Need a Rotor, that holds the blade assem. Model 7880 30 or 7830 KD, hard to read, Thirty "cut. Where can I get this item?

Thanks

Any other numbers on that thing? Is it a rear engine rider? I'm familiar with some of those, but the numbers you've given don't come up anywhere. 30" rear engine Lawn Chiefs I see have a trhee digit number followed by a letter. Like 320j, 320k. Anything like that on the thing?

Carry the old parts to the local mtd dealer. They will either have or be able to order the part.
