,i don't want to be around if there is a (big bang)
This regulator does have a primer button to hold in a second or so prior to starting, lots
of times it will start with out it.

You asked how much propane it would burn, so today i weighed a bottle
before i had a job to do, then weighed it after i was finished. It only run 9 1/2 min
on two ounces of propane.
What i was doing was mulching deep leaves in a ditch in front of the house,
because when the wind blows hear, they seem to end up on the porch.
I wont be using it any more until spring...............Gordon

Hi all, I have run the LP Toro for a full year with out a problem and about 25 to 30
hours. Changed the oil this winter and was as clean as when is was put in.
I run the mower out of fuel on purpose and weighed the bottle. It weighed 417
grams and that is what an empty bottle is supposed to weigh.A new bottle weighs
about 800 grams, about 80% full.
This year i had 7 wheelbarrow full of rose bush vines after trimming and chopped
them up with the mower, some stems 1/2" . I did stall it out 2 times,but seems like
it does have some good torque and started first pull when it stalled out.
So all in all i would say i wouldn't change anything.
The mower was run more this year than i normally do because i was trying to lose
weight and i would mow until i got tired then finished with the ZTR. Gordon
