I don't recommend that toggle switch idea as stated. A self-resetting push button switch won't catch on clothes or on brush. Plus - the first time a simple toggle is inadvertently left in the ON position, best case scenario is that either/all of the following will burn out: switch/wire/glow plugs. Worst case; fire. If a toggle is used at all, it must be the spring return type that goes to OFF as soon as you let go. Then it must be rated to switch no less than 30 amps, as must the wire connecting it to the glow plugs. The safest way is to replace the cheap OE keyswitch with a decent aftermarket cold start switch and a heavy duty Ford-type relay. The OE wire is sufficient to connect the keyswitch HEAT post with the relay. Then use 10AWG copper primary wire to connect the relay to the battery and to the glow plug buss bar.
The older Y80/Y85 series engines are notorious hard starters, regardless of conditions. I've had 3 of them. And the colder it gets, the harder they resist starting. Worst case scenario is one with no compression release. That was the case with my Y485. There wasn't enough room between the valve cover and the fuel tank, so the manufacturer simply sold the tractor with no compression release. So I used the above described glow plug relay PLUS a heavy duty starter relay PLUS an oil pan heater. Started first time/every time after that.
