Re: John Deere X300GT project

That's too bad the oil reservoir was cracked. Looks good though.

The reservoir is not expensive ($10.00) and it's better to be safe then sorry.

Of course I know the tractor is going to move faster than the shaft was moving in the video

Can you imagine we could drive our tractor with a cordless drill. :sidelaugh

Re: John Deere X300GT project

But who is going to hold the drill while you drive the tractor?

Re: John Deere X300GT project

OK back to business.

The k66Y pulley come with a different diameter and thickness, so to keep the original ratio (speed) between the motor and the tranny I have to install the K46 pulley

At the same time keep they original belt that come with the X300

And the finish result

Re: John Deere X300GT project

What would happen if you used the K66 pulley? Would you just have to get a different belt? Would it go faster?

Re: John Deere X300GT project

I`m thinking that your new 66 needs to be driven at it`s original design speed in order to perform properly. If I`m following correctly, you have installed the larger stock pulley from your 46. which will slow down the impeller. Assuming that both engine drive pulleys are the same, won`t this translate into lower ground speed and perhaps decreased power / hyd efficiency ?

Re: John Deere X300GT project

How did you release the internal brake? Without the drill power, can you turn both sides of the axle the same direction by using your hands?

The pulley of the K66Y is smaller (4.27) (the K46 is 4.9) so theoretically they input shaft will go slower and she is larger so that will mine to change the engine pulley to have a matching set for the belt.

The spec input speed of the K66 is 3400 RPM and 3000 RPM for the K46

So the way I did it they input shaft will turn 400 RPM less It is better then going to fast, slower a bit will not brake the internal part in the tranny but going faster is always risky

No you can move both sides of the axle the same direction by hand only.

In the video both side turn the same direction.

So if you used the K66 pulley and changed the engine pulley it will turn at 3400 rpm and go faster? Could you use an engine pulley from a G100?

The end result (speed of the tractor) will be negligible, in other word you will not really see the difference.

You could compensate by either increase tire size diameter or crank up a bit the engine RPM.

For The Kawasaki (FH491V) 17HP Twin John Deere spec the engine hight speed regime at 3400 RPM, Kawasaki say 3600 RPM for it.

Hello Stladrill!
I'm very happy that we have another member of this forum, except me, who is trying to make garden tractor of X300/x320.
The first thing that I notice when I try to do a K58A to k66R swap was that I have only one pair of mounting holes on each side of tranny. That is not the case with K 66Y.
The another thing was that there's different position of input shaft in the K 66R. Distance from the inputshaft to the middle of the axes is cca 4 centimeters longer than on the K 58. It means that if I install it on the exactly same position my input shaft will be positioned cca 4 cm to the front of the tractor. This issue make me wonder will the belt tensioner do the job. because of that I decided to make another rear hitch plate, with two pairs of mounting holes, and in that case I can simply move the tranny to the rear pairs of holes, so my belt and pullyes stays the same, and my belt tensioner can do the job.

On that new hitch plate I predicted a hitch ball.
I will send pictures when it will be done.

Yes it is a solution to back off the tranny.

This is my next step to measure and compare the distance between the component (lever, center input shaft/axle,,,,)

The thing whit the K66R, was built with a different upper case kit (the top of the tranny) most to accommodate zero turn mower.

The K66Y is built with the same configuration of the K71/72 tranny.

Re: John Deere X300GT project

How did you get the nut off the input shaft to change the pulley, is there a way to lock the shaft ?

My small shop is equip with 50 gallon air compressor.

I use a 3/8 air impact gun and hold the pulley with my hand.
