4212 hydro with a little modification

Recommended Posts

simplejim
i posted a few weeks ago about a 4212 hydro that i had just hauled in.it was filthy with tree sap,hadnt ran in a few years and the release valve was was froze up and the tractor couldnt be pushed.well it sat in a corner of the shop awhile while i decided what i was going to do with it.not long after i got it i brought in a 12 craftsman rider with a good engine but but the rest was pretty rough.i finally got a little free time and thought i would try the advise i got here.i took the non running engine off the 4212 and installed the 12hp out of the craftsman and as soon as i started it the release valve freed up.i gave the mower a good cleaning and was suprised at how good the the paint and mower looked.i greased and tightened up the steering.it ran and drove great but something was missing so i went to the shelve and got an old pair of hubs off a very old david bradley or wheel horse i cant remember and to my suprise they fit so off came the short wide 8 inch rear wheels on went the the the hubs and a set of 6-12 mud/turf rear wheels and tires.now it looks like it should and runs great.{gotta have that tall bolted on rear wheel look,it just looks so much better}:Dthe tires do clear the deck and it runs and drives great and looks better sitting beside my ole 700 now.my only question is the the rear end strong enough to hold up to the 6-12s? mostly mowing maybe alittle snowplow or light towing work.

Pictures man... we love pictures!! :p:p:p Not sure about the hydro, but my guess is that if you maintain the fluids you will be hard pressed to break anything... this stuff is build rock solid. I used my previous Bolens H16 with an Eaton hydro to tow around a 2100lb camper in my back lot, did'nt even break a sweat. Been doing it for 7 years, and now the Simp is going to take over...:D Greg

actually it has miles of clearence at the seat deck.with the mower deck lifted all the way up.and the mower deck itself set on the next to highest setting it just clears the tire on the right side { the deck extends back farther on that side }.as the deck ajustment is lowered it gets farther from the tires.with deck all the way up and deck on highest setting it dont quite clear the deck but thats fine its plenty high one notch down.

simplejim, I have a 4211, exactly same tractor, except mine had a 11hp. (I am upgrading it to 18hp as soon as I get the parts for my 18hp engine) That hydro is pretty strong. It'll do a little bit more than most light duty tractors with a gear transmission.

Eaton, Dana, and Spicer are the most common Hydro stats. "Integrated hydrostatic trans axles rated to 260 ft. lbs continuous output torque and gear reduction ratios up to 30.6:1." all these fall into this category I don't foresee problems with your engineering.

thanks for the input guys i thought it would be fine too but wanted some other opinions.i usually stick to heavyduty garden tractors but this one is in good condition and i recently had been craving a hydro.with its small size i figure i will work well in tight areas and still be heavyduty enough to get the job done.Erick i think its your posts i have been following with much interest about the 18hp converson.i took my son to buy a dirtbike awhile back and the man has a good 20hp briggs on whats left of a box store mower [the engine has been transplanted on it.]he told me $50 for the mower.you have me thinking hard about swapping to a 20hp briggs:D.i mean as long as im customizing i might as well do it up right.then maybe some 8.50 or 10.50x23 ags on back.....and i dont like the front tires that are on it.......lol

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul

      folowing  this from a link at the downloads.  I just rescued an AC 920 with the lambodini diesel. I can' t download  yet .  Where did you find the PDF copy you posted. . I would like to figure out how to adjust the injection pump. 
      I assume it's a bosche, correct
