The tool did not come with a shoulder strap. It is too heavy to operate for over just a few minutes without a strap. The strap is an optional purchase. I use a 9.0 AHr battery which works very well. Machine ran well.

We have 3 battery operated Milwaukee tools, a high torque 1/2" impact, a four inch angle grinder, and a portable vacuum. We are farmers, so we use these tools sporadically, so battery life is not an issue, as we have three 5.0 batteries. Will the 5.0's run virtually any battery operated Milwaukee tool? Battery life is typically not an issue with us, as we don't use them in a professional manner.

BEST ANSWER: I have used a 5.0 battery to operate my 2825-20st string trimmer. I prefer to use the 9.0 battery, but only because it allows me to trim more area without changing the battery. I have several M18 tools and in my experience they all run equally well with the 5.0 battery as with the 9.0 or 12.0 batteries, the only difference being the run time before battery change.
any idea if the trimmer head can be replaced with one for brush cutting?
