855D John Deere diesel gator, these fit perfectly, I did have to cut a tiny bit of the stud off the top of each of these, the stud is a little bit too long and will touch the valve cover above the glow plugs if it isn't cut down. Simple to match it right up to the old ones and cut to match. Took less than a minute. Went from very long crank times after sitting overnight to starting right up every time.

I installed these in my John Deere gator and I had to trim the height which wasn't a problem it has beand over a month and they work well.

As you can see in the picture, the stud is longer than the factory glow plugs. This caused a short because the top of the glow plug touched the valve cover blowing a fuse. I used a Dremmel tool to cut off about 3/16".

Tractor was not starting. John Deere.. would smoke and not turn over. These fixed the problem!

This was a great replacement for my John Deere gator that was not starting when cold. Watch YouTube and the was able to replace with easy. The Gator starts right up, great product so fa!

Fit and worked.

No taper on end of threads to seat properly and treads on top are to long to allow valve cover to fit Do not buy if your wanting to use on John Deer X750 garden tractor

Very happy with this product and shipping was on time..👍🏻

Bought three for the price of one at John Deere and they worked amazingly well to date. Very pleased

Work awesome

Garbage.never even got a year out of them.had to buy a set from the John deere dealer.original ones from dealer are $100 each but worth it in the long run

One of those did a short circuit and blow my main fuse.

Glow plugs worked for 5mins… don’t waste your money…
