No worries man, glad to help. A lot of us here were in the same shoes, wondering what to get, what not to get, etc.
From what you're describing here, you're bound to have some people on TBN telling you that you should be shopping for a tractor larger than a scut. I wouldn't necessarily agree with that statement, but I will say that you should keep in mind that this is a little tractor, more geared towards landscaping and stuff like that, compared to more serious excavation. Not that you can't use it for that, it's just that it would be slower going.
But in any case, whether you end up using the massey scut for running long trenches and digging up for septic, or rent equipment or hire out for that...you DO need a tractor/loader/backhoe just for keeping up your property. I mean, if you're the one keeping up (as opposed to hiring a landscaping service), you need one is what I'm saying.
Your bucket doesn't look to be quick attach, no. You're gonna have to convert it to quick attach if you're intent on getting a grapple, unless you get an add-a-grapple thumb. Add-a-grapple uses your existing bucket, and just adds a thumb on top that clamps down. The thumb itself is quick attach, so easy to remove when you're not needing it. They work ok for what they are, but a real grapple is way more efficient. If you got a lot of woods to clear out, and will be doing it regularly, a real grapple is probably the way to go.
