Hello all. Currently on break here at work...on snow duty tonight.

where I work we have nice 700 series 4x4 JDs to remove snow.

I want your opinion...whenever I turn off a tractor I idle it down. Whenever I start a tractor I start it at idle and let her warm up a little before going full throttle.(with the exception of my tired onan, I start that one at 1/4 throttle) Isn’t this common practice?

Everyone at work starts and stops these things at full throttle, even in 0 degree weather with a cold engine and it bugs the heck out of me. Am I crazy? :/

Back to work, looking forward to the opinions tomorrow

I always idle them down to shut off and start them either idling or about 1/4 throttle like you. That also drives me crazy when people do that! I tell them it is like a car, you don't give it gas when you shut it off. lol.

Wait a minute! Brandan, are you telling me I’m not supposed to floor my truck every time I shut it off!? Haha.

Yep. Idle down for a few seconds before shutting down.
I startvmy x320 with the idle down and at least half choke.

I agree with Brandan and Chaser on startups at idle-1/4 throttle and idling down before shut off. Full throttle starts when cold just Has to be causing unnecessary wear on cylinders and other parts before adequate lubrication has time to reach critical parts. I've always started all my vehicles at low r.p.m.s even in our warmer climate and I'm sure it's even more important in your colder areas of the country, especially in winter.

Are the X700's gas engined or Diesel? If they are gas engined, they are running the risk of bending the pushrods for the valves.

Ours have gas engines at my work. I didn’t know that about the push rods, is that specific to the engines in those tractors?

It's pretty much common on any small overhead valve gas engines, the older flat head engines were more forgiving for this.
