While I was there I saw a tractor there that was restored buy a guy in Hillsboro Ohio his name was Tom. It was an Allis Chalmers 620 it was perfect. I fell in love with this tractor. I wanted to get an ingersoll 4020 until I saw this beast it has it hands down over the ingersoll. I must have a 620 or a 720 allis anyone who has any info on them please share. What is the is the difference between them what's available in attachments. I must know lol I can't sleep for thinking about where to get one to rebuild and restore.

Tim, the Powermax tractors (and their Allis counterparts) are very popular machines.  There were improvements in later models and options available that drive higher values.  Generally, a decent, running 4040 Powermax or Allis 620 can be had in the $1500 range.  All have a 2 speed rear end, most have 3pt hitch, but few have a working rear PTO (2000rpm).  Attachments such as deck, dozer, blower are fairly common, and run $250-600 each, depending on condition.  Other popular and harder to find attachments can run higher...Sweepster, Snow cab (hard and soft), 48" tiller, etc.  Nonpowered Cat0 and Cat1 attachments for the 3pt are very common, and reasonably priced locally.

 

Auxiliary hydraulics, rear PTO, engine upgrades all drive value higher.  Onans are typically thought of as expensive to fix, and many of these tractors now use a Briggs Vanguard or Honda Vtwin.  Later models have an upgraded front axle setup that is favored vs the earlier type.  Loaders can be found for folks with a decent budget.  These tractors do lack power steering, whoever, which is unfortunate.

 

VS a 4020, attachments are probably harder to find, but around the same price.  The 4020 will be a bit smaller, but arguably as capable.  The hydrive system is tough to beat.

I have a 620 and 720,i personally like the decal on 620 better,differences I know are decal on hood,720 has a safety lockout on 3 speed shifter,front steering castings bigger on 720 although I argue they are any better how would u ever break it...axles front end identical,also some 720's where called (specials) a lower cost version where 3pt rear pto hour meter where a option,not everyone needed this,also I noticed on specials you got a 2 u shaped springs under seat versus adjustable version on a normal one were u had a lever to slide back and forth,electric clutches are different also,one better than other,no, not in my opinion,black grill on 720 white on 620,they are plentiful around my area and into Minnesota there are always on craigslist,nice one on there now,far as locking diff,u don't need one ,both wheels grab hard,i know! only flaws I see r no power steering and I think the onans are underpowered for the size of them,as far as prices,you wont find one out here for 1,500,there usually 2500-5,000 for nice ones

We bought a Simplicity 4041 which is the same as the A/C 720 with the 19.9 HP CCKB Onan. It is a horse of a tractor.

More then likely it's a bad coil and or points/condenser. Also make sure you have 12vts to the coil, maybe a bad connection at the ignition switch or at the engine plug in down by the starter where the wiring harness plugs in to the engine wiring. I have had the issues with our 4041 SIM.. I have an ignition switch that you can turn past the point where the coil feed doesn't send power to the coil, maybe that is your issue.

 

There is a thread about it here,
