curious... if 'AZ dirt IS as hard as concrete' why do you need a grade blade ,let alone a land plane ?
Farmer cross the road just used beam and chains to keep his 1,000' driveway beautiful, for decades.
Also what's a BH bucket coupler ?
A "bucket coupler" is for backhoe bucket changing only.
Kubota BH bucket couplers are made, and sold by Kubota, for their
dedicated TLB, and mini-ex machines only!
B26 TLB, L47 TLB, and M62 TLB, are Kubota's only currently manufactured
dedicated TLB's.
These machines also have loaders that are not removable (unless you bring your big tool box).
This coupler is exactly the same coupler that Kubota uses on most of their mini-ex machines!
Thus: most mini-ex buckets will fit any Kubota machine with the standard Kubota mini-ex coupler.
The coupler allows bucket connection while seated at the
dedicated TLB backhoe station, and then curling the bucket to catch a set of bucket "ears".
No fiddling with pins or hammers to connect.
Only needing dismount to push in a small locking pin.
On the L47, & M62 I think the cost of this coupler alone, is approaching $900.
A really slick system!
Most all the big and small excavators use a similar system,...all brands.
I have the coupler on my L48 TLB.
I can change between either of my two buckets, and/or my root ripper (I love it) in about 3 minutes, with absolutely zero physical effort (did I mention that I am an old guy?)
