jsoluna 84 #1 Posted August 1 Hello all, First time Wheel Horse owner. Have worked on them for customers at our shop for several years, but there are very few of them immediately local so we only see a handful every year. We mostly work on the 300/400 series. We see mostly Cubs here, as there is a dealer down the road from us. Excited to have received this one. It was a single owner machine, bought new back in '71. It was used every year by a friend's grandfather until somewhat recently (~5ish years). This thread will be updated with data and posts from our YouTube channel as we go through the revival process. It needs a ton of work, but last week we were able to get it running, driving, and mowing again. The biggest hurdle there was in needing to rewind the electric PTO clutch. First time attempting a rewind/repotting. It went really well and we have about 5 hours of heavy mowing on the machine since the repairs. Looking forward to learning more and being able to share the experience. Revivals are what started our YouTube channel and continue to be the source of joy that keeps things interesting and fun.

jsoluna 84 #2 Posted August 1 (edited) Brought the unit over to a property that I maintain for a friend of mine. Figure he'd get a kick out of it, and he did! Like the Tecumseh smoke haze? 🧐 Plans in the works for an engine swap with a Command CH13 single, keeping everything as original as possible. No sheet metal movement or cutting.

wallfish 18,242 #3 Posted August 1 Nice. Looking forward to the progress on it. That tractor looks to be garaged most of it's life so that paint should clean up but pics don't always tell the whole story either. 2 Share this post Link to post Share on other sites

Definitely not touching any of the sheetmetal wiith anything other than some mineral oil and a Scotch Brite pad. Haven't even touched it with a pressure washer yet.

jsoluna 84 #9 Posted August 5 Mowed yesterday with it and put it under a good heavy load. Amazing little machine but man, that poor Tecumseh is ready to go. Got the donor engine fired up and test ran it. Runs Amazon, seems to be very low hours. Crankshaft height and diameter are different, crankshaft length is almost identical. Going to start the mockup process and pull the Tecumseh soon. I realized this unit has the 10-pinion LSD diff. Probably not at all limited slip anymore, given that it has been run low on fluid for decades. Are these 10 pinion units a reason for concern at all if not maintained? 1 Share this post Link to post Share on other sites

The actual limited slip piece is literally a metal ring that slides in between all the pinion gears. It is of course a wear item. My best suggestion I think would be to get a rare earth magnet and attach it to the bottom of the transmission near the drain plug. Run. Flush. Repeat. Hopefully that will get whatever metal filings are floating around in there, out. 1 Share this post Link to post Share on other sites

Hopefully that will get whatever metal filings are floating around in there, out. Currently doing a flush similar to what you suggest, using ATF. The neodymium magnet is a good idea. I'll chuck one of those on there. Edited August 5 by jsoluna 1 Share this post Link to post Share on other sites

I've determined that if I keep the crank centerline and fore-aft location the same, the Command will clear by about 1/4" between the hood and the valve cover. This will require a custom mounting plate, but no big deal. There should be ample room to change the oil filter, there is clear access to the oil drains and the air filter assembly. Need to get it fully mocked up to see how it interacts with the drive belt guide and battery tray area. The crankshaft diameter difference (Command is 1.000" and the Tecumseh is 1.125") should be easily dealt with a custom crankshaft sleeve and key. I'll get some pics and measurements as we move forward. Excited to keep it as original as possible. I believe the original style control cables, electrical system (although we will rewire it because it is really pooched) fuel system, and muffler will all swap over to keep it as original as possible. I've owned a lot of the single cylinder Commands, and they are a really fantastic little engine. Edited August 5 by jsoluna 2 Share this post Link to post Share on other sites

No problem. WH used both 1 and 1-1/8 shaft electric PTOs. Your rewound coil should fit the 1 " pulley set I have 1" pulleys if you want one.

I've already ordered a crankshaft adapter sleeve and key, but if it doesn't work out an 1" pulley set would be great Edited August 5 by jsoluna 1 Share this post Link to post Share on other sites
ebinmaine 72,988 #16 Posted August 5 @jsoluna Check the solidity of your existing muffler. Those are tough to find in good shape. 1 Share this post Link to post Share on other sites

I just looked it over the other day, as it had been taken off at some point and then re-attached and improperly clamped, causing it to blow exhaust onto the air filter. It's a loud muffler in my opinion. The baffles may not be great inside. The outer shell is is really good shape though. 1 Share this post Link to post Share on other sites

AlexR 2,026 #20 Posted August 10 It's cool to see the remnants of the hood stripe on there. I'm planning on putting one on the Raider 14 I am redoing. Adds about 5hp 2 Share this post Link to post Share on other sites

jsoluna 84 #22 Posted August 11 More reference pics. The sheave for the PTO could move back a hair and actually might track even better that way. The total crankshaft length on the Command, according to the data sheet is about 1/4" shorter than the HH100, but I'm thinking that might actually be fine. Excited for the mockup of the engine soon. All the calcs and measurements check out, physical placement is the next step. 2 Share this post Link to post Share on other sites
