Anyone used a front crank driven PTO hydraulic pump for high gpm flow?.. Massey 4253.

Hi, I have a 4253 Massey that's been a good tractor the near 20yrs it's been on the place. My late Dad bought it a few years old. I have a red series Hoelscher 1000 hay accumulator that runs behind my Massey Hesston 1837 small square baler, and it needs a minimum of the 17gpm that my Kubota M108S (and it could use more gpm -- dealer said the John Deere tractors' 20+ gpm was ideal). I don't have a Deere currently... But have been looking at the 4x55 series... But I got to thinking about the Massey again...

I don't have to use the open station Massey for baling (which is good, as it's an unusable 10gpm flow system), but it runs good with the baler... Just not the accumulator. I got to thinking that the front PTO pumps, like Alamo used on lots of makes and models, including those 4000 series Masseys, might be a good solution. I looked up a manual on Alamos site and they have over 20gpm... Just what I need.

The important thing is strong gpm in all load conditions for consistency of accumulator operation ... The arm on the accumulator has to have very rapid return speed to rest position to clear the next coming bale from the baler.

Has anyone used those type pumps (and tanks, etc, for the hydraulic system) on a tractor for an auxiliary hydraulic system? If so, how/where did you source the parts?

Thanks,
Russ...

I own an old British Tractor called a Nuffield 465.
The hydraulic systems on these machines were too small for things like front end loaders.
A number of owners mounted front engine driven pumps to greatly improve the flow rate.
I am providing a couple of images.
The challenge is to decide where you are going to store the hydraulic fluid. Some mounted external tanks while others made connections into the reservoir of the existing hydraulic system.

Hi Dave, ap

Hi Dave, appreciate your response, and especially appreciate the pics. It never occurred to me to think of the existing tractor reservoir. I'll look into that. My cousin has a older Massey 50 with a front pump on a very stout industrial loader. Come to think of it, I don't remember a tank on it. I'll ask if he used the tractor's tank. On my accumulator the volume of fluid displaced and returned is only two cylinders worth, assuming the extremely long lines are full. Seems like there would be a Alamo salvage yard or a business parting them out... I only bring those up due to the many Masseys of that same model I saw in interstate roadside work and fitted with flail and boom mowers from Alamo. But fitting to just some aftermarket pump and perhaps using the reservoir of the existing tractor hydraulics is the way to go. Thanks, Russ.
