Worked on Cub Cadet 2135
Direct replacement for a Cub Cadet HDS 2130. PTO wouldn't engage and this got it back to mowing.

Works as promised
I used this on a Cub Cadet LT1045 which is actually made by MTD like many other brands of mowers so this relay should work on just about any of them. The relay controls the blade PTO by receiving the open/closed signal from the user operated PTO switch and then sending current to operate the PTO. I am sure this thing has many more applications than riding lawnmowers.
