Yesterday after work my youngest son and I took the loader off my Mahindra 8560 and hooked to the round baler to get it ready for this year. Knew that we had a hydraulic hose leaking (short hose that hooks to the door lift). We got everything out of the way so we could see the hoses, could not see where it was leaking, started the tractor, moved the hyd. lever and found out very quickly which hose was leaking. We removed the hose and today after work I went to the hydraulic shop and got a new one made. After supper I went out to put the hose back on but the tractor was gone. Got to the shop and found tractor and baler had rolled down a hill and into the side of a storage trailer. Bent the brush guard around, crushed the grill, hood ruined and broke the windshield . When I bought it 4 1/2 years ago had to insure it for full coverage for the financing. I have paid it off but kept the insurance I will find out tomorrow how good the insurance is. I am sure no one else on here has ever forgot to set the parking brake. By the way the tractor sat there for over 24 hours before it started to roll because I saw it in front of my shop when I got in from the Hydraulic shop.
