I have cold started my kubota B7510 a couple of times this winter, below 20 f. and it sounds like it is horrendous on the engine. I am running 20w15 vs. the spec. 10w30 because the dealer said it is better, given the diesel additives these days.. The question is this: I have moderate technical skills; is installing a block heater difficult?

The block heater for the B7510 screws into a plug in the engine block just like the B2410/2710/2910 as they all use the same parts kit. You will need a good sized 17mm allen wrench and probably a cheater bar or pipe to get the plug loose then out. Sears sells the allen wrench. You will also need some teflon tape to seal the threads when you screw the heater in. Installation should take less than 10 minutes once you get the plug out.

I had my dealer install mine. 65 bucks parts and labor. I tinker a bit, but didn't want the mess. Also, I can drive my tractor to my dealer. (Handy)
20 bucks for the labor was worth it.

Like MadReferee says, it's a quick and easy job. And your engine will appreciate it.

Save your money. 20 weight will not flow freely into the tight tolerances of a modern engin like yours, at cold temperatures. I use 5W 30 in cold Michigan winters. I think your dealer is misguided in his thinking. Read your manual and trust the factory before you trust a dealer. Have him show the service bulleten from Kubota. I'll bet he can't produce one. 20W30 means when the oil is cold it 20 wieght. No wonder it sounds bad when you crank it over. In the hot summer 20W30 might make sense but even then I would not deviate from the manuafacturers specification. In the summer your oil is only 15 weight and too thin to protect surfaces that are machined to such tight tolerances. Is your tractor still under warranty?

20w15 sounds bogus. Did you mean 20w50? Or 15w40?

The correct Kubota part number for the screw in kit is 70000-73274 and it fits B1700/2100/2400 and B2410/2710/2910/7800 and B7610/7500/7510 and B2630/3030.
Part number 70000-74128 is for the B7300hsd/7400hsd/7410dt and will require two thermostat gaskets and a parts kit. I believe that this kit is an inline kit.

I installed an aftermarket heater in my B7800 that is threaded but is smaller than the threaded hole in the block, so I used a standard threaded pipe bushing to adapt. The install was easy and the heater works great.
