Dedicated 782
 

I picked up this 782 last year pretty cheap. Dad came up with the idea of using it to tow around our 15 gallon trailer sprayer. I went one further and decided to permanently mount the sprayer to the lawn mower. We go in way too many tight, cramped, and otherwise unfriendly places to bother towing a sprayer. I don't like the factory booms so I picked up what I need last night from TSC to switch it over to 2 or 3 flat fan nozzles, I'll replace the boom itself with angle iron. So far I "trimmed" around the houses and farm with 60 gallons of Roundup. With all the rain we have been getting there are a lot of weeds to deal with this year. I got plenty more to spray still. Working on a engine issue as well. Machine is very stable, if you get crazy/stupid you can make the front end pop a wheelie with a full tank. If I ever find that becomes an issue I'll add weights (or a blade) to the front. FWIW, our land is NOT flat. I crossed a couple ditches yesterday where the front end went to full travel and still lifted a wheel off the ground. No plans on making this "pretty", this is all about working and getting it done. I ain't got time to worry about driving through mudholes or getting scratched by tree limbs.

Looks good John, gonna be a handy piece of equipment.
Always wanted a small front mounted quick attach boom,for poking yer nose in areas that are hard to get at,
or spraying a gravel driveway where you are not looking back over your shoulder all the time.:beerchug:

that's a nice rig, my pops been wanting one for sometime just like that to spray all his fences. The only caveat is it has to be an IH 82 series, he's not interested in the yellow and white, even though he's got a 154 cub lo boy. He's tried unsuccessfully to buy one of mine. I keep looking wherever I go to find one but I hate to part with the red ones when I buy one and add to the fleet, I've even brought home a few red ones that were CCC and it was a no go for him when I show him, cant say as I blame him. Very nice useful machine there, I'm assuming its hooked up to a sleeve hitch?

John,

I have had that idea for a while now.. just never got around to doing it... glad to know it works!:beerchug:

The flat fan nozzles work well... way better than having a boom to deal with!

This pre built setup from Fimco works very well.. I have a friend that has one on a small 3 point sprayer.. fully adjustable pattern and you can cut individual nozzles off for spraying only one side.. works great around ditches and fence rows!

This is a red Cadet. The PO wanted it yellow, so he had it repainted. I bought it off a guy that just buys/resells stuff. I don't know what the original owner had on the rear, but he had to widen the fender/rear end gap on the right side for the lift arm to hook to. He managed to warp the frame with the hydraulic power. I straightened it out with a 24" pipe wrench and a big hammer. It ain't perfect, but you can't see it.

No hitch here. I bolted 2 pcs of 2"angle iron on the side of the frame. I used an existing hole on the rear but had to drill another ahead of the rear axle. 3/4" treated plywood is the base for the sprayer. Nothing fancy, just functional. I may install a longer hose on the wand. If I have a lot of irregular areas to do, such as around the house, then I get my son to drive. For around the farm, I drove and sprayed with my left hand, hydro on right--works well.:beerchug:

Pics of the red paint.

Actually I'm going to put flat fan on the boom. I want that for spraying the farm roads and around the corn fields(I stay off the woods about 4-6 feet), and the riding trails the boys have in the woods.
I've got a good selection of old nozzles, probably use 8003 or 4. TSC carries a lot of accessories for these types of sprayers, think I even saw a manifold so you could rig it up to cut off individual nozzles or do multiple booms (a little much for a lawn mower). I even saw a tow type sprayer there that was 50-75 gallons. Built like a scaled down farm version with an electric pump. Nice looking rig for something like a SCUT.

If its front mounted you want to run, come pay me a visit. This ought to be right up your alley--covers 8 corn rows (38"). Sprayer is John Blue, ground drive. If you have ever drove an M, you can appreciate turning on a dime in
4th at full throttle while yanking the rope to disengage/engage the sprayer. Its the only one of these rigs I know of still running.

I'm in the process of building one of these too. I ordered an A-frame for my three point hitch from Extreme and going to build it off that. I wired in a 12 volt plug on the back and a switch on the dash to operate it. I'll upload some pictures when I get a little farther along.

It's been so hot around here lately it hard to get anything done, besides what has to be done. Plus the governor on my 129 went out so I'll be tearing into that too.

wow, I have never heard of anyone painting a red IH yellow. very cool and useful tractor all the same

Nice M Farmall John!

I've seen Dad rebuild quite a few of those old John Blue pumps.. He worked for a Farm supply dealer in the 60's 70's and 80's that had a bunch of those old ground drive pumps running.. he had a test stand and knew just how to set them up... good pumps!:biggrin2:

Send us some pics of the framework under your cub sprayer tank... id like to see how you supported it.. I'm guessing you have some angle braces back toward the bottom of the rear axle? Just curious.. now that Ive seen this you have motivated me.. I have several cubs sitting around doing nothing!

John Blue made some excellent equipment, as far as I know they still do, just a little more high tech.:biggrin2: Actually lots of the trailer type ground drive pumps in service here every spring for putting out nitrogen.

Back on topic, the frame is just 2" angle bolted on the outside of the Cadets chassis. I used one existing hole at the rear, had to drill one hole about in line with where the pump bolts to the trans. PLENTY of room to put this stuff on. I used bolts through the plywood into the "nuts" molded into the tank. Had to be real careful I didn't get too long of bolts. The tank has a groove molded in it for using straps, I may eventually add some plumbers strapping to help secure it. Currently still using the original battery clamps, may switch over to a trailer style plug in. Even thought about running wires to the PTO switch for an off and on, don't know if the fuse is heavy enough?:bigthink: Like I said earlier, nothing fancy here, this was for working and I needed it in a hurry. I mounted the tank about an inch from the fenders to keep the front end from getting very light.

Ok I see how you did it... very simple yet effective!:beerchug:
I have a tow behind sprayer rigged up on a Gravely.. SHHHH:biggrin2::biggrin2: Best thing I ever did is make a quick connect harness with a push pull switch on the dash... easy to cut the spray off and on when turning around!

Looks like it'll do well for ya John.:beerchug:
I've got myself a tank sprayer on my ATV. Mounted the tank on the front with the two nozzle boom outback.
I wanted the tank up front so I could see the amount left in the tank, and be able to open or close the valve, to change from wand to boom spray. I can't turn and look tight behind anymore, so this worked best.
I use it mainly for "trimming" around the house, and food plots.:beerchug:

Doing some tidying up on the 782 sprayer. Driveshaft and all components except the fan were junk. Ordered new rag joints, lock nuts, spirol pins, and some 4140ph to make a shaft out of--(bought enough for 2 future mahines:biggrin2:). No big deal to making the shaft, just drill 3 holes. The piece that goes on the pump needed help. The cast iron was wallered (technical term) out pretty bad. The pump shaft wasn't the worst, but showed damage. As best as I could mike it with the port lines in place, it was only worn down and tapered a small amount, makes sense because I would imagine the pump shaft is hardenend or case hardenend anyway. Regardless, it was well enough to leave alone. I took the part that goes on the pump shaft and bored it out for a custom bushing. Also, one of the hles for the spiral pin must have been .015 oversize--the shaft was whipping pretty good. So instead of picking up the existing holes I opted to install a new one, just bored it all the way with a carbide end mill. Spirol pin fits nice and tight now.
For my records, I made me a print for the shaft--and labeled it 1811.:bash2: Wasn't till yesterday that I realized that was the last machine I made a shaft for, I had forgotten about it till I stumbled onto the old shaft.

Nicely done!
Did you chose the angle to drill the new hole based on shaft rotation direction?Seems like it would make a difference which direction the load was being applied to the hole on, and it'd be better to drill it in a direction that left it more "meat" to push against.

I actually thought about that AFTER I had put the hole in. :bash2: Oh well, don't think it will bother anything, especially for the life this machine will be leading. I'm using longer pins anyway, because that's what McMaster had. Time will tell.

Well fix John :ThumbsUp:

Look like your having all the fun with your big boy tools. :beerchug:

nice little tractor. shame they painted over the red. looking for one of those in red for myself. maybe one day.

John,

Looks good! And i think it will work just fine especially with the intended use:biggrin2::biggrin2:.. But if not Jeff in PA makes a really nice coupler that fits deeper on the pump shaft and has set screws along with the spirol pin.. the set screws do a really nice job of stabilizing the coupler if your pump shaft has any wear at all.:beerchug:

I think the force on the offset hole may cause problems, why do you think they put it where it was instead of where it is now?

Can't see it making a difference, its just rotated, not what I would call offset. Like Gompers pointed out, should have rotated the other way, but whats done is done. From a machining standpoint the original hole location would be the simplest thing to do--no spotface, the hole doesn't come out the back on one side causing it to lead off and requiring something like an end mill to bore it. Same reason this part was cast, only 2 machining operations required---less machining and less time means cheaper. It also was a more "balanced" design, but not sure that is required. Pulleys, sprockets, etc are driven offset by a single key. I'm sure this part could have been keyed and held in with a set screw.

I did wonder what if you didn't drill the roll pin holes in the shaft in line with each other? Would that be like have a bent/twisted driveshaft or one that is assembled out of phase?:bigthink:

FINALLY, I was able to get the 782 out of the shop. Got the new driveshaft installed, runs nice and true. Everything is new, except the cast ends and bolts, I did use new locknuts. You can blow past $100 so quick rebuilding a driveline it will make your head spin.:bigeyes:
I bought enough material to make 2 more driveshafts and bought packs of roll pins and lock nuts, all from McMaster.
Put on an aftermarket fuel pump. Ready to go. Oh wait, lets check the hydro fluid. So low I couldn't touch it, decided to change it. It was aggravating but I was able to change it with the sprayer attached. Only had 4 or 5 qts in it.:bigeyes: Appears the notorious pump mounting gasket has a slight leak, although sitting in the shop for a month it didn't drip a spot larger than a quarter. Unless it turns out to be a problem, I'll let it "sweat". Because I'm anal, I refilled with Hytran and a Cadet filter. :biggrin2: I may have to make another 1 hr run for HyTran and engine oil before spring gets here.

Anyway, the 782 has been evicted from the shop--that's a good thing!:beerchug:

Hooray for another happy 782 in the world!:beerchug:

The tractor has lasted 30+ years the first go round, fixing it right as you have, It'll be ready for another 30!:beerchug:

Good to see your progress.:beerchug:

Good work John.:beerchug:
Also, good idea replacing those nuts. Cheap insurance.:biggrin2:

Thanks for letting us watch along via your photos and repairs.

What's next in the cub shop?

Nice work! :beerchug:

Rescue11 built this several years ago both sides fold it's a 3pt attachment.
If you wanted something to cover more area and removable..

Looks nice! We needed something more for wand use around buildings, ditches, fields, woodlines, etc. I only put 2 nozzles on the sprayer boom, that's just for driveway and farm road--make 2 passes. I put out about 5 tanks last year and barely used it over 1/2 the season. Kept things looking real nice around here though!

Aww ok I get it.
