hi everyone and welcome to the DigNDoze channel in this video we are going to look at the five mini
excavators representing the 2-ton weight class bobcat e20 takeuchi tb 16 caterpillar 301.7cr
kubota u17-hgs and yanmar vio17-a before we go any further please take a moment to subscribe to
our channel if you haven't done it yet and hit the bell icon to get notifications on
our latest videos okay so these machines are next to the smallest available on the market
they're not as compact as 1-ton minis to be able to pass through the standard building doors and
easily maneuver inside the buildings but of course it all depends on how tight is the space around
as you can see this cat machine fits perfectly down the hallway at least these 2-ton minis would
pass through the most of the backyard gates what also helps in using these minis in tight spaces
is the zero tail swing feature which is available on most of these machines with that you'll have
a peace of mind not gonna be worrying hitting an object or causing the damage at the back of
machines cap the only exception here is takeuchi tb216 which has a so-called conventional tail
the cabin of this machine overhangs for 16.7 inches beyond the tracks when turned 90 degrees to
the direction of travel keep in mind that some of these minis may have optional counterweights such
as this cat 301.7cr it gives a little extension to the cabin's tail and turns it from a zero tail
swing machine into a compact radius let's now take a closer look at their specs all of these machines
are equipped with retractable undercarriages the smallest is yanmar vio 17 with its 37.4
inch wide undercarriage takeuchi tb 216 is 38.6 inches and all the others are 39 inch wide again
tracks retracted as mentioned before all of them would easily pass to a standard 42-inch fan skate
to enter a backyard but for interior work with limited space for maneuvering smaller models would
be a better choice especially if there is a need to drive a mini through a standard 36 inch doorway
let's look at what these guys are powered by all of these machines have three cylinder diesel
engines with displacements ranging from 43.9 to 69 cubic inches caterpillar 301.7cr has a
little more powerful motor in this group it has an output of 21 horsepower at 2400 rpms bobcat
takeuchi and yanmar have engines with similar outputs ranging from 13.9 to 15.2 hp it has to
be mentioned that the engine's horsepower does not necessarily tie in with machine spray coat forces
bobcat e20 has the lowest horsepower among these minis 13.9 hp but his bucket breakout force
is almost 4700 pounds which is 4 to 12 hundred pounds more than of its competitors the maximum
travel speed of this minis is pretty much the same from 2.6 to 2.7 miles per hour
speaking of the auxiliary hydraulics the leaders here are takeuchi and cat takeuchi tb216 develops
3046 psi system operating pressure and 8.9 gallon per minute of flow for caterpillar
these parameters are 3553 psi and 8.7 gallon per minute respectively this gives these machines
a little advantage when using high capacity attachments like breakers augers or compactors
now how deep can they dig bobcat e20 digs the deepest compared to its competitors his digging
depth is eight foot five kubota caterpillar and takeuchi dig pretty much to the same depth seven
foot seven to seven foot ten the yanmar's digging depth is a few inches less seven foot three
anyway all of these minis will be most productive at the depth about a foot less than their maximum
to sum up all that has been said and to let you see the full picture
we are providing this comparison chart for free the link is available in description below
it can be quite useful and also contains data for few other minis not covered in this video
