The Kubota GB155 is equipped with a rear PTO and a Category 0 three-point hitch, allowing it to use many small implements.
Rear PTO

| PTO shaft size | 1.375″ |
3-Point Hitch

With position control, the operator can set and maintain the implement working height precisely, which is very important for:
-
Uniform tillage depth
-
Clean and level mowing
-
Accurate ridging or bed forming
Dimensions & Tires
The GB155 shares the same 50-inch wheelbase as other GB models, but its slightly higher weight and different rear tire size give it good stability and traction.
| Item | Details |
|---|---|
| Wheelbase | 50 in (127 cm) |
| Weight | 1,246 lbs (565 kg) |
| Front tire | 5.00-12 |
| Rear tire | 8-18 |
This compact size is ideal for:
-
Narrow orchard rows
-
Greenhouses and small vegetable plots
-
Tight farmyards and garden paths
At the same time, its weight and 4WD system give the GB155 good grip on soft or wet ground, while still keeping soil compaction moderate.
Electrical System
| Item | Details |
|---|---|
| Ground | Electric (negative ground) |
| Battery | 12-volt battery |
The standard 12V electrical system powers the starter motor, lights and instruments, and replacement batteries are easy to find in most countries.
