We have a reel mower we cut athletic fields with here at school, a toro reelmaster 2600-D with a 3 cyl perkins diesel, run and cuts like a champ.
Our athletic director typically cuts grass, she seems to work too hard doing that....thats another long story...
anyway - she came to me say that the mower was "hopping" in the forward movement, mmmm, hopping .....
This mower has a 7' triple reel deck(s) and EVERYTHING is hydraulically operated, the "hst" and the reels and the up and down movement is all hydraulically driven.
SO - I get on it , fire it up (engine runs perfectly) and there is no movement forward, rev ....nothing! The lever that makes the reals engage....nothing, the lever that makes the reels lift....nothing. There are no strange noises, no pump squeal ......nothing.
So......a day passes, and I am assuming that the pump is shot - and waiting for it to get fixed is like waiting for N Korea to play nice!
Then I see the mower has been moved about 20 feet - I know moving it without the bypass is not good......
so yesterday - I get on it, fire it up and it moves, and cuts as IF nothing has happened.......
SO I am perplexed to say the least.
She told me that she ran it for a long time when it started to hop.......then it sat 24 and did not work.
It has not been near freezing here at all.
The fluid and filters have NOT been changed in ......last couple hundred hours I know ( maintenance is something that does not get done - other than me changing the engine oil and greasing it twice a year)
I looked up the manual and did a search .....cant find anything related to the problem.
My only thoughts are there is an electrical overload-overheat relay that cut out and somehow stopped all fluid flow - I have no proof that "switch" exists btw............ or the pump was sucking air......
anyone have any thoughts as where to "look"
here are some pictures of the ol girl!

is the hydraulic pump vane or gear driven? If vane drive, the vanes could be worn out or sticking.
