I might have a tranny mount pump if you're interested.  No idea what it fits or what it's worth, but everytime I mention hydraulics around one of my customers, he tries to sell me his pump.

looks interesting Maurice!  So how slow will it go?  ;D   Have you driven it yet to see how the ratios work out?



If you put both tranny's in reverse does it go forward?  Actually you probably wouldn't want to ever put the front tranny in reverse because the rear tranny isn't designed for reverse direction input?  Or does it even matter?


You can upload photos to a DTS album and post them from there just like from photobucket, or upload them right to the post.  I actually like to use the DTS album then if photobucket changes something it doesn't leave broken links in the posts.

Boostinjdn, I'm interested, I think I see an email link - I'll try after I post this.

Engineer, How slow? On paper I've calculated with 2 trannys and transfer case, I can go 183:1 in forward, and 144:1 in reverse.  As I understand it does not matter if a tranny input is forward or reverse.  Altho' I have been warned that I may not want to use double reverse.  Yes, double reverse is forward.  The way it was explained to me is that as the gearing slows down the speed, the torque multiplies.  The torque could be enough to break the reverse gear out of the tranny casting.  I wondered that if the wheels slip wouldn't the drive train be safe?  But was told even if wheels spin it could still damage something.

Yes I have driven it!  Feels fun, tho' I'm still working thru some stuff. For instance I found I did not make it easy to reach the front shifter while pushing the clutch!  And when the front tranny is in 1, 2, or 3, then reverse gear from the 2nd tranny is verrrry slow!  slow is good if I'm wanting to be careful, but what if I'm wanting speed and fun? ;D

For a hydraulic pump for the mower, would a second-hand truck (big rig) power steering pump put out enough flow? Belt driven off the front of the motor, clutching wouldn't kill your hydraulics.

I have to take some stuff to the guy tommarrow.  Maybe I can pick up the pump and get some numbers off of it.  It's in one of his out buildings and might be snowed in.  I'll find out tommarrow.

Boostinjdm, getting some numbers might help me figure if it might work.  Not all tranny gears are the same, as I'm finding out.

Chrishallet83, I don't know anything about big rigs.  Any idea what pressure and flow they have?  Average cars/trucks are about 500psi, and low flow.  Some have used power steering pumps to power small projects.

What I'm learning about hydraulics is that about 1 gpm x 1500psi = 1 HP. The mower mfr says it needs 25HP at the mower deck to cut properly.  It costs some mechanical efficiency to convert engine power to hydraulics, about 15%.

As you can see from Spec's pictures and posts, he knows more about hydraulics than I! I've only built a small backhoe and this trucktor is my 2nd hydraulic project!

I was thinking about your shifter problem M.
I can prolly bend you up one to reach back to where you need it to be

I was thinking along those lines too.  There's so much still to do on it, the shifter is a bit lower on the list.  In fact as I was driving it today, the power steering hose blew! rofl

Just a suggestion. Or maybe just a thought really. If you could score a pair of high fear ring and pinions you could benefit from the much larger diameter/stronger pinion . With that much gear reduction I'd thinkk beefing up anything you can in the driveline would be good.
