I was wondering if anyone has issues with the exhaust from a powertorque tilt-a-cut burning a strip on the lawn when edging at lower speeds? Has anyone modified the exhaust to come out above the edger deck? I had some edging to do that required me to work at low speed, and some sections of the lawn have to be edged from on it, not a path etc. I love the machine, however I can't seem to use it fast enough for a burnt strip not to develop over the few days afterwards.
20% of the fuel used in a 2 stroke goes out the exhaust unburnt. So the exhaust is shooting fuel vapour onto your grass, and leaving a trail of dead grass. We all know what happens when you spill petrol onto grass. The machine is lingering too long in any given spot and bombarding the grass with this unburnt petrol.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
Hi John, I'm not sure how the muffler is situated but if it is a standard Powertorque muffler shooting straight down , I have in a couple of cases, hammered the muffler outlet flat and drilled a series of holes in the front of the muffler discharge section, works no problem, maybe 7/8 holes about 8mm in diameter
Thanks for the tip Bruce, but all my victas are run at full throttle. This is the second tilt-a-cut I�ve had, and it does the same thing (burns the lawn if not moved fast enough) Perhaps I should look at my technique. I thought it may be worth mentioning the poppet valve on the carb is set to C.
I decided to take to a spare muffler with a dremel - I cut the front side of the muffler away, then folded the shorter part of the outlet 90 degrees so it shoots out the back of the machine. Seems to work ok, just gotta get all the carbon out of the exhaust and test it out a few times to see how it goes. Seemed to work nicely on a test run. I might need to rivet a plate on the bottom or do something to keep exhaust off the powdercoat
I must admit I've never thought of it too much but the normal Victa 2 stroke mower runs the same type of set up with the exhaust firing straight down onto the lawn surface, but the only thing that would save the lawn is that the blade disc is rotating and gets in the way of the downward direction of the exhaust creating turbulence thus saving the lawn, but with the edger there's nothing underneath to obstruct the exhaust gases thus the lawn takes the full brunt of it.
Just wondering why this hasn't been brought up before ?
Cheers, BB.
I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
I was wondering the same myself Bonnar_Bloke, I thought it must have been a problem before. I�m thinking about doing the same to one of my powertorque mowers as sometimes my wintergreen seems a little dry in the few days after mowing. I�m sure it�s the poor soil it�s growing in, but it can�t hurt to try and see if there is any noticeable difference. Not scientific I know, but I�m sure 2 stroke exhaust isn�t great for fresh cut grass
No doubt the blade disc normally forms part of the exhaust expelling process. You will notice any smoke shoots straight out the side of the catcher! Not so here. They should have developed an exhaust that shoots sideways. Maybe bring back the rocket muffler!
