Ok, here’s the little project I’ve been working on for the last couple weeks. I’ve been wanting to make a small lawn mower/trimmer with an O&R and I had a nice 133 military engine that needed to find a home. Thanks to Terry@Just O&R, he was able to hook me up with the perfect vintage mower - it was exactly what I was hoping for. This one is a 14” Sensation, perfect size and design style for the O&R.
It’s not 100% done yet but I couldn’t put off getting some photos posted. I’m still working on the actual trimmer concept and plan to go with more of a weed eater head set up instead of a mower blade. I plan to use the starter cup off a vintage Pioneer chainsaw and drill three holes so I can pass through some pre-cut Trimmer lines with end-stops. I’ll figure out a good way to secure the cup to the spindle shaft. I also added a stop button to the back plate similar to a few other O&R tools I have. I’m also finalizing a short throttle cable, doesn’t really need one but thought it might be nice. After a lot of hunting I ended up finding a cast aluminum boat chair pedestal that made the perfect adapter plate to mount the engine to the mower. I also had to swap out the normal Type 133 mount with one that has a couple more inches in height. This was needed to get the right clearance for the gas tank. Just a note, the early style Drillgine gas tanks don’t mount to the newer style engines and I had to make a couple slight mods to the casting on the case to get all the clearances to fit right.
Here is the before and after...
