Rebuild Troybuilt Bronco

The tiller I brag about finally gave up the ghost and blew its engine. Dad said he was running it and he heard a boom and it quit instantly. I want to save the Kohler that is on
it if I can but I am thinking if it threw a rod or something along those lines that it may be toast. I could buy a new engine and bolt it up but dad wants a Briggs or better
engine. I'm sure some of you have rebuilt/repowered these. Any suggestions?
 
I bought a bigger Troybilt with a Kohler that someone had run low on oil & it seized up. Fortunately there was no other damage inside so my son cleaned the aluminum off the crankshaft, replaced the rod & some gaskets & it is as good as new.
 
If it's a Kohler Courage single, they crack their blocks and it's not repairable from what I've heard. Correct me if I'm wrong. I guess you've gotta be pretty courageous to own one of those...
 
My neighbor had a similar problem with his Troybuilt. Found an engine on Jacks Small Engines with the reversing shaft and bolted it right on.
 
I wanted a flathead Briggs for my Snapper rear engine rider. I found one on eBay that had few hours and got it for $75. That was hundreds of hours ago and it has been excellent. If dad's willing to spend the dollars then look for a NOS one on eBay. If not find a seller with good feedback. You can't go wrong with those old L head Briggs. I believe the Bronco came with a five horse Briggs flathead as one engine option.
 
If it's a K series Kohler (like say a K181) or a Kohler Magnum you'll probably be able to rebuild it. If you use genuine Kohler parts it'll cost you more to rebuild than a new Briggs & Stratton engine will and probably cost about the same as a new Honda engine (if you shop carefully for the Honda) . If you use knock -off parts it'll be reasonable cost but I'm not to sure about the quality
 
K 161 T Kohler is a perfect match for this tiller. I think you mentioned the motor was going to need a rebuild before. Far better to repair them before catastrophic failure.

The K 161 T was specific to this tiller. Hopefully its re-buildable as its a good match, power, torque and its weight being cast iron. The other thing is they start on one pull, and are easy to work on and get parts for.
 
I don't know if by Bronco you mean Horse. I have a Troybilt Horse that had a Kohler Engine. When it quit I put a Predator engine from Harbor Freight on it. Only $99, can't rebuild yours for that.
 

Another Kohler is your best option. Briggs quality ain't what it used to be. I refuse to even look at a lawnmower or garden tiller if it has a Briggs engine.
 
I bought one of those HF Predator engines to put on my 40 year old Troy Bilt Horse. Bolted right up and works great. The only thing is that all the rubber parts have already rotted off after two years and I'm having to replace fuel lines and so forth. Still happy with the motor though.
 
Does that tiller require an engine with a gearbox and two outputs or is it just a basic engine? Consider how many hours you put on the tiller in a year before buying an expensive premium engine. For most people they are very very low hour machines. Almost any engine can last 20 plus years in that kind of service with just basic maintenance.
 
I think by Bronco he meant Bronco. There's a Horse, and a Bronco and a Pony. They all sound equine, but they're not the same.
 
Which ever is the biggest one they made in the mid 70's is the one we have. I said Bronco but Horse might be right. It is a great machine and I kind of want to rebuild it for my dad or repower it for him for Christmas or maybe his birthday.
