8030 and 2-105 Value

I have a 8030 and a 2-105 that sit in the back of the shed.  My 105 gets about 5 hrs a year on it.  The 8030 gets maybe 10-15 hrs a year.  Curious what you all think they are worth if I decide to sell.  8030 is 2wd/PS transmission/7000 hrs on tractor/In-frame overhaul around 6000 hrs/Paint is pretty good/windows good/ Recent cab kit/ Brand new rear tires (not installed yet/everything works as it should/ has fuel leak from injection pump that I will have fixed.  105 has 5000 hrs/ everything works/ new hydr pump a couple hours ago (upgraded to the higher output)/ tires real good. Paint is ok. LED lights all around.  I don't think it needs anything.  Cab kit is ok, tear in seat, but overall, good tractors.  Both for the most part are always stored in the shed.  Few oil leaks.  I worked hard on the 105 last year as it leaked everywhere and think I pretty much got them. 8030 really doesn't take any oil. When I was using the 105 more, maybe a quart here and there, but nothing serious.  Thoughts on value.  I'm looking at another tractor and thinking I got too many tractors already and get rid of 2 and buy 1.  I know I will miss these someday. And I just flat out of room and pain to leave stuff outside all winter working on projects. 

Could always just build a bigger shed! I have never said to myself, man I wish I had less tractors, but it might happen someday.

Ya, got 9 tractors and not sure my count is correct without walking thru the sheds. No I have 10 thinking about it with a 11th one probably coming.  I know there are 3 combines and my R50 also is going to go.  Another perfect example, put a head on and hit the field with the machine as it is in really good shape, but just takes up too much room and will only use if my 62's go down. Read somewhere that tractors are like guns, if you can count how many you got, you don't have enough. LOL.  I need a lean to on my shop and a another building and that should free up my 40x60 shop.  For the pump, had a pressure gauge on to set the compensator and added a shim to get the relief valve pressure correct. I did the work, but a sharp old white mechanic at the dealer worked with me to ensure I had correct pressures. I had a heck of a time finding a pump and more so I could find the updated pump, but not an adapter kit.  Robinson Implement in Iowa fixed me up for the adapter kit luckily.  

HERRS machine out of Kansas had a new pump.  I'm going off year old memory here too.  But it was a little higher output.  It mounted just fine, but needed a kit to adapt the connections over and think a small line got a plug.  1st call to HERRS and they were looking for a pump.  After a 2nd call to him to see if they could rebuilt my old pump (they can't get a kit) he said I can get you the newer style pump, but can't find a kit to adapt it.  I said, well at Robinson, they have a kit, but can't find a new style pump. He said call them and verify this part number and if so, immediately head there and get it.  He couldn't believe they had a kit as he was looking for them also.  So yes you can update to a later style pump.  Mine is roughly a 1978 if that matters. Not sure on them thru the years.
