So you need 16" to 20" cylinders?

 

Not checked geometry of all that yet, but being the outfit won't be that heavy, I'd think I can use shorter link arms off the riggers & do fine with much shorter cylinders....wouldn't you think?

I think so, the shorter the better in my opinion.

It's hard to describe, but the pinned down riggers go straight back.  The tractor tires will be behind the cross frame of the hoe.  Oh well, here's a crude diagram on the pic.  I will set the down riggers to hinge at 45 degree or so.  This will put the cylinder (blue) underneath.  The riggers will only need to come up level to frame for transport mode, so the stroke wouldn't need to be more than 12" or less, depending on the length of my link arm.  Pink & green being pin points.

Oops, looked at rotation wrong.  I will need to drive the pump off the crankshaft end of engine (front of hood next to grill), or get another pump, which I hate to spend more money.  I am hoping I can change rotation of the pump I have, as I need the space up front for the battery and an alternator, as my synchrowave stator is fried.

Today I fired up the old 720 & drove it to the shop.  I swapped out the rear wheel assemblies with the WIDE ags I had on the Allis 620.  May be selling the 620 soon, so put the original "zig-zag" tires back on the 620.  The super wide ags will be great for the 620 if I ever get to make it into a devoted backhoe unit.

I'd have to say most common was mowing with their 60" decks. Most have the wide Good Year flotation tires like on mine, and they were mainly for mowing. The other option was 16x8 rims with ag tires & 12" rims with tri-ribs up front. They were for garden plowing & the like. When the time comes that I can afford, I would like to put 29x12.50x15 ags on the rear of this. These may be absolutely too wide to plow as they would nowhere near squeeze into even a 12" plow furrow. These flotations are 31x15.50x15.

I have a 72 in deck , with ag. tires on mine. It was used for landscaping on large apt. bldgings. when I found it in a barn, it took me 3 years to get it from a friend. I just put chains on in winter ,it goes great for plowing snow. Does anyone know how to solve the kik back on the steering ?

Got her all pressured up with oil, then even fired her up off carb spray. Then no more time to piddle with it. Then while sitting eating lunch, it came to me that I forgot to align the pin into the governor, so the flywheel & timing cover have to come back off! Doesn't pay to get in a hurry! :wallbanging::wallbanging: :wallbanging::wallbanging:

I'm a retired mechanic  "chev" , I have often woke in the morning with the answer to a problem. thanks to the sub conscious !
