For small 21-22" push mowers, you know these trans engage cables: Well, the wire inside keeps breaking. I have the tension right, otherwise the trans would be always spinning the wheels if it were too tight. If I'm using my 22" toro, it'll break about once every 6 weeks and is a PITA. They are only $15 on ebay but I already have a swagging tool and some wire and crimps so I just replace the wire for like $0.50. But it still always breaks because the wire is too thin. I keep spare wire and Throttle Stop Nuts with me for emergency repair until I can crimp a new one later but they always break at the worst time. You can only fit I think it's 1/16th wire in the stock tubes. I grease the wire before I put it in so it acts as a rust barrier but they break with no rust. So is there possibly a mower or piece of equipment that uses a larger version of this? something I can fit like 1/8-1/4" wire in? I was looking at "flexible metal tubing" but it's basically too limp, like faucet supply lines. The tubing has to be stiff enough so that if you push the tubing, it'll take the slack out of the wire - that's how you adjust the trans cable when the belt starts to stretch a little or the trans or wheel gears start to ware down a little and you need to put more tension on the wire to compensate. The tubing is stiff enough to push the wire outward in a sort of "C" and thus when you pull the wire, the tubing doesn't pull with the wire - it keeps it taught and therefore gives more tension if you set the tubing this way for more tension... Also it needs that connector at the bottom that pops into a hole in the mower deck and then you squeeze it with pliers to pop it back out the hole to remove the tubing/cable. And then on the handlebar where you adjust the tube, this tubing would be too thick to put into the stock bracket but I could improvise on that end too basically with a clamp - undo the clamp and slide in/out to reduce/increase slack in the tubing. And then I'll just drill a slightly larger hole in the deck to accommodate the larger pop-in connector.
