Allis 720 lives again

Recommended Posts


Last housing was ordered by Simplicity Mfg from Sundstrand was 2011, there is no old new stock to be found anywhere.

Previous owner towed Allis 720 damaging piston slippers and fixed swash plate surface inside the motor housing. After spending three months on the hunt decided to modify a more readily available motor housing.

The machine shop did a great job.

In the top picture the long nose housing on the left is the old damaged housing that Allis requires, one of the right hand side has been modified

Nicely done Gill!

You can now have the 720 designated to loader tractor & 9020 to snowblower tractor!

I know I have been pretty inthralled by some of your repair posts on these including the engines!

Thanks ShaunE.

We had a nice dump of snow today with more expected during the evening, so the 9020 gets a work out tomorrow. The single stage snow thrower works great, but I'm curious why the case guys modify their snow throwers with rubber paddles.

I found that for a light skiff of snow it helps to put the tractor into a higher gear so that your gathering more snow to throw.

The Allis 720 has a damaged rear wheel rim, the holes worn out from loose wheel nuts, it has the wide flotation tires and I expect that rim is expensive to replace. I'm going to have the Colony laser cut a pair of 6" on 6" center plates then replace both rim centers.

Both tires are loaded, fortunately I have an ARO pneumatic diaphragm pump to handle the fluids. Next on my wish list is the air / water valve adapter used to empty and refill the tires.


Jack Cobb has rims for sale in Classifieds.  https://simpletractors.com/classifieds/item/486-16-x-8-720-rear-ag-rims-no-tires/

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
