Vermeer SC252 problems

[CTS]

I have a Vermeer SC252 grinder. Should be a great grinder but for a long time when it gets hot it is gutless and locks up and stalls when getting throught the stump. The grinder has to be re started 3 or 4 times per ave stump. REally really frustrating as it should be really powerful and easy. In fact I have a feeling it is gutless even when cold.

 

Any ideas???

Do you mean that the cutter head jams and stalls the engine ?

Yes. It get a lot worse when hot. I just feel it's gut less. Had the engine serviced and the head is spinning at the correct rpm so don't know what the crack is. I have used one before and it was great but mine is soo frustrating.

 

Help

 

Thank

belt tensions have you checked them ,are you trying to grind to much @ a go ??

is the outo sweep working ??

[CTS]

The belt tension is good. I have thought I might be pushing it too hard so backed off and it just bogs and stalls. I have thought about the auto sweep and have a feeling that I may need a new control box if that's the case. Expensive but might be worth the frustration it's causing. It's totally putting me off grinding when it should be a nice change from climbing dragging and chipping.

You say that head rpm is okay. If it bogs and stalls, yet the belts and tips are good, are you sure that the engine is good? Is the engine governor working and dumping fuel into the carb when you load it up?

[CTS]

I have no idea. How would I check that??

My 252 was rubbish until I unplugged the auto-sweep.

 

Now it great, I just need to go steady but its so much faster without the AS.
