I have a 60 flex and float mower and the gear box mount has cracked. Anyone have experience welding these gearboxes bases.   

my tractor is a gt 19 and I don't exactly use the mower on perfectly flat ground, I abuse it for sure.

I have searched out gearboxes on the web and I think I would rather like to get it welded.  I don't weld myself so will have to get it welded. if anyone has had this issue let me know your experience.

Welcome to GTT. I would think that this is very dependant on the welder. I've seen some guys do miracles and others not so much. There are alot of variables, it takes a really good welder to give you what you want. Good Luck, Rick

I would find myself a welding shop and stop by and talk with them to get your answer, they most likely are going to want to see the part in questions.

I've tig welded a few. stripped out bolt holes and ears/tabs back on the sides. Have yet to try mig welding one. its going to need to be torn apart, and pre-heated, 500º works good, kitchen oven works as long as it clean otherwise the woman will want to know what you did to stank up the whole house 

it's also dirty cast, tends to grow after you strike an arc, jumps on to your electrode, trapped air, did I mention dirty, the dirt/sand/crud just keep coming, stuff more rod in

I assume it's cast iron. I would look at brazing it rather then welding. Bronze brazing or flame welding is a lot more forgiving on cast iron and doesn't require as much preheating and extended cool down times. I have repaired a lot of cast parts this way and used them in high vibration/ impact areas.

I wish they were cast iron but they are aluminum. grass tends to collect around them and rot them if you don't keep your deck clean.

If a man is good with a tig welder he should be able to weld it, with it being aluminum it will need to be taken apart and cleaned and preheated prior to welding, but it should be weldable.

 

In my younger days I would not hesitate to weld it.

Welcome to the forums! 

Where is the crack located? Years back I had used a product called Quick Metal for repair work. A heavy duty epoxy like product. I am not sure if it would knit to this.

hi all

just to give you an update, i tried the cheap easier way.  Cleaned it all up took it all apart, what a pain getting that gearbox off the deck.  I used a product called jb weld.  The break is on one of the ears for one of the main bolts to go thru.  The break extended along the base of the gearbox.  The no weld repair held for some time but broke again.

reading some of the posts, i never really considered looking at the pto shaft to make sure that was in proper shape too.

did i say i abuse this mower deck, so really my fault.  lots of trails and uneven ground to mow on with your typical rocks and branches all over.

my repair got me thru the summer but i will eventually try a weld shop or better yet keep my eyes out for a junker parts deck.  Tons of snow here now so my gt19 is busy blowing snow.

tks all for advice so much appreciated.

where a bouts are you located? there was one for sale (though I think it was a 48" I think you can swap the gearbox to your 60" deck, it was off of a GT 17)   Rockford IL Craigslist, seller was in Roscoe IL.

 

(NOT the deck for sale that I speak of) but I have a 48" one that I have never mowed with yet but when I spin the box by hand (PTO shaft is hanging off the deck gearbox) it spins over rather hard.
