I've got several plows, three set up for a sleeve hitch, one for a three point. The 10" is a standard Brinly plow, older but in good shape. The second one I believe is from a Jacobsen or Ford, its basically identical to the Brinly but with a 12" plow share and a longer arm, which I cut and welded on a standard sleeve hitch bracket, the third is a modified Farmall plow, it measures 12" but the plow share is larger all around. Someone gave me the Farmall plow since the frame of it was bent or modified by someone else, I cut it and was going to convert it to a three point but figured I'd try it as a sleeve hitch plow and it worked.
I don't try to bury that one very deep unless I know the soil is already loose enough. The 12" Brinly/Jake is fine so long as I'm not busting through new ground for the first time. The biggest problem with either 12" is that the machine bottoms and can get stuck if the soil is too soft or wet. I've had to drag out a tow chain and another tractor twice so far. I also don't like how much dirt gets shoved up over the transaxle and onto the belts. I thought about making up some sort of skid plate or deflector but I think that may only help it hold dirt in the frame.
I put the 26" tires along side a pair of Titan turf tires I had here and the 26" ag tires on the JD rims aren't more than 1.5" in diameter large and the width is hardly noticable. Maybe if they were mounted on full 12" rims they'd be a bit wider but as they sit I think their doable. I'm not sure which series Carlisle tires they are, they have more bars than most and the bars are narrower. One thing for sure, they're heavy. I was just going to scuff the rims up and give them a shot of off white to match the AC and give them a shot. I doubt the gear ratio change will be noticable. My thinking is that the one field I plow keeps turning up a lot of junk, like old bottles, car parts, and other various farm equipment parts. (the first time through I unearthed an old hit and miss motor It stopped me dead, but the plow got under and around it and lifted it up enough that I could get a strap around it and pull it free.)
The JD wheels are sort of freebies, so if they got torn up in that field it won't hurt so bad. I'm also thinking that the extra weight and traction may help it pull the larger plow better, or at least faster. If not maybe they'll go on the 916, which also will never see a mower deck. That one will most likely only plow snow and drag a mid grader blade or rear tiller. If I had a 7116 with a gear trans it would be ideal, I'm not sure the hydro is the way to go for plowing or not. It will come in handy snow plowing though I suppose. I like the hydraulics that come with the hydro trans models.
The 416S is a well used machine, its not pretty by any means, when i got it the hood was smashed down from the last owner felling a tree onto it. He hammered it out enough to open and close and rewelded the hinge area and all was fine. The original Kohler was replaced with a rebuilt Briggs 16hp right before I got it, the subsequent wiring issues were why I got it cheap with a lot of new parts. The seat pan is cracked front and back and rusted through pretty bad under the seat, the front spindles are worn and have been welded up and ground down to hold the wheels tight again, the hood holds about a gallon or more of water when it rains from the belly in the middle where its smached down on one side, and the entire machine lists to the left for some reason, most likely from the tree that landed on it. Most of the lean is in the dash tower, its rusted out beneath the battery and its tweaked over to the right a good bit. I've got a super clean 410 rolling chassis that I've considered swapping everything over too but I've not had the time to tear it down so long as it still gets the job done.
I strongly prefer the steering on the 416 over the open gears on the SImplicity too. I've thought about putting a straight three speed rear end into the 410 chassis and using the Briggs 16hp on that instead, but the fact that my 916 has hydraulic lift has kept me working on that in hopes of having it up and running properly by winter to plow snow. Hydraulic lift will be a big improvement over the manual lift on the 416S.
If I get them painted and mounted up I'll snap a few pics.
