I've had my 1025r about a year now and at the beginning of the summer season I added a mulching kit to my 54" mowing deck. Once I added the mulching parts I noticed that after I make a pass there are often blades of grass that go uncut in the middle of the pass. At first I thought it was just me so I adjusted height, mowing speeds, RPM, and everything else I could think of to be sure I wasn't doing anything wrong. Yesterday I mowed and I was again frustrated by grass seemingly in the middle of the deck not being cut. I was mowing at walking speed at the recommended PTO RPM and still had issues.
When I installed the mulching kit I didn't notice any problems putting anything on. I had the issue most run into with the bolts not biting into the plastic shroud very well but I was able to work around it and get everything tight.
Does anyone have any ideas on what could be going on or what I should check?
