ng on mower) is so much slower than the right,so i have to hold back the right arm just to stay straight,which causes me to go really slow. i cant afford to continue to take it to the shop right now, but i cant tolerate this anymore. is there an adjustment i can make w/ the left arm assembly , and if so, what do i do? i just started my own company and struggling until next season,PLEASE HELP!

Experienced gardeners share their insights in answering this question :
Lift the seat up and look for (rods) that run from the pump to the control sticks. There is a jam nut on these treaded rods, one for each hydro unit, use a marker and mark the position of the jam nut on the rod on the slow side, left you said. loosen the jam nut and turn the treaded rod a couple of turns one direction, then try the mower and see if it is faster on that side or slower, if it is slower then turn the treaded rod the oppisite direction that you just turned, If it is faster then it was before then adjust the rod till it is the same speed as the other side is. Tighten jam nut.

Zero-Turn Mowers: Purge Your Hydraulic Drive System. Zero turn hydrostatic transmission problems can start with air in the system, a condition known as cavitation. When the pump is full of air instead of oil, it can`t generate the pressure needed to provide power. This is pretty common in zero-turn mower transmissions.
Zero-turn mowers look a lot different than traditional riding mowers. You control the steering with levers on each side, rather than a steering wheel. While zero-turn mowers may look challenging to drive, they`re really very easy.
Why is My Zero Turn Mower Weak on One Side? Your zero turn mower is weak on one side because of one or more of many reasons: traction adjustment being wrong, dragging drum brake, bad dampers, incorrect balance, tire compression does not match, or there is air trapped in the hydrostatic motor.
In general, when the working pressure reaches the regulating pressure of the relief valve, the relief valve begins to overflow and the movement speed of the hydraulic cylinder slows down.
The most common causes of poor hydraulic performance are particulate contamination, water contamination, clogged filters, high fluid temperature and incorrect hydraulic fluids.
In most cars, small trucks and SUVs on the road today, there is a rack and pinion steering system. This converts the rotational motion of the steering wheel into the linear motion that turns the wheels and guides your path. The system involves a circular gear (the steering pinion) which locks teeth on a bar (the rack).
If the tire pressures are different on each side, it can cause one side of the mower to engage less than the other. To fix this problem, you must inspect if both tires have the same pressure using a tire gauge. Once you verify that they`re unmatched, you must inflate the tires with the necessary pressure.
That reduces their cost to build their mower but gives you zero additional value in your purchase. The dampers reduce operator fatigue by eliminating negative hydraulic-system feedback through the levers. They eliminate the “jerky” feel while performing tight, precise maneuvers around obstacles.
The most common cause of hydraulic cylinder failure is leaking seals, which not only allow critical fluids to leave the system (including lubricants) but allow damaging contaminants (water, air, and particles) to make their way inside the hydraulic cylinder.
One of the disadvantages of hydrostatic drives is that the majority of the oil stays in the loop and doesn`t return to the reservoir for cooling. One way to return some of the oil back to the tank is by using a hot oil shuttle valve.

I have a zero turn, liquid cooled exmark mower that has hyrdrolic steering. my problem is that when you want to go forward, the left side(sitting on mower) is so much slower than the right,so i have to hold back the right arm just to stay straight,which causes me to go really slow. i cant afford to continue to take it to the shop right now, but i cant tolerate this anymore. is there an adjustment i can make w/ the left arm assembly , and if so, what do i do? i just started my own company and struggling until next season,PLEASE HELP!

My husqvarna zero turn mower has an auto safety shut off. I have isolated 3 (Brake, Left control level, and Right contol lever)trying to see which one was faulty, but I’m not sure where to go next. When I took the brake off, the mower stalled so I held the safety button down and when the brake was off the engine stayed running. But when I pulled the Left or Right Control level to move, it shut off, so I held those down to see if I could see which one was faulty. The engine stayed running, so I couldn’t figure out which one was bad. Every thing stayed running until I engaged the mower deck, and then it shut down again. I gave up at that point and figured I needed an experts help! Thanks, Jon Sable
