Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

This is a Honda HS621 single stage snowblower.  It is at least 10 years old, I think more like 12 years old.  It had been in good service all these years.  However, most of these years it did not receive the TLC it should have gotten considering the caliber of this machine.  I thought it would only do justice it I to take on the task of making it look beautiful and fully functional again.

Things that were done in the last two years:

1. Auger housing completely stripped down to bare metal.  Primed and painted in black gloss.
   
2. Metal auger repainted also in black gloss
   
3. New set of OEM rubber paddles and augers
4. New OEM drive belt
5. New scraper bar
   
6. Replaced missing or rusted screws and various hardware
7. Repainted red plastic top cover and side belt cover with Krylon Fusion red paint
   

Things to be competed shortly, parts on order:

1. Replace wheels, washer, and cotter pin
2. Replace springs on the chute ratchet
3. Replace chute collar
4. Affix new Honda and warning/caution labels

That should pretty much covers it to bring it to full showroom condition and operational specs.  Total costs of parts ~ $200, $30 in paint supplies, and several nights of work. 

And now here are a few pictures. 

Is this a floor model just for showroom sakes or will it be brave enough to venture outside

Great Job !

She's a beauty but not afraid to play dirty.  It will see plenty of action, no garage queen here.  :)

I like to run them hard and put away wet. 

It's a tough snowblower, should handle hard work just fine.

I know it's kind of crazy, but been thinking about removing the GX160 and transplanting a GX200.  Direct bolt-in to the frame, a little bit of work matching up output shafts to pulley though.   

There are GX200 clones available for cheap.  Maybe I'll put the GX200 on a second 621 donor frame.  I hate to butcher up this one though.

I'm also thinking about picking up a Honda HS35 for a restoration project.  She's really old and replacement parts are rare and really expensive.  I mean really expensive!  The HS35 is really well built and makes every new single stage snowblower look like toys.       Just the chute crank alone looks tougher than half of the snow equipment at Home Depot.

So many things to do, so little time.

You got a very capable Toro 221Q, I wouldn't have second guess that purchase.  I would take a second or two thinking about having both the 621 and the 221Q though.  :)

I read the favorable reviews for this "appliance paint" on the amazon web site. But the paint says it is for inside use only.

Should that be a concern with a snowblower application?

"Rust-Oleum Specialty Appliance Epoxy is an ultra-hard, moisture resistance enamel that is specifically formulated for indoor
 metal surfaces. It provides a smooth, washable surface for refinishing the exterior of appliances such as refrigerators,
dishwashers, laundry machines, and other indoor metal applications (cabinets, tables).
Do not use on objects exposed to heat (stovetops, oven interiors, etc) "

I read the label and check the recommendation before using this paint.  It has the properties that I was looking for, "ultra-hard and moisture resistance".  It is hard, smooth, and slippery, perfect for a snowblower bucket.  There wasn't anything else I could find that was reasonable in price and available in a rattle can.  So I took a chance and used it against the recommendation. 

Reading between the lines, I'm interpreting that the paint was not formulated for thermal expansion of the substrate at elevated temperatures (ie chipping and cracks) and/or resistance against breakdown from the sun's UV radiation being stored outside.  Or that it has not been thoroughly tested for outdoor applications.  Neither of these conditions are applicable to my snowblower.  Operating / storage temperatures are 0-100 Fahrenheit with minimal and non-continuous UV exposure.

I will report back how the paint holds up after several years. 

Use it at your own risk, YMMV.  The worse it could happen is that chips and cracks may develop.  You have to strip it down and repaint it.  But it's no worse than any other paint that is on there or rusting exposed metal.

I have been contemplating the GX200 transplant on this machine as well. I put a clone GX200 on a Honda HS520 and I was quite impressed with the end result.  So are there differences in the output shafts (GX160 vs. GX200) that would come into play?

I would agree that the HS35 is a beautiful piece of engineering (sans clutch).  http://www.youtube.com/watch?v=QGUq5huKGiE

The GX200 is basically a GX160 engine block with longer stroke.  All the engine mount holes are the same.

The GX160 engine that is in the snowblower has a different shaft than a GX160 / GX200 that you buy off the shelf.  Can't remember the detail now.

Nice overhaul!  Beautiful!    It's a shame Honda (and many) are offering lesser, more economical engines and parts in their present snowblowers.

If Honda offered the HS621 motor in their HS520 model  - I'd buy it in a second.

The HS35 was Honda's first foray into the US market and it eclipses all single stage snowblower, IMO.  The majority of that beautiful engineering is hidden under the plastic top cover that most people will never see.  The engine mount, wheel mounts, handle mounts, and auger housing is one welded piece.  It is more of an automobile unibody  / space frame than a snowblower.

Check out this diagram and you'll see what I mean.  See item #4.

Auger housing.

It has control knobs on the console that is more fitting on an automobile than a snowblower.

Here is a longer video showing how well it handles the heavy stuff.  It doesn't throw very far, but the throughput and the pace at which it moves is quite impressive for a 3.5 hp engine.
