We have Tractor Supply stores here. They have a plate with all different size bolt patterns. You can try until you find the corret one.
If that's not availiable, go to a hardware store and try the different size nits until you find the correct one.
I am about to change the hydraulic oil in my 2815 hst. The operators manual says there are five drain plugs but they picture only three. Anybody know the location of the other two?
If this has been covered already, I was unable to locate the post.
Thanks,
