 Guys i have some questions about that JBII transaxle.I just recently hauled in what appears to be a very rare tractor. It is a AMF AMFTRAC 1414.I have only found two other owners on this and another forum and info seems almost nonexistent but i have found two parts tractors in a salvage yard and some original ads along with manuals for the tractor,deck,dozer blade and three point hitch.I'm fairly hard to stump when it comes to transaxles but i had never seen one like this until now,its the same as the JBII trans in the T63 frame.What can you Bush Hog guys tell me about this trans ? I know you guys are in depth experts on these machines so i think i have hit a match in the right place. Is it a stout transaxle ? what brand and model is the trans ? What brand and model is the pump ? Does anybody have any pictures of the inside of it ? Is there a manual for it in the manual section. This AMF 1414 seems to be a big tank of a tractor,i really like it and plan on trying to get it back into good condition and the start of that is the investigation work. Thanks for any help that you can offer.

olcowhand Daniel will be the guy to answer your questions for sure. He has forgot more about these JB's then I'll ever know. Did you post more photos of this GT here in another thread?

What are the parts tractors? Are they M/F or B/H?

 

I'm also going to make it's own thread in the BH forum..

Thanks Brian i know Daniel is definitely an expert on BH and the rest of you BH guys here seem to be well educated in these machines.I did post a thread in the Massey/AMF forum with pictures but i have taken several more since that i can post if anyone is interested.I have been trying to get pictures of other model/serial tags from the few others that i have found.As best i can tell it appears to me that my tractor's serial number is 0006 but i'm not sure how to read the tag.Its a very stout tractor with some interesting features.

The parts tractors are AMF 1414's.Several of the AMF tractors had MF counter parts (and Dynamark plus another brand or two) but the AMF 1414 is a stand alone model so with parts being mostly specific to it i was glad to find a couple of parts tractors.

Hydrstat is "Hydrogear" brand. But it it is just a hydrostatic pump, coupled to a gear motor.  Less efficient than hydro to hydro, but a tough system just the same.   

At the moment I can't recall the maker of the axle unit.  Axle unit is a single speed, with a bull gear instead of pinion.

 

I'll post more later.  Gotta get to work.

From looking thru the manuals section it appears the HD12 uses the same transaxle and pump ? On another note the differential in mine appears to be limited slip.Each time i have hung or accidentally choked the front wheels on the concrete pad backing it in the building both rear tires spin on the concrete which makes me very happy.Were all these transaxles limited slip ?

HD & JB....same units.  Not sure if limited slip.  The only one I've had apart didn't appear to be.    Still not had any time.  My calendar is pretty full the next 2 weeks.

FYI: Early JD 140's have that same hydro unit. I'm not sure on the limited slip either but I will say that I've never gotten stuck on my 140... seems like one tire will spin a slight bit and then it goes... Guess I need to test it out.

 

edit: There are some pictures of mine here: http://gardentractor...jd-140h3/page-5
