The owners manual has a long section, with many pages, that lists the speeds in each of the 12 gears, for each of the different tractor HP's, with speeds for 6 different tire sizes available. It repeats this same information for the HST tractor HP's and tire sizes. For my tractor it lists the max speeds for each range for 6 different tire sizes in both forward and reverse. It's very thorough.

Took the tractor back to the selling dealer today and they replaced the loader valve. I didn't check out the operation of the new valve and just hauled the tractor over to the Massey dealer so they could give it a once over to see if they can find anything. The "check engine" light has come on twice and I want to find out what codes the computer kicks out. I also want them to run the tractor on the Dyno and check for proper hydraulic operation. It seems to me that the hydro is very loud but I've never operated one before so it could be normal.
I'll report back once I get more info from the Massey shop.

Well I heard back from the Massey service manager. They checked the hydraulic pressure and flow and found those to be within spec. Also checked the pressure relief settings and found those to be correct as well. BUT what they discovered was that the engine would sometimes bog down on its own. Some more checking and they found the rear remote valve was faulty and would sometimes cause a deadheading. They even disconnected the cable to see if it was a sticky cable but it still did it. This may be the cause of some or most of the issues I was experiencing. I now have a new valve being shipped.
Two other things I had them check:
1) The PTO would shut off if I had the tractor in neutral, the parking brake set and got off the seat.
2) The 3PTH lever would vibrate really bad and fall down on its own, which would cause the 3PTH to slowly lower whatever was attached to it.
They are checking for a faulty relay / switch for the PTO issue and found a service bulletin for the 3PTH lever. The fix for the lever is ......... bend the lever so it rubs on the side of the adjustment slot and put some foam between the lever and the edge of the slot. Unbelievable. I'd expect something like that from some no name import tractor ...... but from Massey.
So far I have discovered that the loader valve was faulty and needed to be replaced and the rear remote valve is faulty and needs to be replaced. Both of these were in service bulletins issued by Massey. These valves were replaced by different ones in the newer tractors but there was no recall to replace the defective ones. I guess they hoped people wouldn't discover the problem until the initial warranty was up and then the customer would have to pay to replace the defective valves. Luckily I got the expensive one replaced at someone else's cost.
I'm hoping this will be the last fix and all will be fine going forward because I really like the tractor. BUT I'm not impressed with the way Massey knowingly leaves defective materials and workmanship in service for the customer to fix at their cost.

Sounds like you are getting the tractor sorted out. Glad to hear that!!! Also, glad that you didn't have TO PAY FOR the expensive repair!!! So, was the check engine light a result of the engine bogging down because of the remote valve? Did it set a code in the computer?
I finally got the tractor back and here is what I have discovered.
1) The new loader valve that was installed by the selling dealer has not been adjusted properly. I don't have float function. I can feel the valve start to get to the detent but not quite. I will have to figure out how to adjust this myself, since I'm not going to load up the tractor and drive 100km (2 times) to have them do it.
2) The new remote valve now returns to center on its own but I have not noticed any difference in the overall performance of the tractor.
3) The check engine light came on 3 times on my first test drive of about 500 ft. I called the Massey service manager and he told me it was likely the seat switch kicking off as I bounced along the rough gravel driveway. I bypassed the seat switch and it hasn't happened since. Problem solved.
As far as my "lack of power" issue goes, I think most of it is related to my lack of experience with HST and trying to compare it to the Powershuttle that I had previously. I did some more reading and found the rated ground speeds for each of the ranges for the HST and for each if the gears (in each of the ranges) for the PowerShuttle. The Powershuttle has 3 ranges with 4 gears in each range and the HST also has 3 ranges but there is a HUGE difference in the range speeds between the 2. In reality to compare the 2 transmissions you need to compare the HST ranges to the Powershuttle gears in high range.
Here is the comparison of the rated top forward speeds (mph) of the 2 transmissions with R4-2 rear tires.
Powershuttle (high range)___________HST
1st gear___3.97___________________Low range 3.87
2nd gear__6.00___________________Mid range 8.33
3rd gear___9.39__________________High range 17.76
4th gear__14.84
I just need to adjust my thinking to suit.

Update:
I put more time on the tractor yesterday ( I now have 40 hrs on it, including the test drive) and I love this thing. Having a cab is awesome and the HST is a huge improvement for most (maybe all) of the stuff I do. It also seems that the tractor has a bit more power than before the remote valve replacement. Since that valve was replaced it runs smoother and gets much better fuel economy. I think the service manager was right about that. He said the remote valve bouncing back and forth would cause the engine to work harder and consume more fuel.
The big snow meltdown has started here, so yesterday I was moving my snow equipment to a storage location and moving a bunch of snow away from the house with the FEL. I look for excuses to use the new tractor. I used it for about 2 hours and was only wearing a T shirt and still warm. I had the heat switch turned to cold and the fan on medium to keep the inside cab temp comfortable. I tried the AC for a bit just to make sure it was working, since I never tried this on my test drive (it was -20C at the time and sure didn't need AC). When I got out of the cab I sure noticed how cold and windy it was but it was nice and toasty warm in the cab. There are still some odd hydraulic noises when using the loader and I'm pretty sure it is just that the valve needs adjustment. I did adjust the loader to get the float function to work but I may have moved the adjustment nut a bit too far. I need to play around with the 2 adjustments to see if there is a sweet spot for them.
I wish I would have made the move to a Cab and HST a long time ago.

Glad to hear the Tractor is working out for you! You're spot-on about the cab heat... T-shirt is the appropriate clothing choice even in negative temperatures. I think you'll continue to be happy with the choice as you continue getting used to HST.

Good luck with your 1749 hydro. Had a 1758 hydro that I just sent down the road. The hydro since new was weak in mid and high range. Would not load the engine in mid range or even spin tires on wet grass if trying to load bucket before hydro relief valve would release. Could not pull a 6 ft. digger only in low range at 3.5 MPH. Had it to two different AGCO dealers check the hydro. AGCO instructed the dealers to check hydro relief pressue and dyno the tractor HP. Both said it was in Spec. and as the tractor was designed. Had a 59 HP tractor that functioned like a 35 HP because hydro would not put power to the ground in anything but low range. Last fall had to replace the Turbo and deff fulters at 190 hrs. Tractor was gone waiting for parts for 6 weeks. AGCO changed the gearing in 2018 hydro models to lower speed in mid and high range knowing the hydro were not very usable in mid and high range. After much hastling with AGCO, they provided me with the new gear set the 2018 models have, put would not pay labor to install (about $1500). Tractor gone but still have the new gears. Picked up a good deal on a John Deere 4052 hydro with 37 hrs. Yanmar engine and hydraulics much smoother than the MF.
Still having some issues with the 1749 and decided I want a new tractor with full warranty in case something big goes wrong. I wanted to try a Massey 1760M but my local dealer didn't have one and there isn't one in BC to try. The nearest one is in Alberta and there is only one in the whole province. That was at least an 8 hr drive each way. No way that was going to happen. So I took a Kubota L6060 for a demo test at home and the power difference is very noticeable. I could climb up my driveway empty or working it, at almost twice the speed and the hydraulics are way smoother. I ended up trading in the Massey for a 2019 Kubota L6060.
