I have a Deere L-100 series lawnmower that the mower deck has rusted out. Trying to decide on a new deck for $700 or buy a new mower. I live near Galveston bay so the deck takes a beating due to the salt on the grass. Mower has close to 700 hours and gets used on about 1 acre per week and an additional 2 1/2 acres once or twice a month. Our grass grows 9 months of the year. That’s probably pushing the operations limit for a 42” cut consumer grade mower. Options: Replace deck. Cheapest option. Motor and chassis is good. Not sure about the durability of the transmission. It would suck if I bought a new deck and the tranny went out. Replace with same style mower. Big drawback in my mind is stamped deck which is the weak point on the Deere. Might get a wider cutting width on this option. Replace with heavy duty mower. Much more expensive upfront cost but might payoff in longer life and better performance. Thoughts?
