Snow B2782B NOISE

Float Mode.....push your hydraulic joy stick all the way forward. You will feel some resistance and then you'll hear a click as it engages float position.

I see, great. I'll assume the stick will stay forward after it clicked.

Exactly. If you don't float and your snow blowing area is hilly you will dig in. I am pretty much floating all of the time.

I operate my blower in float mode about 95% of the time. When it is in float mode, the blower rides on its skids and is free to follow the gentle undulations of the roadbed under only the weight of the blower. That weight is consequently not on the front tires, a point that you will notice if you start to lack steering control, even in 4WD. Lifting the blower slightly will put the weight back on the front tires and usually steering control is improved at the expense of vertical compliance in blower height. On my rig, the act of putting the blower in float mode is tactilely (at the valve) similar to trying to rotate the chute clockwise due to "hydraulic regeneration". You can rotate the chute counterclockwise by feathered amounts & speed, but rotating it to the right is kind of a "bang-bang" process, once you get the valve handle past the "break- click" point. I often rotate it all the way to the right (it moves very quickly!) and then feather it back to the left to the point I want it. It sounds complicated, but really isn't. Google "hydraulic regeneration" for the reasons. As for WOT, I usually am about 200 RPM below WOT, and deviate +/- 200 rpm based on the need. The goal is to keep the speed up to keep the snow exiting the chute as fast as needed. Variables include snow depth and type, as well as tractor ground speed. You are going to enjoy this, pray for snow!:dance1: N. Fowler

Great tips, thanks gents!

OK. So the verdict is in. A well trained mechanic from another kubota dealership came down and although he said he never had direct experience with the snowblower he agreed it sounded too loud, like a squealing sound. It turns out it was the chain deflection. It was "tight as ****", so he loosened it up and the sound went down by half. HALF. Loud yes, but no where near what it was before. What a difference. He also said what another forum user told me, that it would quiet down a bit more in time as it was new.

We went through the process of taking the shafts apart and testing all other components individually to make doubly sure (at my request.) Sprockets were aligned, ball bearings were greased well enough, nothing rubbing. everything performed like clockwork. Kubota makes a good tractor he said, looks like a fine machine.

Thank you all so much for lending your personal insight. I hope that any new users of the B2782B may find this experience helpful.

Cheers!

Thanks for the update..Have fun in the snow.

BTW....I am going to mess around with the chain deflection one more time to see if I can tone the chatter down a DB or two.

Gosh, y'all are getting me so pumped to try out the B2782B on my B2650. My blower was delivered late, waiting on drive line components and hydraulic rotation and deflector components to be ordered. I had to send the tractor back to the dealer for other small stuff, and the blower was mounted and delivered with the tractor when it returned. I needed to use my loader and backhoe ASAP, so I had to remove the blower before I could even engage the PTO, listen to it whirl, or whip that discharge chute around. :laughing: Won't be long until the loader and backhoe come off, and she gets ready for snow duty. I will also have a box blade on the back for finish work and counter weight.

I'm hoping to get some videos posted this winter. I have asked Santa for a GoPro this year, so we'll see.... Thanks everyone for this great thread. I hope to be better prepared for some snow moving, if El Nino allows some snow here in PA. :thumbsup:
