I had my new BX2370 delivered Thursday, and have been unable to use it until today (Saturday) due to work. Unfortunately, the owners manual did not come with it, and the place I purchased the tractor from mailed it to me Friday...I was hoping to get it today but did not. Anyhow, I have a FEL and 54" MMM. I wanted to try the MMM today on my yard, but could not get the mid mount to engage. The tractor has two sets of levers, one set engages the PTO, the other set allows me to select either rear PTO, rear and mid PTO and the last setting which is rear PTO only. I had the tractor in N, about 1/3 idle, I moved the set of levers from the off to the on position for the PTO (no problem doing this), then I tried to move the selector from rear PTO only to the last setting which would be for the MMM only. When I did this it "grinds" immediately, so I stopped the second I heard this. Am I doing something wrong, or what exactly should I do? Since I don't have the owners manual I want to make sure I am following the correct procedure. Unfortunately my dealer is only open until 12 on Saturday, so they are closed.
