In the process of repowering a SS/16 with a 13hp Harbor Freight Predator engine
kinda started out with a parts tractor and trying to make it run again why ? I
don't know but anyway I have been posting in Sears, Craftsman Tractor Forum and
have got some great advice from fellow members, but now I am doing the repower
and by reading threw this forum I see that there is some good information here
and wondering if anyone has done a 13hp predator repower ?

Well you picked a good one to repower without having to cut up the grill and mod the air box and muffler.Should be plenty of room.


Other sears suburbans would of been a little tight to fit one in there because they are a Longer block than the older single cylinder engines and then you would have to cut a bit of the battery box/gas tank mount out.

And you don't have to worry about rigging up something to hold the Clutch mec on that one.


Harbor Freight wants a $359 for them.



But you can get the same engine on ebay for alot cheaper.$270



And if you don't mind pull starting Here's a good deal.$170

Harbor Freight is cheaper than that, watch sales. If you put your name in for sale flyers, you get many in email and much cheaper than reg store. Also, in magazines they put a couple pages in and at times have this one or the 6.5 listed. $99 for that one, can't recall the other, know less than $200 anyway. Thing about them is all controls are on the engine on a plate. Key and all. I've seen guys use them, leave the key there and choke, then start off tractor, get on once running. They usually want a cable op throttle tho, going back to dash or op area. Probly easy to do that??

Just curious, why the repower?

Broken rod, missing parts, ect?

Sorry, I missed the thread:)

EricFromPa - your right there should be plenty of room if that 16hp ONAN fit
surely that 13hp will, I looked at them at harbor freight it didn't look as big
and yeah the clutch don't look to be a problem either, I guess I kinda lucked out
and started with one that hopefully won't be to hard to repower and I am glad or
I would have had to put it away for later on or even used it for parts for
another suburban and that would have been the smart thing to do but I never
been accused of that and look at all the fun I would have missed.

glgrumpy - checked the price at harbor freight they are $359.99 for the 13hp
#60340 the 6.5hp and the 8hp can be bought real reasonable, I have a 25% off
coupon good for Sept 5th only, that brings it down to 269.99 + 6% tax = $286.19
its fully self contained gas and oil and its running on its own, like you said
relocate the throttle on my soon to be homemade dash unless I brake down and buy
one, I could even relocate the key switch and a choke later, I think I will rig
up a kill switch on the dash in case my test drive goes terribly wrong, I will
sign up on that mailing list asap.

stiemmy - doing the repower cause my 16hp onan engine was locked up its not now
had about 1/2 gallon water rust and some kinda crude in it plus a lot of parts
missing needed to make it run and if I had a for sure good engine I would got
what parts I needed to get it running would much rather have the onan engine I
might get it going later on its unseized got the valves working freely got it
full of transmission fluid got the carburetor bolts loose save it for later,
the repower is my cheapest way to go so I can get it running right now, I am
trying not to put more into it than it would ever be worth and I am sure I will
and may already have when I buy the 13hp engine

crittersf1 - I have been reading a lot of reviews and seems like most everyone
has had good luck with them especially the 6.5hp and the larger ones also,
I remember back in the day they had a lot of trouble with the predator engines
they must be doing something different now there is a lot of people using them
even racing them.

I put a 13 HP predator in my Massey several years ago.  Only problem so far is the fuel filter had to be replace - in  tank type.  Also,I wasn't happy with the air filter -flat foam oiled - but there are alternatives out there now.


here is the thread, and the date tells me its been over 4 years.  This is my main mowing tractor, so I've put a lot of hours on it over that time.
