I think there were a lot of parts swapping as with other brands of tractors, between dad and i we have had seven g1000's, and no two were alike, either different hydraulic and water pumps, rear wheels, axle housings, front ends, Even looking at pictures on the net i dont think i have seen two g1000's exactly equipped alike, must have kept the assembly guys busy. Same goes with the A4t's, seems like theres never two exactly alike. It would be nice to know more of the specs on the A4t, and according to Mike they have the 1350 trans, and 950 finals, which makes sense, just wondering if the early A4t's used 900 finals. Also the trans would still need to be modified from a 1350 on the pinion drive gear because the A4t's had a straight gear that drove the drop box. We broke 2nd/4th gear on one of the 1600's and broke an axle on the 1400, were the only two major breakdowns we had with the drive train over the years, also put a few cluthes, throw out bearings, and spun the rod bearings twice on the plainsman. I try to glance at this forum a few times a week, there is a lot of knowlegable people out there, i appreciate any information that is passed along, i don't know a lot about the building of these machines, but i think with some slight modifications they would of had a good future in the 4wd tractor market. We also have a 4-150, but it is more of a row crop tractor than tillage machine, and like i read in an earlier post, if MM would have built the prototype A4T with the heavier finals and cummins power or 800 LP that would have been an immpressive machine.

MM did a lot of custom tractors that is for sure. They seemed to be very customer orientated. The A4t’s were made during most of the 50 series tractors life cycle. They were designed and built with Current 2 wheel tractor production parts. That would not be G900’s or G1000’s. Certain parts were and needed to be adapted. A 1350 trans was used but not as is. Some people don’t realize the lower shaft in the tranny is also is the pinion. That shaft had to be modified for a splined coupler. The same also goes for the differentials, they had a modified pinion in them. Modified and shortened for a u-joint. Hydraulics was modified to use the same parts. The 50 series 3 point was modified at the draw bar pin area.

I have three questions, one was there any factory installed 800 engines, my understanding they were all dealer or farmer installed, two are the 1400 and 1600 trans and final drive all the same, and three did the diesel 1400's have a 585 diesel or 504 diesel from the factory? Dad has two 1600's, both diesels, one moline, one plainsman. He also has a half breed so to speak, decals say A4T-1600 but transmission plate calls it A4T-1400. It has the four bolt clamp around the axle hubs while the two 1600's have the cone style wheels. We farmed with all three for several years, now they are retired to dozer work, the picture is of the 1400 but it also has the 585 diesel, thanks for any replies.

The A4T1400 used the D504 engine. It was the same engine as a G1050 except for a heat treated crank to provide better life if the dealer installed turbo was put on for more power. The A4T went in production in thr fall of 1969 along with the G950 and G1050. The D585 did not go into production untill the summer of 1970. At that time it was installed in the A4T1600. The drivetrain in the A4T1400 and A4T1600 was the same. A field installed D585 engine kit was available for people who wanted more power. Many of the A4T1400's were changed over. I think about 250 A4T1400 diesels were built. The first A4T's had the clamp sytle wheels. This is why they look like G900 axles. The clamp stle wheels were used to use up an over supply of wheel hubs. Production control had contiued to have them made after the taper lock style of wheels had went in production in 1969.

The LP A4T1600 went in production in the fall of 1969 with the 504LP engine running 2200 RPM. This was same engine as used in G1350 LP tractor which went into production at the same time.

In early 71, the Peoria branch convinced the factory to build 800 engines with the small crankcase flange to fit in tractors. 20 were built for dealer installation and the dealer could return the orginal engine for credit it it was not used. These immediately sold and the branch asked the factory in install them in A4T's. In the summer of 71 the factory started installing 800's in A4T's. 128 800's were made with the small flange crankcase. 72 were installed in A4T's/2655's at the factory. The rest were installed in the field. These provided enough power to make the A4T impressive. The weak link was 2nd gear in the transmission. With the 800 2nd gear high range was 5 MPH where most heavy tillage is done and the gears pitted guickly. With the A4T1600 diesel at 2200 RPM 4th gear low range provided a 5MPH working speed. The 4th gear was larger and lasted much longer.

MM knew that a heavier transmission was needed to realize potential of the A4T. The new heavier transmission with a power shift high/low had just started testing when White Motor decided to close the MM tractor factory in Minneapolis and this brough all work on a new transmission to an end.

There were some front axle failures on the A4T mainly when dualed. When the A4T project was started few people thought that 4WD tractors needed duals. This proved to be wrong. The higher HP A4T's were to use the G1050 axles which were heavier and could stand dual wheels better.

I agree with Brian, thank you for the info. I always wondered how much was used from other tractors.

There is a White factory service letter #351 dated 11-21-73 that listed the parts to put a D585 in 2 wheel and 4 wheel drives. That would G950's to 1400's.

I can only answer your first question. Their are two 2655's in Arkansas that were sold by Parie Imp. These tractors were factory equiped with hd800,s. They were sold to the dealers brother and have consecutive serial numbers.

The transmission was the same as the G1050/G1350. The axles were the same as the G950. The G950 used the larger 17" ring and pinion like the G1050/G1350. The G900/G1000 used a 14.5" ring and pinion.

The same as in all A4T-1400's and A4T-1600 diesel or LP. There was a new 250HP trans in development but never made it to production.

Would these be from a 1050 that are used?

Technically they said the A4t's had G1350 transmissions, but the G1050 had the same trans if I remember right. Only a few gears were different in the G950 and they shared them with the M670.

If I remember correctly they told us in service school the axles and differentials were out of the 900 series.. Of course that has been a couple years ago.
