cbburrows,
Hi. First of all, check my profile and you'll see that I have quite a bit of Woods stuff for my
B2910. I like their quality, but they don't come cheap. Depending upon your uses, you might be able to get similar implements from other mfg.'s for considerable savings.
I'll preface what I'm going to say with you will be happy with the tractor and implements you've selected. I'm just going to try to make you happier and lighten your wallet just a little more.
As far as the backhoe, since you're going with a MMM, the Woods subframe will cause interference, hence your choice for a 3 pt. mount. First of all, if you're putting a 3 pt. hoe on this rig, go with the Kubota hoe. If you look in the owner's manual for the tractor, it says a subframe is necessary. I would be concerned about warranty issues with any other 3 pt. hoe. Second, go with the 4690 hoe...i.e. the 7 1/2 foot hoe. (If you do go with Woods, go for the 7500 instead, you'll appreciate the extra reach. Period.)\
For my Woods 7500 subframe backhoe I've got an 8" bucket and a 16" bucket. I wouldn't go much larger than 18" in hard rocky soil like we've got. If you have sandy soil, you probably could, but my 16" looks just about the right size on the hoe. If you can spring for 2, depending upon your soil conditions, I would recommend either 8"-12" for one and 16" or 18" for the other, depending upon your requirements and soil conditions. If you can only afford one, I would suggest the 16".
For the post hole digger...I have the 1160. If you have hard, rocky ground, you want as much weight as possible on the PHD. I would've opted for the 1190 but I knew the 1160 was overkill for my purposes. The gear case a.k.a. "pumpkin" is quite a bit bigger on the 1160 than the 1130 and it holds quite a bit more lubricant, so that's why I opted for the 1160. I got the 12" auger. They have double and single flight. I have a double flight, but probably should've gotten the single flight. The single flight is better if you have a lot of rocks (I do) and the double flight is better for sandy soils (or so I'm told). That said, mine works great in rocky hard clay. The cutting tips on the end need to be in good shape.
If you'll be doing a lot of snow removal, I strongly recommend a 3 pt. snowblower. I have the SS60 and it works very well. I need the loader on during the winter to clear parts of our drive that couldn't be done with a rear or front mount blower. I like having the loader available. You can try using just a loader/rear blade combo and add the snowblower later, if you find the need.
Speaking of rear blades...I have the HBL-72 model. The RB blades are nice, but do not offset easily (you have to remove the blade a manually shift it over, requiring some tools and elbow grease). I've only used mine a couple times, but each time I made use of the offset feature. I wouldn't want a rear blade that did not easily offset. The HBL is heavy and expensive, but I think it's well worth it, especially if you're not going to get that snowblower...put the extra into the blade. There are other mfg's of rear blades that are cheaper than Woods and have an easy offset adjustment.
I also have a Woods boxblade but haven't used it yet. I loaned my tractor to my cousin and he's used it, and made favorable comments about the HB60. I liked the idea of the floating rear gate, although I'm not sure why. I just figured it would be better to have it than not.
I have the 60" loader on my tractor and wouldn't want the smaller loader. When back-grading with the loader having a couple extra inches of width is nice. I'm not sure what you could put in the bucket to exceed the lift capacity. I also like the wider bucket when using it as "wheel barrow" a stuffing branches and brush in it. The extra 6" is nice.
Are you broke yet? Seriously, you'll be thrilled with your tractor on so many levels it isn't funny. If you've had trouble justifying the expense, believe me, you won't have any doubt in your mind once it's proven itself a couple times. And it won't take long.
Good Luck in your decisions.
