I am talking occasional work on my 2.5 acres.
This is a fine homeowner's tractor for one to four / five acres. Tractors in this employ average 60 to 80 engine hours of use per year. The tractor will last indefinitely in your situation with conscientious greasing and fluid changes.
My main reason for a replacement tractor is the FEL. Is the FEL strong enough to lift and move dirt?
The 'real world' FEL lift capacity is 661 pounds.
Few would move more than 80 pounds of dirt in a wheelbarrow, for comparison. So, theoretically, the bucket will move 8-1/4 wheelbarrow loads per trip.
To lift 661 pounds you need counterbalance mounted on the Three Point Hitch. A Box Blade is often used for counterbalance and is one of the primary implements used for smoothing dirt and dragging dirt short distances, about thirty feet max. Counterbalance of 400 pounds should be about right, the weight of a heavy
54" to 60" wide Box Blade.
Turf tires are fine on a tractor of this weight, unless you will be doing considerable mowing of saplings or unless your ground has lots of thorns or sharp edged rocks. If this is your first tractor, turfs will make this light tractor feel an increment of two more stable than other tires. The Kubota
B2920 has 4-WD, which is more important for traction than tire type, unless you have a long mud season, when R1 ag tires
might prove just a mite better than turf tires. (The bar tread on light tractor R1/ag tires does not protrude far.) Most Florida soil is sand based and not very challenging to Three Point Hitch implements WHEN MOIST.
My concern is spending a bunch of money, to me, for something that may work me more than the tractor.
The tractor has power steering. The implements are light, proportional to the tractor weight and, with experience, easy to mount.
If your height is over 5'10" or you wear a size 10 shoe or larger, be sure to sit on the Kubota. The operating station on Kubota B's are none too commodious.
This tractor is probably free of Tier IV emission controls, which many here consider burdensome. A plus factor.
