I have an A/C 416 Hydro that will go when the transmission selector is advanced to slow, but if I try to advance it to a faster speed it acts like there is resistance and it will kill the engine. Does anybody have an idea what could cause this? It was working fine and just started doing this while mowing the yard. The transmission reservoir is full of fluid.

I get something similar on my HB112 hydro when my plow gets stuck on a root.  You just can't push hard enough to get more power to the wheels.  I think it has to do with back pressure in the system.  If your's does it with no load, I would be looking at the gearbox oil levels & axles.  Jack the rear end & spin the tires.  Do they move freely or not at all?

 

Edit: That or stuck brakes.

Could there be a restriction in the return on the hydro motor that won't allow that volume of oil through? Does it try to stall the engine in reverse as well?

Thanks for your suggestions.

I jacked it up and turned the tires to check out the differential, that all seemed to work properly without much drag. I opened up the reservoir and looked closer at the fluid. It looks like strawberry milk. I suspect there is moisture in the hydraulic fluid and the filter would not allow it through. I drained the fluid and am in the process of flushing out all the old fluid to put new DEXRON in as recommended in the operator's manual. Now the problem I'm having is to find a replacement filter. I get the shoulder shrug from everybody I try. The Allis Chalmers part number is 2027483. Does anybody know where I can order one of these filters?

If it is a Vickers with the external reservoir, a Napa 1467 will work.

Yes, it should be a Vickers.
