Post Hole Digger/Auger Down Force

[MMM]

I don't know if the bearings and gears would stand up to that kind of load very long. We're not talking a couple sacks of feed here. Could be 2000lbs or so depending on cyl size, etc.

We've been arguing about this over at MBN.Everyone has good points.But with the difference in soils here,sometimes over the course of a little rain,I want some down force.But I am now inclined to go with weight.Noticed in the TSC "Blue Book",that the PHD they sell comes "down force ready" and optional weight kit.But for me..the ponit is moot,because the TPH on my homemade tractor has power up and down by design.

Ive seen the cable work wonders like that. I knew and old man here that had a small company way back from the fifties he installed gas stations. One of his 8N's he had a front blade and and auger on the rear. He had a pulley system he made to that followds the same lines as the Dear born tractor Jack and the light manure loader they had. hen the bit wouldnt go through asphault or the clay here he connected his cable and would raise the blade. I remember it as a kid in the eighties and saw his son use it a few years ago. A few years ago a friend came oer with a similar problem he waned down pressure so I let him use my shop I was busy at the other end of his tractor working on some backdrag rippers for his loader. he cut the toplink eye off and weled on a bracket out of pip to hold 2 foot carhauler cylinder in a verticle position. it was at the same length over al las the old original set up but when power was needed he could put alot of pressure on it. As for the box holding up Ive seen alot of cheapy phd's hung on the baqck of old 480 Case Landscape loaders with power down and push down till the wheels lifted off the ground. I imagine a smaller tractor wouldnt have a big problem with it.

A PHD is available with hydrualic down pressure, it is mounted
on the 3PL, the top link is fixed so the unit is only carried on the
3PL, it cannot be raised or lowered by it.
The gearbox & auger are mounted on the end of a frame that
pivots, this is controlled (up& down) by 12" or longer ram worked
from the tractor remotes, this supplying downward force.
I built PHD along these lines using a using the GB,PTO, etc
from a 1950s Promac 3PLD, bought a new auger & cutter,
It worked well.
Most 3PL PHD could be converted to this system

Just an FYI, you do not have to hit Enter at the end of every line when typing a reply.

Buy the down force kit. I usually advocate not buying implements that get little use but this is a safety issue. On a tractor with 25 horse power the torque output is 50 FT/LBS. The PTO gears this down from 3000 RPM to 500 RPM creating about 250 to 300 FT/LBS. The PHD then gears it down a further 3 to 1 ratio creating 750 to 900 FT/LBS of torque! That’s as much as a big diesel engine from a truck! Be careful with PHDs the torque is incredible and allot of injuries occur because of it. It's geared down from 3000 RPM to 100 RPM. Think what the torque is on a big full size tractor.

my suggestion....

return (or sell) your 3pt version and get one of these

who what where please.

Is that a Dansur hydraulic unit? One of those with a set of augers will run over 3 grand, IIRC.

i really have no idea what it is other than hydrolic PHD (random google pic)

they run an extra $800 or so (from what ive seen) over a 3pt phd, but if your serious about punching holes in the ground, they are the way to go.

One of the members has a Landpride unit mounted on a QA frame so it sits front and center on his FEL arms (instead of off the side of an arm or bucket)

They offer downforce, and more manuverablity to get into tight spots for those tricky hole placements.

youll need some front hydrolics or long lines to connect to a rear remote or a even rear PTO driven pump.
