I used this to repower a 2006ish bobcat ZT227 61" commercial zero turn, it has plenty of power and gets the job done and more importantly it fits under the bobcats really low hydraulic oil cooler. A few things I had to do to make it work: -The mower originally had a Kohler Command Pro 27hp that had thrown a rod, the original motor had a 1 1/8 shaft that was 4 inches long. The new engine has a longer shaft but that is OK because when you stack the pulley on top of the assembled PTO you can measure down inside and you get 4 3/8" and since the shaft length on the motor is 4-5/16" which is shorter by 1/16" so it will tighten down OK, The only thing I had to do was add 3 big washers to the bolt that tightens down the PTO since it was a shoulder bolt it was bottoming out before it tightened the pto/pulley down, or you could just buy a new bolt with less of a shoulder.... - Rewire the starter engagement, the old kohler engine has a built in starter solenoid, you will need to wire in a briggs style starter solenoid, on the new solenoid; a. one small lead goes to ground b. one small lead goes to the wire that is switched hot when the ignition switch is turned to start (yellow on my bobcat harness) c. one big lead goes to the starter d. the other big lead goes to the battery wire and on that same lug the other red smaller wire from the bobcat harness needs to connect there to power all the relays and stuff on the mower to a constant 12v. - On the briggs it only uses 3 wires on the harness: a. the black is the kill switch (white on bobcat harness) b. the red one is from the alternator to charge the battery (Purple on bobcat harness) c. the gray wire goes to the fuel solenoid (This one is interesting, using my tester this SHOULD go to the green wire on the bobcat harness, but in my case I was only getting 10.5v to this wire which would NOT open the fuel solenoid so I was not getting any gas to the carb and the engine would not kick over, so I instead hooked the gray wire from the briggs harness and tapped into to the Orange wire coming directly off of the ignition switch which are hot when the ignition is turned ON and that worked for me) - The black wires on the bobcat harness all go to ground - The original muffler on the bobcat would not line up and was too close to the engine control cables and the ports were out of alignment slightly, I could have probably cut/welded or bent it to work but mine was rusty anyway and I opted to buy briggs part # 696226 from amazon which worked fine on the bobcat and is nice and quiet - (optional) for the future buy this to make oil changes easy, it is way easier to put on now with no oil in the motor....

This 27hp engine has been an excellent replacement for an old (650hr) 26hp 440000 series Briggs on my SCAG mower and I currently have 200+ hours on the new engine. Compatibility - The mounting holes are identical, the muffler mounts are the same as the old engine so I was able to remount and keep using the old muffler. All of the wiring harness links could be reused without any modifications as well. Note that the more powerful engine did make the mower more responsive and this seems to put more stress on the hydraulic steering system so be sure to keep an eye on the fluid temperature so as to not overheat. Soft Chinese hi-lift blades take a beating and fatigue quickly with the extra power. With the new air filtration system I was hoping for less maintenance, but just had to get into the carb at 60hrs.

This engine was a direct bolt-in replacement for the Kohler Courage SV735-0016 engine in my Craftsman 917.289470 garden tractor. My tractor was in fine condition, except for the major birth defect it has had its whole life... a Kohler engine. I know now that the Kohler engine has always been weak, but the starter started clanking and clunking, and the mower had grown so weak that it couldn't mow up a hill anymore. You could either mow, or go up a hill, but not at the same time. A local respectable small engine guy said the engine was only running on one cylinder and that it would cost just south of $2 grand to rebuild it. He offered me $300 to buy the little tractor, planning on either rebuilding the engine and selling it, or replacing the engine himself. I'm handy, so I took it home and ordered this engine. The engine swap was a direct, bolt in replacement. The old muffler fit fine, the shaft pullies slipped right on and the electrical harness was a direct plug-in fit. I didn't have to customize a thing. The only minor difference was that the throttle and choke cables needed to go down the left side of the engine instead of the right side. They were long enough to just move them from the right side to the left side. In fact the throttle cable was a little too long and I had to creatively tuck it in under the dashboard. The main key is to make sure the shaft diameter and length is the same. Most of these garden tractors are made by the same company so the engines all have the same specs. I'm sure your replacement will be straightforward, but you may have to buy a new muffler. I was lucky and my old muffler fit fine. The trick is to bolt the exhaust pipes onto the engine loosely, then mount the muffler onto them before tightening them up. Regarding the muffler, the tractor is much quieter now even with the old muffler that was much louder on the old Kohler engine. That old Kohler engine was garbage from the git-go and I'm glad it's gone. My little garden tractor has a new soul and a desire to eat grass like it's never had before. So rather than selling it for $300 and then spending ~$3500 on a new one, I'm glad I took a chance on a new engine for ~$1000 and spent the two hours to swap them out.

I bought this motor to repower a Bad Boy 60" zero turn that origionally had a Kohler 25hp. New Motor came on time and undamaged. Here are the most important parts of this swap that I couldn't find online and had to figure out. 1) the electrical connector is the same between the 2 engines. 2) the crankshaft is the correct length and diameter. 3) the choke cable hooks up on the upper arm just under the air cleaner and the throttle hooks on the bottom and actually hooks onto the governor linkage. (this was weird to me but it works) and the throttle works backwards ( fast is slow, slow is fast). 4) the exhaust muffler is technically different. I made mine work because the correct one was not available. If it had been I would have replaced it with the right one. 5) run your mounting bolts in before you put the motor on so the threads are already tapped. Then use lock-tight to keep the bolts from vibrating loose. All in all this was a very easy swap and took less than a day. I will say that it didn't want to start right away. After cranking on and off for about 10 min and making sure I had spark and the fuel solenoid was working I gave it a few shots of starting fluid and it took right off. Runs smooth and more power/torque than the old motor.

So far, I have no complaints. Bought this engine 3 months ago to replace my last Briggs (22 horse OVH, twin) which lasted 13 years. Sounds like a lot, but the one before that made it 23 years and was still running when I gave up on the tractor for difficulty in getting parts and bought the current one. Did my homework. This engine was the most reasonable considering cost, power, ease of replacement fit, age of the tractor and reviews concerning failure problems unique to the 27 hp engine. The engine came via Amazon Prime. The price was competitive. The manual that came with the engine was adequate, but could have provided more installation diagrams and maintenance related information. The replacement, except for the recommended muffler, was a perfect bolt on match. I was concerned about the electrical harness, but the connectors were a perfect match also. Started right up and been running fine since. Time will tell how this one holds up.

Was a great engine until helene devastated my land and took my Dixie Chopper what was in a huge storage building.

This was not a recommended engine for my mower. It is not a direct replacement as the shaft is longer. it is also slightly larger physical dimensions, but went in easily. only change was a 1/2" spacer between my drive pulley and the cutting deck pulley, and a 1" lift of the hydraulic oil reservoir. no holes to drill. lots of power, very happy.
