I think I have about 6 1 arm loaders on tractors right now, and one more waiting to go on a tractor.
I have both the 711 model ( most of em ).. and 1 722. all are 1 arms.. Most of mine are trip models, with 2 of them hyd dump.
the breakout force is 3000# and they can lift 1300# to full height in about 11 seconds with the oem pump.
they were designed to work fine at the 4gpm / 2250 psi rate the 00/01 fords had. they are not speed demons.. but they work.
I used to routinely move up to 1000# 4x5 hay round bales with mine. in fact.. from 2004 till the beginning of 2011 i ONLY had 1-arm laoders to do all my hay moving. wasn't until early this year I got a 2 arm loader.
let me know if ya got any specific questions. I have both the v1 and v2 manuals, the parts manual and attachment kit manual, plus an advertisement brochure.
the 850 in the pictures, has since had a 3pt backhoe added, thus making it a light duty TLB. very nice to have a hyd loader and a backhoe.
i've seen conversions to trip bucket models adding a 2' or so cyl between a lever elded to the bucket and attached to the front support boom, then you remove the trip latch and release mechanism and plub the dump cyl to a da spool, while the lift cyl is on a SA spool. works ok, though does not auto level like the scissor parallel bar setup of the regular hyd dump model.
some have dirt buckets.. some have maneuer tines with a material plate.
i have both the cable pull trip style and the rod pull trip style. both 3 cyl and 4 yl models, plus a rear bracket set that let me put one on my NAA. required removing the steering box and adding a bracing plate underneath it plus a special trans flange bracket.
