Hi all, I have a Cub 7205 tractor with loader and backhoe. It has been working great until today. It will not start, I suspect due to the colder weather here in New England. It cranks and puffs white smoke but will not fire off. I suspect the glow plugs. I changed the fuel filter also. I know diesels are hard to start in colder weather, it has been in the mid 30's as of late. The tractor has a Mitsubishi S3L engine in it. My question is, has anyone experienced this? I am planning on changing the glow plugs, does anyone have a suggestion for the type or part number to use? I want to use a name brand like NGK or Bosch and avoid the 'off brands' available from China on Amazon. Appreciate any other tips or suggestions. Thx, Tom
