Thanks, I guess I should mention how it is being driven. If you look at the top of the last picture there is a piece of 2x2 tubing that makes a "t" at the end of the boom arm. This plugs into receiver hitch on a 3 point trailer mover I made for the back of my tractor and allows me to adjust the offset from the side of the tractor. I use the lift arms to raise and lower the boom so that it follows the slope. I don't have a picture handy at the moment.
The chain is to limit the angle of operation to 10 degrees off horizontal, I have a turnbuckel to add for a finer degree of control. The reason to limit the angle is because this push mower, like most residential grade mowers, uses a splash lubricated engine, that if tilted too far, will starve the bearings of oil. Briggs recommends a maximum angle of continuious operation of 15 degrees. I allowed 5 degree of sidehill of the tractor. Next time I use it I will put an protractor on the hood an see if I am even getting 5 degree of angle.
I have not had anything shot towards me, that is why I have the side discharge chute closed. In the really thick grass it would be nice to have a discharge so I plan to build a chute that hooks to the rear bagger chute and discharges the clippings to the rear and slightly away from the water to keep them out the pond. This was just a test run to see how well the idea worked so I could change the bracket if needed before I paint everything.
Esshup, that is a great idea about the break away. A pivot point with a shear pin to hold it closed it one possibility. I have a few different length shocks that I may try by using just one to see how it reacts. It has done pretty good without them though.
