Default Snowblower/PTO load on BX2380

Question about how hard to load up the engine/PTO on my new BX2380.

I mowed several times with my 60"mmm, engine didn't seem to know the mower was even attached...

My new 55" commercial grade BX2822A snowblower is a different story. Blowing about 6" of heavyish snow yesterday in Minnesota and the BX2380 definitely knew the snowblower was attached. Obviously I can slow down and decrease the load.

My question is when running about 3,100 RPM, when I started to dig into the snow at a moderate clip the engine RPM would drop to about 2,800-2,900. If I went slower, the RPM would be higher of course.

The question is, from 3,100 RPM, what RPM drop would be considered safe/appropriate/optimal when loaded up? I can vary my speed to stay in that safe/optimal engine load?

If you all could give me your opinion based on:

1. A fully broken in engine.

2. My current engine that has about 12 hours on it.

And, I'll add, I absolutely LOVE the machine, the mower and the snowblower.

Thanks to all.

Your tractor HP is rated at 3200 rpm engine speed. In my experience with snowblowers, if you start dropping engine rpm's by 10%, then things start going downhill pretty quickly. That is, if you load it up and start dropping below 2900 rpm's, the impeller speed goes down and does not clear as well and just starts loading up more... which quickly starts bogging the motor down further.

This seems to be a point of contention with some here; but when snow blowing, I would run at full throttle. Running lower than that just slows the impeller to make it more difficult to clear the snow. That just serves to load it up quicker, (plus reduce the available HP and torque), causing the engine to load up quicker which also makes it harder to react to keep it from bogging down further.

A 55" blower seems a little large for 17.7 PTO HP. I had a 23 hp tractor with a 50" blower which worked well most of the time, but I think I would have had to slow down more with a 55" blower. In the end, you may be able to actually get done faster by slowing down and taking a bigger bite than I could (maybe even cut out one pass). But I know me, and would try to push it fast than I should causing it to load up more... but that's just me.

In the end, all you can do is run it and see what works for you based on the variables given to you (i.e., snow depth, snow wetness, and snow density - how packed it is). You are not going to hurt your tractor as long as you do not lug the engine all the time.

Good luck.

My BX2360 has never worked harder than some sessions with the 'blower.

A snowblower eats a lot more HP than some other implements, according to some of our members here on OTT. You're taking 6" of wet/heavy snow 55" wide, it's A LOT of stuff thrown a long ways.....That's work, and work=HP.

Like conropl said, work it. You'll get it figured out pretty quick and will become second nature. A small decrease in RPM's is expected and not harmful, within reason.

To your questions, I wouldn't go lookin' for any 4-foot drift bustin' with just 12 hours. Work it, but don't overdo it. I think what you're doing now is spot on for break-in, and honestly, I might push it just a little harder..just a little, for now....

I have the same blower. When I bought mine the dealer told me 2380 was good 2680 was better. Coming up on my 3 rd winter and my 2680 has no problem handling lots of snow up in Ontario. Was money well spent as far as i'm concerned.

Some implements will use all the power you can give them. A snowblower is one, woodchippers and hammermills are two more. I often make black smoke with my BX24d when blowing snow.

I keep the RPMs up but take less bite( width).
Go sloow first full width cut an dget RID of that snow, then take 1/2 or 1/3 or 2/3 'bites' and get RID of that snow, far,far away. You'll know real quick how much 'width' of snow you can get RID of.
If possible, it's better to remove 3" then another 3" , not all 6" at once, though I forget some people actually have to work, have families, etc.
I wait for 4" THEN remove...more than that,especially if heavy is a task(hard on) for any snowblower.

Like eserv said, I made some black smoke just a few minutes ago with the snowblower....we got up to 31 degrees F.

Stuff was heavy .....

I'm using BX1880 here, so I have even less to work with than the 2380. I frequently have to go slower than I want to (forward speed). I run the snowblower at PTO designated RPM, which is were its designed to be run. Even with light snow, you do hit a max clear rate where it just can't empty the snow any faster and it starts to push the snow in front of it. I do regret not getting a bigger engine on those really wet slush days but other than that, it works well and I am happy with it.

I have made my peace with the fact that its not a plow, and so I can't clear the snow super fast. For me a plow is difficult because there aren't a lot of places to push the snow. The blower may be slower, but it gets rid of the snow where I never have to deal with it again, which in the long run saves me time.

Same!

This last storm I did a full foot and had to slow at times with my 1880 or it simply couldnt move the snow fast enough. I usually dont do 12"+ in one pass. I still eat through the 4' high snowbanks the plows leaves with ease! I run PTO or higher if I'm bogging at all in really wet stuff. After walking behind 200# beasts for 30 years I dont think I could complain even if I wanted to!

I think you have a good idea of the sweet spot while blowing snow. Other posters have mentioned the quick downward spiral of lowering RPM > Increased snow load in the blower, leading to a quick stall if speed or snow ingestion is not reduced.
Slow and steady wins the race in snow blowing. I don't excessively bog my tractor down on a routine basis, and I certainly don't stall if out.

My current tractor has some cool transmission features that I want to test out in deep snow... "Stall Guard" that slows the traveling speed down under heavy load. I've tried it out mowing a few times (thick grass, uphill) and it works well, but honestly my seat-of-pants control seems to work just as well if I pay attention to what I'm doing.
