Good replacement part but needed to make a slight adjustment
High quality replacement part, but I needed to make a small adjustment for proper fit. The cause of the small interference could have been the result of earlier repairs made to the mower deck, however. The small adjustment to the arm break was within the skill of anyone willing to tackle failed parts on a mower deck, however.

I removed deck from mower so I could see moving parts better. I am 73 years young and laying on my side looking under mower was not my cup of tea. Upon removing deck I could see the results of 11 years of use. The parts were worn extremely bad and were hanging up and not releasing the Idler pulley when moving lever to dis-engage blades. I should have ordered 2 Arm assembly Pad Brake but as it turned out one was not worn as bad as the other. The job was relatively easy. Just removed spring tensions first and laid them aside. Proceeded to remove nuts from carriage bolt. Put new parts on and put deck under mower. Mowed an acre of grass and had no problems. On a parts quality note..... The Arm Assembly pad Brake has a bolt on end that has a roller on it that is used in the disengage mode. On the original arm it was a thru bolt with nylon lock nut. The new one is just pressed in and I think it should have been spot welded where it come thru the arm. Only time will tell. If a person has a welding machine I would highly recommend putting a spot weld there as that bolt at times will have a lot of pressure on it as it slides around the edge of idler arm.

The most difficult job was, taking the mower off the tractor. That took the most time. The spring that holds the arm in place is the most intimidating part of the repair. I used a long screw drive to bring it around to position. My suggestion with any repair, is do not take apart until you have new parts, or make a detailed drawing. It's easy to mix up the way things go
back together.
