The basic L3800 is a very good platform. The serviceability is easy for routine maintenance. The conventional raised hood allows easy access to oil levels, fluid checks and air filter. Front loader controls are easy to reach, but a bucket level indicator should be a standard item as the long nose of the tractor does not allow for easy bucket level assessment. The engine always starts easily, especially in winter if the block heater is used. Steering is light. Gear range selection in the hydro-static transmission(low, med, high) is very notchy, sometimes frustratingly so. However the 3 settings are great as opposed to the JD I looked at with only 2 transmission ranges.
Changing from 4WD to 2WD often requires lifting the front end off the ground with the loader and switching the lever. Otherwise it will not go into 2WD.
I would recommend that Kubota go to a larger hydraulic pump on this unit, especially with the backhoe attachment.
The engine is very quiet which is nice. The hydro-stat is not. The transmission is very "whiny". Be sure and wear proper hearing protection when operating.
Speaking of attachments, the backhoe is "average". The controls are rather sloppy and not near as precise as they should be. It is assembled/built in the USA. That being said, after 30 minutes of use I developed a hydraulic hose leak. After 1 hour of use, the bolts that hold the hand levers on the hydraulic splitters fell out, rendering the hoe useless. Not good assembly. I call it the "Monday/Friday" hoe. The tractor itself is well made and sturdy and gets high marks. Fuel efficiency is excellent. Remarkable in fact.
