Run time of push lawn mower?

[slybunda]

These push mowers that have 125cc or 140cc motors and 0.8L fuel tanks how long is the run time on a full tank?

All depends on engine speed, load or no load. If you must know, gas it up and find out for your particular mower.

1.5 hours IME

It depends on the load. If you are mowing tall heavy grass you might only get 45 minutes out of a tank. On the other hand, if you let the mower just sit and run without mowing anything, it could take several hours to run through a tank.

I have a 160 that will do ~1.5-2.5hrs. medium load. Maybe even more than that as I just filled up 1/2 tank and easily mowed 1.25hrs.
I would guess that they are normally designed to operate for that period of time.

I have a toro SR4 with the 159cc engine. In normal mowing conditions I easily get 1.5-2 hours. In thick/tall/damp I get 1hr15mins max.

Agree with the above, although I'd figure on ~1hr runtime worst case. The fuel tanks and CC's for these particular OPE engines are getting smaller and smaller.

The fuel tank on the 180cc Briggs "professional series" on my 10yr/old snapper 21" mower is annoyingly small, but my typical usage is maybe 45min tops at part throttle (machine actually has an adjustable one) , so I can get 2 uses between fillups.

45 to 90 minutes. This depends on many factors. How tall or wet your grass is. What type of grass you have.

I have a mower with a Honda 161 cc engine. It has only one speed. In medium mowing it runs about 1 1/2 hours on a full tank.

I have a .9 qt. tank on the Chonda. My lawn is 45 min when I mow it all by push mower. I can do this twice on my push mower per tank. My lawn has long and short grasses. So average I guess.
