GR2110 - I'm not impressed.

reverse speed. as i see it.
The fwd pedal on the gr2110 moves the linkage by the fan blade further than reverse. thus more pump pressure for fwd. The direction is the same on the linkage pump mechanism to compare pedal stroke in fwd and rev.
It appears the stop bolt under the reverse is restricting travel .Should be able to adjust the reverse pedal stop bolt under the pedal and re-adjust the switch that the pedal hits in reverse getting more speed. But check with a dealer to see if this is a safety issue for speed. i like to see how things work ,and this is only my opinion.

I fixed mine except with one more step.Needed to grind the bottom rear of the pedal off to make it really open up the flow.Goes as fast in reverse as it goes forward,now.Likely engineered that the pedal hitting the floorboard would be the limiting factor,regardless of adjustment.Safety issue;full bore reverse,hard turn,foot slips off pedal,could throw you off the tractor.

Dont know how to post so I,ll use a reply.--- new gr2110 tractor
A week ago, I adjusted the stop bolt and backed up a steep grade about 35 feet. and 40 degrees or steeper. It,s steep. 3 1/2 hrs on tractor.

second cut today and after finishing- 2-- less than a acre hiily yards, I tried to back up the same hill. It was struggling at the bottom.
I checked the rear movement of stroke and still was the same.
After a few hours and everything was cooled down ,it went right up the hill in reverse just as it should.
Nice tractor but the hydraulics heat up and lose the ability to pump proper pressure. Kabota dropped the ball on this . Not hard to figure it,s heat related
must be hard on the seals etc.
Wonder how the pump will hold up over time?

thanks for info on the pedal locknut.

I have a very steep hill at the rear of my property to an upper kids play area. When I was purchasing my B21 I actually was at the dealer during a Kubota event and so had an opportunity to speak with a Kubota rep who seemed very knowledgeable.

He indicated that if I was going up a steep hill and the tractor was slowing down that I should actually reduce pressure on the HST pedal. This would reduce the amount of slippage in the HST and the B21 would go up the hill but at a slower pace in the same gear.

My hill is steep enough that the B21 would go up in mid range empty but with a full bucket I would have to use low range and a couple of times I tried the recommended technique and it worked. I have noticed the same thing with my B26. I don't know if this is your problem, but if you are not having problems with cool HST fluid, then I wonder if slippage is the problem once the fluid is hot. You might want to try using a little less pressure on the HST pedal and see if that helps.

 

[locknut]

Sounds normal to me.I always mow the front bank first,when the fluid is cool.It does lose power as it heats up.Probably normal for most hydro tractors.I make sure the fluid is topped off and change it every 100hrs.Hope it lasts a long time-expensive to rebuild.

 

[gunnyad]

I.m thinking of adding a finned cooler to the rear of the gr2110 hyd.
.There is a 6 inch or so rubber hose a the rear end ,facing inward toward the opposite rear tire. This should be a low pressure area. A finned cooler with a seperate 12 v. fan may extend pump life. Also give backup capabilities on hills,when hot.
does anyone plow snow with a rear blade in reverse ,any hills or flat? overheat?
Any ideas ,on cooling ? why worry about the warrantee ,the reverse issue doesn,t seemed to be covered for hilly terrain.

amsoil hyd fluid seems to have a better heat range, anyone try it?

I thought I had mine fixed up. But after mowing for over an hour it won't back up a small incline. I can't believe Kubota doesn't fix this problem. It is such a shame because I love most features of this tractor. But it isn't worth a crap if you have a lot of hills. I'm going to talk to the dealer and if can't get it fixed I'm going to contact Kubota and try to get a Kubota rep to come and try it and tell me that is the way it is suppoed to be.

Have you tried the synthetic fluid? I was wondering if that would help.

No, but do use the Kubota brand Super UDT.Gunny suggestion of an auxillary cooler with a fan sounds like a good idea.Don't know where I'd put it on mine.Open area underneath is filled with extra framework and a toobox

The cooler worked but what my friend And I found was that when He originally took the hose off the top tube ,no fluid came out the top from the pump, but slowly rose out the hose from the bottom.
With the cooler ,the steering was jerky at the start ,cut and was happy with the backing up results,but in the end ,found the jerky steering still there on cold start up ,so he pulled off the hose and found fluid came out the top tube ,the cooler somehow prevented the top tube from draining and caused the pump to retain fluid to chatter the steering ,maybe cooler needs to be lower equal to the fluid level. if the cooler was tilted backward and did not drain and held more oil than the top tube ,I suppose it could hold the top tube from draining . any ideas. maybe someday ,try again. .
how do I post A message without reply ,or quote?

 

[gunnyad]

My friend mounted the cooler horizontal, do to hose arraingment the top metal tractor tube , went to the bottom cooler inlet, and the cooler top outlet, to the bottom tractor metal tube.
this would keep the coolerfluid level full to the outlet ,while not running.
this could possible cause it to hold the top tube to pump with fluid causing the cold start steering chatter.

re-arrainging hoses may help and tilting the cooler for drainage.

Any comments.
wont get to try this for a while ,removed the cooler for now.
Friend is busy ,so dont know when we can get to it again, injury stops me from doing much .

 

[gunnyad]

cooling hydraulics on the gr2110:
After checking on hydraulic sites and thinking about it.
I feel that the hose length and cooler added in the hydraulics, restricts flow .
when removing the hyd cooler ,the steering will only once have a slight jerk till hyd gets moving. But with the cooler the jerky steering see to last for a while. not seeming good for the pump, and occurred again after sitting overnite.
maybe a small resoirvoir tank to dump into and have it drain down to a cooler and then drain into the tractor might work.
or larger ,oversized cooler lines. at this point i,m not sure.

Amsoil transmission /hydraulic fluid seems to help in the gr2110. Still gets hot but seems to maintain viscosity better. JMO

Have had my GR2110 for a little over a year now. For the most part I am a happy camper. My biggest complaint is I don't think the RPM's on the mower deck are high enough. When I get into higher grass the mowing results are iffy at times. When i say higher grass we are talking letting the grass grow 1.5 -2 weeks vs 1 week. When I take it in this fall for its maintenance I will have them look at it. I also have noticed how slow going in reverse is, but honestly there aren't really too many times when I want to go fast in reverse so it works out fine for me.

 

[flyingpostman]

I find this thread interesting. I have 3 acres and lots of hills so a zero turn mower was out, but I wanted something with a bit more oomph than a lawn tractor AND 4WD (and I didn't want to get a BX). In Canada they still sell the GF1800 which is a front mount mower tractor. I was looking at the GR2110, but the GF1800 comes with a 60" deck and has a faster ground speed. It can also reverse up one of my hills with a 35 degree slope in 4WD, with the mower running, and get this, it "only" has the 18HP diesel engine. It also reverses quite quickly too. I bought this unit to replace an old TG1860 diesel lawn tractor that was also gutless in reverse.

It has been quite a while since I have visited this forum. I have a Kubota GR2100, bought in 2004. It was (and still is) the only 4-wheel drive lawn tractor I have found. I have not considered the BX because I have no need for the 3-point hitch and the roll-bar is too high to get under my trees. For the most part I have been happy with it but it has had its problems. Initially I was not getting the hill climb (hydrostatic lock) I expected but eventually it was improved on by the local dealer's mechanic. It definitely climbs forward considerably better than backward. I did have to replace the clutchpack that services the mower deck at about 125 hours. I had to pay for it because it was 1 month past the extended warranty and my dealer would not go to bat for me with Kubota -- they knew there was a problem with the transmission and that Kubota had extended the warranty because of it and did not contact me. (last tractor and service he sells me period -- he is 8 miles from my house but there is another Kubota dealer 26 miles away.) It cost me over $800.00. I now pay a lot more attention to my hydrostatic fluid levels then I did before and it nows has over 200 hours on it.

Of course you have a unique problem. Nevertheless, I have had my Kubota GR2110 for 9 years. It always has and is still doing a fine job of mowing, hauling, and plowing snow. It has required only replacement of the parking brake gear due to abuse. Perhaps you should not say you would not recommend this tractor based solely on your personal experience. Based on my and others personal experiences, we highly recommend this tractor.

The problem with the GR 2100 is NOT a unique problem. I bought one in 2005 and had nothing but problems with it. There was definatly a design problem with the transmission.....which is why Kubota put out a retrofit transmission kit. The original transmission had bushings on the rear axle...the retrofit included two new case half's that had bearings for the axle,,,,the way it should have been originally. If you proved you had a problem Kubota would replace the transmission with this kit at no charge to the costumer...parts or labor, even if the until was out of warranty,,,,which tells me that Kubota KNEW they had a problem.

Mine started leaking when it had about 70 hours on it and even after they replaced the tranny, it leaked from somewhere else. In addition to this there were problems with the glide steer cables.....which is why they switched to a mechanical linkage later.

If you do a little research, you'll find there were many problems with the early GR's...which is why I traded mine in when it only had about 200 hours on it.

I like Kubota, but they missed the boat on this one. If you've had no trouble with yours count yourself very lucky...and in the minority. I hope it keeps working for you.

It is now almost 3 years later and I have replaced the GR2100 with a BX-2370. I have nothing to say bad about the BX except in one spot on my lawn it it too heavy. I have a natural spring seeping in the middle of the hill in front of my house; it did not bother the GR2100. The BX is 500lbs heavier and the 1st time I went over that spot the tractor slid right through went sideways for a short distance -- I'm glad I was wearing the seat belt and had the ROP fully extended. Unlike the GR2100 which went into hydrostatic lock at times on steep hills, this tractor has no barriers, at least on my property. Unfortunately, I can't mow the orchard because even folded down the ROP is too tall to get under the tree limbs.

We are talking about two very different tractors here. The GR2110 is an upgraded version of the GR2100; it does not have the same problems with the transmission.
