harmonyards posted:not trying to muddy the waters on you, but you may take a look at Williams GPs …..they are real stump pullers, and good runners, and sometimes can be had on the cheap...and most are twin can motors with flywheels....
I second this suggestion. In fact there are a couple of Williams Wabash GP9s—really a GP7—on Ebay, including this one. (Note that they have the same paint-scheme error that Rusty Traque points out in the Lionel J.C. Penny version.) They are well-built, heavy, and has harmonyards says, they are real stump-pullers. I have a K-Line MP15, with two truck-mounted can motors, and there is no comparison, the Williams GP9 wins hands down.
(If I have one criticism, they are geared a bit too high, so I re-wired it in-series, but that is pretty easy to do, and there are threads here that describe how. I ended up doing the same to my K-Line MP15, too.)
