Woods Belly Mower Vibration

DanMD · Aug 2, 2015

I bought a Super C with a 59 belly mower. I put a new set of blades on it and have about 20 hours of run time on this tractor. I notice with the mower on, a vibration that happens every 2 seconds that I feel up through the seat. It does it moving or in neutral. I think it goes away completely with the mower off, but am not 100% sure on that. Anybody have any ideas? Is this normal? It consistently happens every couple of seconds as something gets out of balance.

TIA,
Dan

I can't answer your question, but it seems to me if it is the mower it would be constant and not 2 seconds. Leave the mower off and run the tractor in all the gears, perhaps with the throttle at different speeds and see if you feel anything.

Have you cleaned the deck underneath that can cause a vibration cause of build-up changes air movement while blade are turning. Having a woods on a B for over 40yrs i have noticed the same.

Buddy of mine showed me to take each mower blade off, balance it on a screwdriver in a vise, and lightly grind off the end of the blade until you get perfect level balance. I think it helps. Very simple.

first, run tractor and ensure that vibration is not caused by tractor.

out of balance blades, would seem to me, to vibrate on every revolution. if vibration is from mower, check bearings.

I will take a look underneath and clean anything out.

Thanks,

Take the belt off and spin each spindle by hand, I would suspect a bad bearing in one of the spindles or an idler pulley

Those 59's aren't known for whisper quiet operation but they sure are good ones. They do some vibrating, some shaking, a little growling, and LOTS of great mowing.

Check and make sure that there isn't anything bilt up on the spindle to though off balance or a spindle with baling twine around it.

A customer brought his 300 to me last wek complaing about noise in rear end. Inspected brgs.,they were good,found loose wheel weight bolts and letting the weights flop around causeing the noise.

I pulled the blades off tonight and measured the run out on the spindles. I have .007, .020 and .030 runout. I'm guessing I need a couple of $pindle$.
