I'm looking for a compact tractor for a hobby farm. It seems to me that the B7610 will dig the holes for the fencing and clear the brush for the pasture, but it seems like it may be pushed to the limit when it comes to moving round bales, especially with the loader.
I would say "no". That tractor is to small for any size of round bale. If you had a 30-33 hp compact you could, if you went slow and watched it and it wasn't to small of a frame.
A small tractor like this should use a rear spear to move bales, and have counter weight such as a loader on the front.
As the other posters say, be careful, carry it low and slow.
Really you should be looking to the L3130 size to do this on a regular basis. The 3130 could carry on the 723 loader with proper counter weight on back.
Are you sure about the weight? From what some people around East Texas have told me some of the round bales can weigh as much as 1,000 pounds. I imagine the amount of moisture in the hay could affect the weight quite a bit.

I agree with the above posts the B7610 would most likely have a very difficult time moving an average round bale. btolle is right about the weight. The round bales that I cut on my East Texas pasture (coastal bermuda) weigh on average between 1,000-1,500 pounds. I own a L3130 w/513 loader and the loader (with box blade counterweight) can handle a round bale but it is almost dragging the ground. Most of the time I transport round bales with my 3pt and 3pt bale spear with some counterweight in the bucket of my FEL.
I'd go HST L3830 with the 7 series loader, for the extra couple of thousand dollars. It would be an excellent choice for a small farm tractor. Get the quick-attach loader and you'll have easy use of a front bail spear (3pt is good too). For the amount of tractor you get, the price seems very reasonable (when comparing to $$ of B series). Kubota makes it easy for you to move up to the next one /forums/images/graemlins/tongue.gif I believe you could pick a B7610 right off the ground in the loader. You want the weight and the strength of a Grand L for farm work...IMO. I think it will last longer with the demands you appear to be asking of it.
Start thinking about the cost jump now and it won't seem too bad in a couple of weeks /forums/images/graemlins/grin.gif
Round bales have a huge span in weight, a soft core 4x4 weighs about 400 lb. A high density 6x6 may weigh 2000 lb if a bit wet. A 5x6 silage bale weighs even more!
