stump grinder how much do you think its worth ?

[Audreyrose]

I bought a Vermeer 630A stump grinder from some knucklehead on Facebook for $4,200. It works great it just needs a new belt tensioner and new teeth. My husband was just diagnosed with s tage 4 throat cancer, so we had to shut down the company. I posted the stump grinder everywhere from offer up to craigslist, no one is interested. I started out asking $4,200 but droped it to $3,000.  I have to sale it to get Christmas gifts for my kids. Does anyone have any advice? would I have better luck if I cleaned it up and repainted it. Or if I ordered the Vermeer stickers for it? I have no clue why it has no stickers on it. Any advice would help thanks
