Short answer: Yes, you can track.
BUT, this type of Dobsonian comes at a price. Have a look at this link to the Go-To dobs that are available:

Don't be too concerned with needing to track. It isn't critical, only convenient.
Scope that don't track you would allow the object you are viewing to drift across the field of view, and every now and then just nudge the scope a little to reacquire it.
If you feel that the drift period is too short, there are eyepieces with very wide fields of view that allow the drift period to be longer.
Best example I can give is my own. I have 6 scopes. Only one has a clock drive, my 30 year old Celestron C8, which is an 8" instrument. All my other scopes, 2" refractor, 80mm refractor, an 8" dob, 10" dob and 17.5" dob, are all push-pull. I only use my C8's tracking capability when I'm doing a sketch of the Moon or planets. If it is just visual inspection I'm doing the C8 stays in its case as my dobs take 1min to set up while the C8 some 15min and a whole lot of fussing to align the mount properly.
The dobsonian to a person who's unfamiliar with scope sounds like a very strange creature. All it is is a Newtonian scope mounted on a simple "gun turret" style of mount. They are extremely easy to use. They go in size from a table top 3" all the way up to 40" (1 metre) monsters that need a tall ladder to use. What they all offer is the biggest aperture for your $, and relative ease of use. The larger the scope, the fainter and more detail you'll see.
But, before you do your cash, I strongly suggest you go to an astro club meet or other star party an see the range of instruments available. You'll be able to see just how easy/complex they are to set up, use, and cost, and the many different accessories to further empty your pockets. This is the best way to make the best decision for yourself. I can suggest the 130EQ, but you may find the mount one tedious bit of gear and the scope ends up in the garage. You may find that the 90mm just doesn't reveal all the faint stuff that you want to see, and again you lose interest. A scope can be a very personal choice. I'd rather see you make the best choice for yourself than just do as I say. Who knows, the 90mm may be all you need.
I've added a photo of my 8" dob that I made the dobsonian mount for. I can comfortably use the scope just seated in a chair. It's movements are silky smooth - I saw to that. It is by far the scope I most use at home. The scope cost me $200, the mount bugger all.
Mental.
