Hi gang, I have a geared pistol grip walk-behind that I purchased at the end of last season and I am in a quandry about the adjustments of the brakes. I have a Toro Proline 48 geared pistol grip fixed deck WB which is very similar to the Exmark Metro 48. When adjusting the brakes according to the directions, it seems that I cannot engage the parking brakes easily. The following occurs: 1. I adjust the control rods so there is 1/8" of play between the rod that goes through the control rod and the base of the parking brake/neutral thumblocks (that was hard to describe). Otherwise my drive belts were not fully engaging and I was getting pulling to one side. 2. I adjusted the tightness of the brakes using the wingnuts on either side of the machine so that I can engage the parking brakes relatively easily. I have to pull the brake levers to the grip to apply the brake on either side. While still being able to engage the parking brakes easily, I cannot make either wheel lock up. 3. I then adjusted the brakes so that either wheel will lock up when the brake levers are almost to the grip. This still requires almost a full "throw" of the brake lever to get the mower to turn 180 degrees. However in this setting I cannot engage the parking brakes without really pulling on the levers with all my strength and engaging the brake lock with my other hand. So it seems there must be a happy medium in there somewhere but I have yet to find it. Am I doing something incorrect, or do I just need to wait for the machine to break in a little bit? It has about 8 hours of use on it. I hadn't expected for there to be such fine tuning required - adjusting one rod 1/2 turn, then adjusting the wingnuts 1/4 turn at a time to find the sweet spot. I am also somewhat concerned that I might be doing something wrong and the brakes really should be engaging closer to the initial pull point of the lever travel - but this makes the parking brakes useless to me. Either I need to fix this, or I just need to get larger forearms! Maybe they'll develop on their own after a season of pulling on the pistol grips!
