Hi. Welcome.
When I warm up in winter I run the PTO while running at 1500 to 1800 rpm. This moves the trans/hydro fluid warming it up. Operate the attachments to move the cold fluid into the warm.

In my area block heaters are not necessary. In your area it would be a good idea unless the tractor is stored in a warm barn.
If you use synthetic oil a dipstick heater should not be necessary. I maybe wrong on this as I rarely have to start in temps below 10 deg.

Welcome to the forum. 
I'm going to move this thread over to the Kubota section in case anyone else finds the information useful.

Even though Kubotas generally star good in cold weather;a block heater will help in the northern climates.My tractor sits outdoors and only gets plugged in if it's 20 degrees F. or colder.Not always needed but helps warm the oil and easier on the motor.

Welcome!
Don't waste your time/money on a dipstick heater.
Block heater is the way to go.
Also 10W30 diesel oil,or 5W40 diesel synthetic oil would be prudent.
If you have a hydrostat,Super UDT2 hydraulic fluid will flow much better at low temps.
Don't forget to treat your fuel before it gets cold.
Good Luck!

My dealer install block heaters on all L series and larger as part of the package.
5W-40 synthetic engine oil. Neighbor blew a crank seal on his NH using 15W-40. NH said they would replace one under warranty but don't do it again. They didn't specifically say that in their manual but through experience they rely on their dealers to spread the word.
Use Super UDT2 oil in the transmission. It has much better cold flow characteristics than plain UDT or any of the multi-purpose tractor hydraulic oils you find for lower prices.
I loved my L3710 but when I retired and moved up here permanently I traded for a cab. Wish I could have kept the smaller tractor - handy sometimes but couldn't justify it. Zero problems in 9 years, most reliable tractor I ever had.
