Hydraulic Leaks Around 5 Green on the Surround and in Rough on 6

Our green surround mower had a fitting come loose on the wheel drive around 5 green. The operator went 2 full laps around the rough part of the green when he spotted the leak. In his haste to get back to the shop, he drove across the rough in front of 6 green which will cause further damage. We went out and wiped down the area from any excess fluid.

I would spray it down but a majority of the area is hilly and would become a slippery mess and issue for anyone playing that hole. The area is pretty obvious so just be aware and refrain from stepping on the areas if at all possible. Hopefully, it appears a majority of the oil was up in the leaf layer of the plant and did not come into contact with the crown near the ground. We will have some yellow areas appear in the next couple of days and no doubt some of the turf will die. We will evaluate any turf loss and replace what we need to replace as soon as possible. In the mean time, please watch your step in the left walk off area of the green and around the back and right side as well. I will go out and circle this area as ground under repair. Please take a drop away from the damaged area so we do not transfer any excess oil to the putting green. We wiped the lines down to remove the excess oil but some of the leaves are still very saturated.  I apologize for this inconvenience. We will discuss with the staff regarding what to do when there is another leak which we hope is a long time from now.

Back of 5 green. The arrows are pointing at the oil line. 3-4" wide or so.

Walk off area to the left side of 5 green. Area is a little wider at the bottom. The mower pulled up and backed up doubling the size of the area.
