First check for a bent blade Then check for a broken spindle. Then check for broken metal on the deck or a broken/ disconnected deck hanger.

New tiller makes grinding noise when trying to run tillers

if it has a clutch
most small units just run a dog that you engage with a swift motion at low idle speed of the motor
have the tillers free above the dirt so they can turn with out any load to inhibit the dog engagement

Your blades engage with a cable and the cable somewhere is bunched up. You will probably need a new cable.

Why does unit run sluggish when blades are engaged?

if you are talking about before even moving, it could be grass and dirt caked inside of the deck. If you are talking about when you start mowing, it could be front to back height adjustment. owners manual has instructions for adjusting deck height.

Have a Deere 160 Lawn Tractor. When trying to engage the blades; via dash switch; the engine bogs down and stalls almost immediately.

"suggestion" .......While engine is "NOT RUNNING" ...I repeat "NOT RUNNING"... And after looking at owners manual to be sure that all brakes are disengaged and that drive belts are routed properly....... reach underneath and see if blades will turn freely.. there may be something such as string,wire,twine,ribbon,or tough grass and fibrous weeds wrapped around the spindle between the blades and the housing....(this will show by the blade or blades being difficult to turn while dis-engaged.) one can often cure this by putting mower up on blocks on one side or the other (high enough to reach into blades without them being obstructed from turning)...and using a screw-driver, awl,or needle nose pliers to extract whatever is binding the blades from turning...... .... there may also be a lack of lubrication... which will show itself by a grinding noise when forcing the blades to turn by hand... this can sometimes be cured by pumping grease with a grease gun into the zert on the top of the spindle (spinny thing) (the zert,or grease recepticle) is usually on the upper side of the blade the center of where the drive belt goes on the pully that drives (turns)the blade.... excessive grinding may be an indication that spindle(s) .. (spinny things) are worn and need to be replaced...
if all seems to be spinning freely when may be that the carbeurator or governor needs adjusted or the fuel filter(s) are clogged......or even that the oil in crank case is low creating a low compression (power) issue...a general maintenance should cure such.. .....None of these is are very time consuming... ..Good luck and let me know!!!

Grinding when mower is engaged but no apparent damagewas found

You may have a bearing gone on one of the quills (blade shafts).

Remove the mower deck from your tractor,and check each quill for play in all directions. If there is any movement other than spinning, you will need to replace.

I can't get the removalable bowl off the grinder. I think the blades are stuck.

This seems to be a widespread problem on units manufactured in 2007 and later.

Unplug the unit from the AC outlet. Remove the six screws that hold the lower plastic cover on the motor base (four screws are hidden under the adhesive rubber footpads). This exposes the lower end of the motor shaft, which has a slot in it. By inserting a flat blade screwdriver into the slot and holding the cutting blades with a rag or a wad of paper towel to avoid cutting one's fingers, it is possible to twist the shaft back and forth about 90 degrees. You may need another person to help, because one needs to perform this twisting action while pulling the motor base away from the grinding cup and blade assembly.

Once you get the @&%$#! thing apart, reassemble the motor base. (With the slotted motor shaft, why didn't the designers simply put a hole in the plastic base so one could stick a screwdriver in without disassembling it?) Plug it into the wall outlet and use a small object like a toothpick or matchstick to activate the recessed motor switch so you can spin the motor without the grinding cup in place. Use the blunt edge of a small snap-blade utility knife as a scraper to gently scrape the plastic pin of the motor shaft as it spins, much as one would work a wood turning lathe. Periodically check the fit of the brass hub of the grinding cup on the plastic pin. Continue to shave the pin until the grinding cup slips onto and off the pin with no resistance. Take care to machine the pin uniformly from top to bottom; avoid making grooves.

Why this mechanism worked properly when my grinder was new about 18 months ago and suddenly decided to get stuck this week is a bit of a mystery. The unit in question has been used since it was purchased exclusively to grind flax seed, but the ill-fitting pin normally doesn't come into contact with foods, anyway. There was no obvious evidence of swelling of the plastic due to heat from the motor or oils from seeds. Since the blade and hub are free to travel up and down on the plastic motor shaft pin a bit, I suspect that on occasion the blade doesn't settle properly and the clutch doesn't engage, allowing the pin to spin in the brass bushing until it starts melting, and then the hub settles so that the clutch is fully engaged. This may happen in a matter of just a couple of seconds of operation. Once that happens, the pin conforms to the microscopic grooves inside the brass bushing, allowing it to still turn slightly relative to the motor shaft, but locking it on so that it can't come apart. If Cuisinart had made the pin more tapered and the hole in the brass bushing to match, much like a Jacobs taper on an industrial drill press spindle, this would be much less of a problem.

BOTTOM LINE: Before loading the grinding cup and starting the grinder, push the blade hub down with your finger to make sure the clutch is fully engaged.
