And here is a photo of the underside of my deck. As you can see, the blades swing freely. If the bolts were tight against the blades, they could not swing.

The "bushings" on the 48" brush mowers appear to be nothing more than a bit of cut off pipe or thick walled tubing. I assume the larger models are similar.

(Watch me be wrong.) :eek: :rolleyes:

ID..........to fit the bolt
OD.........to fit the blade
Length....slightly longer than the blade thickness

Probably cheaper and quicker to make your own rather than ordering from Tazewell.

I have a box of them sitting at the farm.. I would send them to you if I was there. I made new, thicker, heavier, harder blades for my PT. Had to replace the bushings at that time...

Also, when I did this I used hardened bolts, a bit of blue goo, and hardened washers.

You mean a 2X4 on the bolt head(s) that aren't there because they were sheared off when the blades kicked back :)

Actually now, my blades (2nd set) are so bent that they go over the stop bolts and wedge under the one-another for some very exciting unbalanced brushcutter bucking.

Sedge: Thanks for the "lock" tip, I haven't though of it. There used to be a "PT operating tips" thread. That would be a good one to add for those of us who tend to overlook the obvious.

My wheels are definitely plumbed in series LL and RR (only ipsalateral side turns when up off all fours), but if one wheel starts spinning, most of the power goes to that wheel.

Shouldn't fluid follow the path of least resistance??? I didn't think it was a malfunction, just the nature of the beast.

Sounds like the 1430 is a very good landscaping tractor. I like the 1445 but it just seems too big for us.
I'm wondering if there's a way to get more lift out of it (counterweights maybe?).

Remember, this tractor is FAST!!! take smaller bites.

Gotcha on that.
I have a chance to go see a 1430 and a 1445 (same owner) Friday if the weather permits :mad:

Do your wheel motor have case drains? If they don't, it is impossible for most of the power to go to the wheel without traction. Since it doesn't have traction, it can't do any work and won't use any power, except for the little bit required to turn it over. Almost all of the power going to that side of the tractor will be used by the wheel that still has traction.

Remember, wheel speed is almost exclusively dependent upon hydraulic fluid flow rate. Wheel motors plumbed in series have to have the same flow rate, therefore they must turn at the same rate, therefore you can't have one spin while the other doesn't.

You may see a slight bit of wheel "cogging" as the pressure changes in the hose between the motors due to the unloading of the wheel without traction, but it will be limited to something less than a full revolution. The hose acts as a bit of an accumulator as it absorbs the increased pressure from the unloaded wheel.

Once a wheel breaks loose, more power is applied to the other wheel on that side, and there is some risk that it will also spin, even though it has more traction. Could that be what is happening?

If you do have case drains, the wheel without traction could be bypassing, sending a lot of fluid out through the drain. In that case, you would probably experience wheel spin.

My wheel motors do not have case drains, so I don't have any operating experience with that type and am merely hypothesizing. :D

Edit: I don't understand what you mean by only ipsalateral side turns when up off all fours. I take ipsalateral to mean same or one side. If the machine is jacked up so that all four wheels are off the ground, all four should rotate at the same speed.

Ipsalateral! You must be in the medical field. ;)

To clarify (hard to do without a reference point): When turning by hand

Regarding my wheel motors, they have 3 hoses. I presume one is the case drain. Funny, until now, I was a little proud I had the motors with the case drain. Thought of it as an upgrade. Apparently, it's not.

Interesting. You might give Terry a call and see if he can confirm my theory.

I think with some motors the case drains are optional. Might be worth checking to see if that is the case with your motors, and if so, if it would be prudent to try blocking them off.

There is also the question of how much they should be bypassing. Perhaps it is excessive for some reason. I'm a bit out of my depth, but I don't think you really should lose the limited slip function because of bypassing through the case drain.

I have to say, I've wished for a long time that I had purchased a 1430 instead of a 425. I still do, but not so much anymore. The 425's limited slip function works extremely well.

My 1430 has no case drains and it behaves like Snowridge describes. I can grab hold a log heavy enough to lift the rear wheels off of the ground and the tractor will still move. Can't steer, but the tractor will go.
