I think those weights for the 72 inch deck are wrong. (Imagine that) I have other data that shows the weight for both standard and 7-iron decks as 448 pounds. That sounds more correct.

Welcome to TBN brienk. Glad to have you here. Thanks for the info. I cannot locate my reference data, but I certainly do remember back then somehow knowing the weight was 500 pounds. Very heavy deck to deal with, but also very sturdy. My 60 inch version has given zero problems for 17 years.

On another note, I noticed while I was changing the blades that there is a bracket of some sort behind the blade area. Is there a roller assembly that fits in there? I bought it used a year ago. I'll go out and take a picture tonight if it helps.

Yes, there is a rear roller assembly similar to the one on the front.

Yeah, that part is missing on my deck. I'll look into it and see what it costs.

Do not know what parts may already be on your deck, but quick check of two main parts shows this. Two rollers are required.

I've priced out the parts I need to refresh all of the worn parts on my deck (front casters need repalcement, gauge wheels need it, anti scalp rollers are worn, splines on the shaft are worn).... $$$$$$$$$

Oh, I need a belt too.
