Hello I bought a 03 Grasshopper with 25 kholer and 61" deck with 1100hrs on it 4 years ago. I take care of about 10 acres with it. My 5acre yard gets mowed when needed and the other 5 acres of wooded area gets a trim about 4-5 times a year. OK, the mower now has 1550hrs on it. Should I think about selling it and get one with less hrs or just repair my when needed. It runs good and mows great! I over-servise it. I change the oil&filter about ever 60 hrs and the hydro-oil every year. I can't afford a new one. What would you do? THANKS!!!!!
