I've got the L3000's big brother; the L4300. Same idea, a good basic gear tractor with an 8x2 transmission. The transmission is its biggest limitation. CP1969's remarks about the reverse speeds is dead-on. The Reverse gear ratio is between 2nd and 3rd in the base 4 spd. transmission....so in High range, the speed is between 6th and 7th like CP sez. Even Low range reverse is too fast for some applications. I thought Kubota goofed on this, but I find that similar reverse ratios are used on Ford 8x2 transmissions; so it must be a tradition or something.
If you're going to shift between low range and high range, you should come to a complete halt. Some have damaged their transmissions by shifting between ranges on the fly. The manual cautions against shifting the base 4-speed transmission on the fly; but that doesn't seem to cause any trouble and the shifts are pretty easy if you only go up or down a gear at a time. I think the L3000 will have similar restrictions.
Basically the L4300 seems to be a simple, rugged, straightforward tractor. I'm sure the L3000 is the same. If you value honest simplicity above troublesome sophistication, you'll probably like the L3000. If it has to sit for awhile, there's less for the mice to chew up.
They're light for their power so you might want to have the rears filled. $9K seems about right.
