Yeah, that's a first.

Still a bit perplexed on the tensioner design for the PTO setup. I really would like an electric clutch, but spending $200-300 on one is a bit crazy. So I was thinking some sort of foot actuated tensioner? Like something mounted on a cam and when pushed forward it would snap into a position to provide tension, and when pressed back would snap into a position of no tension.

Am I just crazy?

Damn.

I don't know how I didn't stumble upon this before... The bolens deck and pto assembly I have will require the engine to be rotated 180 from stock Panzer position. So now the dilemma is do I flip the frame so the rear end turns the correct way, or do I find some sort of 1:1 reverse gearbox?

Ideas?

I guess I could rig up some kind of idler sprocket setup for the rear drive and spin the rear backwards?

Flipping the rear may be an option. But everything is set up a certain way so it would require grinding off the welds and re-welding to frame and brackets to keep everything else the same. or if you just do a straight flip, then the engine mounts low and the differential becomes higher. Doable, but odd.

Can you turn the deck pto all the way around and therefore the engine rotation would then be correct???

I'm thinking the idler sprocket idea will work. I will just drive the chain from the outside instead of the inside.

I get what you mean. The only thing I'd worry about with driving off an idler is the contact are between the chain and the sprocket. If it's an idler off a straight chain run, then it's going to need to be real tight. What about using a belt instead in a bit of a serpentine arrangement? A belt would also slip if you hit a stump or whatever on the mower.

I was thinking I would position the idler pulley so that I would get 1/4 wrap on the drive sprocket.

The pulley size on the rear end would have to be similar to the sprocket size, along with the pulley on the trans... think there's enough room to twist a belt? Hmm...

Actually you know what.. I could just twist the input belt on the transmission and keep the stock chain setup in the rear.

Updated engine pictures. I had to reverse the engine around for PTO reasons. I guess it also makes the tensioner setup easier to fabricate too.

I'm going to mount the tranny on the right side of the engine (from the driver position) and it will flush up with the right outside frame tube. This should give me enough room to figure 8 the belt to keep the drive direction correct.

I'm going to cut a piece of 10" x 2.5" x 1/4" C-Channel today at work.. Hopefully I'll get some time this weekend to cut out the old motor plate and mock up this new one. The motor plate is going to be a catch all of sorts. Not only will it support the engine it will support the front of the tranny, PTO shaft assembly, tensioner brackets, steering tie rod pivot shaft/bracket, and steering shaft/swing arm.

Fabbed up some mockup pulleys quick during my lunch hour. They are very close to the dimensions of the actual. I'm going to use these to figure out PTO/Tranny final placement. Also saves me money if for some reason my size selection doesn't work out.

Dang! Your fashioning Panzer style pulleys from scratch? When you get that working right, spin me a pair.

Ha! Actually was a good thing I did... My engine shaft wasn't 1-1/8 like I thought... It is 1-1/2. Lol. Not sure how I got that wrong. Also the input on the T-92 is 7/8 not 3/4?

Not much has happened lately. Too much life stuff going on to get time/money. I did rearrange my 2 sheds on the property and moved the Panzer into the shed that has power & tools to work on it.

Need to get one of those propane heater heads so I can stay warm while messing around.

The pulleys and bearings I need to rework the steering/driveline are part of a Christmas gift this year. I'm still working on getting the steel cut and modified so I can work on the engine outside of the tractor.

Other plans are to make some plywood temp wheels for the rear end so I can free up the rear wheels for sand blasting.
