Hello everyone, here in Michigan it is getting colder as I'm sure a lot of you experienced and the snow is immanent. That being said I bought my 2240 earlier this year when it was warm and I am new to the compact and diesel tractor world. This past week it was below freezing (around 25 degrees) and when I start it up it doesn't run smooth, it pops and acts like it wants to idle fast and I haven't touched the throttle and it is set to idle. I am curious if this is caused by the tractor being a 3 cylinder or if there is something going wrong (injectors, injection pump). Now after it warms up for 10 minutes it quits popping and runs like a champ. I should say that the tractor only has 2100 hours on it and the lift pump was replaced once. The tractor doesn't have any glow plugs but it does have a coolant heater and that helps but I put it in a new pole barn without power otherwise I would use it. The tractor isn't hard to start I am just concerned about what is causing the popping action. Thanks and I hope everyone has a good winter.
