Ok so here is the project. I am going to build a trailer/hauler for my mid mount mower on my Kioti. The reason is because i have the mower there is no need to buy another. Since i have to remove the mounting hardware for the mower to mount the hardware for the back hoe and vice versa i want a way that to make it rear mount. Enters this idea. Now the way i am going to do this would allow me to use the mower either mid mount if i elect or rear mount by mounting it under this unit. The problem i have is the mower works on 2000 rpm and the rear of course is 540. So i will need a pully/belt drive system to get it up to speed. i can do this with either a 16" to 4" pully or a 12" to 3" or a 8" to 2". I perfer the 16" OPTION OVER ALL. I am having a tough time finding a 16 cast iron pully. I will settle for the 12" if neccissary. Can any one offer me any assistance on where i can find such a beast.
Need some things for a conversion

your Kioti uses a 2000 rpm mid PTO?!?!? most mid PTO's are 1000 and change
if so you only need a 8:4 pulley setup.
but youve got quite the project ahead of you..... if you look at my MMM deck

there is no real easy way to convert the current shaft drive gear box to a pulley drive system with a second? gear box for the rear PTO....
seems what you would need to do is fab up a 2" pulley that would fit on the 20? spline input on the MMM gearbox, then run that to a second pully above it, that is connected to a second gear box and or pillow block/shaft input for a driveshaft off the rear PTO....
at any rate, good luck with your project

Yeah i was supprised to but the lever on the tractor says 2000 and so does the users manual. My deck is very similar in set up to yours. I am planing on making it do the pto shaft on the mower will connect to a drive shaft just like it does on the tractor so that i will not have to mod the mower. Since i have time sometimes and like to engineer things this is right up my ally. Now if it will just all work once it comes together. I have the cylinder that i am going to use already and most of the metal tubing so. I will post the CAD Drawings as soon as i have completed them but i was hopeing to find the pully so i can design the bearing blocks accordingly. I dont like to devieat for the paper on my designs

Graingers has several 14" pulleys all in the $35. range.
3X942 is for 3/4" bore
3X943 1" bore
1L847 is 5/8" bore
3LC03 is 7/8" bore
Grainger.com is the site and they have most pulleys. I didn't look at all of them but found these 4. They also have other sizes so maybe you can get the ratio you need.

I'm planning the same kind of job. My thought has been to replace the 2100 rpm gearbox on my mower with an equivalent hydraulic motor that is feed from a 540 pump or a mid-mounted 2100 pump. I'm figuring on a 25hp demand / flowrate. This allows me to attach the mower deck to the loader arms and offset it to get under my trees and fences. Graingers and Surplus Hydraulics has all the stuff. Be sure to watch the direction of rotation in your plans, especially if the discharge chute is on the side....

I don't have a mid PTO on my tractor, so I'm talking out of ignorance. Is the PTO output at an angle to the tractor centerline? In the picture of the MM mower, it looks like the shaft is at a pretty good angle offset to the centerline ~30 degrees give or take?. Does the tractor PTO output align with that angle?
What I'm concerned about is that the rear PTO is parallel to the tractor centerline and I'd expect driving the U-joints through that kind of angular offset would ruin the driveshaft in short order. I must be missing something somewhere. Adapt to the offset through the stepup/overdrive gearing maybe?

Think the best solution is use a hydraulic motor, not sure if it will run off the rear hydraulics or not, mounting on the front is a neat idea, forestry have a device like a backhoe with a mower on for ditches

Now I am not an engineer, however I have seen other posts where fellas have used gear boxes to either increase or decrease the rpms coming out of the PTO. Mount one of them to the rear of your assembly and connect the MMM shaft directly to it (as you would on the tractor). Then get a long PTO shaft from the tractor PTO to the gear box.

ive been looking for one of them to. I havent found what i need yet though. I ned one that will step up the ratio 1:3.7. Im still loking for parts so maybe i will find that. I have found most of the pulley stuff that i need. So hopefully i will be able to start here real soon on this. I have got to finish the plans first though.
