15HP Gas Powered Walk Behind Stump Grinder by SDI Factory Direct

had problems from the get-go materials did not hold up........ when it worked it worked well until things started breaking. customer service poor. very hard to get someone to contact you for replacement

Machines tires went flat after two weeks and won't hold air for two days now..must air up tires before using the machine ..used it on two stumps ..slow cutting takes alot of work..it will wear you out after a stump or two. Make sure you cut the stump at ground level first before you yr y to grind it .

A week old and the throttle will stay in position. Can’t get the brakes to adjust and stay locked so have to grind without it. Lifters were way off so it was missing really bad. After adjusting them, tieing the the throttle with a bungie, and placing a block down as a brake…. It grinds well.

I think this is the second review I have ever written. I haven't used another stump grinder, so others may or may not be better but this works great. I have removed 9 stumps (hundreds to go) up to 20' wide and about 20" high (as high as recommended) maple and white pine. I have extremely rocky soil and so it is hard to avoid them. Having hit even large granite rocks, so far, the rocks have lost. I don't recommend using it as a rock grinder though :) The sound changes when you hit a rock so you should know to redirect the blade. It started on the first pull and has every time except when I forget to reset the kill switch or I don't need the choke. It will remove the stump up to 9" below ground and though I have not gone that low, I have gone below ground. It leaves wood chips that can be used as mulch if collected before going below ground but when going below ground so far mixes the chips with soil and looks like it can be seeded for bio-degradation. There is a learning curve and each time I use it I get better at it. My friends are already lining up to borrow it. I think I am going to have them come to my house and remove two stumps as "training" before they can borrow it. LOL

Came with a badly bent brake arm, Brake cable broke and they sent me the wrong one and I sent it back to date no refund. The Engine blow up because of a faulty oil sensor and had to replace it. Miissing grease fitting, The cast iron Blades brake off to easily especially if your on rocky ground and for the price you pay for this Machine its cheaper to hire somebofy with a tractor. Plus this Machine is over priced for the benefit.

Throttles jinky and break never worked but have done 4 wicked stumps and made money.....It took 2 hours hard work...per where do I get parts??? Engine runs fine.I will check belts and Lube....

everything breaks on this machine!! do not buy!!!!

It runs great starts easy does a great job
