Hi Guys,

I have two 1862's one has the super steer axel the other does not.
Any idea why?
The one with the super steer axel has a deep deck on it (GT 46) the other one has a 82 series style 44 inch deck on it.
Does the deep deck require the additional ground clearance provided by the super steer axel?
If not does anyone know what the purpose of the super steer axel was?

Thanks,
Ike

Ike,
There are two different axles used on the Cyclops models. The early ones used an axle that was the same height as the earlier WF and 82 series. The later one raised the front end about 2". Both can be considered "Super Steer" axles because they both steer much tighter than the earlier models. The 1862 would have came with the lower one. My guess is that someone added the later high axle to one of your tractors.

The high axle came out in 1993 on the 1863 and 1864 and was to give more clearance for the new (at the time) 48" and 54" decks. The 46" deck worked with the lower axle but the higher one gave it more lift height as well.

In addition to Todd's points, if you move the decks between the two tractors, the rear "deck lift assembly" gets attached to the mule drive at a different point to adjust for the different tractor height. This is outlined in one of the Cub service bulletins, that I hope we get back.

Also, when Cub raised the regular GTs higher, it allowed them to offer the 551 snow blower to fit both GT and SGT tractors without an extension kit as had been required with the older blowers (450/451) for use on the SGTs.

Tom s see you can teach me things I never knew that the 551 blower was made for the 1863 and supers without the ext kit the later axle also swings the front tires forward I like that we can share info without being worried who will see it

Ray - I just like having you out there to keep an eye on me... I want to be set straight if I get it wrong!

Todd, Tom, Ray,

Thanks for all the scoop on these axels. I’d like to put the 46GT deck on the 1862 with the 82 series axel. I plan to put a CH22 in it, should make a nice mowing machine. The one with the higher axes also has front ports. Perhaps it will become my work tractor. I may look around for a blower for it. What would be the best, a 551?

Thanks again for your help,

Ike

Ike the blower depends on what pto you are useing if its a 4 in you need a 450 if you use the 6 in you need a 451 or 551 all are hard to find around here now

Ike - Measure your pto pulleys on both tractors; everything with Serial #821,059 should have a 4.6" pulley; all later tractors have some form of something around 6" or slightly larger. The 46" deck was sold as two different models; #336 for the older small pto and #321 for the newer large pto. If you run the old deck with the newer large pto, it will run too fast. If you run the newer deck with the older small pto, the deck will run very slow. Someone may have already converted your deck before you got it, so be careful about trusting the nameplate on the deck; measure the top pulley of the double pulley as well to verify the size.

I would not increase the deck speed; the speed difference is substantial, and you risk worn parts and injury by overspeeding the deck. Running the deck too slow will result in poor performance. The decks work fine at the speed they were designed for.

Now to digress... I use the 46" on my 1861 for leaf grinding. Cub offered bagging blades or regular side discharge blades for these decks. I use the bagging blades but have blocked off the discharge with a brownie pan that looks like Cub made it to fit! If you don't block the discharge, the leaves don't stay under the deck long enough to get ground up. In the areas that get too thick after grinding, I install the bagger and suck those up.

I used to bag all of them, but grinding as many as possible has saved much getting on and off the tractor to empty the bagger. It takes more seat time, as the yard needs more driving over, but I will take more seat time over emptying bags any day.

For grass, I like the 50C deck better. The 46" was designed to be a good bagging deck, and it is. Although the 46" cuts fine, it windrows the grass real bad when you discharge the clippings. The 50" spreads them real nice and I have never had it windrow.

The tractor with the low axel has the smaller PTO.

The one with the high axel has a 6 inch PTO, a 46GT series 321 deck with 5” pulley on it. Also it has the mower height adjustment on the rear of the tractor just like the 1863’s etc. The Model # is 142-683-100 Ser # 830-713. I wonder if this one was close to the end of the production of the 1862’s and had some of the 1863 features on it??

Thanks again,

Ike

Ike - Please slow down...your asking much in rapid succesion!

First, I think I should have said measure the bottom of the double stack pulley on the decks, not the top. I have the older 336 deck and I know that the double stack is correct because I had to replace it with new from Cub last year. The new measured the same as my old; 5" top pulley, 5-1/2" bottom pulley. The 321 deck should have different dimensions on the double stack pulley; if your top is the same as mine, your bottom of the double stack should be smaller on the 321.

So first of all, if you want to use your 46" GT (321) deck with the older 4.6 pto, you will need to get a new double stack pulley from the 336. It is still available as a kit with bearings and spacer (759-3652, $155). Or, you can decide to just use the deck on the tractor it came on (1862). (Your Factory and Serial numbers indicate that this was an 1862, model year 1992). Based on the serial number, it should have the large pto that is on it, which is correct for the 321 deck. (In 1993 the 1861 became the 1863, and the 1862 became the 1864 with the new axle; sounds like you got the axle before they changed the model to an 1864, or someone before you did surgery on the front end.)

Now, from your next topic... What is the 48 GT deck you refer to? What is the model number on it?

Tom,

The bottom pulley on the 46GT deck is 4.5 inches.

The model # on the 48GT deck is 317190.

Hope you have a great weekend, nice WX here.

Thanks,

Ike

Replacing the 1862 759-3579 axle with the 1863 713-3100

Hello,

I have made a swap of my broken axle,(759-3579).

I did not get spindles with the used (713-3100).

I placed the (703-1748-49) old knuckles in the (713-3100) axle Now on the tractor.
There is a space difference of the knuckles on the 1863 Axle.
Could an additional thrust bearing make the difference or do I need the exact knuckles for the 1863 axle?

Also confused by the posts on this thread in consideration of my 46" GT deck and fitting the 1863 axle.
It looks fine. Deck is on will hook up the belt tomorrow.

Please help!

David - Welcome to the forum!

Sounds like you may need to make spacers or find the newer spindles to match the new front axle you installed. Ray Weaver and Rich Patton would be two excellent sources for used parts; their contact info can be found in the vendor section from the main menu of the forum. Someone else with more experience than I with the older vs. newer spindles may chime in. Ray Weaver sometimes jumps in, right about now....

As far as the mower deck goes... I thought some of the hanging frames had lower holes in the front mule drive for the higher axle, but I looked at the directions for the 336 (46" GT deck) and only see one set for Supers and one set for regular GT, so you are probably fine. Just measure your blade tips to flat floor and make sure that the front of the blade is about 1/8" lower than the rear, as per the mower deck manual. Mower deck manual can be found in the "Documents and Manuals" link in the blue banner center of every forum page.

Again, welcome, and let us know how you do.

Tom

Thanks Tom,

As for the deck I think is fine. The Knuckle/Spindles I call them are a different part number for each the old broken Axle and the 1863 used axle I just place under the tractor. The tractor does turn and maneuver well however the gaps could betaken up with either thicker thrust bearings of additional bearings of the same size. I will be checking the vendor section soon on this as I need to be working this tractor asap.

Thanks again,

David
