Don't know how cold you folks get it your area but I had one installed when buying my 2006 DK 35 when new. It works but in the really cold, (-20c to -30c range), I add 2 magnetic heaters, one on each half of my engine sump. Also added a battery blanket heater. Maybe overkill but my Kioti starts quite quickly in our winters. I may add another heater to my hyd filter.

Here is a situation that users of engine heaters do not think of.
Most newer tractors have a glow plug controller which decides how long the GP's will heat based upon engine temp.
Because the GP controller is usually using engine block temp to decide how much GP time to allow, with a warm block it can not heat the GP's long enough in very cold conditions.
The GP's are on only briefly if at all, because the block is warm.
In spite of the warm block, the engine is inhaling -30 outside air and it does not light off like it should.
Often there is a trick known to dealer's mechanics who have to move tractors around the lot for snow removal. For Kubota's, by putting the shuttle in forward instead of neutral and turning the key to start, you effect an manual application of the GP's where you control how long to heat.
When I use this trick the engine fires before it even turns over.
The latest Kubota's, when the dealer has installed a block heater, have a change made in the programming of the GP controller. The controller senses outdoor air temp and the GP's stay on the proper length of time rather than block coolant temp logic which does not give enough GP time.
Owner's who think they are saving money installing their own block heater are unaware of the programming change to the GP controller which should be done to have the tractor starting its best.
