Thanks for the feedback.
I think you're right -- I should get a bigger trailer. I'm going to consider the 6'x12' from Lowes but I'll also see what's available used when the time comes.
I don't think I need a true backhoe and would rather opt for the lower center of gravity with the 425. My mountain land makes safety an bigger factor re tipping. One of my longer term investment properties is also 4 hilly acres. Plus I like the idea of moving the mini-hoe easily from one digging spot to the next without setting up a stationary backhoe.
The thumb is a cheap addition to the mini-hoe that will grapple stuff. So I'm thinking I'll see how far that takes me before I consider a grapple bucket.
I'm not planning to do massive clearing, so I think the smaller machine will work well for me. You can buy a number of attachments for the $6k difference between the 425 and the 1430.
You mentioned doubts about the fine cut heads. Do you think the hinged blade of the brush cutter does a good enough job on grass?
I have a 425 the grapple bucket, rock bucket, LM bucket and mini-hoe with thumb... in addition to a few more attachments.
IMO, I'd get the grapple bucket and not get the rock bucket. The grapple bucket is the same bucket size as the rock bucket, and has longer teeth on it. It will dig even better than the rock bucket, and there is simply no substitute for the grapple when it comes to moving brush and debris. It's even great for clearing the old garden plants out of the garden in fall.
Because the minihoe is on about a 4 ft boom, it will not lift nearly as much weight as the grapple bucket due to the different leverage -- in addition to the fact that it can't be used to scoop up debris like the bucket.
As far as mowing with the rough cut mower, it does a decent job on long grass like fescue, if you keep the blades sharp. However, because it spins much slower than the finish mower, it wil not do nearly as good a job when it comes to fine, lawn-type grasses like bluegrass.
