- 01 Kubota B21TLB, 2010 Ferris 52" ZTR, Cub Cadet 1811, Gravely Super8
here are the specs for the B20 from a 2002 posting by Muhammad
D950-A-T 56.6 cu.in water-cooled 3-cylinder diesel
20HP gross
17.5HP net
13.5 PTO HP @ 2600RPM
5.3 gal fuel tank
4.2 qts cooling system
4.1 qts engine oil
30.6 qts hydrostatic fluid
0-11.31mph traveling speed
Standard:
3-range hydro
540 rear PTO
Position control (3PH lift of 1279lbs @ LP; 1014lbs 24" behind)
Fixed mount loader
NO mid PTO
R4 tires (R1 rears optional)
Dual hydraulic pumps (one for FEL, one for BH ---12.7GPM total)
4WD
Power steering
Steel plate slanted nose
Dimensions:
106.7" length
53.7" width
60.4" wheelbase
9.2' turning circle (w/o brake)
TL420 Loader Standard (B20 TL)
56" buckets (square or round back... round is heavy duty) w/6.35 cu. ft. capacity
86.3" max lift height
66.1" clearance w/bucket dumped
23.8" reach @ max height
40 degree max dump angle
56.9" reach on ground
40 degree max rollback angle
6.5" digging depth
926lbs max lift capacity
1543lbs breakout force
Lift to full height in 2.9 seconds
Rollback in 2.3 seconds
Standard self leveling
BT750 Backhoe Optional (B20 TLB/BT650 standard)
92.9" digging depth
(750 stands for 7.5' digging depth... 650 stands for 6.5'. Later models all came with the 750.)
2) Yes.
3) I'm thinking good/great deal @ $10k ... nice @ $11k. I wouldn't pay $12.5k since it has 900 hours. @ 500 or less, maybe, if it were mint.
4) Not really. To match the B20's performance, you're going to need to go for a B2710, or more realistically, the replacement B21 TL, which will run you about $19k new without backhoe.
5) B21. They're very similar. B21 got the new style flat deck, new dash, standard FOPS (falling object protective structure, aka reinforced canopy), and a few other minor changes. I'm not positive but I think the B20 may have dry shoe brakes, while the B21 has wet disc. That was one of the feature updates when the new B-series machines came out for '96.
Basically, the B20 is in Kubota's compact TLB class... they're extremely hard working machines, durable, great performers... not as versatile without a quick-attach FEL, and the heavy weight in addition to that fact makes them less suitable for lawn mowing than conventional tractors.

Before I would even consider the purchase, whether from a dealer or individual, I would like a little history of its prior life. If it came from a rental yard at any point in its life, I wouldn't walk, but run from the deal! Unless you are handy with a wrench, and can disassemble and repair one, that may have had hundreds or more different of operators over its life.
They are a little workhorse, and if it has been maintained it maybe a good deal if the price is right. For comparison, type it tractorhouse.com, and find similar ones and prices. They sell tractors of all brands throughout the US on consignment.

Thanks to the both of you for the stats and info. I checked out tractorhouse.com and found a 94 b20. The one I'm looking at is in better shape, comes with a Laurin cab and a Linkletter tandem trailer. I don't believe the tractor was part of a rental fleet. Thanks Again.
