I have a new 2018 2025R that I have had about a month. As I am using it around a lot of trees and brush I thought that a guard kit for the warning lights would be a wise investment. Picked up the BLV10400 Guard kit at my Deere dealer today. Looked like a very simple install. Remove cap screws, place warning light assembly inside the guard, line up holes and replace the cap screws just removed. Except the cap screws are short. One turn of the wrench and they were out. Only about 4 threads on the tip of the screw are engaging the treaded insert in the light. Put thickness of the guard between light and threaded insert and maybe 2 threads are going to engage. Cap screws are 65MM long and need to be at least 70MM and preferably 75MM long. No screws are included and instructions state cap screws removed are to be reused. Have to wonder if there was a shortage of longer bolts on the assembly line and they used what they had on hand. Going to call dealer in the morning and see what they say. Probably end up going to Fastenal to get longer cap screws.

That's a bummer. I have a 1025R and IIRC, I did reuse the original bolts, but into a different threaded insert on 1 of them, due to lining up the holes in the guard. Putting the guard on also left the upper hole of the guard and light in the open enough that I used a couple screws I had to fasten them together, since it kinda left that portion 'floppin in the breeze' a bit.

You might want to consider mounting the lights inside the ROPS for even more protection.

Checked my tractors number and it is over 200 units to the side of the change to longer bolts. Guessing that the ROPS was a earlier unit hence the shorter bolts. Dealer said he has longer bolts and to stop in next time by and he will give me 4. Thanks everyone!

You have to sign-on to JD Parts, enter the part number and then it will give you the price, stock-status at your dealer and if available, the technical specifications. Anyone can create a sign-on.
