I was given a Jacobsen 4 blade, 2 stroke mower and would like any information that is available.  It is self-propelled and that does not work.  Also where does the remote throttle get mounted.  I don't see anywhere on the handlebars where it was mounted.  Handlebars may have been changed.  Model 42169 with a Jacobsen 321 motor.

Might be just Set to run proper RPM and not really have a throttle if it is the old time ones I have seen in past.

Not this one.  There is a throttle cable, but no control handle on the end of the throttle cable.

Nope, not even close.  Mine is a 4 blade 21" rotary mower made in the mid 70's.

I am beginning to get an idea what happened to this mower.  I think the mower is a mix and match one.  The handlebars only have one small hole and I think that is for a clip on the cable for the rear wheel drive engagement.  There are no other holes for a throttle control although it had a throttle cable on it when I got it.  I think the plastic top over the engine is from another mower, maybe the one where the engine came from.  I got an extra, used engine in with a box of other parts.  No idea what is wrong with the engine.  It turns over without strange noises.  The handlebars must be from a mower with the throttle control right on the engine, which some had.  I had a 4 cycle that was setup that way.  So, I attached a throttle control lever and will mount it to the handle bars then run it and see if the drive works before I try to find a cable for the drive.

no that engine cover looks like it is the right one for that machine, I have had a few. 

that 4 blade unit will really power thru the heavy stuff, it's like a big flywheel with 4  blade tips on it.

Well I have a manual for that mower that shows the speed control on the engine cover.  I will scan it and post it later.

I think this top is what the mower had that the handlebars came off of.  I have an arrow drawn in the scan of the mower to show the speed control, which I also scanned and posted.  I think the handlebars are what has been changed and they are not drilled for the throttle control lever.  The two scans I have here are what the top would look like for the handlebars that are on mine.  Not unless the engine that came with it was the original and had a top like I have scanned.  Anyway I have a plan to make it work.

I am going to try it out for a time, then set it out for free.  It does seem to run good.  I repaired all the stripped out threaded holes and have to anchor the throttle cable lever.  The drive does not work.  The drive unit has two pins that wear down and I have enough projects as it is.  It is not old enough to fit in with my other stuff and it has too much of that dreaded PLASTIC.  After all we are collectors of old iron and not old plastic.

Though it's not to your liking I hope goes to someone who like older equipment and appreciates it ,  I think it's pretty cool .

For those who never saw the 4 blade setup used by Jacobsen.

 

Alc, It's not like that I don't like it because I understand they really mow great, it's that I have so many other things waiting to work on and room to store is very limited.  Plus there is possibly more Rototiller items I may acquire in the near future.  I agree it is a neat mower.  Years ago I bought one like this one but it had a B&S 4 cycle engine and single conventional mower blade.  


  • DougT and Alc have said thanks
