Hello, I have a grasshopper that keeps breaking the tension spring we've replaced it 4 times now in the past week, the tension bar has alot of room to wiggle up and down moves side to side fine but i feel it has to mush room to move up and down, would that cause me to go thru all these springs, all springs were brand new! Im not sure the year or model number but the deck is in front with a mulching attachment on. Could this cause it? or something else? Please help!
