Look at this

[Brian902]

you realize it's a lawn mower and not a ground conditioner. ha ha ha

they should look like that a 150 hrs.

what are you cutting?

if your blades are that bad, the deck is probably close to toast too.

looks like they were sand blasted.

Looks like you should have been keep an eye on your blades. Those things should have been replaced a long time ago and if I were you and those blades only have 52 hrs I'd fined a different manufacturer.

We pull blades off daily and replace them with fresh ones. Some times cutting heavy Bahia grass at times we pull them off mid day and put on fresh ones.

It normally takes 5 minutes or so to change blades on a Tigercat Scag.

We change when grass starts to string. We joke and say when out Scags start cutting like Kubota's with new blades it is time to change them.
