Chinese AGT/Mower King Brush Cutter Parts Source

[DesertRatliff]

Our farm budget didn't allow for a namebrand brush cutter several years ago, so I made the mistake of picking up a Chinese AGT brush cutter. It mostly worked ok on my Bobcat T450.

I was cutting the other night and think the gearbox let go (I have not pulled anything apart yet...that'll happen today) but in my quest to find more info about the attachment online, in addition to a parts distributor, I came up with pretty limited info.

Feel free to tell me how bad of a decision it was for wasting money on Chinese junk. You're preaching to the choir. That said, does anyone have a parts source for these? The dealer where I purchased from doesn't carry parts a brief search on Ebay seems parts are overpriced ($600 for a gearbox when I spent $2200 on the whole unit)

Thanks for the help!

Welp...started tearing down the mower. Just a few metric bolts to loosen and remove and the thing is completely apart. Having removed the parts, turns out the gear box is completely seized. I did find a nice part number on the gear box, though (1st pic)

The next step was to drain the gearbox. I removed the breather, tipped it in to my metal drain pan. Nothing. Not one drop of gear oil.

That's not good! But it does help explain things.

Pulling the dry gear box apart, I found the main shaft bearing to have a torn up cage and not all ball bearings present (2nd pic). That's not good!

I figured from there the bearing fragments likely took out the beveled gears, but other than some wear from having been filled with zero gear oil, they look complete (3rd pic)

The main shaft is seized on to the bearing but I want to get it completely apart to evaluate it all. Furthermore, I hoped the visable and detailed part number would yield a slamdunk for finding a replacement gearbox but the website listed is not secure and googling just the part number reveals nothing.

I'm open to your ideas for sourcing a gear box. If you know of a north American distributor of these parts, please pass it along to me.

That said, if I can get everything apart and it all looks in decent enough shape, I might just press in a sourced bearing and bolt it all back together.

Either way, if you've bought one of these pieces of junk, CHECK THE GEAR OIL LEVEL!! From the looks of it, there was zero gear oil added to the gearbox before shipping as there was no evidence of ANY gear oil in the box and the only thing that leaked on to my clean shop floor was dust from the bearing. Lesson learned.

I do not know where you are ,but I bought a different chinese manf. mower and the gear box had almost no gear engagement. So I bought another gear case about the same price that you were given. anyway I kept the old gear case the gears are ok there is one bearing that is bad. but it is just laying in the loft of the barn as a parts. so if you want to roll the dice and you are close to cleveland,tn. maybe it can be some use to you. I am sure we can work some kinda deal.

Oh man. Thanks so much for reaching out but I'm in central Oregon and know that shipping stuff around the country has gotten spendy these last few years. I'd be interested to read where you sourced the gearbox, though. I see some online presence on Ebay and Alibaba but that all feels like a gamble, especially from Alibaba. Did you just go off of specs (ie spline count, length, etc) and order accordingly or did you go off the unit's part number?

ok here is the info. I have on hand, www.chery industrial.com 1-516-280-7653, 66 inch Great Bear skid steer mower, gear box oil 80-90wt and 1.2 liter capacity. if I remember right the pump is a direct connect to the gear box, male on the gear box female on the pump,no lovejoy or other type link to connect the two housings. a friend of mine has a different chinese mower that is the lovejoy type is the reason I mention this,so there is more than one style . good luck

Mine has splined shafts on both ends (mine's in the pics), 12 splines on the blade side, 6 splines on the coupler. And I have a lovejoy coupler on mine. I searched the part number for the whole gearbox without dashes putting dashes in the search (HC 09031 1) and a bunch more options came up.

I ended up going with the one in the link below since it was the closest match I could find at the cheapest price (less than half the cost of the one on Amazon or Ebay).

I don't think anyone stateside carries parts for the chyna stuff. I'm not sure it would be a profitable venture. Good parts cost too much for the client. There's so many scams on baba it's hard to actually get what you pay for too, even if you do find the right part. Good luck.

I have used agri supply before and always had good luck with them on stuff. I wish they had a store in north ga. or southern tn. I have been to the one in tifton. ga. wow it is huge with all sorts of stuff.

please post if this works out for you, it will be good info. to have just in case.

 

[DesertRatliff]

Will do! I figured I wasn't the only one out there with one of these brush cutters. Thanks for the help.

if you have not done it why dont you count the gear teeth and see if you can figure out the gear ratio and see if the new one is close or the same. just so you know in case they are way different.

 

[DesertRatliff]

The new gearbox came in from AgriSupply yesterday (pretty badly boxed I must say, and super weird tracking...they sent a UPS tracking number that was never active and then it showed up via FedEx).

Here's the old gearbox and the new one that looks almost identical

Both say they're 1:1.93 gear ratios but I didn't count the teeth on either.

Included with the new gearbox was a solid coupler but I ended up deciding to use the old, chained one in an effort to isolate the gearbox from the pump a little better. I can always go back and install the solid coupler, I suppose.

Almost ready to work

Almost ready. I chose to add gear oil this time around, though

Thanks for the help!

after you get about 10 running hours on that gear box it might be wise to change the oil out, the last mower gear box I bought there were a lot of fine metal in the oil ,I used a oil vacuum to drain it and refilled ran more time on it and checked for metal again and there was far less. just as a fyi.

 

[DesertRatliff]

Good call! Nothing like a good break-in and then get the junk flushed out. Will do.

I'm in the exact same situation. any updates on how this worked out? If not this has been a great help thank you.

I've got about 10 hours on the new gear box, so I'll just say so far, so good. I did a post break-in gear oil change the last time I used the mower and am glad I did: the oil came out grey. I'll add gear oil changes to the annual maintenance list from now on.

All in, the mower works well and I still can't believe I was able to fix it for less than $200.
