ABC STUMP...My opinion is that you should stay away from a tow behind. With the large powerful self propelled machines out there you don't need to drive your truck onto lawns ect. You can also get at certain stumps with a self propelled machine that you would not be able to get at with a tow behind. I really don't understand why the tow behinds are still selling. I own a Rayco RG50 and a Carlton TRX8018 and I like both. The remote is real nice on the Carlton. I would recommend a RG50, RG50 Super or RG90 if you don't mind not having the remote. If you wanted a remote machine I would recommend one of the wheeled Carlton machines with at least 50 hp. I use my track machine on bigger jobs where turf damage is not an issue or there is a straight shot to the stump from the trailer. The remote machine is also nice because you don't have the swing out control panel which again can get you to some stumps where the Rayco could not get at because you need the space for the control panel to swing out.
