[nikilom]

I buy this lawn mower deck second hand , but i don't know what model is it and from what garden tractor is it .
I have need of help with that . If somebody know what model is it or from what tractor is , please let me say.
I think it have these are missing , because nowhere have a brand , model , stamp and etc.
Just only have sticker and write "40 do not step " and with small letter 3531 .

Take off the blade and take a pic of it. Also look closely at the belt for any numbers.
