I have a JDX 485 and a JD 425 I have snow blowers for both and leaf carts if you look around you can Find some good deals I have $5600 in everything I’ve had both for many years neither one has ever been in the shop but you have to do your maintenance both the machines the decks and snowblowers...
The batteries are solar panels the wind turbines all come from China when you got a White House and his family that’s in cahoots with China that’s what you get
I wouldn’t mess around with the Welch plugs , I have a few all snowmobile’s with them carbs very hard to fine parts I would say clean it the best you can and go from there
you need more weight on your lawnmower do you know how much your tractor weighs? I have a 425 John Deere weighs about 1200 pounds with everything and I have no problem
My JD did the some, put a carb kit and set the governor, use it to blow snow it was 3 above zero yesterday, and don’t need to run the nipko on it for a half hour like before
