Mower will not ramp up to normal speed - Garden

Posted by Mike Pyeatt on

  • Mike Pyeatt Sep 26, 2009

    mower starts but oscillates between idle and almost normal speed. air filter not dirty and brand new gas used. Mower worked last week and now doesn't. now sure how these new auto choke mowers work or how to troubleshoot issue.

    What are you referring to as normal speed. Do you have a tachometer? If so, it should be set at around 3400 rpm. If it just won't speed up, then it's possible someone tinkered with the adjustments. What type of motor is on it? Need to know this before we can go any farther with helping you. Sorry.

What do you mean by Ramp UP . Thats not proper. If you mean does not come to full RPM's thats correct. You didnt specify what engine or brand of mower. Most engines today have a preset speed of 3300 rpms. this is controled by a spring and link thats attached to a tab and that tab bent properly will increase or decrease the rpms. It could also be a sign of a carb problem . Best you take it to a tech/lawnmower shop and have it set to factory spec's

Condenser fan does not come up to full speed.

These Ptac units are advance system that are designed with variable speed motors that modulate in order to save energy, This is normal operation, because starting a motor at a lower speed rather than the conventional high speed will save energy, which translates to saving you money. As the load increases (heat) on the condenser coil, the fan will ramp up accordingly.

Drum is making a loud banging noise during spin, it is brand new

Some banging or knocking during the ramp up to spin speed in this washer is normal. It is difficult to determine whether your washer has a problem or not based on your description. This banging lasts for varying amounts of time until the load is balanced and the washer ramps up to the full spin speed. If the load can not be balanced on the first attempt, the washer will ramp down and then tumble and attempt again to ramp up to speed. This may be the same thing that you are hearing when your washer ramps up to spin speed. Since the washer does spin at the full speed, there is not likely a problem with the washer. The components are designed to withstand repeated vibration and reasonable banging or knocking. The washer will vibrate to some extent at high speed. If you feel that the vibration is excessive, I recommend that you check the stability of the leveling feet. Press down on the diagonally opposing corners of the washer to check for play. If the washer rocks at all when conducting this test, I recommend that you adjust the leveling feet to eliminate this play even is the washer is not perfectly level after making this adjustment. This may help reduce the banging and vibration. Other than that if it is brand new call the people who you purchased it from so you don't void any warranties by taking it apart.

Can I replace the blades on my 38in MTD/Yard Machine ride on without removing the deck? ie. from underneath.

If its in good condition you might be able to but be careful so mower doesn't fall on you. I've used my car ramps and backed the mower up the ramp and was able to do it safely. If you have any difficulty removing the blades, then I'd take the deck off. It really isn't that hard to remove the deck.

Can you tip the mower over to change or repair the blade? How do you do this.

don't advise tipping it over on its side. You can run it up car ramps, jack it up, eigther way should give you enough room to get to blades from the bottom. I use a comealong hooked to the rafter and lift the front end and stand mower upright real good acess, easy on the back.

Danfoss FC202 VLT Start-up problem

I didn't see what these drive application was for. Is it for a fan or pump?
I assume you've entered all the motor data, FLA, RPM Voltage, KW etc. If you have three of these you must have experience with these drives. I've only used these drives on fans, and once on a pump.
Have you tried the Automatic Motor Adaptation ? (AMA) Have you programmed the PID start speed? Read the note about this feature as I think you have to have min speed set at 0 .I know you said you tried changing the ramp up time. If this is on a pump, the ramp up time may be too slow causing the motor to draw too much current when it's pumping way down on the pump curve. People would have a tendancy to make the ramp up time loonger, to make the load easier to start, however the torque requirement on a slower speed could be so high, the motor is overloading. I'd like to know what you find out, pleas post your solution. Have you contacted Danfoss or your local rep?
