Just a couple thoughts...
When I ordered my
B2910 a couple years ago I ordered the 60" bucket. Before taking delivery I decided to change to the 54" bucket. I have often thought to myself that I am glad I went with the smaller bucket.
Rear tires with R4s are 53 inches wide about a foot off the ground, so even with the narrower bucket I don't have a problem following behind when I scrape a path with the loader.
The narrower bucket fits between trees better and lets the tractor go where a 60" might not.
The 54" bucket seems a little more heavy duty than the 60."
When working with damp/soggy earth I have at times found my loader working real hard lifting a full bucket. Might not have lifted the 60" when full.
For light stuff, the larger bucket is obviously better if the added width does not get in the way otherwise.
I guess what I am trying to say is that over the last couple years I have been surprised now and then by thoughts telling me that downgrading to the 54" bucket was the best thing I could have done for my particular circumstances.
Another thing is the R4 tires. I am not sure what I would do there. With all the rain this summer, I ended up putting my chains back on after having them off just a couple weeks. The problem with R4s and our clay soil is that the F4s quickly fill with mud and turn into slicks. Even with ladder chains it can be a problem moving around on a slight slope.
I will try to attach a photo of slick tires if I can did one up. Still, I like the R4s. If I were to buy a
B3030 next year I don't know if I would buy R1s or R4s. R1s are a little narrower, so would give more clearance for chains if you were to use chains. I have wished for R1s when slipping and sliding on wet surfaces, but somehow have always managed to get out, with a little help from the loader (and backhoe when it was on).
While I don't know how much difference there may be, it has been suggested by others here at TBN that R1 tires may be more likely to puncture through the side walls.
PS...those are R4 tires on the tractor in the picture... /forums/images/graemlins/shocked.gif
