My LED project (26" 3X HD 420CC)

I broke 2 shear pins last year swallowing up newspaper rolls, so I decided to put two 27W Leds on the bucket. These lights are IP67 so they should be able to handle the abuse of the occasional snow drift and blowing snow forward.



OEM circuit (modified by me for my specific blower)


LED circuit. Notice that the original headlight is now DC. On Off On control for: Both, Off, and Headlight Only. DO NOT TIE THE DC GROUND TO THE CHASSIS, OR YOU WILL HAVE A VERY CONFUSING PROBLEM TO TROUBLESHOOT.


I didn't want to drill anymore holes than I had to... I don't mind replacing the cable tie mounts once a season. The belt cover was a perfect place to drill some holes for hole-mounted cable ties.




Project Box from Sayal Electronics. Typical rectifier, cap, and fuse circuit. I had a harness from a surplus store in my toolbox for years, otherwise I would have cut one off at the autowreckers.


All wired up, you can see the 1157 LED light from Princess Auto. My goal was to keep the circuit under 60W. CC Canada tells me that the stator can put out 5A. My blower runs at 16VDC at WOT, so that's 80W


CC left a perfectly sized hole for my On-Off-On switch The project box mounted with a couple zip ties. I have just enough room to pull out the fuse.


I don't have a pic, but there is a HUGE improvement in visibility.

2.2 Thanks for the pics on your very clean install. This has given me some ideas for my
LED upgrade on my Ariens.

I'm about to install 1 of the same lights on my Honda, do you need 2? Or is it just for the cool factor?

HS 928 TCD. It's Canadian eh! (Sure I'm done modifying it, for now, until next time.......)

I bought 2 because other people on here were buying two, and they seemed happy with the results?

I guess it depends on your situation. There are no streetlights where I live, so the more light - the better. Every time I bumped the machine into something or broke a sheer pin it was because I couldn't see what was in front of me.

If I was to start over I would consider doing something similar to the what CC did for the newer 30" track model. The offroad guys call these "light bars".

I'd like to see them in action - try to post a pic when you can.

I installed my single light after lunch, extremely bright. I can only imagine how bright your rig is.

Thumbs up

I bought a Cub this year with the light bar. I was using it last night out back near the trees and it really brightens things up. Another innovative idea from Cub Cadet ! I am very pleased with it

Thanks for the post CanadaGoose.

The LED light bar you have mounted is MTD/Cub/Troy/White optional part number 753-08484. $88. I guess the dealer must have put it on because of the higher height of the housings on HDs.

MTD says it works with any 2012 or older snowblower series 500, 600, and 700 with a 3A/5A 20W/20W PowerMore engine.
MTD could not tell me the output of any stator on any engine or series of snowblower.

Problem: 20W/3A = 6.7 Volts. ??? 5A x 12V = 60 Watts. ???

A stock 1141 bulb uses 1.4A at ~12V. That's 20W.

My light meter read 333 LUX directly in front of the headlight bulb and at the equivalent depth of the back of the chute worm gear support post. That distance from the lens cover surface is 16 inches, FYI.

The heated grips start at 1.1A and that rises to 1.4A when they just feel warm after about five minutes, FYI. Again, that's about 20W.

So where are they getting 3 and 5 Amps and then quoting 20/20 Watts for the two outputs?
I believe the 20/20 Watts is the rated power of installed devices from MTD or Cub.

-----------

So, I have a few questions for you that should help some of us out.

How is the 6 LED light bar mounted to the housing?
Bolted?
Double backed 3M Molding tape?

Next, can you measure the actual current draw at full thottle and idle?

What is the voltage versus ground across this light bar at idle and FT?

Those numbers may sort of settle the stator output questions about a Cub Cadet or MTD blower for a 357 or 420 CC motor stator. I doubt they are 3 or 5 Amps.

What's the brightness of an 1141 bulb? It's rated in the literature at about 180 lumens. Lumens is not LUX and they are not interchangeable.

I have spent tons of time searching Troy, Cub, MTD, and Zongshen engine spec's for the written down engine spec's for the two stator outputs or ratings.

I can't find a thing.

Any help here would be good info for all of us.

FYI, for others, some 2015 Craftsman Pro series blowers have a LED headlight. It's part number 925-06095. $24. "LED Assembly" but does it have the LED with the socket? MTD told me, "Yes".
Cub told me it won't fit but the panel/console numbers for my Cub and their Pro series blowers are identical for that LED part, the lens cover, and the reflector.
Go figure.
This LED is sort of flush with the back of the lens housing molded into the entire console. It looks like a small LED flashlight is mounted behind the back of the reflector housing.
Blower 31AH54TI799 is the literature # (273-) 88870.
Blower 31CH95SI799 is their # 88876.
Blower 31CH97SJ799 is their # 88878.

Thanks for any current and voltage values you can provide.

Stefan

Hey there Stefan
How is the 6 LED light bar mounted to the housing?
Bolted?
Double backed 3M Molding tape?


My Cub Cadet 3X HDT came from the factory with the light bar already mounted. I know this was the only model my dealer had in stock that came from factory with mounted light bar. The other sizes and the 30 " HD wheeled did not have the light bar. I'm not sure if this is something Cub Cadet is going to start providing on all of their HD models or not. As to how it is attached , I think it might be a combo of 3M tape and bolted. I'll have a look tonight and try to get some pictures posted. Also next time I have it outside after dark I'll get some pics of the brightness it throws . I actually intended to do this by now but I keep forgetting to take my phone(or camera) out with me

As for measuring current draw and actual bulb brightness , I'm afraid that's beyond the scope of my knowledge and tool box. Sorry .
Maybe 2point2 could shed more light (pardon the pun) on this for you.

Best of luck and I'm sorry I couldn't help you out with most of your questions

Goose
