Simple Roper Hydrostatic question
Roper LTH120AR Ser#1238SO1768, 12 HP Briggs 281707.
The Roper was given to me, and is the only Hydro I own, being a firm believer in manual transmissions as my land is very hilly. That being said, I do like the Roper as it's kind of a neat old (20+years) machine and just use it to pull around a garden cart and very occasionally do light mowing.
The trans control is a lever sticking out of the dash in a slot. Picture the letter "H" and remove the upper left and lower right "legs." the horizontal portion is neutral, the upper right is forward, the higher you go the faster you go, "ditto" the lower left which is reverse.
Probably due to age, when going forward, placing the control anywhere beyond the first "inch" of vertical travel it creeps back down unless you keep your hand on it. I've checked the manual and visually inspected to find somewhere to tighten or tension this lever and can find nothing. What I'm thinking of is filing a series of notches for the lever to rest in as it's spring loaded to the right and there's plenty of room to move it around. Being ignorant of small tractor hydros would that cause problems? I believe they have internal relief valves to avoid overpressurizing (sp?) ?
Thanks for your tiime,
